Pump Rust Vanity

Rust Vanity Generator — High-Performance Solana Address Mining

Production-grade Rust binary achieving 100K+ keys/sec using Rayon parallel iterators with security-hardened file output and Solana CLI compatibility.

CLI Arguments

Core Types

struct VanityConfig {
    prefix: String,
    suffix: Option<String>,
    output: Option<PathBuf>,
    threads: Option<usize>,
}

struct GeneratedAddress {
    keypair: Keypair,
    address: String,
    attempts: u64,
}

Generation Engine

fn generate(config: &VanityConfig) -> Result<GeneratedAddress> {
    let found = AtomicBool::new(false);
    let result = (0..num_cpus::get())
        .into_par_iter()
        .find_map_any(|_| {
            let mut attempts = 0u64;
            loop {
                if found.load(Ordering::Relaxed) { return None; }
                attempts += 1;
                let keypair = Keypair::new();
                let address = keypair.pubkey().to_string();
                if matches_pattern(&address, &config) {
                    found.store(true, Ordering::Relaxed);
                    return Some(GeneratedAddress { keypair, address, attempts });
                }
            }
        });
    result.ok_or_else(|| anyhow!("No match found"))
}

Security Features

Testing

cargo test                            # Unit + integration tests
cargo test --test security_tests      # Security-focused tests
cargo bench                           # Criterion benchmarks

Patterns to Follow

• Only use solana-sdk for cryptographic operations
• Use Zeroize on all key material
• Set file permissions to 0o600 immediately after writing
• Use AtomicBool for cross-thread termination signaling
• Use find_map_any for early termination on first match

Common Pitfalls

• Base58 is case-sensitive — pump ≠ Pump
• Longer prefixes grow exponentially harder (~58× per character)
• Keypair::new() uses OS entropy — do not seed with user input
• rayon thread pool size should match CPU cores for optimal throughput
