The problem with Uniswap V4 is that nothing builds on top of each other. And I fear it will set the DeFi industry back years with the onset of onchain clobs. From a technical standpoint- there was a one-shot take at defining "what is a dex", and everything is built as extensions of that. Obviously, there were incorrect assumptions. A hook centric framework makes it very difficult to step beyond this original definition without a rewrite of the base. Furthermore, hooks are not meant to be built on top of each other. The base is always the start, and it's flawed for an increasing set of use cases. Collaboration becomes difficult, with little to no option for re-using the work of others. Hooks are not composable with each other. Already, only 150 days after launch, you find a lot of code building outside of the core protocol: rebuilding CL logic from the ground up, inheriting only interfaces. We've seen a fraction of the changes in onchain landscape as we will see in the coming years, and already assumptions are breaking down. What do we think happens next? Without an ability to build on top of each others work, and an easy base not built on incorrect assumptions, we are positioned to miss the critical changes coming to our industry and define amms as an inferior alternatives to clobs instead of a useful extension of them. I'll die on this hill- hooks are fundamentally a constrained way to approach dex development. The adoption of hook-centric frameworks will set the amm space back just as far the chasing of a perfect lvr solution has. I advocate for a vast rejection of a hook-centric mindset for DeFi; in favor of design thesis' more directly recognizable as "money legos"; our original promise. The key is a growing framework designed for adaptability, with far less assumptions for what the future looks like. Money legos have to be inherently be role centric from a smart contract standpoint- all components being arbitrary to no constraint bakes insecurity into it's core. We have to move quickly to adopt a post- onchain clob mindset for amms: requiring a base that allows us to adopt what makes amms special and throws away what is no longer relevant. It's not long tail, it's composability maximization. Throw away your prior assumptions. Valantis.
