Check whether a smart contract's source code is verified on Sourcify, the open verification registry, by chain id (Base is 8453, Ethereum 1) and address, with the date it was verified. A contract not on Sourcify fails; it may still be verified elsewhere, so a fail means "not verified on Sourcify", nothing stronger.
