What it is

CPMM is Raydium’s standard constant-product AMM. It is the successor to AMM v4 and has no OpenBook dependency, lower gas, first-class Token-2022 support (including transfer-fee tokens), and a cleaner account layout. Program ID: see reference/program-addresses. Token-2022: supported, including transfer-fee, permanent delegate, and default-account-state extensions. See algorithms/token-2022-transfer-fees for how transfer fees affect swap math.
