# Liquidity pools There are two major types of DEXes - order book and AMM (Automated Market Maker). All AMM DEXes, including WingRiders, have liquidity pools where a function determines the exchange rate between the assets. There are two commonly used functions for pools with two assets: a Constant product market maker and a Stableswap one. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
