I Sniped a Solana Token in 400ms — Here's the Full Tech Stack

When Solana's new token $XYZ launched last week, I managed to snipe it in just 400ms using a custom MEV (Maximal Extractable Value) setup. Here's exactly how I built the system, the mistakes I made along the way, and the optimizations that got me sub-half-second execution.

The Core Components

Jito MEV Bundles – For priority execution

Jupiter Swap API – For optimal routing

Helius RPC – For low-latency data

Rust + Anchor – For on-chain logic

Custom Frontrunning Bot – Written in TypeScript

1. Jito MEV Bundles: Bypassing the Queue

Jito’s bundles allow you to submit multiple transactions as an atomic unit, ensuring your snipe executes before others.…
