Wallet Balance Development Tutorials, Guides & Insights

• Decentralized Applications (dApps): If you’re building an application that needs to interact with Ethereum in real-time, such as sending transactions or calling smart contract functions.
• Wallets: If you are developing a wallet application that needs to sign and broadcast transactions.
• Smart Contract Deployment: Use Infura to deploy or interact with smart contracts on the Ethereum blockchain.

• Rate Limits: Etherscan’s free tier limits the number of API requests per second (usually around 5 per second). This is fine for querying data but can be limiting for large-scale applications that need to process a lot of data quickly.
• Pricing: Etherscan offers paid tiers that increase the API request limits.

const ethers = require('ethers');

// Replace this with your Ethereum wallet's private key or mnemonic phrase
const privateKey = 'YOUR_PRIVATE_KEY_OR_MNEMONIC';

// Use a public Ethereum node URL (this is a public node for demonstration purposes)
const publicProvider = new ethers.JsonRpcProvider('https://mainnet.publicnode.com');

// Create a wallet instance using your private key and connect it to the public node provider
const wallet = new ethers.Wallet(privateKey, publicProvider);

// Function to get the balance of the wallet
async function getWalletBalance() {
    // Get the wallet's balance in wei
    const balanceInWei = await wallet.getBalance();

    // Convert the balance from wei to Ether for readability
    const balanceInEther = ethers.utils.formatEther(balanceInWei);

    // Log the results
    console.log(`Wallet Address: ${wallet.address}`);
    console.log(`Wallet Balance: ${balanceInEther} ETH`);
}

// Execute the function
getWalletBalance();

• Replace 'YOUR_PRIVATE_KEY_OR_MNEMONIC' with your actual Ethereum wallet's private key or mnemonic phrase.
• For the Infura method, replace 'YOUR_INFURA_PROJECT_ID' with the Infura Project ID you received when you created your Infura account.
