multichain-secure-wallet

A zero-dependency TypeScript library that generates multi-chain wallets using BIP-39 / BIP-32 / BIP-44 standards.
Works in Node.js ≥18, supports both TypeScript and JavaScript projects.

Developed by Onur Nizam.

✨ Features

• 🔑 Mnemonic generation (BIP-39, 12–24 words, English wordlist included)
• 🔒 Seed derivation with PBKDF2-HMAC-SHA512
• 🌐 BIP-32 / BIP-44 derivation
• 🪙 Multi-chain support:
  • Bitcoin (BTC)
  • Ethereum (ETH)
  • Litecoin (LTC)
  • Dogecoin (DOGE)
  • Binance Smart Chain (BSC)
  • Polygon (MATIC)
• 📦 Works in both TypeScript and JavaScript
• 🚫 Zero runtime dependencies

📦 Installation

npm install multichain-secure-wallet

🚀 Usage
JavaScript

const { generateWallet } = require('multichain-secure-wallet');

(async () => {
  const eth = await generateWallet({ language: 'english', blockchain: 'eth', strength: 128 });
  console.log(eth.address, eth.mnemonic, eth.privateKeyHex);
})();

TypeScript

import { generateWallet } from 'multichain-secure-wallet';

(async () => {
  const btc = await generateWallet({ language: 'english', blockchain: 'btc' });
  console.log(btc.address, btc.mnemonic, btc.privateKeyHex);
})();

Example Output

  "mnemonic": "abandon ability able about above absent absorb abstract absurd abuse access accident",
  "seedHex": "5eb00bbddcf069084889a8ab9155568165f5c453ccb85e70811aaed6f6da5fc1",
  "path": "m/44'/60'/0'/0/0",
  "coinType": 60,
  "privateKeyHex": "4c0883a69102937d6231471b5dbb6204fe512961708279cd27a3c6f6c7e0d85d",
  "publicKeyHex": "04a34f3c...f23bc7",
  "address": "0x1234abcd5678ef9012345678abcdef9012345678"
}

🧩 Roadmap

Done - BTC / ETH / LTC / DOGE / BSC / MATIC support

Coming soon - Bech32 (SegWit, Taproot)

Coming soon - Cosmos (ATOM), XRP, Tezos (XTZ)

Coming soon - Solana (SOL), Polkadot (DOT), Cardano (ADA)

🛡️ Security

Uses Node.js crypto module only (CSPRNG, HMAC, PBKDF2)

No telemetry, no logs, no external dependencies.

Always keep your mnemonic and private keys secure.
