Automated Market Making
Automated market making, or AMM, is a mechanism used in decentralized finance to provide liquidity without the need for a traditional limit order book. Instead of matching buyers and sellers directly, AMMs use mathematical formulas to determine the price of an asset based on the ratio of tokens in a liquidity pool.
Anyone can become a liquidity provider by depositing assets into these pools, earning a share of the trading fees in return. This model has democratized liquidity provision and enabled the growth of decentralized exchanges.
However, it also introduces risks such as impermanent loss, where the value of the assets in the pool changes compared to holding them individually. AMMs have become the primary engine for trading in the DeFi ecosystem, allowing for the exchange of a vast array of digital assets.
They represent a fundamental shift in how markets are structured and accessed. As the technology matures, researchers are working on ways to improve capital efficiency and reduce the risks for providers.
