Creates a new transaction object.

Parameters

  • data Buffer or Array or Object a transaction can be initiailized with either a buffer containing the RLP serialized transaction or an array of buffers relating to each of the tx Properties, listed in order below in the exmple.Or lastly an Object containing the Properties of the transaction like in the Usage example.For Object and Arrays each of the elements can either be a Buffer, a hex-prefixed (0x) String , Number, or an object with a toBuffer method such as Bignum
    • data.chainId Number EIP 155 chainId - mainnet: 1, testnet: 3
    • data.nonce Buffer nonce number
    • data.gasLimit Buffer transaction gas limit
    • data.gasPrice Buffer transaction gas price
    • data.to Buffer to the to address
    • data.Txtype Buffer Txtype (0x01 for normal, 0x06 for private)
    • data.data Buffer this will contain the data of the message or the init of a contract
    • data.v Buffer EC recovery ID
    • data.r Buffer EC signature parameter
    • data.s Buffer EC signature parameter
    • data.value Buffer the amount of ether sent

Properties

  • raw Buffer The raw rlp encoded transaction

var rawTx = {
  Txtype: '0x01',
  nonce: '0x00',
  gasPrice: '0x09184e72a000',
