Sample Code: Using Ethers.js

Here’s a simple example demonstrating how to use Ethers.js to connect to the Ethereum network and retrieve the balance of an Ethereum address:

        
            // Import the Ethers.js library
            const { ethers } = require("ethers");

            async function getBalance() {
                // Connect to the Ethereum mainnet
                const provider = new ethers.providers.InfuraProvider("mainnet", "YOUR_INFURA_PROJECT_ID");

                // Specify the Ethereum address
                const address = "0x742d35Cc6634C0532925a3b844Bc454e4438f44e"; // Example address

                // Get the balance
                const balance = await provider.getBalance(address);
                console.log("Balance of address:", ethers.utils.formatEther(balance), "ETH");
            }

            getBalance().catch((error) => {
                console.error("Error fetching balance:", error);
            });
