最近我存了一些钱在 Uniswap V4，所以认真地研究了一下 Uni 的钩子。很多人其实私下里跟我说过，说 Uni 推出 V4 后没有感受到 V3 上线时那种惊艳感。主要是「钩子」本身这个概念就过于抽象，要直接背锅。
Hook 与其被直译为钩子，个人愚见，还不如意译为插件。钩子本身就是给池子增加一些超越 Uni 本身的功能。它的文档里连篇累牍地强调了在什么时间可以调用钩子，其实大多数人并不关心，还不如说一下钩子到底能干什么。
【钩子的用途举例】
比如说，它可以让你建的池子，例如 ETH-USDT 仅限某些特定地址才能使用；
又或者，它可以让你的池子在繁忙时多收手续费，在空闲时少收手续费；
再或者，它甚至可以让你的池子可以不用 X*Y=K 这个曲线（PS ：估计当时被 Curve 刺激到了）。
总而言之，你可以自由开发各种各样的你需要，而 Uni 官方可能永远不会推出的功能。
有点像 Steam 上的创意工坊，都是官方不再做了，让其他人自由创造的感觉。
还有一个变化是，过去 Uni 上盈利的生态位就两个，LP 和交易者，而且两者是互相掏对方兜儿。V4 之后有钩子了，其实是让一些脚本小子也有盈利位了。
你写一个钩子，别人建池子的时候可以付费使用你的钩子（卖.. 钩.. 子？）。每个池子可以用 1 个钩子插件，但是 1 套钩子插件可以给无数个池子订阅，边际成本相当低。有个网站叫 Hook Rank 里面收录了几百个钩子，能看到各种钩子赚到了多少钱。目前大家最常用的一个钩子之一 Flaunch，我看开发者已经赚到了 100 多万美金了。
它是干嘛的呢？用它的钩子，可以让你在给 meme 币创建池子的时候，把这个池子的手续费任意比例，例如 80% 指向给自己的钱包，然后 20% 用于回购。
幸好川普儿子发 $Trump 的时候不知道有这个功能，不然他还不把所有费用都指向未来世界金融？
另外，俗话说，只有竞争对手最懂你，后面 Pancake 也果断引入了钩子，只不过不叫 V4 而是称之为 Pancake infinity，当然这是另外一个故事了有空再聊。总而言之，钩子还是挺有意思的一个东西，足以冠之以 V4 之名。
