CustomHook

ArbitrumRegisteredLaunch a pool with this hook

OTC-style hook that intercepts swaps in a single direction (SELLABLE_TOKEN → BUYABLE_TOKEN only), pricing them via an external oracle and settling output from a vault rather than AMM liquidity. Liquidity addition is restricted to whitelisted addresses; accumulated sold tokens can be burned by the owner.

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.

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.
