What Is an Automated Market Maker (AMM)?
You could think of an automated market maker as a robot that’s always willing to quote you a price between two assets. Some use a simple formula like Uniswap, while Curve, Balancer and others use more complicated ones. Not only can you trade trustlessly using an AMM, but you can also become the house by providing liquidity to a liquidity pool. This allows essentially anyone to become a market maker on an exchange and earn fees for providing liquidity. AMMs have really carved out their niche in the DeFi space due to how simple and easy they are to use. Decentralizing market making this way is intrinsic to the vision of crypto.

What Is an Automated Market Maker (AMM)?
About Lesson
An automated market maker (AMM) is a type of decentralized exchange (DEX) protocol that relies on a mathematical formula to price assets. Instead of using an order book like a traditional exchange, assets are priced according to a pricing algorithm.
This formula can vary with each protocol. For example, Uniswap uses x * y = k, where x is the amount of one token in the liquidity pool, and y is the amount of the other. In this formula, k is a fixed constant, meaning the pool’s total liquidity always has to remain the same. Other AMMs will use other formulas for the specific use cases they target. The similarity between all of them, however, is that they determine the prices algorithmically. If this is a bit confusing right now, don’t worry; hopefully, it’ll all come together in the end. 
Traditional market making usually works with firms with vast resources and complex strategies. Market makers help you get a good price and tight bid-ask spread on an order book exchange like Binance. Automated market makers decentralize this process and let essentially anyone create a market on a blockchain. How exactly can they do that? Let’s read on.
