Address Flags

The contract source explicitly states: CREATE2 address flags: last 14 bits == 0x0044.

Decoded: 0x0044 = 0b00_0000_0100_0100

• Bit 6 → afterSwap: true ✓
• Bit 2 → afterSwapReturnsDelta: true ✓
• All other 12 bits → false ✓

Matches the hook file exactly.

Source Metadata

• verifiedSource: true — confirmed by source_meta.json ("verified": true)
• chainId: 8453 — matches chains.json for base ✓
• name: "VenaHook" — matches the on-chain contract name contract VenaHook ✓
• No proxy/implementation: source_meta.json confirms "proxy": false ✓

Properties

Property	Claimed	Verdict
dynamicFee	false	No updateDynamicLPFee() call and no lpFeeOverride return from beforeSwap (no beforeSwap at all). ✓
upgradeable	false	No proxy pattern, delegatecall, mutable implementation slot, or SELFDESTRUCT. Key addresses are immutable. ✓
requiresCustomSwapData	false	_resolveSwapper(hookData) falls back to tx.origin when hookData is empty or malformed. Swaps execute normally without hookData; NFT game effects still apply via tx.origin. ✓
vanillaSwap	false	afterSwapReturnsDelta is true — the hook takes a 1% fee from the output via poolManager.take() and returns a positive delta. This materially changes swap execution. ✓
swapAccess	"none"	The afterSwap function only checks msg.sender == address(poolManager) (standard PoolManager guard). No allowlist, governance flag, or temporal gate on swap access. ✓

Description

"Custom-accounting Uniswap v4 hook for ETH/VENA on Base. Uses afterSwap return delta (1% output fee), distributes 80% to NFT holders and 20% to treasury, and applies buy/sell NFT game logic."

All claims are substantiated by source:

• 1% fee: FEE_DIVISOR = 100 ✓
• 80% to NFT holders: HOLDER_SHARE_BPS = 8000 ✓
• 20% to treasury: TREASURY_BPS = 2000 ✓
• Buy/sell NFT game logic: _handleBuy/_handleSell mint/burn PickaxeNFT tokens ✓

No audit claims, safety guarantees, or promotional language present.

All fields are correct.
