Example of the use of hooks--For example, it can allow you to build pools, such as ETH-USDT, which can only be used by certain specific addresses; --Alternatively, it can allow your pool to charge more handling fees during busy hours and less during idle hours; --Alternatively, it could even allow your pool to avoid the X * Y=K curve (PS: I estimate it was stimulated by the Curve at that time) 😂）。 In summary, you are free to develop various features that you need, which Uni may never officially release. It's a bit like the creative workshops on Steam, which are no longer official and allow others to freely create. Another change is that in the past, there were only two profitable ecological niches on Uni, LP and trader, and the two were mutually dependent on each other 😂。 After V4, there were hooks, which actually gave some script kids a profit margin. Write a hook so that others can pay to use your hook when building a pool (selling... hook... sub?). Each pool can use one hook plugin, but one set of hook plugins can subscribe to countless pools with a relatively low marginal cost. There is a website called Hook Rank that includes hundreds of hooks, and you can see how much money each hook has earned. Currently, Flaunch is one of the most commonly used hooks, and I believe developers have already earned over one million dollars. What is it for? By using its hook, you can create a pool for meme coins and allocate any percentage of the pool's fees, such as 80% to your wallet and 20% for repurchase. Fortunately, Trump's son didn't know that Trump had this function when he sent it to Trump. Otherwise, he would not point all the expenses to the future world finance 😂？ In addition, as the saying goes, only competitors understand you the best. Later on, Pancake decisively introduced hooks, but they were not called V4 but Pancake Infinity. Of course, this is another story. Let's talk about it when we have time. Overall, the hook is quite an interesting thing, worthy of being named V4.
