    verify_signers_with_message

    FT4 Library / FT4 Library / lib.ft4.core.auth
    function verify_signers_with_message(ft_and_evm_signers: list<byte_array>, message: text, gtx_transaction: gtx_transaction)
    source

    Does what verify_signers does, but receives the message as a parameter instead of using the auth message of the current operation.

    Throws "MISMATCHED SIGNATURES" if any of the signers and signatures on the evm_signatures operation don't match in the exact order they're found.

    Throws "MISSING SIGNATURE" if:

    • an EVM signer is specified but the signature is not found in the evm_signatures operation.
    • an FT signer is specified but the signature is not found in the signers of the transaction.

    Throws "UNSUPPORTED SIGNER" if a signer passed is neither an EVM nor an FT signer, which means the byte array length is different from EVM_ADDRESS_SIZE and FT_PUBKEY_SIZE

    Throws if the message is empty.

    Throws if any signatures in evm_signatures is null or missing, or if there's extra signatures in that operation.

    Parameters

    • ft_and_evm_signers — the signers that are expected to be found.
    • message — the message that was signed.
    • gtx_transaction — the transaction that was signed.

    • verify_signers — if the message that must be signed is the one defined in the auth_handler for the current operation
