The concept discussed in this snippet revolves around creating a money market on top of the mantle layer, similar to Layer 2. This model involves using V4 hooks with a base Uniswap liquidity, allowing for increased expressiveness. By extending this idea to platforms like Compound or Aave, liquidity hooks can be added on top, enhancing the depth of capital. Through these hooks, various functionalities such as leverage daking, LST looping, and margin trading can be implemented. The analogy of a compound platform acting as a base with applications like yield strategies or other apps built on top exemplifies the versatility and potential of the concept being discussed.
