Uniswap V4 Hooks

To implement Uniswap V4 hooks, use a base hook contract to define custom logic for dynamic fees and access control. This framework provides the necessary permission flags and callback interfaces to modify pool operations during swaps and liquidity changes.

Uniswap V4 permission flags are settings that dictate which lifecycle callbacks a hook receives, such as beforeSwap or afterSwap. They enable smart contracts to execute specific access control or dynamic fee logic when triggered by pool operations.

Use HookMiner to calculate a deterministic address for your Uniswap V4 hook by mining for the specific permission flags required. This process ensures your smart contract deploys to an address that matches the required prefix for pool attachment.

Yes, you can build a custom oracle using Uniswap V4 hooks by implementing logic within the beforeSwap and afterSwap callbacks. This allows smart contracts to capture and store price data dynamically during pool operations.

BeforeSwapDelta is a value used in Uniswap V4 hooks to calculate and return custom swap deltas. It allows developers to modify the exact token amounts exchanged during a swap operation within the beforeSwap callback.

Yes, the BaseHook abstraction supports both beforeSwap and afterSwap interactions. It provides a structured flow for smart contracts to execute custom logic before and after pool operations occur.
