What Is the Role of an Automated Market Maker (AMM) in a DEX?

An AMM is a protocol that manages liquidity pools and determines asset prices using a mathematical formula, typically x y = k. It replaces the traditional order book of a centralized exchange.

It allows users to trade without needing a direct counterparty, enabling permissionless listing and trading, which is the core functionality of a DEX.
