The protocol facilitates automated transactions between cryptocurrency tokens on the Ethereum blockchain through the use of smart contracts.

How UNISWAP is used?
As of October 2020, Uniswap was estimated to be the largest decentralized exchange and the fourth-largest cryptocurrency exchange overall by daily trading volume. In March 2021, Uniswap was generating fees of approximately US$2–3 million daily for the liquidity providers who facilitate liquid markets for the cryptocurrencies being exchanged
Uniswap uses liquidity pools rather than serving as market maker, also in contrast to centralized exchanges, with an aim to create more efficient markets. Individuals and bots—termed "liquidity providers"—provide liquidity to the exchange by adding a pair of tokens to a smart contract which can be bought and sold by other users. In return, liquidity providers are given a percentage of the trading fees earned for that trading pair. For each trade a certain amount of tokens are removed from the pool for an amount of the other token, thereby changing the price. No fees are required to list tokens which allows a large amount of Ethereum tokens to be accessible and no registration is required for users. Uniswap's code can also be forked to create new exchanges, similar to how forks occur with open-source cryptocurrencies.
