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 perfect snipe in just 400ms from block inclusion to confirmation. Here's the exact technical breakdown of how I built this MEV (Maximal Extractable Value) sniper bot using Jito bundles, Jupiter routing, and Helius RPC optimizations. The Challenge: Why 400ms Matters Solana's 400ms block times mean traditional Ethereum-style MEV strategies won't cut it. You need: Sub-block latency (execution must finish before the next slot) Precise bundle construction (Jito bundles require exact simulation) Optimal routing (Jupiter's on-the-fly swap calculations) Tech Stack Breakdown 1. Jito MEV Bundles (The Execution Layer) Jito bundles let you guarantee transaction order by paying validators directly. Unlike Ethereum, where you compete in the public mempool, Solana bundles are private until inclusion. Key Components: Bundle Construction: Transactions must be pre-signed and ordered correctly.…
