RobinhoodRegistered

Singleton Uniswap v4 hook for token launches that extracts a 1% protocol fee and a configurable creator fee (up to 5%) in ETH on every swap, distributing proceeds to a treasury, token creator, holder reward pool, and optional swap referrer. Only the registered factory can create pools, and all liquidity is permanently locked at launch.

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.

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.
