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

Sniping tokens on Solana is a high-stakes game where milliseconds matter. Recently, I managed to snipe a trending token on Solana in just 400ms. In this post, I’ll break down the technical stack that made this possible, focusing on Jito MEV bundles , Jupiter routing , and Helius RPC . I’ll share real code snippets, lessons learned, and specific numbers to help you understand how it all works.

The Challenge: Speed and Precision

Sniping tokens on Solana involves executing a buy transaction as soon as a token launches. This requires:

Extremely fast execution : Milliseconds can separate success from failure.

MEV (Miner Extractable Value) : Competing with bots and traders for priority.

Optimal routing : Finding the best price and liquidity pool for the token.

Achieving this requires a carefully orchestrated tech stack. Here’s how I did it.
