1. checkContractVerificationCheck 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.Free
2. getVerifiedContractDetails of a smart contract verified on Sourcify: contract name, compiler and settings, license, deployer and deployment transaction, whether it is a proxy and its implementation, its functions and events, and optionally the main source file. Use it to understand what a contract does and who deployed it.Free
3. decodeFunctionSelectorsDecode EVM function selectors (4 bytes, or the first 4 bytes of calldata) and event topics (32 bytes) into readable signatures such as transfer(address,uint256), using the Sourcify signature database. Use it to understand what a transaction or a signature request will actually call, e.g., spotting a hidden approve or setApprovalForAll.Free
