What Is the Role of an Automated Market Maker (AMM) in a DEX for Perpetual Futures?
An AMM replaces the traditional order book and market maker with a liquidity pool and a mathematical formula. For perpetual futures, the AMM calculates the synthetic price, manages the funding rate mechanism, and facilitates the leveraged trades.
Users trade against the pool, which is funded by liquidity providers. The AMM smart contract ensures continuous liquidity and automated price discovery.
