uniswap-v4-hooks

To implement permissioned Uniswap v4 hooks, define permission flags for lifecycle callbacks like beforeInitialize and afterSwap, then deploy your contract with the PoolManager. This enables custom liquidity logic, dynamic fees, and specific pricing strategies across pools.

Uniswap v4 hook permission flags are boolean settings that dictate which lifecycle callbacks a hook executes. Defining these flags for callbacks like beforeInitialize or afterSwap ensures the PoolManager correctly triggers your custom dynamic fee or oracle logic.

You test Uniswap v4 hooks using Foundry by deploying your hook contract with the PoolManager and verifying callback execution in test scripts. This validates correct selectors, per-pool state, and safe integration before production deployment.

Yes, you can build dynamic fee strategies and price oracles with Uniswap v4 hooks. The hook architecture supports custom curves, TWAMM, limit orders, and oracle integrations by utilizing explicit callback signatures and per-pool state management.

This Skill provides a reusable hook template, complete callback signatures, and deployment guidance for mining. It ensures correct selector implementation and safe integration when deploying custom execution logic to Uniswap v4 pools.
