NPM: https://www.npmjs.com/package/@hdwallet/core

Overview

hdwallet.js is a new TypeScript/JavaScript port of the popular Python-HDWallet library. It brings the full suite of hierarchical deterministic (HD) wallet features like mnemonic generation, BIP standard derivations, curve support, and multi-chain compatibility to the JavaScript ecosystem. It works great in browsers, Node.js, and React Native, making it an open-source HD wallet tool that’s perfect for modern Web3 applications.

If you want to learn more about the original Python-HDWallet and its integration of XinFin (XDC) support, check out my previous post: ⚙️ Introducing HDWallet V3 & XDC Integration

Why We Built It

As Web3 projects started needing frontend or serverless key generation, it became clear that a secure and flexible HD wallet solution in JavaScript was essential. Inspired by the features of python-hdwallet, this port gives developers the same deterministic structure, now easily used in browser extensions, React Native apps, or decentralized platforms—all while keeping strong cryptographic security.

Why TypeScript/JavaScript Now?

Python is still great for backend scripting, but a lot of developers have been asking for a native JS solution because:

• It allows secure in-browser key generation on the client side
• It works seamlessly with React, Angular, Vue frontends, and React Native
• It integrates with popular tools like ethers.js, web3.js, and hardware wallets

This growing demand led to the creation of hdwallet.js: a modern, reliable port built specifically for the JavaScript ecosystem.

Core Highlights

Quick Example for XDC

Here’s how you might derive an XinFin address using hdwallet.js

Library

Installation: npm install @hdwallet/core

// xinfin.hdwallet.ts

import { HDWallet } from '@hdwallet/core';
import { BIP39Mnemonic } from '@hdwallet/core/mnemonics';
import { XinFin } from '@hdwallet/core/cryptocurrencies';
import { BIP44Derivation, CHANGES } from '@hdwallet/core/derivations';
import { PUBLIC_KEY_TYPES } from '@hdwallet/core/consts';
import { BIP44HD } from '@hdwallet/core/hds';

// Initialize XinFin HDWallet
const hdwallet: HDWallet = new HDWallet(
  XinFin, {
    hd: BIP44HD,
    network: XinFin.NETWORKS.MAINNET,
    publicKeyType: PUBLIC_KEY_TYPES.COMPRESSED,
    passphrase: null
  }
).fromMnemonic(   // Get XinFin HDWallet from mnemonic phrase
  new BIP39Mnemonic(
    "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about"
  )
).fromDerivation(   // Drive from BIP44 derivation
  new BIP44Derivation({
    coinType: XinFin.COIN_TYPE,
    account: 0,
    change: CHANGES.EXTERNAL_CHAIN,
    address: [0, 10]  // or '0-10'
  })
);

console.log('Mnemonic:', hdwallet.getMnemonic())
console.log(`Base HD Path:  m/44'/{XinFin.COIN_TYPE}'/0'/0/<address>`, '\n')

// console.log dived XinFin HDWallet information's
for (let derivation of hdwallet.getDumps(['root', 'indexes'])) {
  // console.log path, address and private_key
  console.log(`${derivation['at']['path']} ${derivation['address']} ${derivation['private-key']}`);
}

Output

Mnemonic: abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about
Base HD Path:  m/44'/{XinFin.COIN_TYPE}'/0'/0/<address>
