    public class SignaturePayload
extends Struct
    A signing payload for an org.polkadot.type.extrinsics. For the final encoding, it is variable length based on the conetnts included 8 bytes The Transaction Index/Nonce as provided in the transaction itself. 2+ bytes The Function Descriptor as provided in the transaction itself. 2 bytes The Transaction Era as provided in the transaction itself. 32 bytes The hash of the authoring block implied by the Transaction Era and the current block.
