A secure wallet generator for Octra blockchain written in TypeScript using Bun's native server.

• BIP39 Mnemonic Generation: Creates 12-word mnemonic phrases
• Ed25519 Cryptography: Uses TweetNaCl for secure key generation
• HD Key Derivation: Hierarchical deterministic wallet support
• Octra Address Format: Creates addresses with "oct" prefix and Base58 encoding
• Web Interface: Modern, responsive web UI
• Real-time Generation: Streaming updates during wallet creation
• Auto-save: Automatically saves generated wallets to disk
• Cross-platform Executables: Pre-built binaries for Linux, Windows, and macOS (x64 & ARM)

1. Download the latest release:

   • Go to the Releases page
   • Download the appropriate binary for your platform:
     • wallet-generator-linux-x64.tar.gz for Linux x64
     • wallet-generator-windows-x64.zip for Windows x64
     • wallet-generator-macos-x64.tar.gz for macOS Intel
     • wallet-generator-macos-arm64.tar.gz for macOS Apple Silicon

2. Extract and run:

   Linux/macOS:

   tar -xzf wallet-generator-*.tar.gz
   chmod +x wallet-generator
   # On macOS, you may need to remove quarantine flag to run unsigned binary:
   xattr -r -d com.apple.quarantine wallet-generator
   ./wallet-generator

   Windows:

   # Extract the .zip file
   .\wallet-generator.exe

3. Open your browser: Navigate to http://localhost:8888

1. Install Bun (if not already installed):

   macOS and Linux:

   curl -fsSL https://bun.sh/install | bash

   Windows:

   powershell -c "irm bun.sh/install.ps1 | iex"

   Alternative methods:

   • Homebrew (macOS): brew install bun
   • Scoop (Windows): scoop install bun
   • npm: npm install -g bun

   Verify installation: bun --version

2. Clone and install dependencies:

   git clone <repository-url>
   cd wallet-gen
   bun install

3. Build standalone executable (optional):

   bun run build

If you downloaded a pre-built executable, simply run it and navigate to http://localhost:8888.

1. Start the server:

   bun start
   # or
   bun wallet_generator.ts

2. For development with auto-reload:

   bun dev

3. Open your browser: Navigate to http://localhost:8888

1. Generate a wallet: Click "GENERATE NEW WALLET" and watch the real-time progress

2. Wallet features:

   • View mnemonic phrase, private/public keys, and address
   • Test signature functionality
   • Derive addresses for different network types
   • Auto-save wallet file to disk

• tweetnacl: Ed25519 cryptography
• bip39: BIP39 mnemonic generation and validation
• Uses Bun's built-in crypto module and HTTP server (no Express needed)
• Uses Bun's native file serving and streaming capabilities

To build a standalone executable for your current platform:

bun run build

This creates a wallet-generator executable (or wallet-generator.exe on Windows) that includes all dependencies and static assets (HTML, fonts, and images).

⚠️ IMPORTANT: This tool generates real cryptographic keys. Always:

• Keep your private keys secure
• Never share your mnemonic phrase
• Don't store wallet files on cloud services
• Use this on a secure, offline computer for production wallets

• Runtime: Bun (fast JavaScript/TypeScript runtime)
• Entropy: 128-bit cryptographically secure random generation
• Key Derivation: Custom HD path: m/345'/cointype'/network'/contract'/account'/token'/subnet'/index
• Address Format: oct + Base58(SHA256(publickey))
• Signature Algorithm: Ed25519
• Seed Derivation: PBKDF2-HMAC-SHA512 with 2048 iterations

The TypeScript version maintains full compatibility with the Python version's wallet format and cryptographic operations, but uses different libraries:

• tweetnacl instead of nacl.signing
• bip39 library instead of manual BIP39 implementation
• Bun's native HTTP server instead of Flask
• Bun's built-in crypto instead of Python's hashlib and secrets

This version runs on Bun with native HTTP server, which provides:

• Faster startup times compared to Node.js
• Built-in bundler and transpiler
• Native TypeScript support
• Better performance for HTTP servers (no Express overhead)
• Optimized streaming for real-time wallet generation
• Zero-copy file serving for static assets

The server runs on port 8888 by default. You can modify this in the wallet_generator.ts file if needed.
