Sourcify (sourcify.dev) is a source-code verification service for Ethereum smart contracts supporting Solidity and Vyper. Sourcify is fully commited to

• Open-source
• Open-data (see Downloading the repository)
• Open-standards (see the Verifier Alliance)

in smart-contract verification instead of siloed, propriety services. We foster these values across the ecosystem and work actively to push the status-quo in this direction.

Different than other verification services, Sourcify leverages the Solidity metadata and file and its integrity hash to "fully verify" the Solidity contracts (see the playground).

Sourcify mainly consists of:

• sourcify-server - an HTTP server to run source-code verifications and store the verified contracts for the supported chains through an API
• sourcify-monitor - a standalone service that listens to various EVM chains for new contract creations and automatically submits them to a Sourcify API for verification if published on IPFS.
• Packages:
  • @ethereum-sourcify/lib-sourcify: The core library for Sourcify. It contains the logic to verify contracts.
  • @ethereum-sourcify/bytecode-utils: A library to extract and parse the CBOR encoded metadata from the bytecode.
• Sourcify UI - a web UI to interact with the server, lookup, and verify contracts

ℹ️ This monorepo contains the main modules. The sourcifyeth Github organization contains all other auxiliary services and components.

How we work

Sourcify aims to be fully open and transparent. You can see what we are working day-to-day on on our Public Issue Board as well our Quarterly Milestones for our longer term plans.

Adding a new chain

If you'd like to add a new chain support to Sourcify please follow the chain support instructions in docs.

Sourcify is an Argot Collective project
