The Web3 Signature is a utility library for verifying Ethereum signatures using multiple standards. It provides a unified interface to simplify the signature verification process in your Ethereum-related projects.

• Supports signature verification according to multiple standards.
  • EIP-191(0x00 and 0x45 version)
  • EIP-712(0x01 version)
  • EIP-1271
• Easy-to-use API for signature validation.
• Compatible with popular web3 libraries and Ethereum development tools.

You can install this package via npm: NPM:

npm install web3-signature

YARN:

yarn add web3-signature

Here's a basic example of how to use the package to verify an Ethereum signature:

import { SignatureVerifierFactory } from "web3-signature";

const verifier = SignatureVerifierFactory.createVerifier("EIP191");

// Sample signature and message
const address = '0x...'; // Replace with your wallet address
const signature = '0x...'; // Replace with your signature
const message = 'Hello, Ethereum!'; // Replace with your message

// Verify the signature
const isValid = verifier.verify({
  address,
  message, 
  signature,
});

if (isValid) {
  console.log('Signature is valid.');
} else {
  console.error('Signature is not valid.');
}
