Verify Contracts

Verify Contract (Standard JSON)

Submit a contract for verification via the Solidity standard JSON input or Vyper JSON input.

There are no "single file" or "multi-part" verification endpoints because those are essentially wrappers around the Solidity compiler's JSON interface. The verification frontend can provide files and settings options to resemble these.

You can optionally pass the creationTransactionHash to make Sourcify reliably fetching the creation bytecode. Otherwise, it will try to fetch it itself which is dependent on external services.

Note: The outputSelection field in the stdJsonInput.settings will be overridden during verification to ensure all necessary artifacts are generated.
