OrketHook

ArbitrumRegistered

A Uniswap v4 hook for binary prediction market pools that requires a backend-signed VALS sigma parameter on every swap. Computes a dynamic exponential fee from trade size, liquidity, and toxic velocity, extracting it from the collateral token and forwarding it to a YieldDistributor. Tracks LP virtual balances and updates YES/NO outcome prices after each swap.

What it can do

Runs on every swap

Its code executes inside each trade in pools that use it.

Can change what you receive

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Sets its own fee

Pools using it let the hook choose the swap fee instead of a fixed tier.

Controls who can add liquidity

It checks every deposit before it goes in.
