A swap pool is a type of liquidity pool used in decentralized finance (DeFi) platforms. In a swap pool, users can deposit different cryptocurrencies or tokens, which are then used to facilitate the exchange of these assets among users in a decentralized manner. Users can swap one token for another by utilizing the liquidity provided by the pool, with automated market-making algorithms helping to determine exchange rates based on supply and demand. Swap pools are a key component of decentralized exchanges and other DeFi platforms, enabling users to trade assets without relying on centralized intermediaries.
