Please note that Quicknode does not support the eth_signTransaction RPC method. To sign a transaction without a node-held key, see How to Sign Ethereum Transactions Locally. To use eth_signTransaction on the C-Chain, ensure that the end of your URL includes ext/bc/C/rpc.

Parameters

object

object

REQUIRED

The transaction response object which contains the following fields:

from

string

The address the transaction is sent from

to

string

(optional for contract creation) The address the transaction is directed to

gas

string

(default: 90000) The integer of the gas provided for the transaction execution

gasPrice

string

The integer of the gasPrice used for each paid gas, in wei

value

string

The integer of the value sent with this transaction, in wei

data

string

The compiled code of a contract or the hash of the invoked method signature and encoded parameters

nonce

string

The integer of a nonce. This allows overwriting the own pending transactions that use the same nonce

Returns

result

The signed transaction object
