Add Unigen Hook hook on ethereum

[hooklist-generator]

Summary

A Uniswap v4 hook for an ETH/UGEN pool that queues NFT mints for qualifying buyers via commit-reveal entropy in afterSwap. Applies a dynamic LP fee override (1 bps) for Tier-S wallet-age holders in beforeSwap, and includes a governance-controlled whitelist gate for the launch window.

Review: hooks/ethereum/0x66213c92f0a000a0e0dc21ad7faeb4cf528850c0.json

Contract: UnigenHook (source verified on Etherscan)

Flags

Address 0x...50c0: lowest 14 bits = 0x10C0 (01 0000 1100 0000).

Bit	Flag	Address	File
12	afterInitialize	✅ true	true
7	beforeSwap	✅ true	true
6	afterSwap	✅ true	true
all others	false	✅	false

All 14 flags match the bitmask and getHookPermissions().

Properties

• dynamicFee: true ✅ — Pool is initialized with LPFeeLibrary.DYNAMIC_FEE_FLAG and poolManager.updateDynamicLPFee() is called in _afterInitialize. _beforeSwap returns TIER_S_FEE | LPFeeLibrary.OVERRIDE_FEE_FLAG for Tier-S wallets.

• upgradeable: false ✅ — No proxy pattern, no delegatecall, no mutable implementation storage, not in source_meta.json proxy field ("proxy": false).

• requiresCustomSwapData: false ✅ — _resolveBuyer() falls back to tx.origin when hookData is absent or malformed. Swaps succeed without hookData; the only consequence is that NFT minting targets tx.origin instead of an explicitly encoded recipient.

• vanillaSwap: false ✅ — Correct; dynamicFee is true, which mandates vanillaSwap: false.

• swapAccess: "governance" ✅ — _beforeSwap reverts with NotWhitelisted() unless tx.origin is in whitelist, controlled by the whitelistEnabled boolean flag toggled by admin via setWhitelistEnabled(). This is a governance-controlled boolean flag pattern.

Metadata

• chainId: 1 ✅ — Ethereum mainnet.
• verifiedSource: true ✅ — source_meta.json confirms "verified": true.
• name: "Unigen Hook" ✅ — Matches contract name UnigenHook; no promotional/endorsement language.
• description ✅ — Accurately describes the commit-reveal NFT mint queue in afterSwap, the 1 bps dynamic fee override for Tier-S wallets in beforeSwap, and the governance-controlled whitelist launch gate. All claims are substantiated by the Solidity source.

All checks pass.
