Problem:CRC20 standard is not settled down and documented

[yihuang]

Early stage proposal

native denom conversion

• mint_by_cronos_module(address user, uint256 amount)
• burn_by_cronos_module(address user, uint256 amount)
• native_denom() returns (string)

bridge call

• send_to_ibc(address recipient, uint256 amount)
• send_to_ethereum(address recipient, uint256 amount)

native call events

• __CronosSendToAccount(address recipient, uint256 amount)
• __CronosSendToEthereum(address eth_recipient, uint256 amount, uint256 bridge_fee)
• __CronosSendToIBCChannel(address recipient, uint256 amount)

I think this issue can be closed now, given we've been using https://github.com/crypto-org-chain/cronos/blob/main/contracts/src/ModuleCRC20.sol?

Or we will only close after we add some proper documentation?
Should the documentation be an ADR in https://github.com/crypto-org-chain/cronos/tree/main/docs/architecture? If not, where else is best to place it? @yihuang @tomtau @calvinaco @thomas-nguy thanks ahead!

I would say

• Write ADR for the bridge solution ETH <-> Cronos which document the hook logic and ModuleCRC20 contract
• For CRC20 standard or other CRCXX standard, lets open a new repository

For now CRC20 and ModuleCRC20 are almost the same, so we could just create an ADR

Consider it fixed by the new repo: https://github.com/crypto-org-chain/cronos-public-contracts.
