Uniswap

Uniswap is a family of permissionless decentralized exchange protocols for trading ERC-20 tokens through smart contracts rather than a custodial order book. Its major versions introduced constant-product pools, concentrated liquidity, flexible fee tiers, hooks, and router systems that connect users with liquidity across Ethereum and other supported networks. Coverage should examine protocol releases, governance, contract security, liquidity-provider economics, interfaces, routing, integrations, and changes to pool behavior. UNI as an asset, Uniswap Labs as a company, and individual versions such as Uniswap V3 or V4 retain separate tags when their own token, corporate, or version-specific features are central.
