  Uniswap is a decentralized exchange protocol built on the Ethereum blockchain. It allows users to trade ERC-20 tokens directly from their wallets without the need for intermediaries. Unlike traditional exchanges, Uniswap uses an automated market maker (AMM) model, where liquidity is provided by liquidity providers who deposit tokens into smart contracts. These smart contracts use mathematical formulas to determine the price of tokens based on the ratio of tokens in the liquidity pool. This means that trades can be executed instantly, and users can always buy or sell tokens at the current market price. This is different from centralized exchanges where trades are matched between buyers and sellers. Uniswap's decentralized nature also means that it is resistant to censorship and provides users with full control over their funds.

  Uniswap works by utilizing smart contracts on the Ethereum blockchain. When a user wants to make a trade, they send their tokens to a smart contract that holds a liquidity pool. This pool contains a reserve of tokens that are used to facilitate trades. The smart contract uses a mathematical formula to determine the price of tokens based on the ratio of tokens in the pool. When a trade is executed, the smart contract automatically adjusts the token ratios in the pool to reflect the new prices. This automated process ensures that the market remains efficient and that trades can be executed instantly. Unlike other decentralized exchanges, Uniswap does not rely on order books or centralized matching engines, making it more resistant to manipulation and censorship.
