EVM Vanity Generator

A high-performance, multi-threaded vanity address generator for Ethereum and EVM-compatible chains.

🚀 Features

• ⚡ Multi-threaded Performance - Leverages all CPU cores for maximum speed
• 🎯 Flexible Matching - Support for prefix, suffix, or combined patterns
• 🔤 Case Sensitivity - Optional case-sensitive matching for more precise results
• 📊 Real-time Stats - Live speed monitoring and probability tracking
• 🎨 Beautiful CLI - Clean, colorful terminal output with progress indicators
• 📦 Minimal Dependencies - Only uses viem for cryptographic operations
• 🛠️ Simple Setup - Works with npx, no installation required

📥 Installation

Option 1: Direct Usage (No Installation)

npx evm-vanity-gen -p cafe

Option 2: Global Installation

npm install -g evm-vanity-gen

Then use with either command:

evm-vanity -p cafe
evmgen -p abc

Option 3: Local Development

git clone https://github.com/yourusername/evm-vanity-gen.git
cd evm-vanity-gen
pnpm install
node index.js -p 888

💻 Usage

Basic Examples

# Generate address starting with "0xcafe..."
npx evm-vanity-gen -p cafe

# Generate address ending with "...888"
npx evm-vanity-gen -s 888

# Generate address like "0xabc...999" (prefix + suffix)
npx evm-vanity-gen -p abc -s 999

# Case-sensitive matching (slower but exact)
npx evm-vanity-gen -p CaFe -c

# Use specific number of threads
npx evm-vanity-gen -p ace -t 4

🔧 CLI Options

| Option | Alias | Description | Example | |--------|-------|-------------|---------| | --prefix <str> | -p | Address prefix (hex, without 0x) | -p cafe | | --suffix <str> | -s | Address suffix (hex) | -s abc | | --case-sensitive | -c | Match case exactly (slower) | -c | | --threads <num> | -t | Number of worker threads | -t 8 | | --help | -h | Display help message | -h |

📊 Performance

Performance varies based on:

• Pattern Length: Each additional hex character increases difficulty by 16x
• CPU Cores: More threads = faster generation
• Case Sensitivity: Case-insensitive matching is ~16x faster per character

Approximate Generation Times

| Pattern | Difficulty | Avg. Time (8 cores) | |---------|-----------|---------------------| | 3 chars | 1 in 4K | < 1 second | | 4 chars | 1 in 65K | ~5-10 seconds | | 5 chars | 1 in 1M | ~1-2 minutes | | 6 chars | 1 in 16M | ~15-30 minutes | | 7 chars | 1 in 268M | ~4-8 hours |

Times are approximate and depend on hardware

🔒 Security Warning

⚠️ IMPORTANT: This tool generates cryptographically secure private keys using Node.js crypto APIs via the viem library.

Security Best Practices:

• Always verify the generated private key controls the displayed address
• Never share your private key with anyone
• Store private keys securely (hardware wallet, encrypted storage)
• Test with small amounts before using in production
• Consider using a hardware wallet for high-value accounts
