I Sniped a Solana Token in 400ms — Here's the Full Tech Stack Sniping new tokens on Solana is an art — and sometimes, a science. Recently, I managed to snipe a Solana token in just 400 milliseconds after its liquidity pool went live. Achieving this feat required a combination of MEV (Maximal Extractable Value) techniques, optimized RPCs, and precise routing logic. In this article, I’ll break down the full tech stack I used, including Jito MEV bundles , Jupiter routing , and Helius RPC , along with practical code examples and lessons learned. The Problem: Timing is Everything Sniping a token requires executing trades immediately after liquidity is added. The challenge is twofold: Speed : You need to submit your transaction within milliseconds of the token launch. Atomicity : Your transaction must succeed entirely or fail completely — no partial executions. To solve these challenges, I leveraged Jito’s MEV bundles , which allow for atomic transaction sequencing, and Jupiter’s swap API for optimized routing.…
