V4rcade Fee Hook

BaseRegistered

Fee hook for the V4rcade platform. Charges an LP fee on swaps that can only be lowered (FeeCanOnlyGoDown), supports signer-authorized fee vouchers redeemed during beforeSwap, and blocks external liquidity provision. Owner-controlled via Ownable2Step with a settable signer and trusted forwarder.

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.

Can block LP withdrawals

It runs before liquidity is removed, so it can delay or refuse LP exits.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
