Wallet Generator

Simple and powerful utility for generating and managing multicurrency crypto wallets. Provides easy-to-use functions to generate mnemonics, compatible with EVM and blockchains, retrieve wallet addresses and private keys and verify mnemonics.

Features

• Generate BIP39 mnemonics
• Create EVM-compatible wallets (Ethereum, etc.)
• Retrieve wallet addresses from mnemonics
• Extract private keys from mnemonics
• Verify the validity of mnemonics

Installation

Install multi-wallet-generator using npm:

npm install multi-wallet-generator
yarn add multi-wallet-generator

Test

• To run the tests , use the npm command:

 npm run test

Usage

• Below are some examples of how to use the wallet-generator library:

Generate a Mnemonic

import { MultichainWalletWrapper } from 'wallet-generator';

async function generateMnemonic() {
  const mnemonic = await MultichainWalletWrapper.generateMnemonic();
  console.log(`Mnemonic: ${mnemonic}`);
}
// Note: Mnemonics with less than 12 words have low entropy and may be guessed by an attacker.
generateMnemonic();

Create an EVM Wallet and Display Mnemonic

async function createWallet() {
  const { address, mnemonic } = await MultichainWalletWrapper.createWalletEVMAndDisplayMnemonic();
  console.log(`Address: ${address}`);
  console.log(`Mnemonic: ${mnemonic}`);
}
createWallet();

• Response

{
  address: '0xfBE11AC0258cc8288cA24E818691Eb062f7042E9',
  mnemonic: 'net idle lava mango another capable inhale portion blossom fluid discover cruise'
}

Get EVM Wallet Address from Mnemonic

async function getAddress() {
  const mnemonic = "Contributions are welcome! Please feel free to submit a pull request or open an issue"
  const address = await MultichainWalletWrapper.getEvmWalletAddress(mnemonic);
  console.log(`Address: ${address}`);
}

getAddress();

Retrieve Private Key for EVM Wallet

 async function getPrivateKey() {
  const mnemonic = "net idle lava mango another capable inhale portion blossom fluid discover cruise"
  const privateKey = await MultichainWalletWrapper.getPrivateKeyEVM(mnemonic);
  console.log(`Private Key: ${privateKey}`);
}

getPrivateKey();

• Response

{
  privateKey: '0xfdf745f45d1942feea79b4c0a3fc1ca67da366899f7e6cebaa06496806ca8127',
}

Verify a Mnemonic

async function verifyMnemonic() {
  const mnemonic = "net idle lava mango another capable inhale portion blossom fluid discover cruise"
  const isValid = await MultichainWalletWrapper.verifyMemonicEVM(mnemonic);
  console.log(`Is valid: ${isValid}`);
}

verifyMnemonic();

• Response
