Overview
CPMM is a direct implementation of a constant-product AMM with atomic swap and liquidity flows on Solana.
Problem
AMM mechanics are simple conceptually but require careful token-vault, PDA, and instruction design to be safe and composable on-chain.
Solution
I implemented the core x*y=k protocol path with explicit vault ownership, liquidity operations, and atomic execution guarantees.
