LaunchHookV3

RobinhoodRegistered

Fee hook for ETH/token launches that withholds tiered ETH fees on buys and sells via beforeSwap and afterSwap return deltas. Applies an anti-sniper window (28% fee), a secondary window (15% fee), and a normal period (2% fee) after LP is seeded, distributing fees to a treasury and a rewards distributor.

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.

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.
