Deploying smart contracts is a more advanced topic, but here’s an example of how you can use Ethers.js with Infura to deploy a smart contract:

const ethers = require('ethers');

// Replace with your Infura Project ID
const infuraProvider = new ethers.JsonRpcProvider('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');

// Replace with your private key
const privateKey = 'YOUR_PRIVATE_KEY';

// Create a wallet instance and connect it to Infura
const wallet = new ethers.Wallet(privateKey, infuraProvider);

// Contract bytecode and ABI
const bytecode = '0xYourContractBytecode';
const abi = [
    // Your contract ABI here
];

async function deployContract() {
    try {
        // Create a ContractFactory to deploy the contract
        const factory = new ethers.ContractFactory(abi, bytecode, wallet);

        // Deploy the contract
        const contract = await factory.deploy();

        // Wait for the contract to be mined
        console.log('Contract deployed at address:', contract.address);
        await contract.deployTransaction.wait();
    } catch (error) {
        console.error('Error deploying contract:', error);
    }
}

// Call the function to deploy the contract
deployContract();
