Liquidity Pool
Web3 / defi
A liquidity pool is a collection of cryptocurrency funds locked in a smart contract that enables decentralized trading, lending, and other financial services without intermediaries. Users deposit equal values of two or more assets into these pools and earn a portion of transaction fees generated by traders who swap between those assets. The automated market maker (AMM) mechanism uses a mathematical formula to determine asset prices based on the ratio of tokens in the pool, allowing trades to execute instantly without waiting for counterparties. Example: Uniswap is the largest decentralized exchange operating through liquidity pools, where users deposit ETH and stablecoins like USDC into pools to earn trading fees when others execute swaps through those pools. Why it matters for DeFi: Liquidity pools eliminate the need for traditional order books and market makers, democratizing market access and allowing anyone to become a liquidity provider while earning yields on their capital.
