eth_sendTransaction

: Creates new message call transaction or a contract creation, if the data field contains code.

• Parameters

  1. Object - The transaction object
  2. from: DATA, 20 Bytes - The address the transaction is send from.
  3. to: DATA, 20 Bytes - (optional when creating new contract) The address the transaction is directed to.
  4. data: DATA - The compiled code of a contract OR the hash of the invoked method signature and encoded parameters. For details see Ethereum Contract ABI
  5. gas: QUANTITY - (optional, default: 90000) Integer of the gas provided for the transaction execution. It will return unused gas.
  6. gasPrice: QUANTITY - (optional, default: To-Be-Determined) Integer of the gasPrice used for each paid gas
  7. value: QUANTITY - (optional) Integer of the value sent with this transaction
  8. nonce: QUANTITY - (optional) Integer of a nonce. This allows to overwrite your own pending transactions that use the same nonce.

• Returns

  DATA, 32 Bytes - the transaction hash, or the zero hash if the transaction is not yet available.
