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.
