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

When the new WEN token launched on Solana last month, I managed to snipe it in just 400ms after liquidity was added. Here's the exact technical stack that made this possible, with code samples and hard-won lessons from the frontlines of Solana MEV.

The MEV Landscape on Solana

Solana's MEV game operates at a different timescale than Ethereum. Where Ethereum block times are 12 seconds, Solana produces blocks every 400ms. This means our entire snipe workflow - from detecting liquidity to submitting transactions - needs to complete in less than one slot time.

The key components we'll use:

Jito MEV Bundles for guaranteed transaction inclusion

Jupiter API for optimal routing

Helius RPC for low-latency data

WebSocket subscriptions for real-time monitoring

The first challenge is detecting when liquidity is added.…
