PerpLandHook
EthereumRegisteredA leveraged-long protocol on a bonding curve that lets users open 2–5x ETH-collateralized long positions. The hook owns all pool liquidity, restricts LP operations to itself, gates trading on a `tradingEnabled` flag, enforces TWAP-based price gates on opens, caps per-block curve advances, and auto-liquidates undercollateralized positions inside `afterSwap`.
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.
