    "ws://your-json-rpc-websocket.test",
  );
  final signedTransaction = await web3.sign(
    nonce: 9,
    to: "0x3535353535353535353535353535353535353535",
    gasLimit: BigInt.from(21000),
    gasPrice: BigInt.from(20 * pow(10, 9)),
    value: BigInt.from(pow(10, 18)),
    chainId: 1,
  );
}

Send a Transaction

Quickly sign and send a transaction.

import "package:nova/nova.dart";

void main() async {
  final web3 = Wallet(
    "0x4646464646464646464646464646464646464646464646464646464646464646",
    "ws://your-json-rpc-websocket.test",
  );
  final signedTransaction = await web3.send(
    nonce: 9,
    to: "0x3535353535353535353535353535353535353535",
    gasLimit: BigInt.from(21000),
    gasPrice: BigInt.from(20 * pow(10, 9)),
    value: BigInt.from(pow(10, 18)),
    chainId: 1,
  );
}

Send a raw transaction

Send a raw transaction if that is what you need.

import "package:nova/nova.dart";

void main() async {
  final web3 = Wallet(
    "0x4646464646464646464646464646464646464646464646464646464646464646",
    "ws://your-json-rpc-websocket.test",
  );
  await web3.sendRawTransaction(
    '0xf86c098504a817c800825208943535353535353535353535353535353535353535880de0b6b3a76400008025a028ef61340bd939bc2195fe537567866003e1a15d3c71ff63e1590620aa636276a067cbe9d8997f761aecb703304b3800ccf555c9f3dc64214b297fb1966a3b6d83',
