Uniswap V4, the latest version of the most popular decentralized exchange (DEX) in the world, is here. It's packed with new features and improvements that make it even more powerful and user-friendly. One of the biggest new features in Uniswap V4 is custom hooks. Hooks allow developers to modify the behavior of pools in new and innovative ways. For example, hooks could be used to create time-weighted average market makers, custom oracles, and dynamic fees. Uniswap V4 also introduces a singleton model, which consolidates all pools into a single smart contract. This reduces gas costs and makes it easier to use Uniswap. Additionally, Uniswap V4 now supports native ETH trading, which means that users can swap tokens directly for ETH without having to wrap it in WETH. Overall, Uniswap V4 is a major step forward for decentralized finance (DeFi). It makes Uniswap even more flexible, efficient, and user-friendly. This will help to attract more users to DeFi and make it more mainstream.
