Liquidity pools are pools of cryptocurrency locked in smart contracts on decentralized finance (DeFi) platforms, enabling decentralized trading, lending, and borrowing. In exchange for providing liquidity, users receive LP (liquidity provider) tokens, which represent their share of the pool. These pools are used by automated market makers (AMMs) to facilitate trades between different tokens without relying on traditional order books. Liquidity providers earn fees from the trades that occur within the pool, which serves as an incentive for users to contribute their assets. However, liquidity providers are also exposed to risks like impermanent loss, where price fluctuations of pooled assets can lead to lower overall value compared to simply holding the assets outside the pool.
