Confirmed by source: REQUIRED_HOOK_FLAGS = BEFORE_SWAP_FLAG | AFTER_SWAP_FLAG | BEFORE_SWAP_RETURNS_DELTA_FLAG | AFTER_SWAP_RETURNS_DELTA_FLAG.

Properties

• dynamicFee: false ✓ — beforeSwap returns 0 for lpFeeOverride; no updateDynamicLPFee() calls. The hook adjusts deltas, not LP fees.
• upgradeable: false ✓ — Uses Ownable, no proxy pattern, no delegatecall, no mutable implementation storage, no SELFDESTRUCT.
• requiresCustomSwapData: false ✓ — The hookData parameter in both beforeSwap and afterSwap is unnamed and completely ignored by the logic.
• vanillaSwap: false ✓ — beforeSwapReturnsDelta and afterSwapReturnsDelta are set and actively used to collect fees via BeforeSwapDeltaLibrary.toBeforeSwapDelta and the int128 return of afterSwap. Swap execution is materially altered.
• swapAccess: "governance" ✓ — _enabledPoolConfig() checks poolTaxConfig[poolId].enabled, a boolean flag set by the owner via setPoolTaxConfig. Disabled pools revert with PoolNotEnabled. This fits the governance classification.

Metadata

• chainId: 4663 ✓ — matches chains.json for robinhood.
• name: "LendsProtocolHook" ✓ — matches the on-chain contract name and source_meta.json.
• verifiedSource: true ✓ — source_meta.json confirms verified: true.
• description ✓ — Accurately describes: owner-configurable fee capped at 5% (MAX_TOTAL_TAX_BPS = 500, BPS_DENOMINATOR = 10_000), collected in the quote currency, distributed to up to 10 weighted recipients (MAX_RECIPIENTS = 10, FeeRecipient[]), via beforeSwap/afterSwap delta adjustments. No marketing or audit language.

All checks pass.
