# CLMM

> Concentrated-liquidity AMM. Liquidity is deposited into price ranges (ticks); positions earn fees only when the price is in range.

## What it is

CLMM is Raydium's concentrated-liquidity AMM, inspired by Uniswap v3's design and adapted to Solana's account model. Liquidity providers choose a price range rather than providing across the whole curve; capital efficiency is dramatically higher for stable and correlated pairs.

**Program ID:** see [reference/program-addresses](/reference/program-addresses).

**Token-2022:** supported (with caveats documented under [`fees`](/products/clmm/fees)).
