-# Contributing
+# Optimism monorepo contributing guide
 
-🚨 Before making any non-trivial change via Pull Request, please first open an issue 
-describing the change to solicit feedback and guidance. This will increase the 
-likelihood of your Pull Request getting merged.
+**Please read our [general contributing guide](https://github.com/ethereum-optimism/.github/blob/master/CONTRIBUTING.md) before continuing**
 
-## Contributing in Issues
 
-For any issue, there are fundamentally three ways an individual can contribute:
+These packages only require 1 reviewer (all other packages require 2 reviewers, unless the changes do not affect production or test code). 
+- packages/smock
+- packages/core-utils
+- packages/hardhat-ovm
+- packages/common-ts
+- examples
+- integration-tests 
 
-1. By opening the issue for discussion: For instance, if you believe that you
-   have uncovered a bug in Optimism, creating a new issue in this repository's
-   issue tracker is the way to report it.
 
-2. By helping to triage the issue: This can be done by providing
-   supporting details (a test case that demonstrates a bug), providing
-   suggestions on how to address the issue, or ensuring that the issue is tagged
-   correctly.
-
-3. By helping to resolve the issue: Typically this is done either in the form of
-   demonstrating that the issue reported is not a problem after all, or more
-   often, by opening a Pull Request that changes some bit of something in
-   Optimism in a concrete and reviewable manner.
-   
-**Anybody can participate in any stage of contribution**. We urge you to
-participate in the discussion around bugs and participate in reviewing PRs.
-
-### Asking for General Help
-
-If you have reviewed existing documentation and still have questions or are
-having problems, you can open an issue asking for help.
-
-In exchange for receiving help, we ask that you contribute back a documentation
-PR that helps others avoid the problems that you encountered.
-
-### Submitting a Bug Report
-
-When opening a new issue in the Optimism issue tracker, users will be presented
-with a [basic template][template] that should be filled in. If you believe that you have
-uncovered a bug, please fill out this form, following the template to the best
-of your ability. Do not worry if you cannot answer every detail, just fill in
-what you can.
-
-The two most important pieces of information we need in order to properly
-evaluate the report is a description of the behavior you are seeing and a simple
-test case we can use to recreate the problem on our own. If we cannot recreate
-the issue, it becomes impossible for us to fix.
-
-In order to rule out the possibility of bugs introduced by userland code, test
-cases should be limited, as much as possible, to using only Optimism APIs.
-
-See [How to create a Minimal, Complete, and Verifiable example][mcve].
-
-[mcve]: https://stackoverflow.com/help/mcve
-[template]: .github/PULL_REQUEST_TEMPLATE.md
-
-### Triaging a Bug Report
-
-Once an issue has been opened, it is not uncommon for there to be discussion
-around it. Some contributors may have differing opinions about the issue,
-including whether the behavior being seen is a bug or a feature. This discussion
-is part of the process and should be kept focused, helpful, and professional.
-
-Short, clipped responses—that provide neither additional context nor supporting
-detail—are not helpful or professional. To many, such responses are simply
-annoying and unfriendly.
-
-Contributors are encouraged to help one another make forward progress as much as
-possible, empowering one another to solve issues collaboratively. If you choose
-to comment on an issue that you feel either is not a problem that needs to be
-fixed, or if you encounter information in an issue that you feel is incorrect,
-explain why you feel that way with additional supporting context, and be willing
-to be convinced that you may be wrong. By doing so, we can often reach the
-correct outcome much faster.
-
-### Resolving a Bug Report
-
-In the majority of cases, issues are resolved by opening a Pull Request. The
-process for opening and reviewing a Pull Request is similar to that of opening
-and triaging issues, but carries with it a necessary review and approval
-workflow that ensures that the proposed changes meet the minimal quality and
-functional guidelines of the Optimism project.
-
-## Pull Requests
-
-1. Ensure that tests pass and code is lint free.
-2. Update the README.md if any changes invalidate its current content.
-3. Include tests for any new functionality.
-4. Reference relevant issues in your PR comment.
-
-### Commands
-
-This section lists some commonly needed commands.
-
-```
-# compile typescript
-yarn build
-# typescript lint checks
-yarn lint
-# typescript lint fixes
-yarn lint:fix
-# typescript unit tests
-yarn test
-# typescript integration tests
-yarn test:integration
-# l2geth lints
-make lint
-# l2geth tests
-make test
-```
-
-### Tests
-
-If the change being proposed alters code (as opposed to only documentation for
-example), it is either adding new functionality to Optimis or it is fixing
-existing, broken functionality. In both of these cases, the pull request should
-include one or more tests to ensure that functionality does not regress in the future.
-
-#### Unit Tests
-
-Functions which have very specific tasks should be unit tested. We encourage using
-table tests to cover a large number of cases in a succinct readable manner.
-
-#### Integration tests
-
-Integration tests go in the `integration-tests` package.
-
-The best strategy for writing a new integration test is to look at existing
-integration tests and follow the style. A common pattern is to 
-instantiate an Optimism environment first by bringing the docker-compose network
-up (via `docker-compose up`) and then inside your test environment via [`OptimismEnv.new()`](https://github.com/ethereum-optimism/optimism/blob/18c122debc6b1acbd56be2d33c99109dc8f006fa/integration-tests/test/shared/env.ts#L23)
-
-### Commits
-
-It is a recommended best practice to keep your changes as logically grouped as
-possible within individual commits. There is no limit to the number of commits
-any single Pull Request may have, and many contributors find it easier to review
-changes that are split across multiple commits.
-
-That said, if you have a number of commits that are "checkpoints" and don't
-represent a single logical change, please squash those together.
-
-Note that multiple commits often get squashed when they are landed (see the
-notes about [commit squashing](#commit-squashing)).
-
-#### Commit message guidelines
-
-
-A good commit message should describe what changed and why. While we do not enforce it, 
-we would prefer it if your commit messages follow the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) convention.
-
-1. The first line should:
-
-  * contain a short description of the change (preferably 50 characters or less,
-    and no more than 72 characters)
-  * be entirely in lowercase with the exception of proper nouns, acronyms, and
-    the words that refer to code, like function/variable names
-  * be prefixed with the name of the sub package being changed and start with an imperative verb. 
-
-  Examples:
-
-  * batch-submitter: introduce ENS querying for names and addresses
-  * perf(integration-tests): tune down poll intervals
-
-2. Keep the second line blank.
-3. Wrap all other lines at 72 columns (except for long URLs).
-4. If your patch fixes an open issue, you can add a reference to it at the end
-   of the log. Use the `Fixes: #` prefix and the issue number. For other
-   references use `Refs: #`. `Refs` may include multiple issues, separated by a
-   comma.
-
-   Examples:
-
-   - `Fixes: #1337`
-   - `Refs: #1234`
-
-Sample complete commit message:
-
-```txt
-package: explain the commit in one line
-
-Body of commit message is a few lines of text, explaining things
-in more detail, possibly giving some background about the issue

-
-### Opening the Pull Request
-
-From within GitHub, opening a new Pull Request will present you with a
-[template] that should be filled out. Please try to do your best at filling out
-the details, but feel free to skip parts if you're not sure what to put.
-
-[template]: .github/PULL_REQUEST_TEMPLATE.md
-
-### Discuss and update
-
-You will probably get feedback or requests for changes to your Pull Request.
-This is a big part of the submission process so don't be discouraged! Some
-contributors may sign off on the Pull Request right away, others may have
-more detailed comments or feedback. This is a necessary part of the process
-in order to evaluate whether the changes are correct and necessary.
-
-**Any community member can review a PR and you might get conflicting feedback**.
-Keep an eye out for comments from code owners to provide guidance on conflicting
-feedback.
-
-**Once the PR is open, do not rebase the commits**. See [Commit Squashing](#commit-squashing) for
-more details.
-
-### Commit Squashing
-
-In most cases, **do not squash commits that you add to your Pull Request during
-the review process**. When the commits in your Pull Request land, they may be
-squashed into one commit per logical change. Metadata will be added to the
-commit message (including links to the Pull Request, links to relevant issues,
-and the names of the reviewers). The commit history of your Pull Request,
-however, will stay intact on the Pull Request page.
-
-## Reviewing Pull Requests
-
-**Any Optimism community member is welcome to review any pull request**.
-
-All Optimism contributors who choose to review and provide feedback on Pull
-Requests have a responsibility to both the project and the individual making the
-contribution. Reviews and feedback must be helpful, insightful, and geared
-towards improving the contribution as opposed to simply blocking it. If there
-are reasons why you feel the PR should not land, explain what those are. Do not
-expect to be able to block a Pull Request from advancing simply because you say
-"No" without giving an explanation. Be open to having your mind changed. Be open
-to working with the contributor to make the Pull Request better.
-
-Reviews that are dismissive or disrespectful of the contributor or any other
-reviewers are strictly counter to the Code of Conduct.
-
-When reviewing a Pull Request, the primary goals are for the codebase to improve
-and for the person submitting the request to succeed. **Even if a Pull Request
-does not land, the submitters should come away from the experience feeling like
-their effort was not wasted or unappreciated**. Every Pull Request from a new
-contributor is an opportunity to grow the community.
-
-### Review a bit at a time.
-
-Do not overwhelm new contributors.
-
-It is tempting to micro-optimize and make everything about relative performance,
-perfect grammar, or exact style matches. Do not succumb to that temptation.
-
-Focus first on the most significant aspects of the change:
-
-1. Does this change make sense for Optimism?
-2. Does this change make Optimism better, even if only incrementally?
-3. Are there clear bugs or larger scale issues that need attending to?
-4. Is the commit message readable and correct? If it contains a breaking change
-   is it clear enough?
-
-Note that only **incremental** improvement is needed to land a PR. This means
-that the PR does not need to be perfect, only better than the status quo. Follow
-up PRs may be opened to continue iterating.
-
-When changes are necessary, *request* them, do not *demand* them, and **do not
-assume that the submitter already knows how to add a test or run a benchmark**.
-
-Specific performance optimization techniques, coding styles and conventions
-change over time. The first impression you give to a new contributor never does.
-
-Nits (requests for small changes that are not essential) are fine, but try to
-avoid stalling the Pull Request. Most nits can typically be fixed by the Optimism
-Collaborator landing the Pull Request but they can also be an opportunity for
-the contributor to learn a bit more about the project.
-
-It is always good to clearly indicate nits when you comment: e.g.
-`Nit: change foo() to bar(). But this is not blocking.`
-
-If your comments were addressed but were not folded automatically after new
-commits or if they proved to be mistaken, please, [hide them][hiding-a-comment]
-with the appropriate reason to keep the conversation flow concise and relevant.
-
-### Be aware of the person behind the code
-
-Be aware that *how* you communicate requests and reviews in your feedback can
-have a significant impact on the success of the Pull Request. Yes, we may land
-a particular change that makes Optimism better, but the individual might just not
-want to have anything to do with Optimism ever again. The goal is not just having
-good code.
-
-### Abandoned or Stalled Pull Requests
-
-If a Pull Request appears to be abandoned or stalled, it is polite to first
-check with the contributor to see if they intend to continue the work before
-checking if they would mind if you took it over (especially if it just has nits
-left). When doing so, it is courteous to give the original contributor credit
-for the work they started (either by preserving their name and email address in
-the commit log, or by using an `Author: ` meta-data tag in the commit.

-## Quickstart
+## Contributing
 
-### Installation
+Read through [CONTRIBUTING.md](./CONTRIBUTING.md) for a general overview of our contribution process.
+Follow the [Development Quick Start](#development-quick-start) to set up your local development environment.
 
-Dependency management is done using `yarn`. 
+### Good First Issues
 
-```bash
-git clone git@github.com:ethereum-optimism/optimism.git
-cd optimism
-yarn
-```
+You can find good first issues by filtering for the ["good first issue" tag on our issues page](https://github.com/ethereum-optimism/optimism/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) or alternatively by taking a look at our [Good First Issues project board](https://github.com/orgs/ethereum-optimism/projects/23).
+If you'd like to tackle one of these issues, please leave a comment and [assign yourself to the issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/assigning-issues-and-pull-requests-to-other-github-users#assigning-an-individual-issue-or-pull-request).
+This helps prevent two people accidentally working on the same task at the same time.
+
+### Changesets
+
+We use [changesets](https://github.com/atlassian/changesets) to manage releases of our various packages.
+You *must* include a `changeset` file in your PR when making a change that would require a new package release.
+
+Adding a `changeset` file is easy:
+
+1. Navigate to the root of the monorepo.
+2. Run `yarn changeset`. You'll be prompted to select packages to include in the changeset. Use the arrow keys to move the cursor up and down, hit the `spacebar` to select a package, and hit `enter` to confirm your selection. Select *all* packages that require a new release as a result of your PR.
+3. Once you hit `enter` you'll be prompted to decide whether your selected packages need a `major`, `minor`, or `patch` release. We follow the [Semantic Versioning](https://semver.org/) scheme. Please avoid using `major` releases for any packages that are still in version `0.y.z`.
+4. Commit your changeset and push it into your PR. The changeset bot will notice your changeset file and leave a little comment to this effect on GitHub.
+5. Voilà, c'est fini!
+
+### Rebasing
 
-After installing the dependencies, you must also build them so that the typescript
-is compiled down to javascript:
+We use the `git rebase` command to keep our commit history tidy.
+Rebasing is an easy way to make sure that each PR includes a series of clean commits with descriptive commit messages
+See [this tutorial](https://docs.gitlab.com/ee/topics/git/git_rebase.html) for a detailed explanation of `git rebase` and how you should use it to maintain a clean commit history.
+
+## Development Quick Start
+
+### Dependencies
+
+You'll need the following:
+
+* [Git](https://git-scm.com/downloads)
+* [NodeJS](https://nodejs.org/en/download/)
+* [Yarn](https://classic.yarnpkg.com/en/docs/install)
+* [Docker](https://docs.docker.com/get-docker/)
+* [Docker Compose](https://docs.docker.com/compose/install/)
+
+### Setup
+
+Clone the repository, open it, and install nodejs packages with `yarn`:
 
 ```bash
-yarn build
+git clone git@github.com:ethereum-optimism/optimism.git
+cd optimism
+yarn install
 ```
 
-### Unit tests
+### Building the TypeScript packages
 
-All tests are run in parallel using `lerna`:
+To build all of the [TypeScript packages](./packages), run:
 
 ```bash
-yarn test
+yarn clean
+yarn build
 ```
 
-When you want to run tests only for packages that have changed since `master` (or any other branch)
-you can run `yarn lerna run test --parallel --since master`
+Packages compiled when on one branch may not be compatible with packages on a different branch.
+**You should recompile all packages whenever you move from one branch to another.**
+Use the above commands to recompile the packages.
 
-### Integration Tests
+### Building the rest of the system
 
-#### Running the integration tests
-
-The integration tests first require bringing up the Optimism stack. This is done via
-a Docker Compose network. For better performance, we also recommend enabling Docker 
-BuildKit
+If you want to run an Optimistic Ethereum node OR **if you want to run the integration tests**, you'll need to build the rest of the system.
 
 ```bash
 cd ops
-export COMPOSE_DOCKER_CLI_BUILD=1
+export COMPOSE_DOCKER_CLI_BUILD=1 # these environment variables significantly speed up build time
 export DOCKER_BUILDKIT=1
 docker-compose build
-cd ../integration-tests
-yarn build:integration
-yarn test:integration
 ```
 
-#### Locally testing and re-building specific services
+This will build the following containers:
 
-If you want to make changes to any of the containers, you'll have to bring one down,
-rebuild it, and then bring it back up.
+* [`builder`](https://hub.docker.com/r/ethereumoptimism/builder): used to build the TypeScript packages
+* [`l1_chain`](https://hub.docker.com/r/ethereumoptimism/hardhat): simulated L1 chain using hardhat-evm as a backend
+* [`deployer`](https://hub.docker.com/r/ethereumoptimism/deployer): process that deploys L1 smart contracts to the L1 chain
+* [`dtl`](https://hub.docker.com/r/ethereumoptimism/data-transport-layer): service that indexes transaction data from the L1 chain
+* [`l2geth`](https://hub.docker.com/r/ethereumoptimism/l2geth): L2 geth node running in Sequencer mode
+* [`verifier`](https://hub.docker.com/r/ethereumoptimism/go-ethereum): L2 geth node running in Verifier mode
+* [`relayer`](https://hub.docker.com/r/ethereumoptimism/message-relayer): helper process that relays messages between L1 and L2
+* [`batch_submitter`](https://hub.docker.com/r/ethereumoptimism/batch-submitter): service that submits batches of Sequencer transactions to the L1 chain
+* [`integration_tests`](https://hub.docker.com/r/ethereumoptimism/integration-tests): integration tests in a box
 
+If you want to make a change to a container, you'll need to take it down and rebuild it.
 For example, if you make a change in l2geth:
 
 ```bash
@@ -98,9 +145,130 @@ docker-compose build -- builder batch_submitter
 docker-compose start batch_submitter
 ```
 
+Source code changes can have an impact on more than one container.
+**If you're unsure about which containers to rebuild, just rebuild them all**:
+
+```bash
+cd ops
+docker-compose down
+docker-compose build
+docker-compose up
+```
+
+Finally, **if you're running into weird problems and nothing seems to be working**, run:
+
+```bash
+cd optimism
+yarn clean
+yarn build
+cd ops
+docker-compose down -v
+docker-compose build
+docker-compose up
+```
+
+#### Viewing docker container logs
+
 By default, the `docker-compose up` command will show logs from all services, and that
 can be hard to filter through. In order to view the logs from a specific service, you can run:
 
-```
+```bash
 docker-compose logs --follow <service name>
 ```
+
+### Running tests
+
+Before running tests: **follow the above instructions to get everything built.**
+
+#### Running unit tests
+
+Run unit tests for all packages in parallel via:
+
+```bash
+yarn test
+```
+
+To run unit tests for a specific package:
+
+```bash
+cd packages/package-to-test
+yarn test
+```
+
+#### Running integration tests
+
+Follow above instructions for building the whole stack.
+Build and run the integration tests:
+
+```bash
+cd integration-tests
+yarn build:integration
+yarn test:integration
+```

+
+### Overview
+
+We generally follow [this Git branching model](https://nvie.com/posts/a-successful-git-branching-model/).
+Please read the linked post if you're planning to make frequent PRs into this repository (e.g., people working at/with Optimism).
+
+### The `master` branch
+
+The `master` branch contains the code for our latest "stable" releases.
+Updates from `master` always come from the `develop` branch.
+We only ever update the `master` branch when we intend to deploy code within the `develop` to the Optimistic Ethereum mainnet.
+Our update process takes the form of a PR merging the `develop` branch into the `master` branch.
+
+### The `develop` branch
+
+Our primary development branch is [`develop`](https://github.com/ethereum-optimism/optimism/tree/develop/).
+`develop` contains the most up-to-date software that remains backwards compatible with our latest experimental [network deployments](https://community.optimism.io/docs/developers/networks.html).
+If you're making a backwards compatible change, please direct your pull request towards `develop`.
+
+**Changes to contracts within `packages/contracts/contracts/optimistic-ethereum` are usually NOT considered backwards compatible and SHOULD be made against a release candidate branch**.
+Some exceptions to this rule exist for cases in which we absolutely must deploy some new contract after a release candidate branch has already been fully deployed.
+If you're changing or adding a contract and you're unsure about which branch to make a PR into, default to using the latest release candidate branch.
+See below for info about release candidate branches.
+
+### Release new versions
+
+Developers can release new versions of the software by adding changesets to their pull requests using `yarn changeset`. Changesets will persist over time on the `develop` branch without triggering new version bumps to be proposed by the Changesets bot. Once changesets are merged into `master`, the bot will create a new pull request called "Version Packages" which bumps the versions of packages. The correct flow for triggering releases is to re-base these pull requests onto `develop` and merge them, and then create a new pull request to merge `develop` onto `master`. Then, the `release` workflow will trigger the actual publishing to `npm` and Docker hub.
+
+### Release candidate branches
+
+Branches marked `regenesis/X.X.X` are **release candidate branches**.
+Changes that are not backwards compatible and all changes to contracts within `packages/contracts/contracts/optimistic-ethereum` MUST be directed towards a release candidate branch.
+Release candidates are merged into `develop` and then into `master` once they've been fully deployed.
+We may sometimes have more than one active `regenesis/X.X.X` branch if we're in the middle of a deployment.
+See table in the **Active Branches** section above to find the right branch to target.
+
+## Additional Reference Material
+
+### Running contract static analysis
+
+We perform static analysis with [`slither`](https://github.com/crytic/slither).
+You must have Python 3.x installed to run `slither`.
+To run `slither` locally, do:
+
+```bash
+cd packages/contracts
+pip3 install slither-analyzer
+yarn test:slither
+```

+# gas-oracle
+
+This service is responsible for sending transactions to the Sequencer to update
+the L2 gas price over time. It consists of a set of functions found in the
+`gasprices` package that define the parameters of how the gas prices are updated
+and then the `oracle` package is responsible for observing the Sequencer over
+time and send transactions that actually do update the gas prices.
+
+### Generating the Bindings
+
+Note: this only needs to happen if the ABI of the `OVM_GasPriceOracle` is
+updated.
+
+This project uses `abigen` to automatically create smart contract bindings in
+Go. To generate the bindings, be sure that the latest ABI and bytecode are
+committed into the repository in the `abis` directory.
+
+Use the following command to generate the bindings:
+
+```bash
+$ make binding
+```
+
+Be sure to use `abigen` built with the same version of `go-ethereum` as what is
+in the `go.mod` file.
+
+### Building the service
+
+The service can be built with the `Makefile`. A binary will be produced
+called the `gas-oracle`.
+
+```bash
+$ make gas-oracle
+```
+
+### Running the service
+
+Use the `--help` flag when running the `gas-oracle` to see it's configuration
+options.
+
+```

+# utils
+
+This package is meant to hold utilities used by
+[Optimistic Ethereum](https://github.com/ethereum-optimism/optimism) written in
+Golang.
+
+## Packages
+
+### Fees
+
+Package fees includes helpers for dealing with fees on Optimistic Ethereum
+
+#### `EncodeTxGasLimit(data []byte, l1GasPrice, l2GasLimit, l2GasPrice *big.Int) *big.Int`
+
+Encodes `tx.gasLimit` based on the variables that are used to determine it.
+
+`data` - Calldata of the transaction being sent. This data should *not* include the full signed RLP transaction.
+
+`l1GasPrice` - gas price on L1 in wei
+
+`l2GasLimit` - amount of gas provided for execution in L2. Notably, accounts are charged for execution based on this gasLimit, even if the gasUsed ends up being less.
+
+`l2GasPrice` - gas price on L2 in wei
+
+#### `DecodeL2GasLimit(gasLimit *big.Int) *big.Int`
+
+Accepts the return value of `eth_estimateGas` and decodes the L2 gas limit that
+is encoded in the return value. This is the gas limit that is passed to the user
+contract within the OVM.

+# @eth-optimism/integration-tests
+
+## Setup
+
+Follow installation + build instructions in the [primary README](../README.md).
+Then, run:
+
+```bash
+yarn build:integration
+```
+
+## Running tests
+
+### Testing a live network
+
+Create an `.env` file and fill it out.
+Look at `.env.example` to know which variables to include.
+
+Once you have your environment set up, run:
+
+```bash
+yarn test:integration:live
+```
+
+You can also set environment variables on the command line instead of inside `.env` if you want:
+
+```bash
+L1_URL=whatever L2_URL=whatever yarn test:integration:live
+```
+
+Note that this can take an extremely long time (~1hr).

 # Changelog
 
+## 0.4.4
+
+### Patch Changes
+
+- 0404c964: Allow zero gas price transactions from the `OVM_GasPriceOracle.owner` when enforce fees is set to true. This is to prevent the need to manage an additional hot wallet as well as prevent any situation where a bug causes the fees to go too high that it is not possible to lower the fee by sending a transaction
+- c612a903: Add sequencer fee buffer with config options `ROLLUP_FEE_THRESHOLD_UP` and `ROLLUP_FEE_THRESHOLD_DOWN` that are interpreted as floating point numbers
+
+## 0.4.3
+
+### Patch Changes
+
+- 6e2074c5: Update the `RollupClient` transaction type to use `hexutil.Big`
+
+## 0.4.2
+
+### Patch Changes
+
+- 7e04137d: Handle errors correctly in the RollupClient and retry in the SyncService when initially attempting to connect to the DTL
+
+## 0.4.1
+
+### Patch Changes
+
+- 40b99a6e: Add new RPC endpoint `rollup_gasPrices`
+
+## 0.4.0
+
+### Minor Changes
+
+- e04de624: Add support for ovmCALL with nonzero ETH value
+
+### Patch Changes
+
+- 01646a0a: Add new config `ROLLUP_GAS_PRICE_ORACLE_OWNER_ADDRESS` to set the owner of the gas price oracle at runtime
+- 8fee7bed: Add extra overflow protection for the DTL types
+- 5fc728da: Add a new Standard Token Bridge, to handle deposits and withdrawals of any ERC20 token.
+  For projects developing a custom bridge, if you were previously importing `iAbs_BaseCrossDomainMessenger`, you should now
+  import `iOVM_CrossDomainMessenger`.
+- 257deb70: Prevent overflows in abi encoding of ovm codec transaction from geth types.Transaction
+- 08873674: Update queueOrigin type
+- 01646a0a: Removes config options that are no longer required. `ROLLUP_DATAPRICE`, `ROLLUP_EXECUTION_PRICE`, `ROLLUP_GAS_PRICE_ORACLE_ADDRESS` and `ROLLUP_ENABLE_L2_GAS_POLLING`. The oracle was moved to a predeploy 0x42.. address and polling is always enabled as it no longer needs to be backwards compatible
+- 0a7f5a46: Removes the gas refund for unused gas in geth since it is instead managed in the smart contracts
+- e045f582: Adds new SequencerFeeVault contract to store generated fees
+- 25a5dbdd: Removes the SignatureHashType from l2geth as it is deprecated and no longer required.
+
+## 0.3.9
+
+### Patch Changes
+
+- f409ce75: Fixes an off-by-one error that would sometimes break replica syncing when stopping and restarting geth.
+- d9fd67d2: Correctly log 'end of OVM execution' message.
+
+## 0.3.8
+
+### Patch Changes
+
+- 989a3027: Optimize main polling loops
+- cc6c7f07: Bump golang version to 1.15
+
+## 0.3.7
+
+### Patch Changes
+
+- cb4a928b: Make block hashes deterministic by using the same clique signer key
+- f1b27318: Fixes incorrect type parsing in the RollupClient. The gasLimit became greater than the largest safe JS number so it needs to be represented as a string
+- a64f8161: Implement the next fee spec in both geth and in core-utils
+- 5e4eaea1: fix potential underflow when launching the chain when the last verified index is 0
+- 1293825c: Fix gasLimit overflow
+- a25acbbd: Refactor the SyncService to more closely implement the specification. This includes using query params to select the backend from the DTL, trailing syncing of batches for the sequencer, syncing by batches as the verifier as well as unified code paths for transaction ingestion to prevent double ingestion or missed ingestion
+- c2b6e14b: Implement the latest fee spec such that the L2 gas limit is scaled and the tx.gasPrice/tx.gasLimit show correctly in metamask
+
+## 0.3.6
+
+### Patch Changes
+
+- f091e86: Fix to ensure that L1 => L2 success status is reflected correctly in receipts
+- f880479: End to end fee integration with recoverable L2 gas limit
+
+## 0.3.5
+
+### Patch Changes
+
+- d4c9793: Fixed a bug where reverts without data would not be correctly propagated for eth_call
+- 3958644: Adds the `debug_ingestTransactions` endpoint that takes a list of RPC transactions and applies each of them to the state sequentially. This is useful for testing purposes
+- c880043: Fix gas estimation logic for simple ETH transfers
+- 467d6cb: Adds a test for contract deployments that run out of gas
+- 4e6c3f9: add an env var METRICS_ENABLE for MetricsEnabledFlag
+
+## 0.3.4
+
+### Patch Changes
+
+- e2b70c1: Don't panic on a monotonicity violation
+
+## 0.3.3
+
+### Patch Changes
+
+- f5185bb: Fix bug with replica syncing where contract creations would fail in replicas but pass in the sequencer. This was due to the change from a custom batched tx serialization to the batch serialzation for txs being regular RLP encoding
+
+## 0.3.2
+
+### Patch Changes
+
+- 20242af: Fixes a bug in L2geth that causes it to skip the first deposit if there have been no deposits batch-submitted yet
+- cf3cfe4: Allow for dynamically set configuration of the gasLimit in the contracts by setting the storage slot at runtime
+- de5e3dc: Updates `scripts/start.sh` with the mainnet config by default
+
+## 0.3.1
+
+### Patch Changes
+
+- 9231063: Prevent montonicity errors in the miner
+
+## 0.3.0
+
+### Minor Changes
+
+- b799caa: Updates to use RLP encoded transactions in batches for the `v0.3.0` release
+
+### Patch Changes
+
+- b799caa: Add value parsing to the rollup client
+- b799caa: Removes the extra setting of the txmeta in the syncservice and instead sets the raw tx in the txmeta at the rpc layer
+- b799caa: Fill in the raw transaction into the txmeta in the `eth_sendTransaction` codepath
+- b799caa: Add support for parsed revert reasons in DoEstimateGas
+- b799caa: Update minimum response from estimate gas
+- b799caa: Add value transfer support to ECDSAContractAccount
+- b799caa: Ignore the deprecated type field in the API
+- b799caa: Return bytes from both ExecutionManager.run and ExecutionManager.simulateMessage and be sure to properly ABI decode the return values and the nested (bool, returndata)
+- b799caa: Block access to RPCs related to signing transactions
+- b799caa: Add ExecutionManager return data & RLP encoding
+- b799caa: Update gas related things in the RPC to allow transactions with high gas limits and prevent gas estimations from being too small
+- 9b7dd4b: Update `scripts/start.sh` to parse the websocket port and pass to geth at runtime
+- b799caa: Remove the OVMSigner
+- b799caa: Prevent 0 value transactions with calldata via RPC
+
 ## 0.2.6

+
+The `ops/docker-compose-replica-service.yml` docker-compose project runs a local replica of the OMGC Rinkeby l2geth. This service allows you run a local copy of the L2, which is useful for generating analyics for blockexplorers.
+
+## Prerequisites
+
+\- docker
+\- docker-compose
+
+## Start Replica service
+
+### Configuration
+
+Replace `INFURA_KEY` with your own key in [docker-compose-replica-service.yml](.ops/docker-compose-replica-service.yml). You can get a free Infura key from https://infura.io.
+
+### Start the docker

+
+The `ops/docker-compose-verifier-service.yml` docker-compose project runs a local Verifier of the OMGX Rinkeby l2geth. The verifier looks at transactions and computes state roots.

+# Developing for OMGX on Windows
+
+## Prequisites
+
+- User folder can't have a space
+	- A lot of the other programs we're using can't handle a space in paths.  
+	So make sure there's no spaces for your users folder.
+- [Windows Terminal](#windows-terminal)
+- [Git](#git)
+- [Docker](#docker)
+- [NVM](#nvm)
+- [Yarn](#yarn)
+
+### Windows terminal
+
+Windows terminal is a great substitute for terminal on MacOS/Linux. First download windows terminal from [here](https://www.microsoft.com/en-us/p/windows-terminal/9n0dx20hk701#activetab=pivot:overviewtab).  
+Now that you have it installed we're going to install [Ubuntu](https://ubuntu.com/tutorials/ubuntu-on-windows#1-overview). Ubuntu creates a WSL2 environment for us to develop and it's on bash! Follow all the instructions from the link it's pretty straightforward to follow this guide. Once you have Ubuntu we're going to do everything from there not from powershell or cmd because they don't have access to all the bash commands. Make sure for all the other steps that you're running Windows Terminal as an administator as it'll make everything a lot easier. To do that right click on the app and then run as administrator.
+
+### Git
+
+Git should already be installed on your Ubuntu server but in case it's not follow [this](https://www.digitalocean.com/community/tutorials/how-to-install-git-on-ubuntu-18-04-quickstart) guide to get it up and running. 
+
+### Docker
+
+Install Docker from [here](https://docs.docker.com/docker-for-windows/install/). Follow through the instructions and restart your computer. If you run into this error:  
+> `Hardware assisted virtualization and data execution protection must be enabled in the BIOS`
+
+You're going to want to restart your computer and hold down **esc, f1, f2, f3, f4, f8 or delete** depending on your chip. It should tell you waht to hold when you're restarting to enter your bios settings. Then you're going to want to enable virtualization from here. This setting may be hidden under advanced &#8594; CPA configuration and then virtualization. Save this and then Docker should be up and running!
+
+### NVM 
+
+On your Ubuntu terminal **running as an admin** run the following command to instal cURL:
+> `sudo apt-get install curl`
+
+Then install nvm (node version manager):
+> `curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash`
+
+To verify installation, enter: `command -v nvm`. This should return 'nvm', if you receive 'command not found' or no response at all, close your current terminal, reopen it, and try again.
+
+You can then use `nvm install [node-version]` to install whatever version of node you want. We recommend 14.17.3. Then use `nvm use [node-version]` to use that as your default. You can read more about NVM [here](https://github.com/nvm-sh/nvm). If you ran into any issues installing a lot of troubleshooting options can be found there as well.
+
+### Yarn
+
+Installing yarn is super easy with all the infrastructure we have use:
+
+>`npm install --global yarn`
+
+## All Done! 
+
+You should have everything you need to follow the rest of the tutorial [here](https://github.com/omgnetwork/optimism/). Good luck and have fun developing on L2!

+Thu June 24
+
+Greetings from your engineering team. We have been heads' down the last few weeks, to get many basic pieces for OMGX into place and stable. The most visible parts of this are an increasingly stable rinkeby testnet (https://rinkeby.omgx.network) and a working webwallet (aka gateway) with swap on/off and farming at https://webwallet.rinkeby.omgx.network. 
+
+## 1. Optimism Platform/Foundation
+
+The Optimism team continues to move rapidly, whilst producing very high quality code and many new useful features and improvements, such as a simplified and more elegant approach to token bridges, as well as extensive infrastructure dedicated to making L2s financially viable, for example by providing accurate price data for the sequencer and to all users.   
+
+## 2. Production / webscale
+
+* Under the hood, much effort has been devoted to web-scale production deployment of rollups - you can follow along here: https://github.com/omgnetwork/optimism/pull/46. The production rinkeby testnet currently runs on AWS EC2, which is stable but less scalable. A major next step will be to flip the switch, and transition to the AWS ECS Cloudformation system and all its associated CI/CD infrastructure and real time health monitoring. If response times start to degrade, e.g. when users are transferring funds across the chains, then we need to know about that within a few seconds, ideally. 
+
+* On a more basic level, our major goal is to have a system that (1) gracefully responds to restart of one or more subservices, without getting confused, and (2) that can recover to last-known-good state automatically after unexpected failure of one of more subservices. 
+
+## 3. User experience / front end
+
+* Although the webwallet works (https://webwallet.rinkeby.omgx.network), the user experience remains rudimentary. This is not just a challenge for us, but for all L2s and multichain situations. The key question is - how do we make using an L2 as easy and intuitive as possible? Two front-end engineers started last week, and are working with community members and UI designers to develop a good way to make L2s intuitive. The good news is that many people have more than one bank account (savings and checking, for example), so they are already used to the notion of using different accounts for different purposes. However, they are *not* used to having to reconfigure their banks's settings when they e.g. want to transfer funds from one account to another - this should just really happen with minimal user reconfiguration. You can follow along on the Pull Requests (https://github.com/omgnetwork/optimism/pulls); front-end focused work is growing quickly.
+
+* Closely related to the UI, is our solution for fast on/off, which consists of deploying liquidity pools across the chains - i.e. we represent moving funds to L2 as a swap, where a person swaps L1 ETH for L2 wETH, and where ETH and wETH never actually move across the chain boundaries. It's just like Uniswap, except that the two liquidity pools are not in one contract, but in two contracts, one on the L1 and the other one on the L2. This feature is live, and you can already earn Rinkeby ETH by staking, which provides liquidity for easy swap on/off: https://webwallet.rinkeby.omgx.network - click *Farm* on the top tab. Note that contract improvements are pending, and that the contracts have not yet been audited. 
+
+* Blockexplorer. A blockexplorer is vital, and there is a simple one you can look at here: https://blockexplorer.rinkeby.omgx.network/?network=OmgX. However, we will soon transition to an industry-leading blockexplorer, so you have all the functions you expect and we do not have to maintain our own blockexplorer. Related to the blockexplorer is a feature everyone expects - reliable transaction history, so they can easily see their transactions and get reliable updates about their deposits and withdrawals.
+
+* Hardware wallet support. One of the gaping holes in the current webwallet/gateway is the complete lack of support for hardware wallets - our first step will be to add Ledger Nano support (https://github.com/omgnetwork/optimism/issues/117). 
+
+## 4. Security

+* Verifiers
+* Automatic Fraud Proving and Recovery

+# Overall Setup
+
+Clone the repository, open it, and install nodejs packages with `yarn`:
+
+```bash
+git clone git@github.com:omgnetwork/optimism.git
+cd optimism
+yarn clean
+yarn install
+yarn build
+```
+
+Build and run the entire stack:
+
+```bash
+$ cd ops
+$ BUILD=1 DAEMON=0 ./up_local.sh
+```
+
+Helpful commands:
+
+* _Running out of space on your Docker, or having other having hard to debug issues_? Try running `docker system prune -a --volumes` and then rebuild the images. 
+* _To (re)build individual base services_: `docker-compose build -- l2geth` 
+* _To (re)build individual OMGX services_: `docker-compose -f "docker-compose-omgx-services.yml" build -- omgx_message-relayer-fast` Note: First you will have to comment out various dependencies in `docker-compose-omgx-services.yml`.
+
+### Running unit tests
+
+To run unit tests for a specific package:
+
+```bash
+cd packages/package-to-test
+yarn test
+```
+
+### Running integration tests
+
+```bash
+cd integration-tests
+yarn build:integration
+yarn test:integration
+```
+
+## Front End Development
+
+Start a local L1/L2. 
+
+```bash
+$ cd ops
+$ BUILD=1 DAEMON=0 ./up_local.sh
+```
+
+Typically, you will only have to build everything once, and after that, you can save time by setting `BUILD` to `2`. Then, open a second terminal window and navigate to `packages/omgx/wallet-frontend`, and run
+
+```bash
+$ yarn get_artifacts #this will get all the contract artifacts - note that this will only work correctly if you ran `yarn build` at the top level per instructions
+$ yarn build
+$ yarn start
+```
+
+and the frontend should start up in a local browser. You can also develop on the Rinkeby testnet - in that case, you do not need to run a local L1/L2. If you would like to do that, just change the `.env` settings:
+
+```bash
+# This is for working on the wallet, pointed at the OMGX Rinkeby testnet
+REACT_APP_INFURA_ID=
+REACT_APP_ETHERSCAN_API=
+REACT_APP_POLL_INTERVAL=20000
+SKIP_PREFLIGHT_CHECK=true
+REACT_APP_WALLET_VERSION=1.0.10

+Clone the repository, open it, and install nodejs packages with `yarn`:
+
+```bash
+git clone git@github.com:omgnetwork/optimism.git
+cd optimism
+yarn clean
+yarn install
+yarn build
+```
+With all this done we can move on to actually spinning up a local version of the Optimism L1/L2.
+  
+**NOTE: You should recompile all packages whenever you move from one  branch to another.**  
+Use the below commands to recompile the packages.
+
+<!-- Normally, after you have built the docker images once, all you have to do is to run:
+
+```bash
+$ BUILD=0 DAEMON=0 ./up_local.sh
+```
+
+and your computer will use the docker images you built earlier.  -->
+
+Note: _Running out of space on your Docker, or having other having hard to debug issues_? Try running `docker system prune -a --volumes` and then rebuild the images. 
+
+## Starting a local basic Optimism L1/L2
+
+You can change the BUILD and DAEMON values to control if everything is rebuilt (`BUILD=1`, very slow), and if you want to see all the debug information (`DAEMON=0`)
+
+**Before running any Docker related commands make sure you have Docker up and running.**
+
+
+```bash
+cd ops
+export COMPOSE_DOCKER_CLI_BUILD=1 # these environment variables significantly speed up build time
+export DOCKER_BUILDKIT=1
+docker-compose build 
+docker-compose up -V
+```
+
+If you run into issues errors when running `docker-compose build` restart Docker before trying anything else. 
+
+The `-V` setting is critical, since otherwise your Docker images may have stale information in them from previous runs, which will confuse the `data-transport-layer`, among other things. 
+
+## (Re)Building the entire system or parts of the base L1/L2
+
+If you want to run an Optimistic Ethereum node OR **if you want to run the integration tests**, you'll need to build the rest of the system.
+
+If you want to make a change to a container, you'll need to take it down and rebuild it.
+For example, if you make a change in l2geth:
+
+```bash
+cd ops
+docker-compose stop -- l2geth
+docker-compose build -- l2geth
+docker-compose start l2geth
+```
+
+For the typescript services, you'll need to rebuild the `builder` so that the compiled
+files are re-generated, and then your service, e.g. for the batch submitter
+
+```bash
+cd ops
+docker-compose stop -- batch_submitter
+docker-compose build -- builder batch_submitter
+docker-compose start batch_submitter
+```
+
+Source code changes can have an impact on more than one container.
+**If you're unsure about which containers to rebuild, just rebuild them all**:
+
+```bash
+cd ops
+docker-compose down
+docker-compose build
+docker-compose up
+```
+
+Finally, **if you're running into weird problems and nothing seems to be working**, run:
+
+```bash
+cd optimism
+yarn clean
+yarn build
+cd ops
+docker-compose down -v
+docker-compose build
+docker-compose up
+```
+
+## (Re)Building the entire system or parts of the OMGX contracts and services
+
+```bash
+cd ops
+export COMPOSE_DOCKER_CLI_BUILD=1 # these environment variables significantly speed up build time
+export DOCKER_BUILDKIT=1
+docker-compose build 
+docker-compose -f docker-compose.yml -f docker-compose-omgx-services.yml up -V
+```
+
+To build individual OMGX services:
+
+```bash
+docker-compose -f "docker-compose-omgx-services.yml" build -- omgx_message-relayer-fast
+```
+
+**Note: First you will have to comment out various dependencies in the `docker-compose-omgx-services.yml`.**
+
+#### Viewing docker container logs
+
+By default, the `docker-compose up` command will show logs from all services, and that
+can be hard to filter through. In order to view the logs from a specific service, you can run:
+
+```bash
+docker-compose logs --follow <service name>
+```
+
+### Running unit tests
+
+Before running tests: **follow the above instructions to get everything built.** Run unit tests for all packages in parallel via:
+
+```bash
+yarn test
+```
+
+To run unit tests for a specific package:
+
+```bash
+cd packages/package-to-test
+yarn test
+```
+
+### Running integration tests
+
+Follow above instructions for building the whole stack. Build and run the integration tests:
+
+```bash
+cd integration-tests
+yarn build:integration
+yarn test:integration
+```
+
+## Front End Development
+
+Start a local L1/L2. 
+
+You can change the BUILD and DAEMON values to control if everything is rebuilt (`BUILD=1`, very slow), and if you want to see all the debug information (`DAEMON=0`).
+
+```bash
+$ cd ops
+$ BUILD=1 DAEMON=0 ./up_local.sh
+```
+
+Typically, you will only have to build everything once, and after that, you can save time by setting `BUILD` to `2`. In that case, we'll use the docker images you built earlier.
+
+```bash
+$ cd ops
+$ BUILD=2 DAEMON=0 ./up_local.sh
+```
+
+Then, open a second terminal window and navigate to `packages/omgx/wallet-frontend`, and run
+
+```bash
+$ yarn get_artifacts #this will get all the contract artifacts - note that this will only work correctly if you ran `yarn build` at the top level per instructions
+$ yarn build
+$ yarn start
+```
+
+and the frontend should start up in a local browser. You can also develop on the Rinkeby testnet - in that case, you do not need to run a local L1/L2. If you would like to do that, just change the .env settings:
+
+```bash

+REACT_APP_INFURA_ID=

+# Service maintenance
+
+## Docker containers
+
+We have six main containers and five secondary containers that provide the monitor and subgraph services.
+
+### Main containers
+
+* [omgx/deployer-rinkeby](https://hub.docker.com/layers/omgx/deployer-rinkeby/production-v1/images/sha256-8ca509eb7a830ee862318225a2d5558f868d139a745edaff448ec3ccb90965e8?context=repo)
+
+  It serves `addresses.json` and `state-dump.latest.json` files so that l2geth container and data-transport-layer can fetch the `ADDRESS_MANAGER_ADDRESS` and `ABI` of L1 pre-deployed contracts.
+
+  Normally, this container uses about **15MB** memory.
+
+* [omgx/l2geth](https://hub.docker.com/layers/156092279/omgx/l2geth/production-v1/images/sha256-d5f099b01629da9ca93af25705d326d90bb7d100695e0a66cc920871705ff890?context=repo)
+
+  The l2geth container takes around 500MB memory. For safety and maintenance reasons, we should allocate **1GB** of memory to this service.
+
+  > Note: We didn't see a large increase in memory usage of **l2geth** when we ran the performance test.
+
+* [omgx/data-transport-layer](https://hub.docker.com/layers/156092207/omgx/data-transport-layer/production-v1/images/sha256-07d4415aab46863b8c7996c1c40f6221f3ac3f697485ccc262a3a6f0478aa4fb?context=repo)
+
+  The data-transport-layer syncs L1 and provides the index service. It only uses about **50MB** of memory.
+
+* [omgx/batch-submitter](https://hub.docker.com/layers/156091606/omgx/batch-submitter/production-v1/images/sha256-b3e61c1350b94cca73853867e1267e6f0e197ffbf7661f76c5c373e85eb3e70f?context=repo)
+
+  The batch submitter submits TX and state root batches to CTC and SCC contracts. It takes about **100MB** of memory.
+
+* [omgx/message-relayer](https://hub.docker.com/layers/156091959/omgx/message-relayer/production-v1/images/sha256-52ae4dbe41895c331ee3dc05955ad8c50c1319f91aaf3b4747d3ded2305382b4?context=repo) and [omgx/message-relayer-fast](https://hub.docker.com/layers/156091184/omgx/message-relayer-fast/production-v1/images/sha256-4e973130ca9cd5704ae3ce83f8c01682851b73835753268203bba91df7213167?context=repo)
+
+  Both message relayers need at least **1GB** of memory. It will restart when they approach the memory usage around **3.5GB**. It's better to give them at least **4GB** memory, so they won't restart frequently.
+
+### Secondary containers
+
+Our main services won't be affected by these secondary services, so it's safe for them to reboot when they have any problems.
+
+* Graph-node, postgres, ipfs
+* omgx/monitoring
+* omgx/dummy-transaction
+

+
+> NOTE:
+>
+> `omgx/l2geth`: it's the most important service, so we should give as much memory as we can.
+>
+> `omgx/message-relayer-fast` and `omgx/message-relayer` : both message relayers can stop due the OOM issue. Giving it **4GB** memory can reduce the number of times that it needs to restart. 
+>
+> [**IMPORTANT**] When `omgx/message-relayer-fast` and `omgx/message-relayer` restart, they scans all L2 blocks and check if there is a cross domain message and if the message is relayed to L1. It takes about 5 mins to sync 4K L2 blocks.
+
+## Possible errors
+
+* [omgx/batch-submitter](https://hub.docker.com/layers/156091606/omgx/batch-submitter/production-v1/images/sha256-b3e61c1350b94cca73853867e1267e6f0e197ffbf7661f76c5c373e85eb3e70f?context=repo)
+
+  The queued data in the `CTC-queue` contract might not match to the data of the L1 block. We have noticed the following situations:
+
+  * `The timestamp of the queued element` >` timestamp of L1 block` and `block number of the queued element` === `block number of L1 block`.
+  * `The timestamp of the queued element` >` timestamp of L1 block` and `block number of the queued element` > `block number of L1 block`.
+
+  The second issue can be fixed by enabling the [AUTO_FIX_BATCH_OPTIONS_CONF](https://github.com/omgnetwork/optimism/blob/8fd511e608744f182f8a10e6fb5aa5d27f581860/packages/batch-submitter/src/exec/run-batch-submitter.ts#L241) to `fixMonotonicity`.

+
+  `omgx/l2geth` may have the incompatible genesis when we update the deployer.
+
+  ```
+   Fatal: Error starting protocol stack: database contains incompatible genesis
+  ```
+
+  We solve it by removing the old data. However, it's not a good way to solve it. It's related to #regensis topic.
+
+## Regenesis
+
+Two possible reasons that we need to do regenesis on L2geth.
+
+1. When l2geth starts, it will fully sync with old data. If we have thousands of L2 blocks, it takes a few hours to do so.
+2. When we deploy the new deployer contracts, probably we need to do regenesis.

+# OMGX Examples
+
+- [OMGX First Steps](#omgx-first-steps)
+  * [1. To spin up a local L1/L2 system](#1-to-spin-up-a-local-l1-l2-system)
+  * [2. Chose an example, compile it, deploy it, and test it](#2-chose-an-example--compile-it--deploy-it--and-test-it)
+
+## 1. To spin up a local L1/L2 system 
+
+First, install needed modules:
+
+```bash
+$ cd optimism
+$ yarn clean
+$ yarn
+$ yarn build
+```
+
+Then, navigate to the `/ops` folder and start the system. Make sure you have the docker app running!
+
+```bash
+$ cd ops
+$ docker-compose down #only needed if you are currently running a local system
+$ docker-compose build
+$ docker-compose up -V
+```
+
+## 2. Chose an example, compile it, deploy it, and test it
+
+For example, if you would like to deploy a simple ERC20 token using hardhat, navigate to the `hardhat` folder and compile the contract:
+
+```bash
+$ cd /omgx_examples/hardhat
+$ yarn
+$ yarn compile      #compile the examples for the local L1
+$ yarn compile:ovm  #compile the examples for the local L2
+$ yarn compile:omgx #compile the examples for the OMGX Rinkeby L2
+```
+
+Now, see it all work. The `ovm` suffix denotes deploying and running contracts on the L2.
+
+```bash
+$ yarn test:integration      #test the examples on the local L1
+$ yarn test:integration:ovm  #test the examples on the local L2
+$ yarn test:integration:omgx #test the examples on the OMGX Rinkeby L2
+```
+
+To deploy the contracts to the various chains,
+
+```bash
+$ yarn deploy      #test the examples on the local L1
+$ yarn deploy:ovm  #test the examples on the local L2
+$ yarn deploy:omgx #test the examples on the OMGX Rinkeby L2
+```
+
+Note that not all commands are availible for all the different examples, and the commands will be slightly different fro `waffle` and so forth. See the `package.json` files for example-specific syntax, or the Readme.md in the examples.

+# OMGX ERC20 Example
+
+## 1. Compiling the contracts
+
+First, spin up a local system as usual (see the top-level `Readme.md`). Then, run:
+
+```bash
+$ yarn
+$ yarn compile       #for your local L1
+$ yarn compile:ovm   #for your local L2
+$ yarn compile:omgx  #for OMGX Rinkeby
+```
+
+## 2. Testing
+
+```bash
+$ yarn test:integration:ovm  #for your local L1/L2
+$ yarn test:integration:omgx #for OMGX Rinkeby
+```
+
+```bash
+% yarn test:integration:omgx
+yarn run v1.22.10
+$ hardhat test --network omgx_rinkeby
+
+
+  ERC20
+    ✓ should have a name (1395ms)
+    ✓ should have a total supply equal to the initial supply (1403ms)
+    ✓ should give the initial supply to the creator's address (1733ms)
+    transfer(...)
+      ✓ should revert when the sender does not have enough balance (1970ms)
+      ✓ should succeed when the sender has enough balance (5681ms)
+    transferFrom(...)
+      ✓ should revert when the sender does not have enough of an allowance (1974ms)
+      ✓ should succeed when the owner has enough balance and the sender has a large enough allowance (9559ms)
+
+
+  7 passing (46s)
+
+✨  Done in 48.41s.

+# OMGX L1-L2 Deposit/Withdrawal
+
+## 1. Compiling the contracts
+
+First, spin up a local system as usual (see the top-level `Readme.md`). Then, run:
+
+```bash
+$ yarn
+$ yarn compile       #for your local L1
+$ yarn compile:ovm   #for your local L2
+$ yarn compile:omgx  #for OMGX Rinkeby
+```
+
+## 2. Testing
+
+```bash
+$ yarn test:integration:ovm  #for your local L1/L2
+$ yarn test:integration:omgx #for OMGX Rinkeby
+```
+
+```bash
+% yarn test:integration:omgx
+
+L1 <> L2 Deposit and Withdrawal
+    Initialization and initial balances
+      ✓ should have initial L1 balance of 1234 and initial L2 balance of 0 (40ms)
+    L1 to L2 deposit
+      ✓ should approve 1234 tokens for ERC20 bridge (107ms)
+      ✓ should deposit 1234 tokens into L2 ERC20 (4270ms)
+      ✓ should relay deposit message to L2 (4085ms)
+      ✓ should have changed L1 balance to 0 and L2 balance to 1234
+    L2 to L1 withdrawal
+      ✓ should approve 1234 tokens for ERC20 bridge (98ms)
+      ✓ should withdraw tokens back to L1 ERC20 and relay the message (179ms)
+      ✓ should relay withdrawal message to L1 (4094ms)
+      ✓ should have changed L1 balance back to 1234 and L2 balance back to 0
+
+
+  9 passing (13s)
+
+✨  Done in 14.33s.

+
+## SUSHI
+
+SUSHI is a DeFi exchange that supports token swapping and many other actions. We started by copying SUSHI's smart contracts into the `/contracts` folder. Then, we ran:
+
+```bash
+yarn install
+yarn build
+yarn analyze
+yarn deploy
+```
+
+We then addressed the warnings and errors one by one. Let's now take that all, step by step.
+
+## 0. Basics
+
+**Your contracts.** As noted, run `yarn install` and drop your contracts into a folder called `contracts`. That's what solc and hardhat will look at, compile, and deploy. Then, run:
+
+```bash
+yarn build
+```
+
+The first time you do this, you will see dozens of errors.
+
+**Missing libraries.** The provided `package.json` is generic and you will see HH411 errors such as 
+
+```
+Error HH411: The library foo, imported from contracts/something.sol, is not installed. Try installing it using npm.
+```
+
+This means that you have to install the foo library:
+
+```bash
+yarn add foo
+```
+
+**Solidity Versions.** Once all the missing libraries have been installed, you will see `HH606` errors:
+
+```
+Error HH606: The project cannot be compiled, see reasons below.
+
+The Solidity version pragma statement in these files don't match any of the configured compilers in your config. Change the pragma or configure additional compiler versions in your hardhat config.
+
+  * contracts/something.sol (^0.6.0)
+```
+
+The optimism solc compiler supports Solidity versions 0.5.16, 0.6.12, and 0.7.6. This value is set in `hardhat.config.js`. The first time you run `yarn build` you will typically see many errors relating to your pragmas. If most of your pragmas are around 0.6 you would chose 0.6.12, and so forth. In general, small modifications (such as replacing `^0.5.17` with `^0.5.16` or specifying a broader range such as `pragma solidity >= 0.5.16 < 0.6.5;`) will not affect your code and your unit and integration tests will pick up any exceptions. 
+
+At this point, solc and hardhat have all the information they need to get started. Now, you will see actual code issues, such as: 
+
+```
+OVM Compiler Error (insert "// @unsupported: ovm" if you don't want this file to be compiled for the OVM):
+ contracts/foo.sol:72:31: ParserError: OVM: ORIGIN is not implemented in the OVM.
+        require(msg.sender == tx.origin, "not eoa");
+
+OVM Compiler Error (insert "// @unsupported: ovm" if you don't want this file to be compiled for the OVM):
+ contracts/WETH.sol:51:16: ParserError: OVM: SELFBALANCE is not implemented in the OVM. (We have no native ETH -- use deposited WETH instead!)
+        return address(this).balance;
+               ^-------------------^
+
+Error HH600: Compilation failed
+```
+
+Let's now tackle those one by one.
+
+## 1. No native ETH
+
+In many smart contracts, ETH is handled slightly differently than ERC20 tokens, but on L2, there is no native ETH. Instead, L2s use an ERC20 representation of ETH such as wETH or oETH. This means that all ETH-specific functions can be deleted, since there are no longer needed. For example:
+
+```diff
+
+contracts/uniswapv2/interfaces/IUniswapV2Router01.sol 
+@@ -16,14 +17,15 @@ interface IUniswapV2Router01 {
+	...
+-    function addLiquidityETH(
+-        address token,
+-        uint amountTokenDesired,
+-        uint amountTokenMin,
+-        uint amountETHMin,
+-        address to,
+-        uint deadline
+-    ) external payable returns (uint amountToken, uint amountETH, uint liquidity);
++    // CHANGE_OMGX
++    // function addLiquidityETH(
++    //     address token,
++    //     uint amountTokenDesired,
++    //     uint amountTokenMin,
++    //     uint amountETHMin,
++    //     address to,
++    //     uint deadline
++    // ) external payable returns (uint amountToken, uint amountETH, uint liquidity);
+
+```
+
+From a UI/Frontend perspective, 'native' ETH functions are no longer needed and integration test code will also need any ETH-specific tests to be commented out. In the case of the SUSHI port, among other changes, `contracts/mocks/WETH9Mock.sol` can be deleted entirely and many functions in `contracts/uniswapv2/UniswapV2Router02.sol` can also be deleted, such as `removeLiquidityETH` and `swapExactETHForTokens` etc. Removing functions in the contracts also affects the interfaces, of course, e.g. `contracts/uniswapv2/interfaces/IUniswapV2Router01.sol`.
+
+## 2. Timing, `now`, and `block.timestamp`
+
+The L2 does not have traditional blocks. Control over time, and manipulation of apparent time, is critical for L2, since during a fraud proof, the L1 contacts will need to replay the L2 contracts at specific times _in the past_ to check their correctness. `block.timestamp` returns the last L1 block in which a rollup batch was posted. This means that the `block.timestamp` returned on L2 can lag as many as 10 minutes behind L1. Depending on how `block.timestamp` is being used, this 1-10 min lag could have **serious unexpected implications**. See [OVM-vs-EVM-Block-Timestamps](https://hackmd.io/@scopelift/Hy853dTsP#OVM-vs-EVM-Block-Timestamps) for a more extensive discussion. Briefly, consider:
+
+1. The OVM timestamp lags behind the EVM, so it’s possible that e.g. OVM trades execute up 10 minutes after your specified deadline.  
+2. `permit` method signatures contain a deadline, and the approval must be sent before that deadline. In certain cases, the approval could take place after the deadline.  
+3. Bid and auction duration. If you are trying to run an auction with minute scale bid duration, then a 1-10 minute lag relative to L1 could throw that off completely.  
+
+## 3. Replace `chainid()` with `uint256 chainId = ___`
+
+```diff
+
+contracts/SushiToken.sol
+@@ -239,8 +241,8 @@ contract SushiToken is ERC20("SushiToken", "SUSHI"), Ownable {
+	...
+    function getChainId() internal pure returns (uint) {
+-       uint256 chainId;
++       uint256 chainId = 28; //or whatever the L2 ChainID is...
++       //assembly { chainId := chainid() }
+
+```
+
+## 4. Update Depreciated Syntax
+
+Not strictly L2 related, but updated it to help with future maintainability.
+
+```diff
+
+contracts/governance/Timelock.sol 
+-   (bool success, bytes memory returnData) = target.call.value(value)(callData);
++   (bool success, bytes memory returnData) = target.call{value:value}(callData);
+
+// The following syntax is deprecated: 
+// f.gas(...)(), f.value(...)() and (new C).value(...)().
+// Replace with:
+// f{gas: ..., value: ...}() and (new C){value: ...}(). 
+
+```
+
+## 5. No tx.origin
+
+L2 does not support `tx.origin`. This is typically a non-issue, since `tx.origin` is deprecated anyway and will be removed from L1 at some point. See [Vitalik's answer](https://ethereum.stackexchange.com/questions/196/how-do-i-make-my-dapp-serenity-proof). Secondly, only allowing txs from an EOA is considered an anti-pattern. It breaks composability, it prevents multisig wallets from using your product, and in general it's probably a hack to cover up some underlying security issues in the contracts. There is no easy/obvious one-line replacement for `tx.origin` - any attempt to try to detect the codesize or something of the calling contract would be spoofable. For Compound's use of `msg.sender == tx.origin`, as for Sushi, the best approach is to remove that restriction and make sure the contracts can safely handle calls from other contracts (which involves writing new code). For now, we just commented out the `require`.  
+
+```diff
+
+contracts/SushiMaker.sol
+    // Try to make flash-loan exploit harder to do by only allowing externally owned addresses.
+-   require(msg.sender == tx.origin, "SushiMaker: must use EOA");
++   //require(msg.sender == tx.origin, "SushiMaker: must use EOA");
+
+```
+
+## 6. TESTS RESULTS: All good EXCEPT evm_increaseTime and evm_mine
+
+All tests clear EXCEPT things related to `evm_increaseTime` and `evm_mine`. Note that this does not affect the contracts _per se_ but affects testing.

+# The Contracts Analyzer
+
+This repo is used to analyze contracts written for L1, as a starting point for evaluating potential code changes needed to deploy them to L2.
+
+## Prerequisites
+
+Please make sure you've installed:
+
+- [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
+- [Node.js](https://nodejs.org/en/download/)
+- [Yarn](https://classic.yarnpkg.com/en/docs/install#mac-stable)
+
+## Add Contracts
+
+Copy your contracts into `/contracts` and run:
+
+```bash
+yarn build #build the smart contracts with optimistic solc
+yarn analyze
+```
+
+You will probably have to `yarn add` multiple packages, and change/update pragmas, such as, to `pragma solidity 0.6.12;`
+
+## Notes
+
+The code compliles the contracts, which will typically provide extensive debug information and warnings/errors, and also checks for contract size and inline assembly.
+
+## Deploying Contracts to LOCAL L2
+
+First, make sure you have a `.env`. The five TEST_PRIVATE_KEYs are used for testing. The DEPLOYER_PRIVATE_KEY is used to deploy contracts. Since (right now) we don't charge oWETH to deploy contracts on L2, the wallets do not need any funds in them.
+
+```javascript
+L2_NODE_WEB3_URL=http://localhost:8545
+DEPLOYER_PRIVATE_KEY=0x7c852118294e51e653712a81e05800f419141751be58f605c371e15141b007a6
+TEST_PRIVATE_KEY_1=0x7c852118294e51e653712a81e05800f419141751be58f605c371e15141b007a6

+```
+
+Then, deploy:
+
+```bash
+yarn deploy
+```
+
+You should then see a list of contract addresses.
+
+## Deploying Contracts to OMGX RINKEBY
+
+Make sure you have a `.env`, and that the `L2_NODE_WEB3_URL` is set correctly. Then, set your variables similar to this:
+
+```javascript
+L2_NODE_WEB3_URL=https://rinkeby.omgx.network
+DEPLOYER_PRIVATE_KEY=0x7c852118294e51e653712a81e05800f419141751be58f605c371e15141b007a6

+```
+
+Next, comment out `{gasPrice: 0, gasLimit: 800000}` in three places - they are not needed for now:
+
+```
+GitHub/optimism/packages/omgx/contracts-analyzer/scripts/deploy.js:
+   66      // Transfer Sushi Ownership to Chef
+   67      console.log(" 🔑 Transfer Sushi Ownership to Chef")
+   68:     await (await SushiToken.transferOwnership(MasterChef.address, { gasLimit: 800000, gasPrice: 0 })).wait()
+   69    }
+   70  
+   ..
+   72      // Transfer ownership of MasterChef to Dev
+   73      console.log(" 🔑 Transfer ownership of MasterChef to Dev")
+   74:     await (await MasterChef.transferOwnership(deployAddress, { gasLimit: 800000, gasPrice: 0 })).wait()
+   75    }
+   76  
+
+GitHub/optimism/packages/omgx/contracts-analyzer/scripts/utils.js:
+   30    
+   31    const nonce = await signerProvider.getTransactionCount()
+   32:   const deployed = await contractArtifacts.deploy(...contractArgs, { nonce, ...overrides, gasPrice: 0, gasLimit: 800000 });
+   33    await deployed.deployTransaction.wait()
+   34  
+```
+
+Finally, deploy:
+
+```bash
+yarn deploy
+```
+
+You should then see a list of contract addresses.
+
+## Testing
+
+```bash
+yarn test:contracts
+```
+
+If you get `Error: insufficient funds for intrinsic transaction cost`, this means you need to explicitely set `{gasPrice: 0, gasLimit: 800000}` when you call contracts, such as in `await this.Factory__MasterChef.deploy`.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+# Uniswap V2 Area
+
+Code from [Uniswap V2](https://github.com/Uniswap/uniswap-v2-core/tree/27f6354bae6685612c182c3bc7577e61bc8717e3/contracts) with the following modifications.
+
+1. Change contract version to 0.6.12 and do the necessary patching.
+2. Add `migrator` member in `UniswapV2Factory` which can be set by `feeToSetter`.
+3. Allow `migrator` to specify the amount of `liquidity` during the first mint. Disallow first mint if migrator is set.

+# Getting Started with Optimistic Ethereum: Simple ERC20 Token Truffle Tutorial
+
+Hi there! Welcome to our Optimistic Ethereum ERC20 Truffle example! If you're interested in writing your first L2-compatible smart contract using Truffle as your smart contract testing framework, then you've come to the right place! This repo serves as an example for how go through and compile/test/deploy your contracts on both Ethereum, Optimistic Ethereum, and OMGX.
+
+Let's begin!
+
+## Prerequisites
+
+First, spin up a local L1/L2. Install needed modules:
+
+```bash
+$ cd optimism
+$ yarn clean
+$ yarn
+$ yarn build
+```
+
+Then, navigate to the `/ops` folder and start the system. Make sure you have the docker app running!
+
+```bash
+$ cd ops
+$ docker-compose down #only needed if you are currently running a local system
+$ docker-compose build
+$ docker-compose up -V
+```
+
+## Step 1: Compile your contracts for Optimistic Ethereum
+
+Compiling a contract for Optimistic Ethereum is pretty easy! First we'll need to install the [`@eth-optimism/solc`](https://www.npmjs.com/package/@eth-optimism/solc). Since we currently only support `solc` versions `0.5.16`, `0.6.12`, and `0.7.6` for Optimistic Ethereum contracts, we'll be using version `0.7.6` in this example.
+Let's add this package:
+
+```sh
+yarn add @eth-optimism/solc@0.7.6-alpha.1
+```
+
+Next, we just need to add a new `truffle-config-ovm.js` file to compile our contracts. Create `truffle-config-ovm.js` and add the following to it:
+
+```js
+const mnemonicPhrase = "candy maple cake sugar pudding cream honey rich smooth crumble sweet treat"
+const HDWalletProvider = require('@truffle/hdwallet-provider')
+
+module.exports = {
+  contracts_build_directory: './build-ovm',
+  networks: {
+    optimism: {
+      provider: function () {
+        return new HDWalletProvider({
+          mnemonic: {
+            phrase: mnemonicPhrase
+          },
+          providerOrUrl: 'http://127.0.0.1:8545'
+        })
+      },
+      network_id: 420,
+      host: '127.0.0.1',
+      port: 8545,
+      gasPrice: 0,
+    },
+    omgx_rinkeby: {
+      provider: function () {
+        return new HDWalletProvider({
+          mnemonic: {
+            phrase: mnemonicPhrase
+          },
+          providerOrUrl: 'http://rinkeby.omgx.network'
+        })
+      },
+      network_id: 28,
+      host: 'http://rinkeby.omgx.network',
+      port: 8545,
+      gasPrice: 0,
+    }
+  },
+  compilers: {
+    solc: {
+      // Add path to the optimism solc fork
+      version: "node_modules/@eth-optimism/solc",
+      settings: {
+        optimizer: {
+          enabled: true,
+          runs: 1
+        },
+      }
+    }
+  }
+}
+```
+
+Here, we specify the new custom Optimistic Ethereum compiler we just installed and the new build path for our optimistically compiled contracts. We also specify the network parameters of a local Optimistic Ethereum instance. This local instance will be set up soon, but we'll set this up in our config now so that it's easy for us later when we compile and deploy our Optimistic Ethereum contracts.
+
+And we're ready to compile! All you have to do is specify the `truffle-config-ovm.js` config in your `truffle` command, like so:
+
+```sh
+yarn truffle compile --config truffle-config-ovm.js
+```
+
+Our `truffle-config-ovm.js` config file tells Truffle that we want to use the Optimistic Ethereum solidity compiler.
+
+Yep, it's that easy. You can verify that everything went well by looking for the `build-ovm` directory that contains your new JSON files.
+
+Here, `build-ovm` signifies that the contracts contained in this directory have been compiled for the OVM, the **O**ptimistic **V**irtual **M**achine, as opposed to the Ethereum Virtual Machine. Now let's move on to testing!
+
+## Step 2: Testing your Optimistic Ethereum contracts
+
+Woot! It's finally time to test our contract on top of Optimistic Ethereum. Since the two JSON RPC provider URLs (one for your local instance Ethereum and Optimistic Ethereum) have already been specified in your Truffle config files, all we need to do next is run the test command.To do that, run:
+
+```sh
+yarn truffle test ./test/erc20.spec.js --network optimism --config truffle-config-ovm.js
+```
+
+Notice that we are using `truffle-config-ovm.js` to let `truffle` know that we want to use the `build-ovm` folder as our path to our JSON files. (Remember that these JSON files were compiled using the Optimistic Ethereum solidity compiler!)
+
+Additionally, we also specify the network we are testing on.
+In this case, we're testing our contract on `optimistic_ethereum`.
+
+You should see a set of passing tests for your ERC20 contract. If so, congrats!
+You're ready to deploy an application to Optimistic Ethereum.
+It really is that easy.
+
+## Step 3: Deploying your Optimistic Ethereum contracts
+
+Now we're going to deploy an Optimisic Ethereum contract using `truffle`. For Truffle based deployments, we're going to use Truffle's `migrate` command to run a migrations file for us that will deploy the contract we specify.
+
+First, let's create that migrations file. Create a new directory called `migrations` in the topmost path of your project and create a file within it called `1_deploy_ERC20_contract.js`.
+
+Next, within `1_deploy_ERC20_contract.js`, we're going to add the following logic:
+
+```js
+const ERC20 = artifacts.require('ERC20')
+
+module.exports = function (deployer, accounts) {
+  const tokenName = 'My Optimistic Coin'
+  const tokenSymbol = 'OPT'
+  const tokenDecimals = 1
+
+  // deployment steps
+  deployer.deploy(
+    ERC20, 
+    10000, 
+    tokenName, 
+    tokenDecimals, 
+    tokenSymbol,
+    { gasPrice: 0 }
+  )
+}
+```
+
+To quickly explain this file, first we import our artifact for our ERC20 contract.
+Since we specified the build directory in our Truffle configs, Truffle knows whether we want to use either an Ethereum or Optimistic Ethereum contract artifact.
+
+Now we're ready to run our migrations file!
+Let's go ahead and deploy this contract:
+
+```sh
+yarn truffle migrate --network optimism --config truffle-config-ovm.js #deploy on your local L2
+
+or...
+
+yarn truffle migrate --network omgx_rinkeby --config truffle-config-ovm.js #deploy on omgx Rinkeby
+```
+
+After a few seconds your contract should be deployed! Now you'll see this in your terminal:
+
+![Truffle contract migrations to Optimistic Ethereum complete](./assets/deploy-to-optimistic-ethereum.png)
+
+And uh... yeah.
+That's pretty much it.
+Contracts deployed!
+Tutorial complete. Hopefully now you know the basics of working with Optimistic Ethereum! 🅾�

+
+## Further Reading
+
+### OVM vs. EVM Incompatibilities
+
+Our goal is to bring the OVM as close to 100% compatibility with all existing Ethereum projects, but our software is still in an early stage. [Our community hub docs](https://community.optimism.io/docs/protocol/evm-comparison.html) will maintain the most up to date list of known incompatibilities between the OVM and EVM, along with our plans to fix them.
+
+### Wasn't that easy?
+
+The OVM provides a fresh new take on layer 2 development: it's _mostly_ identical to layer 1 development.
+However, there are a few differences that are worth noting, which you can read more about in our [EVM comparison documentation](https://community.optimism.io/docs/protocol/evm-comparison.html).
+No hoops, no tricks--the Ethereum you know and love, ready to scale up with L2.
+For more info on our progress and what's going on behind the scenes, you can follow us on [Twitter](https://twitter.com/optimismPBC).

+## SUSHI
+
+SUSHI is a DeFi exchange that supports token swapping and many other actions. We started by copying SUSHI's smart contracts into the `/contracts` folder. Then, we ran:
+
+```bash
+yarn install
+yarn build
+yarn analyze
+yarn deploy
+```
+
+We then addressed the warnings and errors one by one. Let's now take that all, step by step.
+
+## 0. Basics
+
+**Your contracts.** As noted, run `yarn install` and drop your contracts into a folder called `contracts`. That's what solc and hardhat will look at, compile, and deploy. Then, run:
+
+```bash
+yarn build
+```
+
+The first time you do this, you will see dozens of errors.
+
+**Missing libraries.** The provided `package.json` is generic and you will see HH411 errors such as 
+
+```
+Error HH411: The library foo, imported from contracts/something.sol, is not installed. Try installing it using npm.
+```
+
+This means that you have to install the foo library:
+
+```bash
+yarn add foo
+```
+
+**Solidity Versions.** Once all the missing libraries have been installed, you will see `HH606` errors:
+
+```
+Error HH606: The project cannot be compiled, see reasons below.
+
+The Solidity version pragma statement in these files don't match any of the configured compilers in your config. Change the pragma or configure additional compiler versions in your hardhat config.
+
+  * contracts/something.sol (^0.6.0)
+```
+
+The optimism solc compiler supports Solidity versions 0.5.16, 0.6.12, and 0.7.6. This value is set in `hardhat.config.js`. The first time you run `yarn build` you will typically see many errors relating to your pragmas. If most of your pragmas are around 0.6 you would chose 0.6.12, and so forth. In general, small modifications (such as replacing `^0.5.17` with `^0.5.16` or specifying a broader range such as `pragma solidity >= 0.5.16 < 0.6.5;`) will not affect your code and your unit and integration tests will pick up any exceptions. 
+
+At this point, solc and hardhat have all the information they need to get started. Now, you will see actual code issues, such as: 
+
+```
+OVM Compiler Error (insert "// @unsupported: ovm" if you don't want this file to be compiled for the OVM):
+ contracts/foo.sol:72:31: ParserError: OVM: ORIGIN is not implemented in the OVM.
+        require(msg.sender == tx.origin, "not eoa");
+
+OVM Compiler Error (insert "// @unsupported: ovm" if you don't want this file to be compiled for the OVM):
+ contracts/WETH.sol:51:16: ParserError: OVM: SELFBALANCE is not implemented in the OVM. (We have no native ETH -- use deposited WETH instead!)
+        return address(this).balance;
+               ^-------------------^
+
+Error HH600: Compilation failed
+```
+
+Let's now tackle those one by one.
+
+## 1. No native ETH
+
+In many smart contracts, ETH is handled slightly differently than ERC20 tokens, but on L2, there is no native ETH. Instead, L2s use an ERC20 representation of ETH such as wETH or oETH. This means that all ETH-specific functions can be deleted, since there are no longer needed. For example:
+
+```diff
+
+contracts/uniswapv2/interfaces/IUniswapV2Router01.sol 
+@@ -16,14 +17,15 @@ interface IUniswapV2Router01 {
+	...
+-    function addLiquidityETH(
+-        address token,
+-        uint amountTokenDesired,
+-        uint amountTokenMin,
+-        uint amountETHMin,
+-        address to,
+-        uint deadline
+-    ) external payable returns (uint amountToken, uint amountETH, uint liquidity);
++    // CHANGE_OMGX
++    // function addLiquidityETH(
++    //     address token,
++    //     uint amountTokenDesired,
++    //     uint amountTokenMin,
++    //     uint amountETHMin,
++    //     address to,
++    //     uint deadline
++    // ) external payable returns (uint amountToken, uint amountETH, uint liquidity);
+
+```
+
+From a UI/Frontend perspective, 'native' ETH functions are no longer needed and integration test code will also need any ETH-specific tests to be commented out. In the case of the SUSHI port, among other changes, `contracts/mocks/WETH9Mock.sol` can be deleted entirely and many functions in `contracts/uniswapv2/UniswapV2Router02.sol` can also be deleted, such as `removeLiquidityETH` and `swapExactETHForTokens` etc. Removing functions in the contracts also affects the interfaces, of course, e.g. `contracts/uniswapv2/interfaces/IUniswapV2Router01.sol`.
+
+## 2. Timing, `now`, and `block.timestamp`
+
+The L2 does not have traditional blocks. Control over time, and manipulation of apparent time, is critical for L2, since during a fraud proof, the L1 contacts will need to replay the L2 contracts at specific times _in the past_ to check their correctness. `block.timestamp` returns the last L1 block in which a rollup batch was posted. This means that the `block.timestamp` returned on L2 can lag as many as 10 minutes behind L1. Depending on how `block.timestamp` is being used, this 1-10 min lag could have **serious unexpected implications**. See [OVM-vs-EVM-Block-Timestamps](https://hackmd.io/@scopelift/Hy853dTsP#OVM-vs-EVM-Block-Timestamps) for a more extensive discussion. Briefly, consider:
+
+1. The OVM timestamp lags behind the EVM, so it’s possible that e.g. OVM trades execute up 10 minutes after your specified deadline.  
+2. `permit` method signatures contain a deadline, and the approval must be sent before that deadline. In certain cases, the approval could take place after the deadline.  
+3. Bid and auction duration. If you are trying to run an auction with minute scale bid duration, then a 1-10 minute lag relative to L1 could throw that off completely.  
+
+## 3. Replace `chainid()` with `uint256 chainId = ___`
+
+```diff
+
+contracts/SushiToken.sol
+@@ -239,8 +241,8 @@ contract SushiToken is ERC20("SushiToken", "SUSHI"), Ownable {
+	...
+    function getChainId() internal pure returns (uint) {
+-       uint256 chainId;
++       uint256 chainId = 28; //or whatever the L2 ChainID is...
++       //assembly { chainId := chainid() }
+
+```
+
+## 4. Update Depreciated Syntax
+
+Not strictly L2 related, but updated it to help with future maintainability.
+
+```diff
+
+contracts/governance/Timelock.sol 
+-   (bool success, bytes memory returnData) = target.call.value(value)(callData);
++   (bool success, bytes memory returnData) = target.call{value:value}(callData);
+
+// The following syntax is deprecated: 
+// f.gas(...)(), f.value(...)() and (new C).value(...)().
+// Replace with:
+// f{gas: ..., value: ...}() and (new C){value: ...}(). 
+
+```
+
+## 5. No tx.origin
+
+L2 does not support `tx.origin`. This is typically a non-issue, since `tx.origin` is deprecated anyway and will be removed from L1 at some point. See [Vitalik's answer](https://ethereum.stackexchange.com/questions/196/how-do-i-make-my-dapp-serenity-proof). Secondly, only allowing txs from an EOA is considered an anti-pattern. It breaks composability, it prevents multisig wallets from using your product, and in general it's probably a hack to cover up some underlying security issues in the contracts. There is no easy/obvious one-line replacement for `tx.origin` - any attempt to try to detect the codesize or something of the calling contract would be spoofable. For Compound's use of `msg.sender == tx.origin`, as for Sushi, the best approach is to remove that restriction and make sure the contracts can safely handle calls from other contracts (which involves writing new code). For now, we just commented out the `require`.  
+
+```diff
+
+contracts/SushiMaker.sol
+    // Try to make flash-loan exploit harder to do by only allowing externally owned addresses.
+-   require(msg.sender == tx.origin, "SushiMaker: must use EOA");
++   //require(msg.sender == tx.origin, "SushiMaker: must use EOA");
+
+```
+
+## 6. TESTS RESULTS: All good EXCEPT evm_increaseTime and evm_mine
+
+All tests clear EXCEPT things related to `evm_increaseTime` and `evm_mine`. Note that this does not affect the contracts _per se_ but affects testing.

+# The Contracts Analyzer
+
+This repo is used to analyze contracts written for L1, as a starting point for evaluating potential code changes needed to deploy them to L2.
+
+## Prerequisites
+
+Please make sure you've installed:
+
+- [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
+- [Node.js](https://nodejs.org/en/download/)
+- [Yarn](https://classic.yarnpkg.com/en/docs/install#mac-stable)
+
+## Setting Up
+
+Set up the project by running:
+
+```bash
+yarn install
+cd packages/omgx/contracts-analyzer
+```
+
+## Add Contracts
+
+Copy your contracts into `/contracts` and run:
+
+```bash
+yarn build #build the smart contracts with optimistic solc
+yarn analyze
+```
+
+You will probably have to `yarn add` multiple packages, and change/update pragmas, such as, to `pragma solidity 0.6.12;`
+
+## Notes
+
+The code compliles the contracts, which will typically provide extensive debug information and warnings/errors, and also checks for contract size and inline assembly. The second contract size check is superfluous, since the compiler already does that.
+
+## Deploying Contracts to LOCAL L2
+
+First, make sure you have a `.env` in `packages/omgx/contracts-analyzer`. The five TEST_PRIVATE_KEYs are used for testing. The DEPLOYER_PRIVATE_KEY is used to deploy contracts. Since (right now) we don't charge oWETH to deploy contracts on L2, the wallets do not need any funds in them.
+
+```javascript
+L2_NODE_WEB3_URL=http://localhost:8545
+DEPLOYER_PRIVATE_KEY=0x7c852118294e51e653712a81e05800f419141751be58f605c371e15141b007a6
+TEST_PRIVATE_KEY_1=0x7c852118294e51e653712a81e05800f419141751be58f605c371e15141b007a6
+TEST_PRIVATE_KEY_2=0x47e179ec197488593b187f80a00eb0da91f1b9d0b13f8733639f19c30a34926a
+TEST_PRIVATE_KEY_3=0x8b3a350cf5c34c9194ca85829a2df0ec3153be0318b5e2d3348e872092edffba
+TEST_PRIVATE_KEY_4=0x92db14e403b83dfe3df233f83dfa3a0d7096f21ca9b0d6d6b8d88b2b4ec1564e
+TEST_PRIVATE_KEY_5=0x4bbbf85ce3377467afe5d46f804f221813b2bb87f24d81f60f1fcdbf7cbf4356
+```
+
+Then, deploy:
+
+```bash
+yarn deploy
+```
+
+You should then see a list of contract addresses.
+
+## Deploying Contracts to OMGX RINKEBY
+
+Make sure you have a `.env` in `packages/omgx/contracts-analyzer`. Then, set your variables similar to this:
+
+```javascript
+L2_NODE_WEB3_URL=https://rinkeby.omgx.network
+DEPLOYER_PRIVATE_KEY=0x7c852118294e51e653712a81e05800f419141751be58f605c371e15141b007a6
+TEST_PRIVATE_KEY_1=0x7c852118294e51e653712a81e05800f419141751be58f605c371e15141b007a6
+TEST_PRIVATE_KEY_2=0x47e179ec197488593b187f80a00eb0da91f1b9d0b13f8733639f19c30a34926a
+TEST_PRIVATE_KEY_3=0x8b3a350cf5c34c9194ca85829a2df0ec3153be0318b5e2d3348e872092edffba
+TEST_PRIVATE_KEY_4=0x92db14e403b83dfe3df233f83dfa3a0d7096f21ca9b0d6d6b8d88b2b4ec1564e
+TEST_PRIVATE_KEY_5=0x4bbbf85ce3377467afe5d46f804f221813b2bb87f24d81f60f1fcdbf7cbf4356
+```
+
+Next, comment out `{gasPrice: 0, gasLimit: 800000}` in three places - they are not needed for now:
+
+```
+GitHub/optimism/packages/omgx/contracts-analyzer/scripts/deploy.js:
+   66      // Transfer Sushi Ownership to Chef
+   67      console.log(" 🔑 Transfer Sushi Ownership to Chef")
+   68:     await (await SushiToken.transferOwnership(MasterChef.address, { gasLimit: 800000, gasPrice: 0 })).wait()
+   69    }
+   70  
+   ..
+   72      // Transfer ownership of MasterChef to Dev
+   73      console.log(" 🔑 Transfer ownership of MasterChef to Dev")
+   74:     await (await MasterChef.transferOwnership(deployAddress, { gasLimit: 800000, gasPrice: 0 })).wait()
+   75    }
+   76  
+
+GitHub/optimism/packages/omgx/contracts-analyzer/scripts/utils.js:
+   30    
+   31    const nonce = await signerProvider.getTransactionCount()
+   32:   const deployed = await contractArtifacts.deploy(...contractArgs, { nonce, ...overrides, gasPrice: 0, gasLimit: 800000 });
+   33    await deployed.deployTransaction.wait()
+   34  
+```
+
+Finally, deploy:
+
+```bash
+yarn deploy
+```
+
+You should then see a list of contract addresses.
+
+## Testing
+
+```bash
+yarn test:contracts
+```
+
+If you get `Error: insufficient funds for intrinsic transaction cost`, this means you need to explicitely set `{gasPrice: 0, gasLimit: 800000}` when you call contracts, such as in `await this.Factory__MasterChef.deploy`.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+# Uniswap V2 Area
+
+Code from [Uniswap V2](https://github.com/Uniswap/uniswap-v2-core/tree/27f6354bae6685612c182c3bc7577e61bc8717e3/contracts) with the following modifications.
+
+1. Change contract version to 0.6.12 and do the necessary patching.
+2. Add `migrator` member in `UniswapV2Factory` which can be set by `feeToSetter`.
+3. Allow `migrator` to specify the amount of `liquidity` during the first mint. Disallow first mint if migrator is set.

+# Fraud Prover
+
+Contains an executable fraud prover. This repo allows you to:
+
+1. Generate a fraud prover Docker
+2. Run that docker and the associated L2 in Verifier mode, pointed at a local OMGX.
+3. Inject fraudulant state roots to debug the currently non-operational fraud-prover.
+
+## 1. FIRST TERMINAL WINDOW: Building & Running a local system with Verifier and Fraud Prover
+
+Make sure dependencies are installed and everything is built - just run `yarn` and `yarn build` in the top directory  (/optimsm). Then spin up the entire system with the L2, the Verifier, and the Fraud Prover:
+
+```bash
+
+./up_local.sh #to spin up and verify a local OMGX
+
+```
+
+At this point you will have the *L1*, *L2*, the *Verifier*, the *data_transport_layer*, the *batch_submitter*, *the *message_relayer*, the *deployer*, and the *fraud_prover* all running and talking to one another. So far so good. 
+
+## 2. SECOND TERMINAL WINDOW: Injecting Fraudulant State Roots
+
+The `docker-compose-local.env.yaml` sets:
+
+```bash
+
+#this is the address that will trigger the batch_submitter to inject fake state roots
+x-var: &FRAUD_SUBMISSION_ADDRESS
+  FRAUD_SUBMISSION_ADDRESS=0xb0dd88dfcc929a78fec13daa1bd77843e267c729
+
+```
+
+Any transactions fron this wallet will cause the `batch_submitter` to submit a bad state root (`0xbad1bad1......`) instead of the correct state root. Normnally, the batch submitter only does this once, but we patched the batch submitter to allow many fraudulant transaction to be submitted. **Open a second terminal** and then:
+
+```bash
+
+yarn build:fraud
+yarn deploy 
+
+```
+
+You will see a few contracts get deployed, and you will see *Mr. Fraud* transferring some funds to Alice. Running `yarn deploy` **does** trigger the batch submitter to inject a bad state root, but then, the system reverts, proably due to indexing and other issues. Note that hardhat needs a `.env` for the deploy - see the `example.env` for working settings.
+
+```bash
+#expected terminal output

+ On L2, Bob now has: BigNumber { _hex: '0x0821ab0d4414980000', _isBigNumber: true }
+    ✓ Bob Approve and Deposit ERC20 from L1 to L2 (5233ms)
+    ✓ should transfer ERC20 token to Alice and Fraud (4166ms)

+ On L2, Fraud now has: 12000000000000000000
+    ✓ should transfer ERC20 token from Fraud to Bob and commit fraud (4123ms)
+
+```
+
+## 3. THIRD TERMINAL WINDOW: Running a local Fraud Prover for rapid debugging purposes
+
+First, *terminate the dockerized fraud-prover service* and then `yarn build` and `yarn start` a fraud-prover from your command line - this makes it much easier and faster to debug, since you get better debug and console.log output, and its easier to make code changes and see what happens. This fraud-prover will also use whatever you set in the .env (which should match of couse with what all the dockerized services are getting from the `docker-compose-local.env.yaml`)
+
+```bash
+
+yarn build
+yarn start
+
+```
+
+## CURRENTLY BROKEN AT One of three places - Lib_MerkleTree.sol, OVM_FraudVerifier.sol, or "makeStateTrie for this proof"
+
+If you do all of the above, while using the standard contracts, you will get stuck at *EITHER*:
+
+```bash
+# this is in Lib_MerkleTree.sol
+
+require(
+  _siblings.length == _ceilLog2(_totalLeaves),
+  "Lib_MerkleTree: Total siblings does not correctly correspond to total leaves."
+);
+
+```
+
+*OR* you will get through that but then revert at `VM Exception while processing transaction: revert Pre-state root global index must equal to the transaction root global index`:
+
+```bash
+# this is in OVM_FraudVerifier.sol
+
+line 134
+
+require (
+    _preStateRootBatchHeader.prevTotalElements + _preStateRootProof.index + 1 == _transactionBatchHeader.prevTotalElements + _transactionProof.index,
+    "Pre-state root global index must equal to the transaction root global index."
+);
+
+```
+
+*OR* you will get stuck at `_makeStateTrie for this proof`. There are also assorted and sundy other ways for this to fail, mostly relating to out of bounds access to various arrays, most notably, in the transactions.
+
+## 4. Generating the Fraud Prover Docker 
+
+To build the Docker:
+
+```bash
+
+docker build . --file Dockerfile.fraud-prover --tag omgx/fraud-prover:latest
+docker push omgx/fraud-prover:latest
+
+```
+
+## NOT UPDATED 5. Configuration
+
+All configuration is done via environment variables. See below for more information.
+
+## NOT UPDATED 6. Testing & linting
+
+- See lint errors with `yarn lint`; auto-fix with `yarn lint --fix`
+
+## NOT UPDATED 7. Envs (Need to reconcile with the below - ToDo)
+
+| Environment Variable   | Required? | Default Value         | Description            |
+| -----------            | --------- | -------------         | -----------           |
+| `L1_WALLET_KEY`        | Yes       | N/A                   | Private key for an account on Layer 1 (Ethereum) to be used to submit fraud proof transactions. |
+| `L2_NODE_WEB3_URL`     | No        | http://localhost:9545 | HTTP endpoint for a Layer 2 (Optimism) Verifier node.  |
+| `L1_NODE_WEB3_URL`     | No        | http://localhost:8545 | HTTP endpoint for a Layer 1 (Ethereum) node.      |
+| `RELAY_GAS_LIMIT`      | No        | 9,000,000             | Maximum amount of gas to provide to fraud proof transactions (except for the "transaction execution" step). |
+| `RUN_GAS_LIMIT`        | No        | 9,000,000             | Maximum amount of gas to provide to the "transaction execution" step. |
+| `POLLING_INTERVAL`     | No        | 5,000                 | Time (in milliseconds) to wait while polling for new transactions. |
+| `L2_BLOCK_OFFSET`      | No        | 1                     | Offset between the `CanonicalTransactionChain` contract on Layer 1 and the blocks on Layer 2. Currently defaults to 1, but will likely be removed as soon as possible. |
+| `L1_BLOCK_FINALITY`    | No        | 0                     | Number of Layer 1 blocks to wait before considering a given event. |
+| `L1_START_OFFSET`      | No        | 0                     | Layer 1 block number to start scanning for transactions from. |
+| `FROM_L2_TRANSACTION_INDEX` | No        | 0                     | Layer 2 block number to start scanning for transactions from. |
+
+## NOT UPDATED 8. Local testing
+
+The fraud prover will first connect to the relevant chains and then look for mismatched state roots. Note that the *Fraud Prover* does not connect to the *Sequencer*, rather, it connects to the *Verifier*, and the Verifier in turn is looking at the L1. Assuming _your sequencer is not fraudulant_, the standard Fraud Prover output looks like this:
+
+```
+
+{"level":30,"time":1619122304289,"msg":"Looking for mismatched state roots..."}
+{"level":30,"time":1619122304295,"nextAttemptInS":5,"msg":"Did not find any mismatched state roots"}
+{"level":30,"time":1619122309301,"msg":"Looking for mismatched state roots..."}
+{"level":30,"time":1619122309306,"nextAttemptInS":5,"msg":"Did not find any mismatched state roots"}
+{"level":30,"time":1619122314311,"msg":"Looking for mismatched state roots..."}
+
+```
+
+When you spin up your local test system some small changes to the generic `local.env.yaml` and `local.yaml` may be needed. Also, you will have to provide two extra files, `wait-for-l1-and-l2.sh`. For your testing conveniance, there is also a `Dockerfile.fraud_prover`.
+
+### local.yaml Settings
+
+Add to your `local.yaml`
+```bash
+#all the usual things here (L2, Batch submitter, Message Relay, Hardhat, Deployer), but then...
+

+# omgx_optimism2aws
+
+Directory hosting different devops automations, cloudformation templates and other
+AWS related resources for deploying omgx_optimism integration to AWS ECS
+
+## How to use the automation hosted here?
+
+1. Make the code changes for each of the services you need in the monorepo, they're located in the packages directory, one level up from this README.md file
+
+2. Make sure you've got your secrets already imported in AWS, either by adding them manually or by using the `aws-secrets-importer.py` script hosted in this repository. The `aws-secrets-importer.py` can be used the following way, which would read a particular yaml file and import the secrets from it in AWS Secret Manager.
+
+Here is an example of how to run the `aws-secrets-importer.py`:
+
+```
+$ ./aws-secrets-importer.py -i docker-compose-local.env.yml -d secret-foo -n secret-foo -r us-east-1 -p default
+{
+    "ARN": "arn:aws:secretsmanager:us-east-1:942431445534:secret:secret-foo-lAl7Pu",
+    "Name": "secret-foo",
+    "VersionId": "5848d972-98ba-4b97-8b0c-e04db2560613"
+}
+```
+
+3. Make sure you have installed [jq](https://stedolan.github.io/jq/) and configured [awscli](https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2.html)
+
+
+## Deployment: how to use the key cfn-devenv.sh script
+
+Use the `cfn-devenv.sh` to provision, update, destroy or reset your own development environment using AWS ECS
+
+* Before provisioning the services, make sure their containers exist, choose a tag from which to pull from hub.docker.com and push to AWS ECR. The example below will pull all services with tag `latest` from the omgx hub.docker.com and push to AWS the
+same container, but with the tag would be `aws-latest`. So if your original tag is `foo`, then the final tag will be `aws-foo`.
+
+```
+./cfn-devenv.sh push2aws --region us-east-1 --deploy-tag aws-latest --from-tag latest --registry-prefix omgx
+```
+
+To generate new AWS container for only one service, you can specifiy the service name and then execute:
+
+```
+./cfn-devenv.sh push2aws --region us-east-1 --deploy-tag aws-latest --from-tag latest --registry-prefix omgx --service-name deployer
+```
+
+* Once we're sure all the containers have been pushed to AWS, we can provision the whole stack with:
+
+```
+./cfn-devenv.sh create --stack-name test-stack --region us-east-1 --deploy-tag aws-latest
+./cfn-devenv.sh deploy --stack-name test-stack --region us-east-1 --deploy-tag aws-latest --registry-prefix omgx --secret-name aws-secret-name
+```
+
+* To update, for example, the batch-submitter, which is already running, you could:
+
+```
+./cfn-devenv.sh update --stack-name test-stack --region us-east-1 --deploy-tag aws-latest --registry-prefix omgx --secret-name aws-secret-name --service-name batch-submitter
+```
+
+* If you don't specify `--service-name` - all services are going to be updated
+
+* If you don't specify `--secret-name` - the `--deploy-tag` will become `--secret-name`
+
+* To add a new service to the stack, you should add the respective cloudformation template in the `cloudformation` directory,
+then add a folder named like the cloudformation template to the `docker` directory, then execute `push2aws`, and then execute `deploy`.
+
+* To login to the server via ssh:
+```
+./cfn-devenv.sh ssh --stack-name test-stack --region us-east-1
+
+Starting session with SessionId: petar@enya.ai-0bbe0cdbc42865625
+sh-4.2$ sudo su
+[root@ip-10-0-2-250 bin]# docker ps
+```
+
+* To restart all services in a cluster, simply use the command below, it will pull all latest containers with the same tag and re-read the AWS Secrets again, then run all the containers:
+```
+./cfn-devenv.sh restart --stack-name test-stack
+```
+
+* To restart all services in a cluster and remove the contents in the /mnt/efs directory, you can run:
+```
+./cfn-devenv.sh restart --stack-name test-stack --force
+```
+
+* To stop all services in a cluster, you can run:
+```
+./cfn-devenv.sh stop --stack-name test-stack
+```
+
+* To stop all services in a cluster and remove the contents in the /mnt/efs directory, you can run:
+```
+./cfn-devenv.sh stop --stack-name test-stack --force
+```
+
+* To see all current ECS clusters provisioned with this automation, run:
+```
+./cfn-devenv.sh list-clusters

+Simple Bash automation allowing for deployment, updating, destruction of a development environment. The script automatically checks the AWS Elastic Container Registry whether the `DEPLOY_TAG` already exists. If not - images are generated and pushed to the ECR.
+
+The script also outputs the Cloudwatch Log Groups of each of the services, making it easy to monitor the log stream with [saw](https://github.com/TylerBrock/saw) or some other `cloudwatch tail -f` tool.
+
+An example from the cfn-devenv.sh help:
+
+```

+
+When we start the deployer service, it exposes two files. One is `addresses.json`, which returns the above addresses. Another one is `state-dump.latest.json`, which is the **abi** and address of the above contracts. Other services load `state-dump.latest.json` and use the **abi** to interact with these contracts.
+
+> Deployer starts before all other services. 
+
+> We should comment out the deploying code **packages/contracts/bin/deploy.ts** when we build the image for Rinkeby env. Otherwise, it will redeploy some contracts when the deployer service starts.
+
+> It uses `DEPLOYER_PRIVATE_KEY` to deploy contracts. SCC and CTC only allow certain accounts to submit the data. These accounts are defined in **packages/contracts/bin/deploy.ts**. **SCC** only allows **ovmProposerAddress** to submit data and **CTC** only allows **ovmSequencerAddress** to push data.
+>
+> We use different accounts for **ovmSequencerAddress**, **ovmProposerAddress**, **ovmRelayerAddress** and **ovmAddressManagerOwner**.
+
+## Batch Submitter
+
+It submits the TX batch and state batch to contracts deployed by the deployer. The TX is submitted to `OVM_CanonicalTransactionChain` and the state batch is submitted to `OVM_StateCommitmentChain`. For any message that is sent between L1 and L2, the batch submitter submits TX batch first, then submits the state batch next.
+
+We use two different accounts (**ovmSequencerAddress** and **ovmProposerAddress** ) to submit tx and state batch, respectively.
+
+## Message relayer
+
+The message relayer relays the message that is sent from the L2 contract to the L1 contract. The message relayer fetches the batches from `OVM_StateCommitmentChain`, then it gets the original message from L2 according to the block number of the batches. If L1 contracts use the standard **OVM_CrossDomainEnabled**, the message that is sent from the L2 contract to the L1 contract has a 7-days proof window. Once it passes 7 days, the message relayer will relay the message.
+
+> How is the message sent from L2 to L1?
+>
+> The L2 and L1 contracts need to import **OVM_CrossDomainEnabled** to enable the communication between L1 and L2. L2 contracts send the message by using:
+>
+> ```
+> bytes memory data = abi.encodeWithSelector(
+>     L1Contract.L1ContractFunction.selector,
+>     L1ContractFunctionVariable_1,
+>     L1ContractFunctionVariable_2,
+>     L1ContractFunctionVariable_3
+> );
+> 
+> // Send calldata into L1
+> sendCrossDomainMessage(
+>     address(L1ContractAddress),
+>     data, // message that the message relayer is going to relay
+>     getFinalizeDepositL1Gas() 
+> );
+> ```
+
+> The message relayer doesn't relay the message again if the relaying transaction has the nonce error. Therefore, we have to use different accounts for the **message-relayer service** and **message-relayer-fast service**.
+
+## Message Relayer Fast
+
+The message that is relayed by the **message-relayer service** has a 7-days proof window time. Therefore, we create the **message-relayer-fast** to bypass the proof window time. Using the **message-relayer-fast** requires the L1 contract to import the **OVM_FastCrossDomainEnabled**. The fast message relayer fetches the batches from `OVM_StateCommitmentChain` , just like the standard message relayer, but we add the whitelist system to restrict the messages that can be relayed to L1. Only messages that  target certain L1 contracts can be relayed by **message-relayer-fast service**. 
+
+Since **message-relayer service** can get the messages that are supposed to be relayed by **message-relayer-fast service**, we add the blacklist system. The standard message relayer doesn't relay messages that target certain L1 contracts. It saves us gas.
+
+# Understand Log
+
+When we start the integration or production services, the most important test is sending the message between L1 and L2. Normally, the message can be easily sent from L1 to L2 if the batch submitter works correctly. Thus, I focus on how to debug the system when the message can't be sent from L2 to L1.
+
+## Debugging steps
+
+1. Make sure all services connect to the right **SCC** and **CTC**. The addressManagerAddresses of all services are the same.
+
+   * Batch submitter
+
+     ```javascript
+     Configured batch submitter address: {addressManagerAddress:  0x0787a989eDDeb40a64BBEAB94F2fF30CEb70A184}
+     Initialed new CTC: 0xa833AAF1888d257b08F634F3c6FBc751Ce1A4815
+     ```
+
+   * Message relayer and message relayer fast
+
+     ```javascript
+     Connecting to OVM_StateCommitmentChain...
+     Connected to OVM_StateCommitmentChain: 0xE5B5814Ca76FEA28d9c389cbf86CaDEfC5f25c20
+     Connecting to OVM_L1CrossDomainMessenger...
+     Connected to OVM_L1CrossDomainMessenger: 0xaD05Bc932DA6f15a30976C533d309944c18C3b57
+     // Message relayer and message relayer fast connect to two differnt OVM_L1CrossDomainMessangers.
+     ```
+
+2. When the test is running, check the log of the batch submitter first. Successfully submitting the batches should have the following log:
+
+   ```javascript
+   // Submit the tx batch first
+   Submitted appendSequencerBatch transaction: {txHash: , from: }
+   appendSequencerBatch transaction data: {data: }
+   Submitted batch!
+   // Submit the state root batch next
+   Submitted appendStateBatch transaction: {txHash: from: }
+   appendStateBatch transaction data: {data: }
+   Submitted state root batch!
+   ```
+
+3. After the batch submitter submits the data, please check the log of the message relayer or message relayer fast according to the transaction type. Both message relayers should find a batch of the finalized transaction(s). The log of successfully relaying the message is
+
+   ```
+   Found a batch of finalized transaction(s), checking for more...
+   Found finalized transactions
+   Found a message sent during transaction
+   Message not yet relayed. Attempting to generate a proof...
+   Successfully generated a proof. Attempting to relay to Layer 1...
+   Relay message transaction sent
+   Relay message included in block
+   Message successfully relayed to Layer 1!
+   ```

+
+    Use this tool to create an EnyaLabs Optimism Integration Environment
+    based on a given DeployTag.
+
+    Basic usage is to evoke the script with a sub-command and options for
+    that sub-command.
+
+    Global options:
+
+        [--region <region>]             AWS region (us-east-1, eu-west-1, us-west-1, etc) [default: us-east-1]
+        -h, --help                      This help :)
+
+    Subcommands:
+
+        create                          create an environment, e.g. provision VPC, ECS Cluster and then deploy the containers
+            --deploy-tag <deploy-tag>           The Git Tag or Branch Name of all of the services
+            --stack-name <stack-name>                       Stack Name to create
+
+        restart                         does restart of a particular service in a cluster, useful when you've pushed new docker container with the old tag,
+                                        as it will be pulled again, also, if you've changed some variable in the aws secrets - it will re-read them again
+            --stack-name <stack-name>       the name of the stack, in which you want to restart the service
+            --service-name <service-name>   the actual service name
+
+        update                          update an environment, e.g. update the containers to certain deploy-tag
+            --deploy-tag <deploy-tag>           The Git Tag or Branch Name of all of the services
+            --service-name <service-name>       The name of the service you want to update, if not specified - all services are deployed with the <deploy-tag>
+            --secret-name <secret-name>         The name of the secret to be used for rebuilding the container, if not specified - the deploy tag is being taken as secret name

+
+        deploy                          deploy to an environment, e.g. perform a deployment, for example, you've removed one service OR would like to add new to your dev env
+            --deploy-tag <deploy-tag>           The Git Tag or Branch Name of all of the services
+            --service-name <service-name>       The name of the service you want to update, if not specified - all services are deployed with the <deploy-tag>

+## Description
+Script'll subscribe l1 and l2. Every new block, callback'll get balance of l1 pool and l2 pool, then log to console. Datadog agent can collect logs from docker host.
+
+## How to setup monitoring
+1. Create .env follow example:
+    ```
+    NODE_ENV=rinkeby
+    L1_NODE_WEB3_WS=ws://localhost:9545
+    L2_NODE_WEB3_WS=ws://localhost:8546
+    L1_LIQUIDITY_POOL_ADDRESS=0x1383fF5A0Ef67f4BE949408838478917d87FeAc7
+    L2_LIQUIDITY_POOL_ADDRESS=0x88b3743A9e1FdB3C8C92Cec7A6A370c1403c7C60
+    RELAYER_ADDRESS=0x3C8b7FdbF1e5B2519B00A8c9317C4BA51d6a4f9d
+    SEQUENCER_ADDRESS=0xE50faB5E5F46BB3E3e412d6DFbA73491a2D97695
+    RECONNECT_TIME=10000 // delay time to reconect provider
+    ```
+2. run `npm start`
+
+## How to setup dummy-transaction
+1. Create .env follow example:
+    ```
+    NODE_ENV=rinkeby
+    L1_NODE_WEB3_URL=https://rinkeby.infura.io/v3/d64a23da1a714a0f9f8bf6c9352235a8
+    L2_NODE_WEB3_URL=http://ec2-54-226-193-17.compute-1.amazonaws.com:8545
+    L1_LIQUIDITY_POOL_ADDRESS=0x473d2bbF979D0BFA39EBAB320c3216408386e68d
+    L2_LIQUIDITY_POOL_ADDRESS=0x1eCD5FBbb64F375A74670A1233CfA74D695fD861
+    L1_GAS_USED=229932
+    L1_ADDRESS_MANAGER=0x93A96D6A5beb1F661cf052722A1424CDDA3e9418
+    L2_DEPOSITED_ERC20=0x0e52DEfc53ec6dCc52d630af949a9b6313455aDF
+    DUMMY_DELAY_MINS=5
+    DUMMY_ETH_AMOUNT=0.0005
+        ```
+2. run `npm run dummy-transaction`
+
+## How to deploy image
+1. Build new image: `docker build -t enyalabs/omgx-monitor:{version-number} .` version-number:
+    - format `v1.1.2` is for monitoring service
+    - format `dummy-v1.1.2` is for dummy-transaction service
+2. Push new image to docker hub: `docker push enyalabs/omgx-monitor:{version-number}`

+# secret2env
+
+`secret2env` is a simple program that retrieves a secret from AWS
+secrets manager, parses the secret value as a json and exports the secret
+into multiple environment variables
+
+
+## Build
+
+`Makefile` is provided; Run `make` and it will build the program
+on the current platform and output a file in the current directory
+
+## Example
+
+We have a secret that hosts a lot of environment variables in aws region
+`us-east-1`
+
+Running `secret2env --name foo --region us-east-1` will output the
+following text:
+
+```
+export variable1=1
+export variable2=2
+export variable3=3
+```
+
+If you wish to export the variables into the current environment, you
+need to do `eval $(./secret2env -name foo -region us-east-1)` in the
+shell.
+
+In case of an error, the program will return an exit value of 1 and
+fail silently so as not to break downstream output processing).

+## Observability in production
+
+When deploying Batch Submitter to production / a live ETH network, populate the environment variables `NODE_ENV` (`development`, `production`, or `test`) and `ETH_NETWORK_NAME` (`mainnet`, `kovan`, `goerli`). This enables Batch Submitter to capture more context in logs and metrics, and initializes [Sentry](https://docs.sentry.io/platforms/node/) to track errors.

+### Deploying the Contracts
+To deploy the contracts first clone, install, and build the contracts package.
+
+Next set the following env vars:
+
+```bash
+CONTRACTS_TARGET_NETWORK=...
+CONTRACTS_DEPLOYER_KEY=...
+CONTRACTS_RPC_URL=...
+```
+
+Then to perform the actual deployment run:
+
+```bash
+npx hardhat deploy \

+  --ovm-sequencer-address ... \
+  --scc-fraud-proof-window ... \

An operation is considered unsafe if it would access state variables which are specific to the environment (ie. L1 or L2) in which it is executed, as this could be used to \"escape the sandbox\" of the OVM, resulting in non-deterministic fraud proofs. That is, an attacker would be able to \"prove fraud\" on an honestly applied transaction. Note that a \"safe\" contract requires opcodes to appear in a particular pattern; omission of \"unsafe\" opcodes is necessary, but not sufficient. Compiler used: solc Runtime target: EVM",

Note for future developers: do NOT make anything in this contract 'public' unless you know what you're doing. Anything public can potentially have a function signature that conflicts with a signature attached to the implementation contract. Public functions SHOULD always have the 'proxyCallIfNotOwner' modifier unless there's some *really* good reason not to have that modifier. And there almost certainly is not a good reason to not have that modifier. Beware!",

Canonical Transaction Chain (CTC) contract is an append-only log of transactions which must be applied to the rollup state. It defines the ordering of rollup transactions by writing them to the 'CTC:batches' instance of the Chain Storage Container.

2.\\n * The EM's run() function is the first function called during the execution of any\\n * transaction on L2.\\n * For each context-dependent EVM operation the EM has a function which implements a corresponding\\n * OVM operation, which will read state from the State Manager contract.\\n * The EM relies on the Safety Checker to verify that code deployed to Layer 2 does not contain any\\n * context-dependent operations.\\n *\\n * Compiler used: solc\\n * Runtime target: EVM\\n */\\ncontract OVM_ExecutionManager is iOVM_ExecutionManager, Lib_AddressResolver {\\n\\n

The CTC also allows any account to 'enqueue' an L2 transaction, which will require that the Sequencer will eventually append it to the rollup state. If the Sequencer does not include an enqueued transaction within the 'force inclusion period', then any account may force it to be included by calling appendQueueBatch().

The {initializer} modifier provided by this contract will have this effect.\\n *\\n * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\\n * possible by providing the encoded function call as the `_data` argument to {UpgradeableProxy-constructor}.\\n *\\n * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\\n * that all initializers are idempotent.

Very close to being a normal proxy but has added functions `setCode` and `setStorage` for changing the code or storage of the contract. Nifty! Note for future developers: do NOT make anything in this contract 'public' unless you know what you're doing. Anything public can potentially have a function signature that conflicts with a signature attached to the implementation contract.

Anything public can potentially have a function signature that conflicts with a signature attached to the implementation contract. Public functions SHOULD always have the 'proxyCallIfNotOwner' modifier unless there's some *really* good reason not to have that modifier. And there almost certainly is not a good reason to not have that modifier. Beware!",

Canonical Transaction Chain (CTC) contract is an append-only log of transactions which must be applied to the rollup state. It defines the ordering of rollup transactions by writing them to the 'CTC:batches' instance of the Chain Storage Container.

2.\\n * The EM's run() function is the first function called during the execution of any\\n * transaction on L2.\\n * For each context-dependent EVM operation the EM has a function which implements a corresponding\\n * OVM operation, which will read state from the State Manager contract.\\n * The EM relies on the Safety Checker to verify that code deployed to Layer 2 does not contain any\\n * context-dependent operations.\\n *\\n * Compiler used: solc\\n * Runtime target: EVM\\n */\\ncontract OVM_ExecutionManager is iOVM_ExecutionManager, Lib_AddressResolver {\\n\\n

The CTC also allows any account to 'enqueue' an L2 transaction, which will require that the Sequencer will eventually append it to the rollup state. If the Sequencer does not include an enqueued transaction within the 'force inclusion period', then any account may force it to be included by calling appendQueueBatch().

The {initializer} modifier provided by this contract will have this effect.\\n *\\n * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\\n * possible by providing the encoded function call as the `_data` argument to {UpgradeableProxy-constructor}.\\n *\\n * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\\n * that all initializers are idempotent.

An operation is considered unsafe if it would access state variables which are specific to the environment (ie.

Very close to being a normal proxy but has added functions `setCode` and `setStorage` for changing the code or storage of the contract. Nifty! Note for future developers: do NOT make anything in this contract 'public' unless you know what you're doing. Anything public can potentially have a function signature that conflicts with a signature attached to the implementation contract.

Anything public can potentially have a function signature that conflicts with a signature attached to the implementation contract. Public functions SHOULD always have the 'proxyCallIfNotOwner' modifier unless there's some *really* good reason not to have that modifier. And there almost certainly is not a good reason to not have that modifier. Beware!",

An operation is considered unsafe if it would access state variables which are specific to the environment (ie. L1 or L2) in which it is executed, as this could be used to \"escape the sandbox\" of the OVM, resulting in non-deterministic fraud proofs. That is, an attacker would be able to \"prove fraud\" on an honestly applied transaction. Note that a \"safe\" contract requires opcodes to appear in a particular pattern; omission of \"unsafe\" opcodes is necessary, but not sufficient. Compiler used: solc Runtime target: EVM",

Anything public can potentially have a function signature that conflicts with a signature attached to the implementation contract. Public functions SHOULD always have the 'proxyCallIfNotOwner' modifier unless there's some *really* good reason not to have that modifier. And there almost certainly is not a good reason to not have that modifier. Beware!",

An operation is considered unsafe if it would access state variables which are specific to the environment (ie. L1 or L2) in which it is executed, as this could be used to \"escape the sandbox\" of the OVM, resulting in non-deterministic fraud proofs. That is, an attacker would be able to \"prove fraud\" on an honestly applied transaction. Note that a \"safe\" contract requires opcodes to appear in a particular pattern; omission of \"unsafe\" opcodes is necessary, but not sufficient. Compiler used: solc Runtime target: EVM",

Anything public can potentially have a function signature that conflicts with a signature attached to the implementation contract. Public functions SHOULD always have the 'proxyCallIfNotOwner' modifier unless there's some *really* good reason not to have that modifier. And there almost certainly is not a good reason to not have that modifier. Beware!",

+# @eth-optimism/message-relayer
+
+This package contains:
+
+1. A service for relaying messages from L2 to L1.
+2. Utilities for finding these messages and relaying them.
+
+## Installation
+
+```
+yarn add @eth-optimism/message-relayer
+```
+
+## Relay Utilities
+
+### getMessagesAndProofsForL2Transaction
+
+Finds all L2 => L1 messages sent in a given L2 transaction and generates proof for each.
+
+#### Usage
+
+```typescript
+import { getMessagesAndProofsForL2Transaction } from '@eth-optimism/message-relayer'
+
+const main = async () => {
+  const l1RpcProviderUrl = 'https://layer1.endpoint'
+  const l2RpcProviderUrl = 'https://layer2.endpoint'
+  const l1StateCommitmentChainAddress = 'address of OVM_StateCommitmentChain from deployments page'
+  const l2CrossDomainMessengerAddress = 'address of OVM_L2CrossDomainMessenger from deployments page'
+  const l2TransactionHash = 'hash of the transaction with messages to relay'
+
+  const messagePairs = await getMessagesAndProofsForL2Transaction(
+    l1RpcProviderUrl,
+    l2RpcProviderUrl,
+    l1StateCommitmentChainAddress,
+    l2CrossDomainMessengerAddress,
+    l2TransactionHash
+  )
+
+  console.log(messagePairs)
+  // Will log something along the lines of:
+  // [
+  //   {
+  //     message: {
+  //       target: '0x...',
+  //       sender: '0x...',
+  //       message: '0x...',
+  //       messageNonce: 1234...
+  //     },
+  //     proof: {
+  //       // complicated
+  //     }
+  //   }
+  // ]
+
+  // You can then do something along the lines of:
+  // for (const { message, proof } of messagePairs) {
+  //   await l1CrossDomainMessenger.relayMessage(
+  //     message.target,
+  //     message.sender,
+  //     message.message,
+  //     message.messageNonce,
+  //     proof
+  //   )
+  // }
+} 
+
+main()
+```

+# OMGX Smart Contracts
+
+
+## 1. Automatic contract deployment and serving
+
+This spins up the entire stack, with all contracts deployed, and all the right things needed for the wallet to function, and for development work on the wallet.
+
+```bash
+
+$ cd ops 
+$ ./up_local.sh
+
+```
+
+**Note - please provide syntax for setting the .env variables (BUILD: 1, DAEMON: 1)**
+
+To get the contract addresses for the basic stack, and the OMGX-specific contracts:
+
+```bash
+
+curl http://127.0.0.1:8078/addresses.json | jq #basic stack
+curl http://127.0.0.1:8080/addresses.json | jq #OMGX-specific contracts
+
+```
+
+## 2. Manual Deployment and Testing
+
+Spin up the base local L1/L2:
+
+```
+
+$ cd ops
+$ docker-compose up -V
+
+```
+
+Create a `.env` file in the root directory of the contracts folder. Add environment-specific variables on new lines in the form of `NAME=VALUE`. Examples are given in the `.env.example` file. Just pick which net you want to work on and copy either the "Rinkeby" _or_ the "Local" envs to your `.env`.
+
+```bash
+
+# Local
+NODE_ENV=local
+L1_NODE_WEB3_URL=http://localhost:9545
+L2_NODE_WEB3_URL=http://localhost:8545

+TARGET_GAS_LIMIT=9000000000
+CHAIN_ID=28
+TEST=1 #This deploys the ERC20 test token
+
+```
+
+Build and deploy all the needed contracts:
+
+```bash
+
+$ yarn build
+$ yarn deploy
+
+```
+
+You will now see this, if everything worked correctly:
+
+```bash
+
+ % yarn deploy
+yarn run v1.22.10
+$ ts-node "./bin/deploy.ts"

+
+The L2 liquidity pool is the main pool. It provides a way to deposit and withdraw tokens for liquidity providers. Swap users can deposit ETH or ERC20 tokens to fastly exit the L2.
+
+The L1 liquidity pool is the sub pool. Swap users can do fast onramp. When swap users do a fast exit via the L2 liquidity pool, it sends funds to the swap users.
+
+For OMGX, there are no delays for users to move funds from L1 to L2. The liquidity pool is used to help users quickly exit L2.

+# API for OMG Network Vault Plugin
+
+The API is authenticated, so every client must possess a valid Vault token that has permissions for the operation being requested. The plugin must be mounted at a particular path - the actual path is a design choice. For the sake of this documentation, the path will be `immutability-eth-plugin`. Mounting the plugin must be done by the administrator. Follows is an example of how a plugin is mounted assuming that the plugin is in the `$HOME/etc/vault.d/vault_plugins/` folder:
+
+```sh
+export SHA256=$(shasum -a 256 "$HOME/etc/vault.d/vault_plugins/immutability-eth-plugin" | cut -d' ' -f1)
+vault write sys/plugins/catalog/secret/immutability-eth-plugin \
+      sha_256="${SHA256}" \
+      command="immutability-eth-plugin --ca-cert=$HOME/etc/vault.d/root.crt --client-cert=$HOME/etc/vault.d/vault.crt --client-key=$HOME/etc/vault.d/vault.key"
+vault secrets enable -path=immutability-eth-plugin -plugin-name=immutability-eth-plugin plugin
+
+```
+
+In the examples, it is assumed that the Vault address is `http://127.0.0.1:8900`. This aligns with the Docker-based smoke testing scripts. Thus, for the subsequent API documentation, you will see the URL `http://127.0.0.1:8900/v1/immutability-eth-plugin/` used. This is what the URL is when the plugin is being tested via the Docker-based smoke testing scripts. It should be clear that this URL will vary based on how Vault is configured in your environment.
+
+## CONFIGURATION
+
+Before a plugin can be used, it must be configured. This is where we establish the RPC endpoint for the Ethereum node. This can be an Infura endpoint. Also, the chain ID must be supplied.
+
+### CONFIGURE MOUNT
+
+A PUT to the `/config` path is used configure the mount.
+
+#### INPUTS
+
+| Parameter | Description |
+| --- | ----------- |
+| chain_id | Ethereum network. Default = 4 (Rinkeby) |
+| rpc_url | The RPC address of the Ethereum network. Default = `https://rinkeby.infura.io` |
+| whitelist | The list of accounts that any account can send ETH to. |
+| blacklist | The list of accounts that any account can't send ETH to. |
+| bound_cidr_list | Comma separated string or list of CIDR blocks. If set, specifies the blocks of IPs which are allowed to use the plugin. |
+
+#### EXAMPLE
+
+The following `curl` command will configure the mount to use Ganache as the Ethereum node.
+
+```sh
+
+curl -X PUT -H "X-Vault-Token: $(vault print token)" -H "X-Vault-Request: true" -d '{"chain_id":"5777","rpc_url":"http://ganache:8545"}' http://127.0.0.1:8900/v1/immutability-eth-plugin/config
+
+{
+  "request_id": "0f6dcfcd-905b-cb27-9ff2-242722395645",
+  "lease_id": "",
+  "lease_duration": 0,
+  "renewable": false,
+  "data": {
+    "blacklist": null,
+    "bound_cidr_list": null,
+    "chain_id": "5777",
+    "rpc_url": "http://ganache:8545",
+    "whitelist": null
+  },
+  "warnings": null
+}
+```
+
+### READ MOUNT CONFIGURATION
+
+The following `curl` command will read the mount configuration.
+
+```sh
+curl -H "X-Vault-Token: $(vault print token)" -H "X-Vault-Request: true" http://127.0.0.1:8900/v1/immutability-eth-plugin/config
+
+{
+  "request_id": "b35dd8f3-1d3b-11a9-a723-dc892720efb7",
+  "lease_id": "",
+  "lease_duration": 0,
+  "renewable": false,
+  "data": {
+    "blacklist": null,
+    "bound_cidr_list": null,
+    "chain_id": "5777",
+    "rpc_url": "http://ganache:8545",
+    "chain_l2_id": "28",
+    "rpc_l2_url": "http://l2geth:9545",
+    "whitelist": null
+  },
+  "warnings": null
+}
+
+```
+
+## WALLETS
+
+A wallet contains the BIP44 key used to derive accounts.
+
+### CREATE WALLET
+
+A PUT to the `/wallets/<NAME>` enpoint creates (or updates) an Ethereum wallet: an wallet controlled by a private key. Also The generator produces a high-entropy passphrase.
+
+### INPUTS
+
+| Parameter | Description |
+| --- | ----------- |
+| name | Name of the wallet - provided in the URI. |
+| mnemonic | The mnemonic to use to create the account. If not provided, one is generated. |

+| blacklist | The list of Ethereum accounts that accounts in this wallet can't send transactions to. |
+
+### EXAMPLE
+
+The following `curl` command will create a wallet named `test-wallet-1`.
+
+```sh
+curl -X PUT -H "X-Vault-Request: true" -H "X-Vault-Token: $(vault print token)" -d 'null' http://127.0.0.1:8900/v1/immutability-eth-plugin/wallets/test-wallet-1

+# immutability-eth-plugin docker
+
+Previously, when you executed `docker-compose -f docker/docker-compose.yml up --build` it would:
+
+* Spin up a ganache container
+* Deploy the plasma contracts
+* Spin up an `ephemeral` vault instance
+* Execute some smoke tests
+
+Now, the behavior is different.
+
+The first time you bring up the `docker-compose`, it will:
+
+* Spin up a ganache container
+* Deploy the plasma contracts
+* Spin up a `persistent` vault instance
+* Initialize the vault instance - with one key shard
+* Unseal the vault instance
+* Execute some smoke tests
+
+From then on, however, all subsequent runs of `docker-compose` will:
+
+* Spin up a ganache container
+* Deploy the plasma contracts
+* Spin up a `persistent` vault instance
+* Unseal the vault instance
+
+If you interact with vault from the outside - say change the rpc_url, create new accounts, etc - all that will be persisted. so, each subsequent time you run docker-compose, your previous interactions will be retained.
+
+### How to interact with Vault from the outside
+
+If this project is in `$GOPATH/src/github.com/omgnetwork/immutability-eth-plugin`, then the persisted vault data is located in 3 places:
+
+1. TLS Certificates and Key: `$GOPATH/src/github.com/omgnetwork/immutability-eth-plugin/docker/config/ca`
+
+You will need to trust the signer to use the vault CLI:
+
+```bash
+export VAULT_CACERT="$GOPATH/src/github.com/omgnetwork/immutability-eth-plugin/docker/config/ca.crt"
+```
+
+2. Unseal Key and Root Token: `$GOPATH/src/github.com/omgnetwork/immutability-eth-plugin/docker/config/unseal.json`
+
+You will need to use the root token (or another token derived from it) to test:
+
+```bash
+export VAULT_TOKEN=$(cat $GOPATH/src/github.com/omgnetwork/immutability-eth-plugin/docker/config/unseal.json | jq -r .root_token)
+```
+
+3. The Vault data store: `$GOPATH/src/github.com/omgnetwork/immutability-eth-plugin/docker/config/data`
+
+Don't mess with this.
+
+If you want to re-initialize the Vault, then delete these:
+
+```bash
+rm $GOPATH/src/github.com/omgnetwork/immutability-eth-plugin/config/docker/unseal.json
+rm -fr $GOPATH/src/github.com/omgnetwork/immutability-eth-plugin/docker/config/data
+```
+
+I would strongly advise using the Vault CLI. This way you can use vault with the same semantics that you see in the smoke tests:
+
+```bash
+export VAULT_ADDR="https://127.0.0.1:8200"
+export VAULT_CACERT="$GOPATH/src/github.com/omgnetwork/immutability-eth-plugin/docker/config/ca.crt"
+export VAULT_TOKEN=$(cat $GOPATH/src/github.com/omgnetwork/immutability-eth-plugin/docker/config/unseal.json | jq -r .root_token)
+
+vault read -format=json immutability-eth-plugin/config
+
+``` 
+
+Unless of course, you are using elixir... in which case, you are on your own.

+*********************************
+Cluster Architecture
+*********************************
+
+Immutability's model for private key management for Ethereum is dependent upon the customer's risk tolerance. Specifically, the risk of a loss of availability is balanced against the risk of unauthorized access to private key material. In either case, security of private keys is of utmost importance. Follows is a set of pictures that describes an approach that balances these 2 dimensions (availability and security).
+
+This new design attempts to provide the best mix of availability and security with a minimum of operational encumbrance.
+
+Security Overview
+####################
+
+The important points to be aware of from a security standpoint are:
+
+1. The Plasma Authority: The private key used to sign `submitBlock` transactions is generated inside a crypto-barrier and never leaves that barrier. Access to signing operations using this private key are controlled by Vault access controls.
+
+2. Client Service Accounts: The OmiseGo client applications will have to authenticate to Vault with a Kubernetes service account to sign transactions using the Plasma Authority's private key. If any rogue client is able to assume the role of this Kubernetes service account, it will be able to sign transactions using the Plasma Authority's private key.
+
+3. IP Constraints: IP whitelisting is available to further protect access to signing operations using the Plasma Authority's private key.
+
+4. Shamir Key Sharing: The master encryption key that Vault uses to encrypt all data is constructed using Shamir key sharing. The key shards are PGP encrypted and kept offline. 
+
+5. Unsealer Vault: The process to unseal Vault nodes is automated via an ephemeral unsealer Vault. This can be implemented as an air-gapped laptop that is temprorarily brought online during upgrade events or after container scheduling events.
+
+6. Vault Node Service Accounts: The Vault nodes (which maintain the Authority's private key) have to authenticate to the Unsealer Vault with a Kubernetes service account to unseal themselves. These service accounts will only be used during unseal operations (during those brief moments that the Unsealer Vault is online.)
+
+Create Unsealer Vault
+#################################
+
+The first, and heaviest, bit of operational workflow involves the creation of the unsealer Vault. For the purposes of this discussion, we will implement this with a laptop. On an air-gapped laptop, we initialize Vault using the PGP identities of 5 OmiseGo parties. The PGP encrypted keyshards are stored safely off-line. The data that comprises the initialization state of these keyshards is backed up. The Unsealer Vault is configured to allow a specific Kubernetes service account (see #6 above) to have access to encrypt and decrypt the unseal key used to form the master encryption key for the main Vault nodes.
+
+This laptop is kept offline most of the time and is stored in a secure location.

+Initial Deployment
+#################################
+
+During the initial deployment of Vault, the laptop that is the Unsealer Vault is turned on (while still air-gapped) and it is itself unsealed. This is turtle 0. Once unsealed, and with all remnants of the decrypted keyshards removed from memory, the laptop is attached to the VPN and given a well-known address (IP or DNS.)
+
+Then, the Kubernetes admin deploys the Vault cluster (a load balancer and 3 or more Vault nodes.) These Vault nodes will reach out to the Unsealer Vault to unseal themselves; but, since this is the initial deployment, that will fail since this newly deployed Vault cluster has not been initialized yet.
+
+Then an operator on the Unsealer Vault will initialize this newly deployed cluster, saving the PGP encrypted recovery keys in much the same way that the initial PGP keyshards were saved. This initialization process will create a root token that is then used to configure the Vault cluster. The data for this Vault cluster (i.e., the Authority's private key) is snapshotted and backed up. This snapshot should be tested prior to using the Authority's address.

+
+Ready for Business
+#################################
+
+After the Vault cluster was initialized, all nodes unsealed themselves and joined the cluster. The Vault nodes are ready to take traffic now. The OmiseGo clients are able to submit blocks now.

+  :alt: Ready for Business
+
+Upgrade (or Scheduling Event)
+#################################
+
+When an upgrade is needed or if there has been a scheduling event for a Vault node, we need to engage the Unsealer Vault again. This time will be simpler since the Vault cluster has already been initialized. We bring the Unsealer Vault online in the same fashion as before. If this is an upgrade event, then the next step is for the Kubernetes admin to perform a Rolling Update by patching the deployment with a new Vault container image. The new Vault nodes will auto-unseal themselves and join the cluster. Testing can validate that the new nodes are ready.
+
+If a scheduling event was detected, then simply bring the Unsealer Vault online for a brief period of time should bring the re-scheduled nodes back into the cluster.

+*********************************
+Deployment Architecture
+*********************************
+
+Immutability's recommendation for Vault deployments is based on a number of factors which we will discuss in this section of the documentation.
+
+Regardless of a client's risk tolerance we always recommend that Vault run in a separately provisioned and cordoned off network.  Using a walled garden approach with Vault significantly increases security and makes audits simpler as you only need be concerned with Vault, allowed traffic to Vault, and any monitoring solution.  This reduces the probability that mistakes will be made when doing things like opening ports, installing libraries, etc.
+
+Note that the diagrams throughout this document will show a single instantiation of a Vault cluster deployment.  It is expected there will be multiple instantiations for dev/stage/prod/etc.
+
+The Network
+#################################
+
+Our general recommendation is that Vault run in its own network with the only allowed traffic being ingress over a layer-4 load balancer.  Egress is allowed for certain operations but is tightly controlled.  Depending upon the requirements, risk tolerance of the client, and other factors we may recommend using or not using a cloud provider.
+
+Base Network
+*****************************
+
+We show below what the base network should look like.  Access is allowed from same-level environments and some other trusted network which will be used for deployments.
+
+Note that below it is assumed that only same-level environments are connected.  For example, only prod environments should be linked from prod OmiseGO GCP projects to the Vault GCP prod project.
+
+In the case of GCP, we recommend a private network (VPC) be used with a VPN gateway and tunnels for access from external networks.  Note the image below assumes that Vault runs in GKE however running on virtual instances is similar.
+
+.. image:: _static/omisego-arch-network.png
+  :width: 1200
+  :alt: Base GCP Network
+
+There will most likely need to be 3 VPN gateways.  2 for GCP->GCP HA and 1 for administration:
+
+https://cloud.google.com/vpn/docs/how-to/choosing-a-vpn
+
+https://cloud.google.com/vpn/docs/how-to/creating-ha-vpn2
+
+Ingress/Egress on GKE
+*****************************
+
+Generally speaking no ingress should be allowed except over a private load balancer and between nodes in the vault pod and control plane (master).  Egress should be tightly locked down.  Defaults are bad.
+
+At a high level we need to:
+
+1.  Create a VPC and subnets for a GKE cluster with private access
+
+2.  Lock down VPC with firewall rules
+
+      - block egress to 0.0.0.0/0
+      - allow ingress from Google health checks
+      - allow egress to Google health checks, restricted APIs, and GKE private master CIDRs.
+
+3.  Remove default route automatically created in VPC (0.0.0.0/0 with default internet gateway as next hop).
+
+4.  Create route to reach Google restricted APIs (199.36.153.4/30) through a default internet gateway
+
+5.  Make the Cloud DNS changes and attach the zones to the VPC:
+
+      - Create private DNS zone googleapis.com with a CNAME record to restricted.googleapis.com for '*'.googleapis.com and A record to 199.36.153.4/30 for restricted.googleapis.com
+      - Create private DNS zone gcr.io with a CNAME record to gcr.io for '*'.gcr.io and A record to 199.36.153.4/30 for a blank gcr.io DNS name
+
+A high level overview of creating a private GKE cluster is here:
+
+https://cloud.google.com/kubernetes-engine/docs/how-to/private-clusters
+
+Similar changes will need to be made if running on virtual instances instead of GKE.
+
+Storage
+#################################
+
+The OmiseGo use case is unique in several regards, but mostly due to the simplicity of the data model:
+
+Based on the current Plasma design, Vault will only store 1 private key: that of the Authority. This has the potential to drastically simplify several aspects of the storage model. 2 storage options will be discussed: Raft Integrated Storage (beta) and Consul.
+
+From an I/O perspective, the Vault data store will be write-once/read-many. That is, once the private key has been generated, it will never be written again. This means that the storage medium will only be read from while active: each time a SubmitBlock transaction needs to be signed, the private key will be read (and decrypted) from storage.
+
+Backup and Recovery
+*****************************
+
+Since the Vault data model is essentially static, the data can be snapshotted at a point prior to Vault taking traffic and stored securely offline. In the case of disaster, this backup can be used to restore the state of Vault (the Authority private key, the authentication mechanism and policy configurations) very straightforwardly with low MTTR (30-60 minutes depending on the availability of the key shard holders.)
+
+Failover
+*****************************
+
+Since the Vault data is static, there is no need for replication. Therefore, it is possible to have independent (yet identical) hot (or warm) Vault clusters in multiple regions. After the first cluster was initialized, all subsequent clusters would be brought online from the snapshot. 
+
+Security
+*****************************
+
+HashiCorp has clearly documented the Vault threat model: https://www.vaultproject.io/docs/internals/security.html. Vault encrypts data in transit and data at rest, so the primary concern with regard to the security of the storage is availability: can malicious actors delete or corrupt the data? Of secondary concern is the ability of a malicious actor to use brute force to decrypt the data if they are able to capture a snapshot.
+
+With regard to the second concern, we advise a memory-based implementation of the storage model. This will make it more difficult for a malicious actor to gain access to the encrypted storage. With regard to the first concern, the recommendation is to minimize the surface area of the storage - limit access to only Vault agents.
+
+Options
+*****************************
+
+Given the simplicity of the data model - effectively 1 key-value - the reduction of complexity of the storage mechanism should increase security without increasing the risk of loss of availability. That said, we still need a highly available storage mechanism to allow new (or rescheduled) Vault nodes to sync with the current data store.
+
+**NOTE** All Vault data is encrypted at rest using Vault's master encryption key. Additional encryption may be applied at the storage layer; however, this is not essential. 
+
+The storage backends used by Vault are also untrusted by design. Vault uses a security barrier for all requests made to the backend. The security barrier automatically encrypts all data leaving Vault using a 256-bit Advanced Encryption Standard (AES) cipher in the Galois Counter Mode (GCM) with 96-bit nonces. The nonce is randomly generated for every encrypted object. When data is read from the security barrier the GCM authentication tag is verified during the decryption process to detect any tampering.
+
+Depending on the backend used, Vault may communicate with the backend over TLS to provide an added layer of security. In some cases, such as a file backend this is not applicable. Because storage backends are untrusted, an eavesdropper would only gain access to encrypted data even if communication with the backend was intercepted.
+
+Given the desire to use a memory-based storage mechanism, we recommend using one of the 2 following options:
+
+Consul Cluster
+*****************************
+
+HashiCorp Consul's key-value store can be used as a highly available storage backend for Vault. Since Consul uses a memory-based mechanism for persisting key-values, this has the security benefit that data does not reside on a disk. 
+
+Consul is a very reliable storage mechanism and supported by HashiCorp as the *official* storage backend for Vault. That said, Consul is non-trivial to manage and operate in a secure manner - https://www.consul.io/docs/internals/security.html#secure-configuration. Consul can be deployed as a StatefulSet in Kubernetes - https://www.consul.io/docs/platform/k8s/run.html. The official HashiCorp Consule Helm chart (https://www.consul.io/docs/platform/k8s/helm.html) is the recommended way to install and configure Consul on Kubernetes.
+
+.. image:: _static/new-5.png
+  :width: 1200
+  :alt: Consul Cluster
+
+Consul has the benefit of having been used successfully in conjunction with Vault for many years. However, the complexity of maintaining, securing monitoring and operating are not insignificant. The typical Consul installation for Vault is a 5 node cluster. This cluster needs access controls and network configuration. The Vault node needs a separate agent running to connect to this cluster. These agents provide a slew of features including support for the remote execution of commands (not default - but possibly misconfigured - behavior.) All of this amounts to a lot of surface area that needs to be accounted for.
+
+Raft Storage Backend (beta)
+*****************************
+
+The Raft storage backend is used to persist Vault's data. Unlike other storage backends, Raft storage does not operate from a single source of data. Instead all the nodes in a Vault cluster will have a replicated copy of Vault's data. Data gets replicated across the all the nodes via the Raft Consensus Algorithm.
+
+The Raft storage backend is currently in beta status. It is planned to be officially released in 1Q2020 with Vault 1.4. Raft can be configured to support a tmpfs file system - a tmpfs mount is temporary, and only persisted in the host memory - this would prevent data from being persisted. Since the only thing that will be stored in Vault are a private key (Authority), a few policies, and some mount configurations, the storage requirements are minimal.
+
+.. image:: _static/new-6.png
+  :width: 1200
+  :alt: Integrated Storage with Raft
+
+In Kubernetes, there are 2 approaches that are viable: 
+
+1. RAM-based `emptyDir`. The default size of a RAM-based `emptyDir` is half the RAM of the node it runs on. 
+
+2. As a Kubernetes `secret`. Kubelet stores the secret into a tmpfs so that the secret is not written to disk storage. Once the Pod that depends on the secret is deleted, kubelet will delete its local copy of the secret data as well. 
+
+The Raft storage backend requires no agents and requires no additional cluster to manage, operate and secure. This drastically reduces the attack surface of the storage model. As with all software, beta or otherwise, it is probable that bugs will exist. The simplicity of the data model allows for quick patching and upgrade. 
+
+Furthermore, the `operator migrate` command allows the Vault operator to migrate from one storage mechanism to another if so desired. A possible option is to go live with the Raft mechanism and then migrate to Consul if necessary.
+
+Audit
+#################################
+
+The best practice, with regard to auditing, when running Vault on GKE is to leverage Stackdriver. This is done by enabling file-based auditing and `vault audit enable file file_path=stdout` and by giving the service account that Vault uses `roles/logging.logWriter` permissions.
+
+Vault audit logs do not contain any sensitive information - all tokens and secrets are HMAC-ed for obfuscation. Auditing must be monitored for availability. This should be accomplished through alerting based on the following metrics:
+
+`vault.audit.log_request_failure`: This is a particularly important metric. Any non-zero value here indicates that there was a failure to make an audit log request to any of the configured audit log devices; when Vault cannot log to any of the configured audit log devices it ceases all user operations, and you should begin troubleshooting the audit log devices immediately if this metric continually increases.
+
+`vault.audit.log_response_failure`: This is a particularly important metric. Any non-zero value here indicates that there was a failure to receive a response to a request made to one of the configured audit log devices; when Vault cannot log to any of the configured audit log devices it ceases all user operations, and you should begin troubleshooting the audit log devices immediately if this metric continually increases.
+
+Telemetry
+#################################
+
+DataDog can be used to monitor important events in the Vault lifecycle - especially leader election events and restarts (transitions from unsealed to sealed.) 
+
+Vault needs to be configured with the address (https://docs.datadoghq.com/agent/kubernetes/dogstatsd/#pass-the-node-s-ip-address-to-your-application) of the DogStatD agent (https://docs.datadoghq.com/developers/dogstatsd) and any additional tags desired. These settings are documented here: https://www.vaultproject.io/docs/configuration/telemetry.html#dogstatsd
+
+Vault emits many metrics. Of special note here are the metrics related to Vault leader election and seal status:
+
+`vault.core.leadership_setup_failed`: Signals on cluster leadership setup failures which have occurred in a highly available Vault cluster. This should be monitored and alerted on for overall cluster leadership status.
+
+`vault.core.leadership_lost`: Signals cluster leadership losses which have occurred in a highly available Vault cluster. This should be monitored and alerted on for overall cluster leadership status.
+
+`vault.core.step_down`: Signals cluster leadership step downs. This should be monitored and alerted on for overall cluster leadership status.
+
+Additionally, runtime metrics should be monitored for the overall health of the system: https://www.vaultproject.io/docs/internals/telemetry.html#runtime-metrics

+Vault Design Q&A
+*********************************
+
+Here we will discuss and capture requirements for the Vault cluster architecture and plugin design.
+
+Plugin Design and Implementation
+#################################
+
+Authority discussion
+*****************************
+
+I'd like to discuss the workflow for establishing an Authority. A possible workflow is:
+
+Vault administrator creates the Authority wallet:
+::
+
+	vault write -f immutability-eth-plugin/wallets/authority
+
+Vault administrator creates an Authority account - this will be the account that is used to identify the Authority.
+
+::
+
+	AUTHORITY_ACCOUNT=$(vault write -f -field=address immutability-eth-plugin/wallets/authority/accounts)
+
+Maintainer sets authority using out-of-band contract call with $AUTHORITY_ACCOUNT
+
+After Authority is set, then the following API can be used to submit blocks:
+
+::
+
+	vault write immutability-eth-plugin/wallets/authority/accounts/$AUTHORITY_ACCOUNT/submitBlock block_number=$BLOCK_NUMBER
+
+
+Vault Cluster Design
+#################################
+
+
+Topology
+*****************************
+
+* What is your preferred deployment?
+
+   * GKE
+
+* Do you have any multi-region or HA/DR requirements?
+
+    * Currently storage is held in block storage on GCP.  Can't move horizontally, single region.
+    * After first launch will move to postgres and will have multi-region.
+    * Design will focus on a single region with information on how to move to multi-region.
+    * Multi-region will most likely be hot-warm.
+
+* What about load balancers and whitelisting of public and/or private Endpoints?  Our recommendation is to only allow internal access to the Vault cluster.
+
+    * No external access is fine.  VPN preferred.
+    * We need to include the VPN in the design.  VPN would only allow access to a single other (prod mainnet) cluster.
+
+* How highly available should it be?  We recommend running in 3 zones generally.
+
+   * 2 or 3.
+
+* How many environments will you run?
+
+    * multiple dev, one staging, and one production
+
+* Do you have a preferred storage backend for Vault?  We recommend GCS: https://www.vaultproject.io/docs/configuration/storage/google-cloud-storage.html
+
+    * Preference is Consul since it is memory based.  Perhaps raft will be a good fit here since it will provide similar features with less overhead.
+
+Security
+*****************************
+
+* How do you currently handle user access in GCP?
+
+    * Historically very little access.  Has changed recently.  Prod access only 4 people have access.
+    * Vault cluster - new google project.  Access is restricted to a few laptops that are locked away.
+    * Using google apps.
+
+* How do you provision certificates today? How will we get certificates for Vault in the pipeline?
+
+    * Edge - cloudflare.  Origin letsencrypt.
+
+* How will users access the Vault cluster?  Should we implement OIDC or is some other authn/z used?
+
+    * Users will need to be able to import/export key material.
+    * k8s service accounts for vault application/api access.
+    * We'll drill into policy in another meeting.
+    * Today RBAC in k8s, google login for IAM.
+
+* How important is security?  For example:
+
+    * Do you want us to CIS harden everything?
+
+        * Yes
+
+    * Do you want us to do penetration testing?
+
+        * We'll talk w/ OM security on this.
+
+* Unsealing
+
+    * Leaning towards manual.  Will talk to Kasima to get a business decision.
+
+* Certificates
+
+    * LE for now.  This may change.  Means < 90 day rolling updates
+
+* Access to Vault from apps
+
+    * Initially GCP service accounts
+
+
+Administration & Maintenance
+*****************************
+
+* What are your SLA requirements?  For example, can your applications tolerate an outage of a few seconds when deploying?
+
+    * None today.  Currently can handle outage of a few seconds.
+
+* How often will the cluster, vault, and plugin be updated?
+
+    * regular sec updates - ~ 1/month
+
+Other Details
+*****************************
+
+* How many transactions per second should Vault handle?
+
+    * 1/second at most.  Throttled by ethereum mainnet.
+
+* How do you handle logging/log storage?
+
+    * Use datadog for logs and log storage.
+
+* What about monitoring?  You mentioned you would like to explore Prometheus instead of DataDog?
+
+    * Datadog for initial design.  Include some prometheus discussion/details.
+
+* What is your backup strategy?
+
+    * We'll discuss offline and will discuss with security in a subsequent meeting.
+
+* Do you have any requirements for config-as-code?   For example: Terraform/Ansible/Chef/Salt/bash?
+
+    * Terraform and Helm.

+# Testing K8S Integration
+
+**NOTE:** For the purpose of development, this runs Minikube as a
+Kubernetes environment. If you already have a running Kubernetes environment  in a cloud, you can use that instead.
+
+We use an environment variable, $DEVDIR, to point to the Immutability-OmiseGo repo. For example:
+
+```sh
+$ export DEVDIR=/Users/immutability/omisego-dev
+$ la $DEVDIR/docker/ca/certs
+total 24
+-rwxrwxrwx@ 1 immutability  staff   1.2K Nov 14 15:38 ca.crt
+-rwxrwxrwx@ 1 immutability  staff    41B Nov 14 15:38 ca.srl
+-rwxrwxrwx@ 1 immutability  staff   1.3K Nov 14 15:38 my-service.crt
+```
+
+## Prerequisites
+
+You need:
+
+- [Minikube installed](https://kubernetes.io/docs/tasks/tools/install-minikube/)
+- Make sure that Minikube has been started: `minikube start`. (It is assumed that you are using hyperkit for the VM.)
+- Run Vault + OmiseGo Ethereum Plugin (`cd $DEVDIR && make run`)
+
+## As a K8S Admin [Create K8S service account](./create-service-account.sh)
+
+This service account will be used to gain access to the Authority account to submit blocks. *Care must be taken with access to this service account.*
+
+```sh
+$ ./create-service-account.sh
+serviceaccount/omisego-service created
+clusterrolebinding.rbac.authorization.k8s.io/role-tokenreview-binding configured
+```
+
+## As a Vault admin [Provision Access to Authority Account](./provision-access.sh)
+
+We will create a policy that allows the OmiseGo service account to submit blocks, then enable and configure the K8S authentication method. 
+
+**NOTE:** Configuration of the kubernetes authentication backend requires access to the credentials for the service account:
+
+```sh
+export VAULT_SA_NAME=$(kubectl get sa omisego-service -o jsonpath="{.secrets[*]['name']}")
+
+export SA_JWT_TOKEN=$(kubectl get secret $VAULT_SA_NAME -o jsonpath="{.data.token}" | base64 --decode; echo)
+```
+
+It is assumed that the Vault admin and K8S admin have similar trust profiles within the firm. Access to the K8S service account credentials *can* give access to submit blocks. The `omisego/immutability-eth-plugin` does have the ability to whitelist client IPs which would prevent access from unauthorized environments. Ideally, the actors which have legitimate access to the service account would be in a restricted subnet and disable remote access.
+
+```sh
+$ ./provision-access.sh
+path "immutability-eth-plugin/wallets/plasma-deployer/accounts/0x4BC91c7fA64017a94007B7452B75888cD82185F7/plasma/submitBlock" {
+    capabilities = ["update", "create"]
+}
+Success! Uploaded policy: submit-blocks
+Success! Enabled kubernetes auth method at: kubernetes/
+Success! Data written to: auth/kubernetes/config
+Success! Data written to: auth/kubernetes/role/authority
+```
+
+## As a K8S Admin [Configure Vault Agent](./configmaps.sh)
+
+```sh
+$ ./configmaps.sh
+configmap/cacerts created
+configmap/vault-agent-config created
+```
+
+## As a K8S Admin [Deploy Vault Agent](./deploy-agent.sh)
+
+If you are using hyperkit for your VM, your host address should be: `192.168.64.1`. However, you can always run this command from your host to determine the actual host address:
+
+```sh
+$ minikube ssh "route -n | grep ^0.0.0.0 | awk '{ print \$2 }'"
+192.168.64.1
+```
+
+If your host is different than what is shown above, you will need to edit [the K8S deployment config](k8s-agent-spec.yml) to provide a different setting for:
+
+```yaml
+      env:
+        - name: VAULT_ADDR
+          value: https://192.168.64.1:8200
+```
+
+**ALSO** if your host IP is different, you will have to [regenerate your certs](../../docker/config/gencerts.sh) with an IP SANS for that host:
+
+```
+# Alternative names are specified as IP.# and DNS.# for IPs and
+# DNS accordingly.
+[alt_names]
+IP.1  = 127.0.0.1
+IP.2  = 192.168.64.1
+IP.3  = 192.168.122.1
+DNS.1 = localhost
+
+```
+
+Deploy the vault-agent as a **normal** container. When you deploy it as a sidecar, you would deploy it as an `initContainers`. However, we want to get a shell to this container to demonstrate block submission.
+
+```sh
+$ ./deploy-agent.sh
+pod/omisego-agent-sidecar created
+```
+
+Now, we get shell on the vault agent:
+
+```sh
+$ kubectl exec -it omisego-agent-sidecar --container vault-agent-auth sh
+/ # export VAULT_TOKEN=$(cat /vault/.vault-token)
+/ # export VAULT_CACERT=/certs/vault-cacert
+/ # vault  write immutability-eth-plugin/wallets/plasma-deployer/accounts/0x4BC91c7fA64017a94007B7452B75888cD82185F7/plasma/submitBlock block_root=1234qweradgf1234qweradgf contract=0xd185aff7fb18d2045ba766287ca64992fdd79b1e

+# GCP and Vault Infrastructure
+
+This directory holds the Terraform scripts and the Helm chart overrides to deploy the cloud infrastructure and Kubernetes resources into two Google Cloud projects.
+
+## GCloud Authentication
+
+You have to authenticate with the `gcloud` command line tool (download if not already installed). If you already have credentials locally for the project, you can simply set `GOOGLE_APPLICATION_CREDENTIALS` to the local file path, and Terraform will utilize those credentials.
+
+Otherwise, you can run `gcloud init` to create a fresh GCP project configuration locally, or just run:
+
+```bash
+$ gcloud auth login
+$ gcloud config set project $PROJECT_ID # <-- important for subsequent commands
+```
+
+This will open up a browser window for you to login and authorize access to the target project for `gcloud` to provider credentials for. This session with `gcloud` can later be revoked by running:
+
+```bash
+$ gcloud auth revoke
+```
+
+> Note:
+> 
+> Alternatively, if you have a service account designated for IaC deployments, you can activate those credentials with:
+> ```bash
+> $ gcloud auth activate-service-account --key-file <path_to_key_file>
+> ```
+
+## Terraform
+
+[Source](./terraform)
+
+The Terraform scripts in this directory are used for standing up the cloud infrastructure in Google Cloud necessary for running and connecting to the Vault cluster deployed the GKE.
+
+### Resources
+
+- [VPC](./terraform/vpc.tf)
+- [Firewall Rules](./terraform/firewall.tf)
+  - Allows:
+    - VPC peering for client connections
+    - Datadog egress for telemetry
+    - Infura egress for Ethereum API connection
+- [Container Registry](./terraform/gcr.tf)
+  - Creates a new service account for GCR read/write permissions
+  - Dumps the service account credential file into `./terraform/gcr_account.key.json`
+- [Kubernetes Engine](./terraform/gke.tf)
+- [KMS](./terraform/kms.tf)
+  - Creates a new service account for KMS read/write permissions
+  - Dumps the service account credential file into `./terraform/kms_account.key.json`
+  - Creates a new key ring and crypto key used for auto-unsealing Vault nodes
+- [DNS](./terraform/dns.tf)
+  - Creates a DNS zone for Vault
+  - Adds an A record for the chosen ingress IP
+  - Gives the cluster DNS admin permissions and dumps the service account credential file to `./terraform/dns_account.key.json`
+
+### Deployment
+
+You must enable the necessary Google API services, first, in order to successfully run the Terraform scripts to deploy the resources. There is a script to enable (and disable for teardown) the APIs for you:
+
+```bash
+./scripts/gcp_services.sh # [-d: disable]
+```
+
+This enables:
+
+- `compute.googleapis.com`
+- `cloudkms.googleapis.com`
+- `containerregistry.googleapis.com`
+- `iap.googleapis.com`
+- `iam.googleapis.com`
+- `container.googleapis.com`
+
+Without doing this first, the deployment will not succeed.
+
+> NOTE:
+> <br />
+> There are three variables that are networking CIDR blocks that must be set properly for a successful apply: `gke_pod_cidr`, `gke_service_cidr`, and `vault_subnet_cidr`. All three of there blocks must be different, but can whatever you'd like.
+> <br />
+> 
+> - `vault_subnet_cidr`: the CIDR block for the VPC subnet that the GKE cluster nodes will be created and restricted to
+> - `gke_service_cidr`: the CIDR block for all Kubernetes services and load balancer to be created within
+> - `gke_pod_cidr`: the CIDR block for the Kubernetes pods to be restricted to (must be a `/21` or lower mask per GCP restrictions)
+> <br />
+> 
+> Once created, each of these CIDR blocks will be automatically attached to the Vault subnet in the VPC to allow VPC peering to all three of the CIDR blocks. 
+
+Now that you're authenticated locally to your GCP project, you can now deploy the scripts. Ensure that you have all of the necessary Terraform variables set in the `terraform.tfvars` file and run:
+
+```bash
+cd ./terraform
+terraform init
+terraform plan
+terraform apply
+```
+
+The deployment could take some time because of spinning up a new GKE cluster, but once complete the two new service account credential key files (GCR and KMS service account) will be created within the `./terraform` directory.
+
+## Kubernetes
+
+### Credentials
+
+[Source](./k8s)
+
+Now that you have your GKE cluster running in a configured GCP project, you can setup your local Kubernetes configuration to point to the GKE cluster you've created. Assuming you are still authenticated to your project with the `gcloud` CLI, you can run:
+
+```bash
+export GKE_CLUSTER_NAME=$(gcloud container clusters list --format=json | jq -r '.[].name')
+gcloud container clusters get-credentials $GKE_CLUSTER_NAME --region $GCP_REGION
+```
+
+This will fetch and write new credentials for your GKE cluster into your local `~/.kube/config` file that you can inspect to verify the population. To verify the credentials assignment was ok, run:
+
+```bash
+kubectl config view
+```
+
+And validate that there is a cluster context for GKE with the format `gke_${PROJECT}_${REGION}_${CLUSTER}`, and that its set to your `current-context`. If it exists but is not your current context, you can enable it with:
+
+```bash
+kubectl config use-context $GKE_CONTEXT_NAME
+```
+
+And later _delete_ it (if necessary with):
+
+```bash
+kubectl config delete-context $GKE_CONTEXT_NAME
+kubectl config delete-cluster $GKE_CONTEXT_NAME
+kubectl config unset users.$GKE_CONTEXT_NAME
+kubectl config unset current-context
+```
+
+### KMS
+
+Due to the lifecycle restrictions on KMS resources by Google, this had to be removed from the Terraform as a separate step. A new KMS symmetric key must be created and injected into the Kubernetes cluster's secrets to be able to be pulled and read by the Vault nodes for auto-unseal.
+
+Assuming you have already run the Terraform and have the `kms_account.key.json` file generated for the service account under your `./terraform` directory, you can now run:
+
+> Note:
+>
+> Before running the KMS script, ensure you have the current Kubernetes context and credentials active for the GKE cluster.
+
+```bash
+./scripts/kms.sh -c ./terraform/kms_account.key.json -r $GCP_REGION
+```
+
+This script will activate the KMS service account in the `gcloud` tool using the generate credential file path provided and create a new KMS key ring and symmetric unsealing key within that ring for you (if one or both already exist, these steps will be skipped). Once the key ring and unsealer key have been created within your GCP project, the script [injects the service account credential file into cluster secrets to be mounted into the nodes for unsealing](https://www.vaultproject.io/docs/platform/k8s/helm/run#google-kms-auto-unseal) before revoke your `gcloud` authentication session.
+
+### DNS
+
+Run:
+
+```bash
+./scripts/dns.sh -c ./terraform/dns_account.key.json
+```
+
+This will grant the cluster permissions to write to DNS for certificate verification.
+
+If DNS for the domain is managed by another provider than Google's Cloud DNS (e.g. Cloudflare), an NS record can be added so that queries for a Vault subdomain are delegated to Google's nameservers.
+
+### Helm / Deployment
+
+Deploying services to a Kubernetes cluster typically require the use of [helm](https://helm.sh) to manage the cluster configuration and dependencies. This guide shows how to use the official [Hashicorp](https://www.hashicorp.com) _helm chart_ to deploy a Vault cluster.
+
+#### Installing Helm and Supporting Tools
+
+If you are running on MacOS, you can install helm by executing:
+
+```bash
+brew install helm yq
+```
+
+If you are running on Linux or Windows, see the [Helm Download Page](https://github.com/helm/helm/releases/latest). You'll also want to install the yq utility.
+
+#### Establish Remote Registries
+
+In order to use the official Hashicorp and Datadog Helm repositories, we need to add it to the local helm registry by executing:
+
+```bash
+helm repo add hashicorp https://helm.releases.hashicorp.com
+helm repo add datadog https://helm.datadoghq.com
+helm repo add stable https://kubernetes-charts.storage.googleapis.com
+helm repo update
+```
+
+#### Datadog
+
+In the [Datadog overrides file](./k8s/datadog-overrides.yaml), insert your Datadog API and App key into the YAML file at `.datadog.apiKey` and `.datadog.appKey` respectively.
+
+From the `infrastructure` folder, execute the following command to deploy the Datadog Helm chart:
+
+```sh
+helm upgrade --atomic --cleanup-on-fail --install --values ./k8s/datadog-overrides.yaml datadog datadog/datadog
+```
+
+With the existing overrides (in addition to your API and app keys), this Helm chart instantiates a DaemonSet for the Datadog agent pods that will be responsible for collecting and forwarding Vault server and audit logs into your Datadog dashboards.
+
+#### Vault
+
+##### Install cert-manager
+
+If using ingress and an external certificate to access the Vault cluster, define this in k8s/cert-manager-issuers/values.yaml
+
+To install cert-manager to generate SSL certificates for Vault:
+
+```bash
+helm dep up ./k8s/cert-manager
+helm install cert-manager ./k8s/cert-manager
+helm install cert-manager-issuers ./k8s/cert-manager-issuers
+```
+
+##### Install traefik
+
+To install traefik for HTTPS ingress
+
+```bash
+helm dep up ./k8s/traefik
+helm install traefik ./k8s/traefik
+```
+
+
+##### Configuring the vault chart
+
+In `infrastructure`, execute:
+
+```bash
+./scripts/gen_overrides.sh
+```
+
+You can supply the `--help` option to see what options are available. If you have the following environment variables set, it will use these values as defaults:
+
+```bash
+$GCP_REGION
+$GCP_PROJECT
+$GKE_CLUSTER_NAME
+```
+
+This updates the values.yaml file to correspond to your cluster.
+
+##### Start the Pods using the Helm Chart
+
+In `k8s`, execute:
+
+Execute:
+
+```bash
+
+helm dep up ./k8s/vault
+helm install vault ./k8s/vault
+```
+
+#### Sanity check
+
+At this point, you should see the following:
+
+```

+
+### Interact with Vault
+
+The easiest way to interact with Vault is to install Vault locally and use port forwarding:
+
+```
+kubectl port-forward service/vault 8200:8200
+export VAULT_ADDR=https://127.0.0.1:8200
+```
+
+#### Logs
+
+You can see the vault logs by executing:
+
+```bash
+kubectl logs vault-0
+```
+
+Before you initialize vault, you'll see errors like this:
+
+```
+2020-08-21T03:26:41.607Z [INFO]  core: stored unseal keys supported, attempting fetch
+2020-08-21T03:26:41.684Z [WARN]  failed to unseal core: error="fetching stored unseal keys failed: failed to decrypt encrypted stored keys: failed to decrypt envelope: rpc error: code = InvalidArgument desc = Decryption failed: verify that 'name' refers to the correct CryptoKey."
+```
+
+#### Access Vault using the CLI
+
+In another terminal, execute:
+
+```bash
+vault status -tls-skip-verify
+```
+
+The status command may not work yet if the Vault Server isn't initialized.
+
+#### Initialize Vault
+
+```bash
+vault operator init -format=json > cluster-keys.json -tls-skip-verify
+vault status -tls-skip-verify
+```
+
+At this point, Vault should be up and the vault-active service should have a backend. From now on, use:
+
+```kubectl port-forward service/vault-active 8200:8200```
+
+#### Load the Immutability plugin
+
+```
+PLUGIN_NAME="immutability-eth-plugin"
+INTERNAL_CERT_DIR="/vault/userconfig/vault-internal-certificate"
+CA_CERT="$INTERNAL_CERT_DIR/ca.crt"
+TLS_CERT="$INTERNAL_CERT_DIR/tls.crt"
+TLS_KEY="$INTERNAL_CERT_DIR/tls.key"
+SHA256SUM=$(kubectl exec vault-0 -- cat /vault/plugins/SHA256SUMS | cut -d' ' -f1)
+
+vault write -tls-skip-verify "sys/plugins/catalog/secret/$PLUGIN_NAME" \
+    sha_256="$SHA256SUM" \
+    command="$PLUGIN_NAME --ca-cert=$CA_CERT --client-cert=$TLS_CERT --client-key=$TLS_KEY"
+
+
+vault write "sys/plugins/catalog/secret/$PLUGIN_NAME" -tls-skip-verify \
+    sha_256="$SHA256SUM" \
+    command="$PLUGIN_NAME -tls-skip-verify"
+
+vault secrets enable -tls-skip-verify -path="$PLUGIN_NAME" -plugin-name="$PLUGIN_NAME" plugin
+```
+
+#### Enable Auditing
+
+```bash
+vault audit enable file file_path=/vault/audit/audit.log
+```
+
+#### Backup Vault RAFT Data to a Snapshot File
+
+Determining how many backup files you want to keep is a business decision. There are different strategies for maintaining a set of backup snapshots that can be employed.
+
+*Time-based strategy*. The snapshot filename is derived from the formatted timestamp. In this strategy, you'll have to determine how many snapshots to maintain and how to rotate them out when they're no longer appropriate.
+
+```bash
+vault operator raft snapshot save snapshot-$(date +%Y%m%d-%H%M%S).raft
+```
+
+*Rotational strategy*. Maintain a most-recent set of snapshots. This is implemented in a script and can be used as follows:
+
+In `infrastructure`, execute:
+
+```bash
+./scripts/vault_backup.sh -d <dest-dir> [-p <file-prefix>] [-m <max-backups>] [--help]
+``
+
+#### Restore Vault RAFT Data from a Snapshot File
+
+When you need to restore your Vault cluster back to a known-good state, identify the snapshot-file you want to restore and execute this command:
+
+```bash
+vault operator raft snapshot restore snapshot-file.raft
+````
+
+If using the *Rotational strategy*, this is implemented in a script and can be used as follows:
+
+In `infrastructure`, execute:
+
+```bash
+./scripts/vault_restore.sh -s <src-dir> [-p <file-prefix>] [-b <backup-number>] [--help]
+```
+
+---
+
+### Uninstalling Vault
+
+When you're done, you can uninstall vault.
+
+```bash
+helm uninstall vault
+```

+# OMGX_Messenger_Relayer_Fast
+
+Customized L1 Cross Domain Messenger without dispute period time restrictions and associated message relayer service.
+
+The custom `OVM_L1CrossDomainMessenger` works with the default `OVM_L2CrossDomainMessenger`. The messages from the L2_Messenger can be relayed by the custom messenger instead to skip the dispute period and to do that, the bridge/token contract should specify the custom messenger to be the messenger for relays. The custom messenger cannot be used to send cross domain messages. For sending messages the bridge contracts use the default L1_Messenger.
+
+## Using the custom messenger
+
+- Deploy `contracts/OVM_L1_CrossDomainMessenger.sol` on L1, this will be the contract used by your contracts for L2->L1 message passing
+
+- Your bridge/gateway contract must implement `contracts/libraries/OVM_CrossDomainEnabled.sol` instead. This uses the default L1 Messenger to send messages and the custom L1 Messenger to relay.
+
+## Running the Custom Messenger + Relayer
+
+- To deploy the custom messenger and start up the associated relayer run-
+```
+yarn start
+```
+
+- To run tests
+```
+yarn test:integration
+```
+
+## env settings
+
+Use .env.example for quick tests
+
+```
+
+ADDRESS_MANAGER_ADDRESS= <address manager contract address>
+L1_NODE_WEB3_URL= <l1 node url>
+L2_NODE_WEB3_URL= <l2 node url>
+L1_WALLET_KEY= <l1 wallet key>
+L1_MESSENGER_ADDRESS= <l1 custom messenger address>
+L1_WALLET_KEY= <private_key account for relayer>
+L1_TARGET= <target contract to allow relays to, set to 0x0 to skip>
+
+```
+
+for tests
+```
+

+
+```
+
+optional - while running message relayer for specific custom messenger
+```
+L1_MESSENGER_FAST= <optional>
+```
+
+### Additional Setting for stopping failed relay attempts
+
+- Add the target contract to the default message relayer's blacklist
+- Set the L1_TARGET=<target_contract> for custom message relayer
+
+### Deploying only Custom messenger
+
+Deploy with the deployer private key to also register the custom messenger
+```
+yarn deploy:contracts
+```
+
+#### Deploying only Custom Relayer
+
+```
+yarn start:service
+```
+
+This starts the service for the registered custom messenger. Specify L1_MESSENGER_FAST=<messenger> to spin up the relayer for your messenger
+
+## Build a DockerHub Message Relayer Fast
+
+To build the Message Relayer Fast docker image:
+
+```bash
+
+docker build . --file Dockerfile.message-relayer-fast --tag omgx/message-relayer-fast:latest
+docker push omgx/message-relayer-fast:latest
