This is a script for creating and sending an Ethereum transaction using the Web3 library and EthereumJS. It demonstrates how to set up the transaction parameters, sign it with a private key, and send it using Ganache, a local Ethereum blockchain emulator. Feel free to use and modify this code for your Ethereum-related projects.

transfer.js

const { Web3 } = require('web3');
const EthereumTransaction = require('ethereumjs-tx').Transaction;

// Step 1: Set up the appropriate configuration
const web3 = new Web3(new Web3.providers.HttpProvider('http://127.0.0.1:7545'));

async function transfer() {
    // Step 2: Set the sending and receiving addresses for the transaction
    const sendingAddress = 'sendingAddress';
    const receivingAddress = 'receivingAddress';

    // Step 3: Check the balances of each address
    const checkBalance = async (address) => {
        const balance = await web3.eth.getBalance(address);
        console.log(`Balance of ${address}: ${balance}`);
    };

    await Promise.all([checkBalance(sendingAddress), checkBalance(receivingAddress)]);

    // Step 4: Create a transaction
    const nonce = await web3.eth.getTransactionCount(sendingAddress, 'latest');
    console.log('Nonce:', nonce);

    const transaction = {
        to: receivingAddress,
        value: web3.utils.toWei('1', 'ether'),
        gasPrice: 765625000, // Gas price from network info
        gasLimit: 30000,     // Gas limit from network info
        nonce: nonce,
        data: web3.utils.toHex('Test')
    };

    const privateKey = 'privateKey';
    const signedTx = await web3.eth.accounts.signTransaction(transaction, privateKey);
    const rawTransaction = signedTx.rawTransaction;

    console.log(`Nonce for address ${sendingAddress} is: ${nonce}`);
    console.log('Raw transaction:', rawTransaction);

    web3.eth.sendSignedTransaction(rawTransaction, (error, hash) => {
        if (!error) {
            console.log(`The hash of your transaction is: ${hash}\nCheck Transactions tab in Ganache to view your transaction!`);
        } else {
            console.log('Something went wrong while submitting your transaction:', error);
        }
    });
}
