Erc-20 Tokens Development Tutorials, Guides & Insights

Once you’ve added the code, run the script:

node getTokenBalance.js

Let’s start by sending Ether from one account to another using Ethers.js and Infura.

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 wallet's private key
const privateKey = 'YOUR_PRIVATE_KEY';

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

// Replace with the recipient's Ethereum address
const recipientAddress = '0xRecipientEthereumAddress';

// Amount to send (in Ether)
const amountInEther = '0.01';

async function sendTransaction() {
    try {
        // Convert Ether to Wei (the smallest unit of Ether)
        const amountInWei = ethers.utils.parseEther(amountInEther);

        // Create the transaction
        const tx = {
            to: recipientAddress,
            value: amountInWei,
            gasLimit: ethers.utils.hexlify(21000), // Gas limit for basic transactions
            gasPrice: await infuraProvider.getGasPrice() // Get current gas price from Infura
        };

        // Send the transaction
        const transaction = await wallet.sendTransaction(tx);

        console.log('Transaction sent:', transaction.hash);

        // Wait for the transaction to be mined
        const receipt = await transaction.wait();
        console.log('Transaction confirmed:', receipt);
    } catch (error) {
        console.error('Error sending transaction:', error);
    }
}

// Call the function to send the transaction
sendTransaction();
