senderTxHash	32-byte DATA	Hash of a transaction that is signed only by the sender. This value is always the same as `hash` for non fee-delegated transactions.
signatures	Array	An array of signature objects. A signature object contains three fields (V, R, and S). V contains ECDSA recovery id. R contains ECDSA signature r while S contains ECDSA signature s.
to	20-byte DATA	Address of the receiver. `null` when it is a contract creation transaction.
