I Sniped a Solana Token in 400ms — Here's the Full Tech Stack When Solana's latest meme token dropped last week, I executed a snipe in just 400ms from block inclusion to successful arb. Here's the exact technical breakdown of how I built this system, covering Jito MEV bundles, Jupiter's routing API, and Helius RPC optimizations. The Core Architecture My sniper bot follows a 4-stage pipeline: Event Detection (100ms): Helius webhooks for new pool creations Arb Calculation (150ms): Jupiter API for optimal routes Bundle Construction (50ms): Jito's Bundle API formatting Execution (100ms): Priority RPC submission Total latency: 400ms (measured via Traceroute and local timestamp diffs) 1. Event Detection with Helius Helius' webhook system provides 200-300ms faster pool detection than polling public RPCs.…
