PumpRobinHook
RobinhoodRegisteredA Uniswap v4 bonding-curve launch hook that charges a 2% WETH fee on every swap (split equally between creator and platform), escalating to 99% during a configurable anti-snipe window; the pool fee is overridden to 0% via lpFeeOverride and the hook takes fees directly via BeforeSwapDelta/AfterSwapDelta. LP positions are permanently locked — removal always reverts.
What it can do
Its code executes inside each trade in pools that use it.
It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
Pools using it let the hook choose the swap fee instead of a fixed tier.
It runs before liquidity is removed, so it can delay or refuse LP exits.
It checks every deposit before it goes in.
It runs when a pool is created, often to lock in that pool’s settings.
