UNI

Uniswap is a decentralized exchange protocol built on Ethereum that allows users to swap tokens directly from their wallets without relying on a central intermediary. Instead of using an order book, it uses an automated market maker model, where liquidity pools and smart contract logic determine pricing and execution. This structure made Uniswap one of the most recognizable applications in DeFi and a reference point for on-chain trading infrastructure.

The protocol supports permissionless token listings, which means new assets can be traded without a traditional approval process. Liquidity providers deposit token pairs into pools and receive a share of trading fees in return, while users benefit from continuous market access and on-chain settlement. Over time, Uniswap expanded through multiple versions that improved capital efficiency, fee control, and routing mechanisms, helping it remain relevant as the DeFi landscape evolved.

Uniswap’s ecosystem position is closely tied to Ethereum and the broader multi-chain DeFi environment, where it serves as a core venue for token exchange and liquidity provision. Its governance token, UNI, is associated with protocol governance rather than direct fee claims, and the project continues to be discussed in the context of decentralized market design, smart contract-based trading, and liquidity aggregation across blockchain networks.
