EggsFeeHook

RobinhoodRegistered

A Uniswap v4 hook for Eggs Launchpad pools that charges a flat fee (0.1%–5.2%) on ETH-denominated swaps: taken from the input on buys (beforeSwap) and from the output on sells (afterSwap), forwarded to a per-pool fee vault. Only exact-input swaps are permitted; exact-output swaps revert. Pool registration is restricted to a single authorized factory address.

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.

Runs at pool creation

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