UmiaHook

BaseRegistered

Singleton Uniswap v4 hook for Umia LBP (Liquidity Bootstrapping Pool) pools. Enforces full-range-only liquidity positions, maintains a TWAP oracle (ring-buffer observations written before each swap and liquidity event), and deducts a configurable protocol fee from each swap's output side via afterSwapReturnsDelta, crediting it to a per-pool fee recipient.

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.
