Vanity Seed

A fast, multi-threaded vanity seed phrase generator for Ethereum addresses. Generate BIP39 seed phrases that produce addresses with custom patterns.

What it does

Creates random seed phrases and checks if the first derived Ethereum address (following BIP44 path m/44'/60'/0'/0/0) matches your desired pattern. Uses all available CPU cores for maximum speed.

Usage

cargo run --release

Pattern formats

• <start> - Address starts with pattern
• *<end> - Address ends with pattern
• <start>*<end> - Address starts with first pattern and ends with second

Examples

cargo run --release 0000 # Starts with '0000' 
cargo run --release *babe # Ends with 'babe' 
cargo run --release abc*123 # Starts with 'abc' and ends with '123'

Performance

• Highly optimized with SIMD-friendly operations
• Uses thread-local contexts and batch processing
• Typically processes 100K+ attempts per second on modern hardware
• Longer patterns take exponentially more time to find
