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';

• Infura Provider: You connect to the Ethereum network using the Infura provider (infuraProvider), which allows you to interact with Ethereum nodes.
• Private Key: Replace 'YOUR_PRIVATE_KEY' with your Ethereum wallet’s private key (keep it secure).
• Recipient Address: Replace '0xRecipientEthereumAddress' with the Ethereum address you want to send Ether to.
• Gas and Fees: The gasLimit and gasPrice fields are required for sending transactions. The getGasPrice function retrieves the current gas price from the Infura node.
