OrketHookUniswap v4 hook for prediction market pools (YES/NO outcome tokens) that implements VALS (Volatility-Adjusted Liquidity Sensitivity) dynamic pricing. Requires a backend-signed sigma parameter per swap to compute an exponential fee captured from the USDC collateral side and distributed to share holders via a YieldDistributor; swaps are blocked when the market is resolved or disputed.

OrketHookA Uniswap v4 hook for prediction market YES/NO pools that computes a VALS dynamic fee per swap (e^[λ·(Δx/L)·σ]−1) from a backend-signed volatility parameter, captures it via beforeSwapReturnsDelta, and routes it to a YieldDistributor rather than LPs. Swaps require a valid ECDSA-signed sigma struct in hookData.

OrketHookA Uniswap v4 hook for prediction market pools that applies a VALS (Volatile Automated Liquidity Sensitivity) fee on every swap. The fee is computed as e^[λ × (Δx/L) × σ] − 1 using a sigma value supplied via ECDSA-signed hookData, and is redirected to prediction market share holders via a YieldDistributor rather than to LPs.

OrketHookUniswap v4 hook for prediction market YES/NO pools implementing VALS (Volatility-Adjusted Liquidity Sensitivity) dynamic fees. Each swap requires a backend-signed sigma parameter; fees are computed via e^[λ*(Δx/L)*σ]−1 and extracted from the collateral token via beforeSwap delta, then routed to a YieldDistributor for share holders. Also tracks LP positions and updates market prices after each pool operation.

OrketHookA Uniswap v4 hook for prediction market pools (YES/NO share tokens) implementing a VALS formula fee: fees are computed from trade size, pool liquidity, and a signed toxic-velocity parameter (sigma) provided per-swap via hookData. Captured fees are routed to a YieldDistributor for share token holders rather than LPs. Also tracks LP virtual balances and updates pool prices for yield accounting.

OrketHookA prediction market hook for Uniswap v4 pools (YES/NO outcome shares vs collateral). Implements VALS (Volatility-Adjusted Liquidity Sensitivity) fees calculated as e^[λ*(Δx/L)*σ]-1, where σ is a per-swap toxic-velocity parameter supplied as a signed off-chain oracle message. Fees are captured from the collateral token via BeforeSwapDelta and routed to a YieldDistributor rather than to LPs.

EnhancedFeeDistributionHookV2Captures swap output fees via afterSwapReturnDelta and distributes them as a single reward token to LPs. Fees are buffered per token until a configurable threshold is met, then converted to the reward token via a nested swap on a separate pool. Uses ERC-6909 accounting and NFT-based position tracking for reward claims.
