Solana HFT Engine

A production high-frequency trading engine for Solana fair-launch memecoins on Pump.fun, LetsBonk, and Moonshot. Rust core for sub-millisecond execution path. Python orchestration layer for strategy + risk. Designed and operated as an internal trading system, not a product.

The hard problem in Solana memecoin sniping is propagation latency. A token launches; the entire market sees the launch within milliseconds. Whoever's first to buy at the launch price wins. The engine uses a co-located Jito-bundle submission path that bypasses normal mempool propagation, with redundant Geyser plugins for state observation and a custom RPC fan-out for transaction submission.

Wallet orchestration handles 1000+ hot wallets with automatic rotation, profit consolidation, and capital rebalancing. Each wallet has a per-token position limit; the orchestrator enforces global exposure caps even if individual wallet strategies request more.

MEV protection is built into the submission path — every snipe is bundled with a tip to a Jito validator, and the engine refuses to submit to validators that are known to leak bundles. Risk management is a separate process that holds the kill-switch and can halt the entire fleet in under 50ms.
