Usage

Generating a Wallet

You can create a new wallet with a randomly generated mnemonic phrase:

import { Wallet } from './index.js';

const wallet = new Wallet();
const mnemonic = wallet.generateMnemonic() // creates a randomly generated mnemonic phrase containing 12 words
wallet.generateKeypair(mnemonic) // Generates a keypair using the provided mnemonic and stores it internally

console.log(mnemonic);
console.log(wallet.publicKey.toString('hex')); // Prints the public key

You can also create a wallet with a specific mnemonic phrase:

const mnemonic = 'session attitude weekend sign collect mobile return vacuum pool afraid wagon client';
const wallet = new Wallet(mnemonic);
console.log(wallet.publicKey.toString('hex')); // Prints the public key

Signing and Verifying Messages

You can sign a message with the wallet's secret key and verify the signature with the public key:

const message = 'Hello, world!';
const signature = wallet.signMessage(message);
const isValid = wallet.verifySignature(message, signature, wallet.publicKey);
console.log(isValid); // Prints true if the signature is valid

Exporting Keys to a File

You can export the wallet's keys to a JSON file:

const filePath = './wallet.json';
wallet.exportToFile(filePath);

Running Tests

To run the tests, use the following command:
