QuickNode Core Workflow A

Overview

Build EVM transaction workflows: send ETH, interact with contracts, listen for events, and handle gas estimation.

Prerequisites

• Completed quicknode-hello-world
• A funded wallet (use testnet for development)

Instructions

Step 1: Send ETH Transaction

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider(process.env.QUICKNODE_ENDPOINT);
const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);

const tx = await wallet.sendTransaction({
  to: '0xRecipientAddress',
  value: ethers.parseEther('0.01'),
});
console.log(`TX sent: ${tx.hash}`);
const receipt = await tx.wait();
console.log(`Confirmed in block ${receipt!.blockNumber}, gas used: ${receipt!.gasUsed}`);

Step 2: Call Contract Write Function

const contractAddress = '0xYourContract';
const abi = ['function transfer(address to, uint256 amount) returns (bool)'];
const contract = new ethers.(contractAddress, abi, wallet);

 tx =  contract.(, ethers.(, ));
 receipt =  tx.();
.();
