I Sniped a Solana Token in 400ms — Here's the Full Tech Stack When a new Solana token launched recently, I managed to snipe it in just 400 milliseconds from transaction signing to on-chain confirmation. This wasn't luck—it was a carefully engineered system combining Jito MEV bundles, Jupiter's routing, and Helius's RPC endpoints. Here's exactly how I built it. The Architecture Breakdown My sniper bot consists of three critical components working in perfect harmony: Jito MEV Bundles (for transaction priority) Jupiter API (for optimal swap routing) Helius RPC (for ultra-low latency) Here's the sequence that happens in those 400ms: Detect new pool creation via Helius webhooks Construct swap transaction via Jupiter API Bundle and prioritize via Jito Submit and confirm Jito MEV Bundles: The Secret Weapon Jito's bundle system lets you pay for priority by including tip payments to validators. Unlike Ethereum's mempool, Solana transactions don't have a public mempool—they go directly to leaders.…
