LaunchHook
BaseRegisteredLaunchHook is a Uniswap v4 hook on Base. Shared Uniswap v4 hook for B20 token launches that gates pool creation to a factory, permanently locks single-sided liquidity, and charges a time-decaying anti-snipe fee (split among creator, platform, and optional referrer) on every swap. Exact-output swaps are blocked while the anti-snipe surcharge is active.

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.
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.
