A Uniswap v4 hook for the Momo token launch platform that collects protocol fees on swaps in registered token pools. It applies a configurable base fee (default 1%) and a higher anti-snipe tax (default 7%) on buys within the first 30 blocks after a token's launch, with collected fees claimable by the token creator.

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.
