What Is an Automated Market Maker (AMM) and How Does It Facilitate Trading on a DEX?
An Automated Market Maker (AMM) is the underlying protocol that powers most decentralized exchanges (DEXs), replacing the traditional order book used by CEXs. Instead of matching buyers and sellers, an AMM allows users to trade against a pool of tokens, known as a liquidity pool.
The price is determined algorithmically by a formula based on the ratio of the two assets in the pool. By providing liquidity to these pools, users can earn fees from the trades that occur within them.
