I Sniped a Solana Token in 400ms — Here's the Full Tech Stack Sniping tokens on Solana is a high-stakes game of speed and precision. Recently, I managed to snipe a highly anticipated token launch in just 400ms using a carefully curated tech stack. In this article, I’ll dive deep into the technical details of how I achieved this, focusing on Jito MEV bundles, Jupiter routing, and Helius RPC. I’ll also share real code snippets, practical examples, and lessons learned along the way. The Problem: Token Sniping on Solana Token sniping on Solana involves being the first to buy a token immediately after it’s listed on a decentralized exchange (DEX). The challenge lies in the speed of execution. Transactions are processed in blocks, and delays of even a few milliseconds can mean missing out entirely. To succeed, you need: Ultra-low latency : Sub-500ms response time from token launch to transaction confirmation. Optimal gas fees : Ensuring your transaction gets prioritized without overpaying.…
