CyberChain Transaction Library

This library can be used to create, sign and serialize transactions meant to be sent to the CyberChain blockchain.

This is a fork of the tx package, from EthereumJS.

Installation

To obtain the latest version, simply require the project using npm:

npm install @cyberchain/tx

Usage

See the following code snipped for an example on how create and sign a transaction.

import {
  FeeMarketEIP1559TxData,
  FeeMarketEIP1559Transaction,
  SignKey,
} from "@cyberchain/tx";
import { Common } from "@ethereumjs/common";
import { Address } from '@ethereumjs/util';

const chainId = BigInt(1337);

function buildTransaction() {
  const customCommon = Common.custom(
    {
      name: "my-network",
      networkId: chainId,
      chainId: chainId,
    },
    {
      baseChain: "mainnet",
      hardfork: "london",
    }
  );

  const txData: FeeMarketEIP1559TxData = {
    to: "0x1111111111111111111111111111111111111111",
    data: "0x",
    value: BigInt(0),
    nonce: 1,
    gasLimit: BigInt(6000000),
    chainId: chainId,
    maxFeePerGas: 0,
    maxPriorityFeePerGas: 0,
  };

  // Create transaction
  let tx = new FeeMarketEIP1559Transaction(txData, { common: customCommon });

  // Sign transaction
  const signKey: SignKey = {
    type: "ec-dsa",
    key: Buffer.from("1111111111111111111111111111111111111111111111111111111111111111", "hex")
  };
  const complementaryAddress = new Address(Buffer.from("2222222222222222222222222222222222222222", 'hex'));

  tx = tx.sign(signKey, complementaryAddress);

  // Serialize transaction
  const serializedTx = tx.serialize();

  return serializedTx;
}
