# Liquidity Pool For a coin pair, a liquidity pool can be created by anyone in Crescent DEX, where the liquidity pool is to reserve the amount of two different coins of the coin pair. ![Liquidity pool (LP) for a coin pair and LP providers](/files/sy8TsKY04kzGzs8MDDv6) Users can deposit a pair of coins into the pool so that those users become liquidity providers. A liquidity provider can be anyone who provides liquidity by depositing reserve coins into the pool. In Crescent DEX, a liquidity pool takes a role of automated market maker (AMM) by utilizing CPM (Constant Product Model) to calculate available liquidity. The pool price is defined as the ratio of the number of the quote coins and the number of the base coins in the pool. For the coin pair `A-B`, the pool price is the number of coin `B` divided by the number of coin `A` in the pool. Crescent DEX will support multiple liquidity pools for a given coin pair with introducing later ranged pools. --- # 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.
