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

When Solana's latest meme token dropped, I executed a successful snipe in just 400 milliseconds. Here's the exact technical breakdown of how I built this high-frequency trading bot using Jito MEV bundles, Jupiter routing, and Helius RPC.

The Challenge: Solana’s Speed Problem

Solana’s average block time is ~400ms, but retail traders often experience much slower execution due to RPC latency and sandwich attacks. To compete, I needed:

Sub-500ms execution from seeing the token to confirmed trade

MEV protection to avoid frontrunning

Optimal routing for best price execution

The Stack That Made It Possible

1. Jito MEV Bundles (The Execution Layer)

Jito bundles allow you to submit multiple transactions atomically, ensuring your snipe isn’t sandwiched.…
