Swap.io CLMM is an open-sourced concentrated liquidity market maker (CLMM) program built for the Solana ecosystem. This project is a fork of Raydium's CLMM, and while it builds upon the original design, it has been adapted and enhanced by the Swap.io team. For reference, you can review the original project at Raydium-Amm-v3.

Concentrated Liquidity Market Maker (CLMM) pools allow liquidity providers to select a specific price range at which liquidity is active for trades within a pool. This is in contrast to constant product Automated Market Maker (AMM) pools, where all liquidity is spread out on a price curve from 0 to ∞. For LPs, the CLMM design enables capital to be deployed with higher efficiency and earn increased yield from trading fees. For traders, CLMMs improve liquidity depth around the current price which translates to better prices and lower price impact on swaps. CLMM pools can be configured for pairs with different volatility.
