Managing Accounts

This feature allows you to create and manage Ethereum accounts. The code sample demonstrates how to create a new Ethereum account using the web3-core package.

const Web3 = require('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');

// Create a new account
const account = web3.eth.accounts.create();
console.log(account);

Sending Transactions

This feature allows you to send transactions on the Ethereum network. The code sample demonstrates how to sign and send a transaction using the web3-core package.

const Web3 = require('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');

const transaction = {
  to: '0xRecipientAddress',
  value: web3.utils.toWei('0.1', 'ether'),
  gas: 2000000
};

web3.eth.accounts.signTransaction(transaction, 'YOUR_PRIVATE_KEY').then(signedTx => {
  web3.eth.sendSignedTransaction(signedTx.rawTransaction).on('receipt', console.log);
});

Interacting with Smart Contracts

This feature allows you to interact with smart contracts deployed on the Ethereum network. The code sample demonstrates how to call a method on a smart contract using the web3-core package.

const Web3 = require('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');

const contractABI = [/* ABI array */];
const contractAddress = '0xContractAddress';
const contract = new web3.eth.Contract(contractABI, contractAddress);

contract.methods.myMethod().call().then(console.log);
