Flaunch POSM v4 (Base)
BaseRegisteredFlaunch's PositionManager is a Uniswap v4 hook that manages the full lifecycle of memecoin launches, from token creation and fair-launch phase to ongoing swaps. It incorporates an InternalSwapPool for protocol fee accumulation, a BidWall for native-token liquidity support, and a FeeDistributor that routes swap fees to creators and optional referrers encoded in hookData.
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.
It runs when someone donates tokens to the pool’s LPs.
