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

When a new Solana token launched recently, I managed to snipe it in just 400 milliseconds from transaction signing to on-chain confirmation. This wasn't luck—it was a carefully engineered system combining Jito MEV bundles, Jupiter's routing, and Helius's RPC endpoints. Here's exactly how I built it.

The Architecture Breakdown

My sniper bot consists of three critical components working in perfect harmony:

Jito MEV Bundles (for transaction priority)

Jupiter API (for optimal swap routing)

Helius RPC (for ultra-low latency)

Here's the sequence that happens in those 400ms:

Detect new pool creation via Helius webhooks

Construct swap transaction via Jupiter API

Bundle and prioritize via Jito

Submit and confirm

Jito MEV Bundles: The Secret Weapon

Jito's bundle system lets you pay for priority by including tip payments to validators. Unlike Ethereum's mempool, Solana transactions don't have a public mempool—they go directly to leaders.…
