ArbitrumRegistered

A Uniswap v4 hook for binary prediction market (YES/NO outcome) pools implementing a VALS dynamic fee formula (e^[λ*(Δx/L)*σ]-1). Every swap requires a backend-signed sigma parameter; fees are captured from the collateral token and distributed to share holders via a YieldDistributor. Also tracks LP virtual balances and feeds pool prices back to the prediction market.

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.

Sets its own swap fee

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

Gates who can add liquidity

It checks every deposit before it goes in.

Automated checks, not an audit
✓Not upgradeableNo proxy pattern found: the code is fixed.
✓No owner foundNo owner() function: nobody has an admin switch (as far as the standard check goes).
✓Listed in Uniswap’s hook registryRegistered with Uniswap Labs (a listing, not a security review).
✓Source code publishedThe code on the block explorer matches what's deployed (contract: OrketHook).
iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
