`senderV, senderR, senderS` is a signature of an RLP array of the items preceding the sender signature items. The address recovered from this signature is the address of `msg.sender` for the transaction and the address whose `nonce` is used.
`gasPayerV, gasPayerR, gasPayerS` is a signature of an RLP array of the items preceding the gas payer signature items. The address recovered from this signature is the address of `tx.origin` for the transaction, and the address whose ETH balance the gas costs for the transaction are deducted from.
`senderV, senderR, senderS` is a signature of an RLP array of the items preceding the sender signature items. The address recovered from this signature is the address returned by the `CALLER` opcode (0x33, aka `msg.sender`) for the first level of the transaction, and the address whose `nonce` is used, and the address whose ETH is deducted if any value is attached to the transaction.
`gasPayerV, gasPayerR, gasPayerS` is a signature of an RLP array of the items preceding the gas payer signature items. The address recovered from this signature is the address returned by the `ORIGIN` opcode (0x32, aka `tx.origin`) for the transaction, and the address whose ETH balance the gas costs for the transaction are deducted from.

Both signatures for this transaction type have a `v` value that is either `0` or `1` and represents the parity of the `y` value of the ECDSA signing process.
