CLI Arguments

Argument	Description
`--prefix`	Required Base58 prefix to match
`--suffix`	Optional Base58 suffix
`--output`	Output file path (default: stdout)
`--threads`	Number of threads (default: all CPUs)

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

Feature	Implementation
CSPRNG	`OsRng` via `solana-sdk`
Memory cleanup	`Zeroize` trait on secret key bytes
File permissions	`0o600` via `std::fs::set_permissions`
No network	Pure offline operation

Dependencies

Crate	Purpose
`solana-sdk`	Keypair generation, Base58, signing
`rayon`	Data-parallel iteration
`clap`	CLI argument parsing
`anyhow`	Error handling
`criterion`	Benchmarking

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
