OrketHookPrediction market hook implementing VALS (Volatility-Adjusted Liquidity System) fees. Requires a backend-signed sigma parameter per swap; fees are calculated as e^[λ*(Δx/L)*σ] and routed to share token holders via a YieldDistributor rather than to LPs. Blocks swaps when the market is resolved or disputed. Tracks LP virtual balances and updates YES/NO share token prices after each swap.

OrketHookUniswap v4 hook for binary prediction market pools. Implements VALS dynamic fees (e^[λ·(Δx/L)·σ]-1) based on trade size, liquidity, and oracle-signed toxic velocity (σ), redirecting fees to share token holders via a YieldDistributor. Blocks swaps when the market is resolved or disputed, tracks LP positions, and requires a backend-signed sigma in hookData for every swap.

OrketHookPrediction market pool hook implementing VALS (Volatility-Adjusted Liquidity Scaling) fees. Requires a backend-signed toxic-velocity parameter (σ) via ECDSA in hookData for every swap; fees are computed as e^[λ*(Δx/L)*σ]-1, captured via BeforeSwapDelta, and forwarded to a YieldDistributor for prediction market share holders.

OrketHookUniswap v4 hook for prediction market AMM pools implementing VALS fees (exponential formula e^[λ·(Δx/L)·σ]−1) captured via beforeSwap delta and distributed to shareholders. Every swap requires a valid ECDSA-signed volatility parameter from a designated signer; swaps are blocked when the market is resolved or disputed.

OrketHookPrediction 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.

OrketHookA Uniswap v4 hook for binary prediction market pools (YES/NO outcomes) that applies VALS dynamic fees — calculated as e^[λ × (Δx/L) × σ] − 1 — using ECDSA-signed off-chain sigma parameters. Fees are routed to a YieldDistributor for share holders, not LPs.

OrketHookUniswap v4 hook for prediction market pools that implements a VALS (Variable Automated Liquidity Sensitivity) fee formula. Each swap requires a signed off-chain sigma (toxic-velocity) parameter; fees are computed as e^[λ·(Δx/L)·σ]−1, captured via BeforeSwapDelta, and forwarded to a YieldDistributor rather than to LPs. Also gates swaps and liquidity on market resolution/dispute state.

TokiHookA Uniswap V4 custom curve hook implementing Pendle-style fixed-rate yield trading for Principal Tokens. Executes the full AMM swap in beforeSwap using a custom curve and returns a BeforeSwapDelta. Swaps are gated by a per-pool maturity expiry (block.timestamp) and an optional curator-controlled pause. Supports optional ERC4626 vault rehypothecation for LP yield enhancement.
