Zero-Latency DeFi: Parsing Raw Solana AMM Accounts in Rust

Originally published on xroot.dev.

In high-frequency Web3 infrastructure, relying on a TypeScript SDK or a third-party pricing API means you are already too late.

If you are building an arbitrage bot, a sniper, or a real-time indexer on Solana, reading data through abstracted REST endpoints introduces hundreds of milliseconds of latency. To build institutional-grade infrastructure, you have to bypass the middleman. You need to pull the raw binary state of the Automated Market Maker (AMM) directly from the RPC node and deserialize it natively in memory.

Here is how to reverse-engineer Solana DeFi pools and parse raw account data in Rust at microsecond speed.
