HD Wallet

Easily generate secure cryptocurrency wallets with this modular, standards-compliant HD wallet engine built in C++. Whether you're learning how wallet internals work, building blockchain tools, or experimenting with key derivation and address formats, this CLI tool helps you create mnemonics, derive keys using BIP-32, and generate addresses with precision all with minimal dependencies and full control.

Features

• Create secure wallet phrases of various lengths
• Generate a full set of keys from a single phrase
• Get both public and private keys instantly
• Create addresses compatible with multiple blockchain formats
• Select from different coin types at runtime
• Use the tool entirely from your terminal
• Designed to be fast, lightweight, and easy to extend

Prerequisites

• A Linux environment (or WSL on Windows)
• A C++17-compatible compiler (e.g. g++)
• OpenSSL development libraries (libssl-dev)
• nlohmann‑json header‑only library (nlohmann‑json3-dev)
• CMake version 3.14 or higher

Setup

1. Clone the repository and navigate into the project directory:

git clone https://github.com/Roshan-1024/HD-Wallet.git
cd HD-Wallet

2. Install dependencies (for Debian/Ubuntu/WSL):

sudo apt update
sudo apt install build-essential cmake libssl-dev nlohmann-json3-dev

3. Build the project:

mkdir build
cd build
cmake ..
cmake --build .

4. Run the executable:

./bin/wallet

Running Unit Tests

To run the tests:

cd build
ctest

Or, run the test executable directly:

./bin/unit_tests

Example Output

Standards Used

• BIP-39: Mnemonic code for generating deterministic keys
• BIP-32: Hierarchical Deterministic Wallets
