OrketHook

ArbitrumRegistered

Uniswap v4 hook for binary prediction market pools implementing VALS (Volatility-Adjusted Liquidity Sensitivity) fees. Each swap requires a signed off-chain sigma value to compute an exponential fee (e^[λ·(Δx/L)·σ]−1); collected USDC fees are routed to a YieldDistributor for share holders rather than LPs. Blocks swaps and adding liquidity when the market is resolved or disputed.

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.
