What is liquidity pool?
A liquidity pool is a collection of tokens in Uniswap created by liquidity providers, receiving rewards in the form of transaction fees. Traders use these pools to make cryptocurrency transactions.
Uniswap supports smart contracts for Ethereum and various ERC20 tokens, based on an “automated market maker” design. When a user makes a transaction, tokens are immediately transferred from the pool.
Users have the ability to create new trading pairs in a new liquidity pool for tokens without paying any fees (except Ethereum gas fees).
