What are web3-eth-accounts's main functionalities?

Create Account

This feature allows you to create a new Ethereum account. The account object contains the address, private key, and other relevant information.

const Web3 = require('web3');
const web3 = new Web3();
const account = web3.eth.accounts.create();
console.log(account);

Sign Transaction

This feature allows you to sign a transaction using an account's private key. The signed transaction can then be sent to the Ethereum network.

const Web3 = require('web3');
const web3 = new Web3();
const account = web3.eth.accounts.privateKeyToAccount('YOUR_PRIVATE_KEY');
const tx = {
  to: '0xRecipientAddress',

  gas: 2000000
};
account.signTransaction(tx).then(signed => {
  console.log(signed);
});

Recover Account

This feature allows you to recover an account address from a signed message. It is useful for verifying the authenticity of a message.

const Web3 = require('web3');
const web3 = new Web3();
const message = 'Hello, world!';
const signature = '0xSignature';
const account = web3.eth.accounts.recover(message, signature);
console.log(account);

Sign Data

This feature allows you to sign arbitrary data using an account's private key. The signed data can be used for various purposes, such as authentication.

const Web3 = require('web3');
const web3 = new Web3();
const account = web3.eth.accounts.privateKeyToAccount('YOUR_PRIVATE_KEY');
const data = 'Hello, world!';
const signature = account.sign(data);
console.log(signature);
