@ethersproject/wallet

What is @ethersproject/wallet?

@ethersproject/wallet is a part of the ethers.js library, which provides a complete, tiny, and simple library for interacting with the Ethereum blockchain. The wallet module specifically deals with creating and managing Ethereum wallets, signing transactions, and interacting with the Ethereum network.

What are @ethersproject/wallet's main functionalities?

Creating a Wallet

This feature allows you to create a new Ethereum wallet with a random private key. The code sample demonstrates how to create a new wallet and print its address.

const { Wallet } = require('@ethersproject/wallet');
const wallet = Wallet.createRandom();
console.log(wallet.address);

Importing a Wallet from a Private Key

This feature allows you to import an existing wallet using a private key. The code sample demonstrates how to create a wallet from a given private key and print its address.

const { Wallet } = require('@ethersproject/wallet');
const privateKey = '0x0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef';
const wallet = new Wallet(privateKey);
console.log(wallet.address);

Signing a Message

This feature allows you to sign a message using the wallet's private key. The code sample demonstrates how to sign a message and print the resulting signature.

const { Wallet } = require('@ethersproject/wallet');
const wallet = Wallet.createRandom();
const message = 'Hello, Ethereum!';
wallet.signMessage(message).then(signature => {
  console.log(signature);
});

Sending a Transaction

This feature allows you to send a transaction from the wallet. The code sample demonstrates how to connect the wallet to a provider and send a transaction to a recipient address.

const { Wallet } = require('@ethersproject/wallet');
const { providers } = require('@ethersproject/providers');
const wallet = Wallet.createRandom();
const provider = new providers.JsonRpcProvider('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
const walletWithProvider = wallet.connect(provider);
const tx = {
  to: '0xrecipientAddress',
  value: ethers.utils.parseEther('0.01')
};
walletWithProvider.sendTransaction(tx).then(transaction => {
  console.log(transaction);
});

Other packages similar to @ethersproject/wallet

web3

web3.js is a collection of libraries that allow you to interact with a local or remote Ethereum node using HTTP, IPC, or WebSocket. It provides similar functionalities to @ethersproject/wallet, such as creating and managing wallets, signing transactions, and interacting with the Ethereum network. However, web3.js is generally considered to be more heavyweight and has a steeper learning curve compared to ethers.js.

eth-lightwallet

eth-lightwallet is a lightweight JavaScript library for creating and managing Ethereum wallets. It provides functionalities for generating wallets, encrypting and decrypting private keys, and signing transactions. Compared to @ethersproject/wallet, eth-lightwallet is more focused on lightweight operations and is often used in browser environments.

ethereumjs-wallet

ethereumjs-wallet is a simple library for creating and managing Ethereum wallets. It provides functionalities for generating wallets, importing wallets from private keys, and signing transactions. Compared to @ethersproject/wallet, ethereumjs-wallet is more minimalistic and focuses solely on wallet management without additional features for interacting with the Ethereum network.
