What is @ethersproject/address?

@ethersproject/address is a part of the ethers.js library, which provides utilities for handling Ethereum addresses. It includes functions for address validation, checksum address generation, and address formatting.

What are @ethersproject/address's main functionalities?

Address Validation

This feature allows you to check if a given string is a valid Ethereum address.

const { isAddress } = require('@ethersproject/address');

const address = '0x742d35Cc6634C0532925a3b844Bc454e4438f44e';
console.log(isAddress(address)); // true

Checksum Address Generation

This feature converts an Ethereum address to its checksummed version, which includes mixed-case letters to help prevent errors.

const { getAddress } = require('@ethersproject/address');

const address = '0x742d35Cc6634C0532925a3b844Bc454e4438f44e';
const checksumAddress = getAddress(address);
console.log(checksumAddress); // '0x742d35Cc6634C0532925a3b844Bc454e4438f44e'

Address Formatting

This feature formats an Ethereum address to its canonical form, ensuring consistency in address representation.

const { getAddress } = require('@ethersproject/address');

const address = '0x742d35Cc6634C0532925a3b844Bc454e4438f44e';
const formattedAddress = getAddress(address);
console.log(formattedAddress); // '0x742d35Cc6634C0532925a3b844Bc454e4438f44e'
