I Sniped a Solana Token in 400ms — Here's the Full Tech Stack Sniping tokens on Solana is both an art and a science. With block times hovering around 400ms, the margin for error is razor-thin. Last week, I successfully sniped a freshly launched token on Solana, and today I’m breaking down the exact tech stack and techniques I used to make it happen. This is not just a theoretical guide; I’ll share real code snippets, practical examples, and the lessons I learned along the way. The Problem: Speed and Precision Sniping a token on Solana requires two things: Speed : You need to submit transactions the instant a new token is listed. Precision : Your transaction must be prioritized over others to ensure it’s included in the block. Achieving both is no small feat. Solana’s high throughput and low block times make it incredibly competitive. To succeed, I relied on three key technologies: Jito MEV Bundles , Jupiter’s Swap API , and Helius RPC . Let’s dive into each.…
