AccessControlDynamicFeeHookV4
EthereumRegisteredA Uniswap v4 hook that restricts liquidity provision to an owner-managed allowlist, applies asymmetric directional dynamic LP fees (separate rates for zeroForOne vs oneForZero), enforces configurable sqrtPrice bounds (reverting swaps that push the pool outside [min, max]), and optionally charges an additional hook fee taken from swappers via the afterSwapReturnsDelta mechanism.

What it can do
Runs code on every swap
Its code executes inside each trade in pools that use it.
Can take tokens from swaps
It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
Sets its own swap fee
Pools using it let the hook choose the swap fee instead of a fixed tier.
Gates who can add liquidity
It checks every deposit before it goes in.
