For example, the real use of Uniswap V4's "hook" is an underrated trump card feature

Recently, I saved some money in Uniswap V4, so I took a hard look at Uni's hooks. A lot of people have actually told me privately that Uni didn't feel the same amazing feeling as when V4 was launched. The main reason is that the concept of "hook" itself is too abstract and has to be blamed directly.

Rather than being literally translated as a hook, a personal fool's opinion, hook should be translated as a plug-in. The hook itself is about adding something to the pool that goes beyond Uni itself. The documentation is full of emphasis on when hooks can be invoked, but most people don't really care, but rather what hooks can do.

[Examples of the use of hooks]

--For example, it allows you to build pools, such as ETH-USDT, which can only be used by certain addresses;
-- Or, it allows your pool to charge more when it's busy and less when it's free;
-- Or, it can even allow your pool to be without the X*Y=K curve (PS: I guess it was stimulated by the curve at the time).

All in all, you are free to develop all sorts of features that you need that the official Uni may never launch.
It's kind of like the Workshop on Steam, it's all officially no longer done, and it feels like someone else is free to create.
Another change is that in the past, there were only two profitable niches on Uni, LPs and traders, and the two were pocketing each other.
After V4, there is a hook, which is actually to make some script kiddies also profitable.
You write a hook and someone else can pay to use your hook when they build a pool (sell: hook: sub?). ）。
You can use 1 hook plugin per pool, but 1 set of hook plugins can be used to subscribe to an unlimited number of pools at a fairly low marginal cost.
There is a website called Hook Rank, which contains hundreds of hooks, and you can see how much money each hook makes. One of the most commonly used hooks is Flaunch, and I think developers have made over $1 million.

What is it for? Using its hook, you can create a pool of meme coins with any percentage of the pool's fees, such as 80% to your own wallet, and then 20% to buy back.

Fortunately, Trump's son didn't know that this feature was available when he sent the $Trump, otherwise he wouldn't have directed all the expenses to the future of world finance?

In addition, as the saying goes, only competitors know you best, and Pancake also decisively introduced hooks later, but instead of calling it V4 but Pancake infinity, of course, this is another story to talk about when you have time.
All in all, hooks are a lot of fun to call V4 a name.
