Add StrategyHook hook on robinhood

[hooklist-generator]

Summary

A multi-strategy hook that collects a time-decaying swap fee via afterSwapReturnsDelta, splitting proceeds between an ops wallet and fee collector. Pools are owner-initialized and mapped to configurable strategies; exact-output swaps revert.

Review: hooks/robinhood/0xc8fe3570f110d092e86393c095c6998a8d5a6544.json

Address Flags

Address 0xc8fe3570f110d092e86393c095c6998a8d5a6544 — lowest 14 bits: 0x6544 & 0x3FFF = 0x2544 = 10 0101 0100 0100 binary.

All 14 flag bits match the JSON and match getHookPermissions() in the source:

• beforeInitialize = true (bit 13 = 1) ✓
• afterAddLiquidity = true (bit 10 = 1) ✓
• afterRemoveLiquidity = true (bit 8 = 1) ✓
• afterSwap = true (bit 6 = 1) ✓
• afterSwapReturnsDelta = true (bit 2 = 1) ✓
• All other flags = false ✓

Chain & Metadata

• chainId: 4663 matches chains.json entry for robinhood ✓
• name: "StrategyHook" matches source_meta.json (contractName: "StrategyHook") and the contract declaration contract StrategyHook ✓
• verifiedSource: true confirmed by source_meta.json ("verified": true) ✓
• No promotional, audit, or endorsement language in name or description ✓

Properties

• dynamicFee: false — Correct. The hook has no beforeSwap flag and never calls poolManager.updateDynamicLPFee(). Fees collected in afterSwap are an additional hook fee via afterSwapReturnsDelta, not a dynamic LP fee override.

• upgradeable: false — Correct. source_meta.json shows proxy: false. Contract is a standard BaseHook + Ownable with no proxy, delegatecall, mutable implementation pointer, or SELFDESTRUCT.

• requiresCustomSwapData: false — Correct. _afterSwap ignores the bytes calldata (hookData) parameter entirely; swaps proceed without it.

• vanillaSwap: false — Correct. afterSwapReturnsDelta is true, so this must be false per spec. Confirmed: _afterSwap returns a non-zero int128 fee delta that modifies the effective swap output.

• swapAccess: "none" — Correct. There is no beforeSwap hook. _afterSwap contains no access-control gate (no allowlist, temporal, or governance check). feeExemptSwappers only waives the fee; it does not block or gate swap execution.

Description Accuracy

"A multi-strategy hook that collects a time-decaying swap fee via afterSwapReturnsDelta, splitting proceeds between an ops wallet and fee collector. Pools are owner-initialized and mapped to configurable strategies; exact-output swaps revert."

All claims substantiated:

• Multi-strategy: mapping(uint256 => StrategyConfig) public strategies with multiple IDs ✓
• Time-decaying fee via afterSwapReturnsDelta: _feeBps() decays from startingFeeBps toward restingFeeBps based on block.timestamp - launchTimestamp, collected via int128 return in _afterSwap ✓
• Split between ops wallet and fee collector: explicit opsAmount / collectorAmount split logic ✓
• Owner-initialized pools: _beforeInitialize enforces if (sender != owner()) revert NotOwner() ✓
• Exact-output reverts: if (params.amountSpecified > 0) revert ExactOutputNotAllowed() ✓

All checks pass.
