Automated Market Maker

Definition ∞ An Automated Market Maker, or AMM, is a type of decentralized exchange protocol that relies on mathematical formulas to price assets rather than traditional order books. These protocols pool liquidity from users to facilitate trades. AMMs automate the process of price discovery and transaction execution through smart contracts, enabling peer-to-peer trading without intermediaries.
Context ∞ Discussions around AMMs frequently center on their role in decentralized finance (DeFi) liquidity provision and the potential for impermanent loss experienced by liquidity providers. Recent developments often involve the introduction of new AMM designs aiming to improve capital efficiency, reduce slippage, or offer novel fee structures. Regulatory scrutiny also frequently targets the decentralized nature and potential for manipulation within AMM ecosystems.
