[hooklist-generator]

Summary

A Uniswap v4 hook that queues NFT mints for qualifying ETH-to-UGEN buyers in afterSwap and applies a reduced 1 bps fee override in beforeSwap for Tier-S wallet-age holders. Includes an admin-controlled whitelist gate for launch-window anti-sniper protection.

Address Flags

Address ends in 0xd0c0 = 1101 0000 1100 0000 binary. Lower 14 bits:

• bit 12 (afterInitialize) = 1 ✓
• bit 7 (beforeSwap) = 1 ✓
• bit 6 (afterSwap) = 1 ✓
• All other bits = 0 ✓

Confirmed by getHookPermissions() in source — all flags match exactly.

Properties

• dynamicFee: true — _afterInitialize calls poolManager.updateDynamicLPFee(key, DEFAULT_LP_FEE) to set the initial 1% fee, and _beforeSwap returns TIER_S_FEE | LPFeeLibrary.OVERRIDE_FEE_FLAG (1 bps) for tier-S wallet-age holders. ✓
• upgradeable: false — No proxy patterns, delegatecall, mutable implementation storage, or SELFDESTRUCT. ✓
• requiresCustomSwapData: false — _resolveBuyer falls back to tx.origin when hookData.length != 32. Swaps execute normally without hookData (no NFT queue to a custom address, but no revert). ✓
• vanillaSwap: false — dynamicFee is true and the fee can be overridden per-swap. ✓
• swapAccess: "governance" — _beforeSwap gates on whitelistEnabled (a boolean set by admin via setWhitelistEnabled()). This is the governance pattern. ✓

Metadata

• verifiedSource: true — Confirmed by source_meta.json. ✓
• chainId: 1 — Matches ethereum in chains.json. ✓
• name: "UnigenHook" — Matches contract name and NatSpec @title. No promotional or endorsement language. ✓
• description — Accurately describes the afterSwap NFT queueing mechanism, the 1 bps fee override for tier-S holders, and the admin-controlled whitelist gate. All claims are substantiated by the Solidity logic. No audit claims, safety guarantees, or marketing language. ✓

All fields verified against on-chain source. No issues found.
