Creates new message call transaction or a contract creation.


May need to verify your account information in the request.


Note that the interactive example in this page will not work, due to the fact that eth_sendTransaction is used to modify the state of the blockchain, it is not possible to duplicate the same request.


Creates new message call transaction or a contract creation, if the data field contains code, and signs it using the account specified in from.


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

    gasPrice: "0x9184e72a000", // 10000000000000  
    value: "0x9184e72a", // 2441406250  


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

Use eth_getTransactionReceipt to get the contract address, after the transaction was mined, when you created a contract.
