Definition
Automated Market Maker (AMM) is a Decentralized Finance (DeFi) protocol that facilitates automatic Cryptocurrency trading without traditional order books.
Automated Market Makers use Liquidity Pools, which are pools of assets locked in Smart Contracts, to facilitate trading without needing buyers and sellers to be matched directly.
Additional Explanation
AMMs operate on the principles of supply and demand. Asset prices are determined by a mathematical formula that adjusts based on the ratio of assets in the Liquidity Pool.
This model enables efficient and permissionless trading while incentivizing Liquidity Providers to contribute assets to the pool.
AMMs have gained popularity within the DeFi space due to their accessibility, Decentralization, and ability to support a wide range of trading pairs.
However, they also face challenges such as Impermanent Loss and Slippage, which traders and Liquidity Providers should consider when participating in AMM-based trading.
