Uniswap v4 launches with hooks and a singleton pool contract

Uniswap Labs/Uniswap v4

Uniswap v4 went live on Ethereum and nine other networks after nine audits, a $2.35M security competition, and a $15.5M bug bounty with no critical bugs found. Hooks (custom logic plug-ins) turn the protocol into a developer platform; a singleton contract cuts gas costs. Over 150 hooks were built at launch.

• Hooks enable dynamic fees, custom swap logic, and automated liquidity management; over 150 live at launch.
• Singleton contract holding all pools reduces gas by up to 99.99% for pool creation versus v3.
• Nine independent audits, $2.35M security competition, $15.5M bug bounty; no critical issues found.
• Live on Ethereum plus nine other networks; developer platform unlocks novel trading and LP strategies.
