These include: • nonce: It is a sequence number for the sending account which counteracts replay attacks • gasprice: price offered to pay per gas • startgas: upper limit for the gas consumption • to: destination address (EoA or contract address) • value: Ether to transfer • data: Data to transfer • v, r, s: ECDA signature.
