Overview of Uniswap

What is Uniswap?

Uniswap is a decentralized exchange (DEX) that allows users to trade cryptocurrencies directly from their wallets without the need for an intermediary. It operates on the Ethereum blockchain and uses smart contracts to facilitate automated transactions between token pairs.

• Decentralized Finance (DeFi): Uniswap is a key player in the DeFi ecosystem, providing liquidity and enabling decentralized trading.
• Automated Market Maker (AMM): Uniswap employs an AMM model, which means that trades are executed against a liquidity pool rather than a traditional order book.

How Does Uniswap Work?

Uniswap uses a unique protocol to facilitate token swaps, relying on liquidity pools and smart contracts to ensure seamless and automated trading.

• Liquidity Pools: Users can provide liquidity to Uniswap by depositing pairs of tokens into pools. These pools provide the funds needed for trades and, in return, liquidity providers earn a share of the trading fees.
• Token Swaps: When a user wants to trade one token for another, Uniswap’s smart contracts calculate the exchange rate based on the pool’s liquidity and execute the trade automatically.
• Fees: Uniswap charges a small fee for each trade, which is distributed to the liquidity providers as an incentive for supplying the liquidity.
