What Is a Liquidity Pool in Decentralized Finance (DeFi)?
A liquidity pool is a collection of two or more tokens locked in a smart contract on a Decentralized Exchange (DEX). It facilitates trading by providing the necessary assets for users to swap between tokens without needing a traditional buyer or seller.
Liquidity providers (LPs) deposit an equal value of both tokens and earn trading fees in return. This is the foundation of automated market makers (AMMs).
