    function _validate_evm_address(message: text, signature: signature?, account_auth_descriptor: account_auth_descriptor): byte_array
    source

    Verifies that the signer of a certain message is the signer of the single-sig auth descriptor used to authorize this operation.

    Throws "INPUT ERROR" if the signature is null

    Throws "INVALID SIGNATURE" when the signature verification fails. This might happen if:

    • the message signer is not the one associated with the auth descriptor
    • the message that was signed does not correspond to the one passed in the message parameter

    Throws if the message is empty

    Parameters

    • message — the message that was signed
    • signature — the signature received. If null, it will throw
    • account_auth_descriptor — the auth descriptor that authorized this operation

    Returns

    the EVM address that signed the operation's message
