Add ShitGiftHook hook on ethereum

[hooklist-generator]

Summary

Uniswap V4 afterSwap hook for the ShitVerse meme ecosystem. On any qualifying buy (≥ 42069 SHIT) of the canonical ETH/SHIT 1% pool, rolls a 1% RNG and on win transfers 1 ether of a randomly-picked community-deposited 'art' token (ERC-20/ERC-1155 dual-surface DualToken) to tx.origin. Per-origin 24h cooldown; CEI ordering with all state writes committed before the external transfer. Pool membership gated by ShitVerseFactory.isValidToken at deposit time.

Review: hooks/ethereum/0x0f7ff748f58d16876ba71783f3a7cf2cf3f2c040.json

Contract: ShitGiftHook — verified source on Ethereum mainnet.

Address Flags

0x...c040 → lowest 14 bits = 0x0040 → only bit 6 set = afterSwap. Matches JSON and confirmed by getHookPermissions() in source.

Flags ✓

All 14 flags correct. Only afterSwap: true.

Properties ✓

• dynamicFee: false — afterSwap returns (selector, 0); no updateDynamicLPFee() call anywhere.
• upgradeable: false — no proxy pattern, no delegatecall, no mutable implementation pointer. source_meta.json confirms proxy: false.
• requiresCustomSwapData: false — hookData is ignored (bytes calldata /* hookData */). Swaps proceed normally without it.
• vanillaSwap: false — correct. afterSwap calls IERC20(art).safeTransfer(origin, 1 ether), i.e. it transfers tokens inside afterSwap, so the swap does not behave identically to a standard v4 pool.
• swapAccess: "none" — correct. No beforeSwap flag. The pool-key matching in afterSwap is pool identity verification, not swap access control.

Metadata ✓

• chainId: 1 matches chains.json for ethereum.
• name: "ShitGiftHook" matches contractName in source_meta.json and the contract definition. No promotional or endorsement language.
• verifiedSource: true matches source_meta.json.
• description accurately reflects the Solidity logic: 42069 SHIT minimum (MIN_BUY = 42069 ether), 1% RNG (DROP_CHANCE_BPS = 100), 1 ether art token transfer to tx.origin, 24h cooldown (DROP_COOLDOWN = 1 days), CEI ordering explicitly enforced in code, factory-gated deposits. No audit claims or marketing language.

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

Closing — references the abandoned hook at 0x0f7ff748F58D16876BA71783F3a7cF2Cf3f2C040 (never used, no pool initialized). The live production deploy at 0xEf2dEBE958d3d3B8Cb8Bf489961BDDf23ca20040 is in PR #582 (issue #581).

Please close — superseded by #582.

The hook at 0x0f7ff748F58D16876BA71783F3a7cF2Cf3f2C040 was deployed but never used (no pool initialized; zero on-chain interactions since deployment). It was abandoned in favor of a Future-RANDAO queue-model redesign.

The live production hook for this project is deployed at 0xEf2dEBE958d3d3B8Cb8Bf489961BDDf23ca20040 (verified on Etherscan, submitted in #581 / PR #582). Issue #579 has been closed as superseded.

Merging this PR would register a stale, never-to-be-used entry. Please close in favor of #582.

Bot review verified. ShitGiftHook at 0x0f7f... (afterSwap only, bit 6, bitmask 0x40). Description at 455/500 chars — close to limit but compliant. Properties consistent with source. LGTM.
