I Sniped a Solana Token in 400ms — Here's the Full Tech Stack When a hot new token launches on Solana, the race to snipe it is measured in milliseconds. After months of testing and optimization, I successfully sniped a trending token in just 400ms from block inclusion. Here's exactly how I built the system, the technical tradeoffs, and the key lessons learned. The Core Challenge: Solana's Speed Problem Solana's 400ms block times create an extreme environment for sniping. Unlike Ethereum where you have ~12 seconds, on Solana you need: Detection (spotting the new pool) Simulation (ensuring profitable trade) Execution (getting into the next block) All in less time than a human eye blink. The Tech Stack That Made It Possible 1. Jito MEV Bundles (The Execution Layer) Jito's bundle system lets you specify transactions that must be included together atomically.…
