CLMM

Overview

An end-to-end Concentrated Liquidity Market Maker protocol on Solana. A CLMM engine written in Rust/Anchor handles tick-based liquidity, a real-time transaction indexer reconstructs on-chain state into a Postgres analytics layer, and a modern Next.js interface drives swaps and liquidity provision.

The challenge

Concentrated liquidity is the hardest AMM design to get right: liquidity lives across discrete price ticks, and the on-chain math — sqrt-price, tick crossing, per-position fee growth — has to be exact or pools leak value. Raw chain data is also unusable for a trading UI without an indexer to reconstruct positions and ticks.

What I built

• A CLMM program in Rust/Anchor implementing tick-based concentrated liquidity, sqrt-price math and per-position fee accrual.
• A real-time indexer that subscribes to on-chain transactions, rebuilds tick/position state and writes denormalized rows to Postgres.
• A Next.js trading interface for swaps, opening positions and managing liquidity ranges.
• A TypeScript client layer wrapping the on-chain program for both the indexer and the UI.

Outcome

A complete, deployed CLMM ecosystem — program, indexer and UI — running live on Vercel.
