Add OnlyHooksHook hook on ethereum

[hooklist-generator]

Summary

Takes a fee (default 1%) on the output token of every swap via afterSwapReturnsDelta, routing 50% to the treasury and 50% split evenly among the trader's active creator beneficiaries per SubscriptionRegistry. Unsubscribed traders send the full creator share to treasury. Trader identity is decoded from hookData if present, otherwise falls back to tx.origin; empty hookData never reverts.

Warnings

• Submitter-proposed description rejected: exceeds 500-character limit and incorrectly describes creditToken as "for USDC" when the code accepts any ERC20 token via Currency.wrap(token). Using AI-generated description.

Address Flags

Address 0x903633d861ab705dc6a2ef91b478b9cab00f4044 → last 14 bits = 0x0044 = 68 = 0b01000100:

Bit	Flag	Expected	Hook File
6	afterSwap	true	true ✓
2	afterSwapReturnsDelta	true	true ✓
all others	—	false	false ✓

Confirmed by getHookPermissions() in source: p.afterSwap = true; p.afterSwapReturnDelta = true.

Properties

• dynamicFee: false — No beforeSwap hook, no lpFeeOverride, no updateDynamicLPFee() call. ✓
• upgradeable: false — No proxy pattern, no delegatecall, no mutable implementation storage, no SELFDESTRUCT. ✓
• requiresCustomSwapData: false — _trader() decodes hookData only if length >= 32 and address is non-zero; otherwise falls back to tx.origin. Empty hookData never causes a revert. ✓
• vanillaSwap: false — afterSwapReturnsDelta is true and the hook takes a fee from the output currency via poolManager.take() + positive return delta, materially altering swap output. Correctly false. ✓
• swapAccess: "none" — No beforeSwap flag; afterSwap contains no access control gating. ✓

Metadata

• chainId: 1 matches ethereum in chains.json. ✓
• verifiedSource: true confirmed by source_meta.json. ✓
• name: "OnlyHooksHook" matches the Solidity contract name exactly. ✓
• description accurately describes all key behaviors: 1% default fee (hookFeeBps = 100, BPS = 10,000) on the unspecified (output) token via afterSwapReturnsDelta; 50% protocol cut to treasury (protocolShareBps = 5000); creator half split evenly among activeBeneficiaries from SubscriptionRegistry; unsubscribed traders route full creator share to treasury; trader identity decoded from hookData or falls back to tx.origin; empty hookData never reverts. No promotional, audit, safety, or affiliation language. ✓

All checks pass.
