Web3 Integration

ethers-send.js

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider('https://go.getblock.io/<ACCESS-TOKEN>/');
const wallet = new ethers.Wallet(privateKey, provider);

const tx = {
    to: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb',
    value: ethers.parseEther('1.0'),
    gasLimit: 21000
};

const txResponse = await wallet.sendTransaction(tx);
console.log('Transaction hash:', txResponse.hash);

// Wait for confirmation (fast on Monad!)
const receipt = await txResponse.wait();
console.log('Confirmed in block:', receipt.blockNumber);
