According to BlockBeats, on January 31, according to Uniswap official news, Uniswap v4 is now online, becoming the latest version of the Uniswap protocol. After code contributions from hundreds of community members, nine independent audits, the largest security competition in history, and $15.5 million in bug bounties, Uniswap v4 is now enabled on multiple chains including Ethereum, Polygon, and Arbitrum. This update makes the protocol a highly customizable developer platform. Through the "hooks" plug-in, developers can customize logic for functions such as liquidity pools, exchanges, and handling fees.
