Rivers LaunchHook
RobinhoodRegisteredSingleton Uniswap v4 hook for Rivers protocol launch pools, managing a pre/post-graduation lifecycle. During pre-launch phases, liquidity and swaps are restricted to the pool controller. After graduation, public swaps are enabled with protocol and creator fees taken as BeforeSwapDelta/AfterSwapDelta values and a dynamic LP fee override returned from beforeSwap.
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.
Pools using it let the hook choose the swap fee instead of a fixed tier.
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.
