As a decentralized and open-source platform, Uniswap provides all users easy access to the crypto market. At Uniswap, there is no “governing body” that will set limits on the maximum amount of or in which companies you want to invest. Uniswap seeks to eliminate traditional "order book" models in transactions that are currently present in centralized cryptocurrencies. As an alternative, Uniswap uses AMM - the concept of "automated market maker". Centralized exchange offices operate in a way that connects sellers and buyers and charges a fee for this service. The AMM trading concept presented by Uniswap is done via a liquidity pool.  For example, when the user instructs the smart contract to perform a trade, the contract sends their tokens, such as ETH, to the liquidity pool. A mathematical formula then decides how many tokens from the other side of the pair — for example, USDT — they should receive in return. An additional advantage of Uniswap lies in security. In decentralized exchange offices, customers buy or sell cryptocurrencies with the help of smart contracts through their wallets.
