# CPMM

The Raydium SDK provides tools for creating and interacting with CPMM (Constant Product Market Maker) pools. Create pools, manage liquidity, lock LP tokens, and execute swaps, all with a few lines of code.

{% hint style="info" %}
CPMM pools use the classic x\*y=k constant product formula. For concentrated liquidity with custom price ranges, see the CLMM guide.
{% endhint %}
