OrketHook

ArbitrumRegistered

Prediction market hook implementing VALS (Volatility-Adjusted Liquidity Sensitivity) fees for YES/NO share token pools. Every swap requires a signed sigma parameter in hookData; the hook computes an exponential fee from trade size, liquidity, and the signed toxic-velocity value, takes the fee from the USDC (collateral) side via BeforeSwapDelta, and distributes it to share token holders through a YieldDistributor contract. Swaps are blocked when the market is resolved or disputed.

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.

Safety report

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.
iRestricted swapsSwap access: governance. Not everyone can trade every pool.
