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'
