Website: https://hdwallet.io
Generator: https://hdwallet.online
Source Code: https://github.com/hdwallet-io/hdwallet.js
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.

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

Introducing Python-HDWallet-V3 & Integration of XinFin (XDC) Wallet Protocol

Meheret Tesfaye — Fri, 31 Jan 2025 12:46:08 +0000

Hierarchical Deterministic (HD) Wallet

Website: https://hdwallet.io
Documentation: https://hdwallet.readthedocs.io
Source-Code: https://github.com/hdwallet-io/python-hdwallet
Manual: https://talonlab.gitbook.io/hdwallet/manual

Overview

The HDWallet Project delivers a unified solution for generating Hierarchical Deterministic Wallets compatible with 200+ cryptocurrency protocols. By integrating diverse cryptographic standards including entropy generation methods, mnemonic systems, elliptic curve algorithms (ECC), HD derivation paths, and address formats HDWallet streamlines secure multi-asset management. Designed for developers and users alike, it offers three interfaces: a command-line tool (CLI), an offline desktop application, and a web-based platform, ensuring flexibility across security and usability needs.

Introduction

The fragmented cryptocurrency ecosystem requires users to manage multiple wallets, each adhering to distinct protocols. This complexity increases security risks and operational inefficiencies. HDWallet addresses these challenges by unifying key management under a single, deterministic framework. Starting from a master seed, HDWallet generates hierarchical keys and addresses for diverse blockchain networks, enabling users to securely manage thousands of assets through one platform.

Core Innovation

Hierarchical Deterministic (HD) Structure: Rooted in BIP32, HDWallet derives all keys and addresses from a single master seed. Users back up only the seed (via a mnemonic phrase) to restore entire wallets, reducing key management complexity.

Why HDWallet Matters

Complete Privacy & Autonomy

Most wallets today are online or custodial, meaning they can be traced or even locked by third parties. HDWallet is designed to operate fully offline, ensuring no IP logs, no forced KYC, and no external oversight—giving you control over your keys and transactions.

Unlimited Address Generation

Generate as many addresses as you need, for as many blockchains as you want. Keep your holdings as decentralized and private as possible with streamlined address management.

Open‑Source & Community‑Driven

HDWallet’s codebase is publicly available, reflecting our commitment to transparency. We welcome contributions from developers, security researchers, and community members to help us improve and evolve.

How It Works

The HDWallet structure begins with Master Entropy, which is derived from a chosen Strength level. This entropy serves as the core randomness for generating the master keys. In this system, Master Entropy can be either generated from scratch or derived from a Master Mnemonic phrase. This two-way conversion allows users to either create entropy first or start with a mnemonic phrase, depending on their preference or specific use case. The Master Mnemonic, a human-readable representation of entropy, is generated using a specific word list that varies by Language. This mnemonic provides users with a convenient way to back up their wallets.

Once a Master Mnemonic is defined, it can also be converted back into Entropy for further cryptographic operations. The mnemonic-derived entropy is then transformed into a Master Seed, forming the foundation of the HD wallet’s hierarchical key structure. This seed is used to derive the Master Node (m/), a root entity from which all private and public keys are subsequently derived. The Root Extended (X) Private Key and Root Extended (X) Public Key are generated from this master node, forming the primary keys in the hierarchical structure.

Following the root, Child Keys (m/*) are derived from the Root Extended Private Key and, for non-hardened keys, the Root Extended Public Key. These child keys can be extended into additional layers, allowing for an almost infinite number of addressable accounts. The Extended (X) Private Key and Extended (X) Public Key are produced at each hierarchical level to support derivation paths that comply with standards like BIP32 and BIP44.

The Private Key can be converted into Wallet Import Format (WIF), which offers compatibility with various wallet applications. The Public Key derived from the private key enables the generation of the final Address the unique identifier for cryptocurrency transactions. This systematic structure of key derivation ensures that HDWallet can securely manage a vast array of addresses and keys, reducing complexity and maintaining compatibility with multiple blockchain protocols.
