Slippage Fee Hook (Arbitrum)

ArbitrumRegistered

Dynamically computes LP fees before each swap based on the simulated price impact (tick difference between current and post-swap price), charging higher fees for larger swaps to reduce impermanent loss for liquidity providers. Requires pools to use dynamic fees and reverts any swap that would cause slippage exceeding 5%.
