    function _validate_ft4_signature(flags: list<text>, account: account, auth_descriptor: account_auth_descriptor)
    source

    Verifies that the signature found in the ft_auth operation is valid to authorize the operation being called.

    Can only be called from an operation.

    Throws if the signature cannot be validated. Common reasons include:

    • the signers of the auth descriptor did not sign this transaction
    • too few signers signed the operation, in case of a multisig auth descriptor
    • the auth descriptor does not give sufficient permissions for the operation that is being called

    Parameters

    • flags — the flags required by the operation
    • account — the account the user authenticated as
    • auth_descriptor — the auth descriptor that is authorizing this operation
