Uniswap
Uniswap is a decentralized cryptocurrency exchange (DEX) protocol built on the Ethereum blockchain that enables automated token swaps without intermediaries. It uses an automated market maker (AMM) model with liquidity pools, allowing users to trade ERC-20 tokens directly from their wallets. As a leading DeFi (Decentralized Finance) application, it facilitates permissionless and trustless trading through smart contracts.
Developers should learn Uniswap to build or integrate DeFi applications, such as trading interfaces, yield farming platforms, or liquidity management tools, as it's a foundational protocol in the Ethereum ecosystem. It's essential for creating decentralized exchanges, token launchpads, or automated trading bots that leverage its open-source smart contracts and APIs. Use cases include developing custom front-ends, analyzing on-chain data, or contributing to its governance via the UNI token.
