LaunchHook
BaseRegisteredShared 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
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.
Runs at pool creation
It runs when a pool is created, often to lock in that pool’s settings.
