Sourcify

checkContractVerification

Free

Check whether a smart contract address has verified source code on Sourcify, on one EVM chain or across every chain where it is deployed, with the match quality. Use it to vet a token, protocol or contract before interacting with it: unverified code cannot be audited.

Try it
