Add Spectra Launchpad GERRY hook on base

[hooklist-generator]

Summary

Bonding-curve memecoin launchpad that raises ETH along a linear curve, then graduates into a Uniswap V4 ETH/token pool. ERC-20 balances are mirrored as NFTs ("facets"); pool swap fees are harvested and distributed pro-rata to facet holders in ETH.

Review: hooks/base/0x4627812f40bdd47c8fa1a4daac8f40bc26ef8040.json

Address Flags ✓

0x...8040 → 0x8040 = bit 6 set → afterSwap = true. All other flag bits are 0. This matches the getHookPermissions() function in the source, which sets only p.afterSwap = true. Correct.

Properties ✓

• dynamicFee: false — _afterSwap is declared pure and returns (IHooks.afterSwap.selector, 0). No fee override, no updateDynamicLPFee(). ✓
• upgradeable: false — No proxy pattern, no delegatecall, no mutable implementation storage, no SELFDESTRUCT. ✓
• requiresCustomSwapData: false — _afterSwap ignores all parameters including the bytes calldata hookData. ✓
• vanillaSwap: true — _afterSwap is a pure no-op returning (selector, 0). NFT sync occurs in _afterTokenTransfer (ERC20 callback), but nested swap calls in _maybePoke() are guarded by if (poolManager.isUnlocked()) return;, preventing re-entrancy during a swap. Swap output amounts are not modified. ✓
• swapAccess: "none" — No beforeSwap flag; afterSwap has no access control. ✓

Metadata

• chainId: 8453 — Matches base in chains.json. ✓
• verifiedSource: true — Confirmed by source_meta.json ("verified": true). ✓
• description — Accurately describes the linear bonding-curve launchpad, graduation into a Uniswap V4 ETH/token pool, ERC-20/NFT mirroring ("facets"), and pro-rata ETH fee distribution to facet holders. ✓

Name ✗

The name field is "Spectra Launchpad GERRY". The word "GERRY" does not appear anywhere in the verified on-chain source (not the contract name, no @title NatSpec, no file paths, no imports). The Etherscan contract name is SpectraLaunch and the NatSpec reads @notice Spectra launchpad token…. "GERRY" appears to be a personal identifier appended by the submitter.

Required fix: The name must be changed to "SpectraLaunch" (the Etherscan contract name) or "Spectra Launchpad" (derived from the NatSpec @notice). The unsubstantiated " GERRY" suffix must be removed.

Review: hooks/base/0x4627812f40bdd47c8fa1a4daac8f40bc26ef8040.json

Flags

Address 0x4627812f40bdd47c8fa1a4daac8f40bc26ef8040 — lower 14 bits of 0x8040 are 0x0040 = bit 6 → afterSwap only. This matches the flags section exactly, and is confirmed by getHookPermissions() which sets only p.afterSwap = true.

Properties

• dynamicFee: false ✓ — _afterSwap is a pure stub returning (selector, 0). No lpFeeOverride, no updateDynamicLPFee. Static pool fee is POOL_FEE = 10_000.
• upgradeable: false ✓ — No proxy pattern, no delegatecall, no SELFDESTRUCT, no mutable implementation pointer.
• requiresCustomSwapData: false ✓ — _afterSwap accepts but completely ignores hookData. Swaps function normally without any hookData.
• vanillaSwap: true ✓ — The afterSwap implementation is a pure function that simply returns (IHooks.afterSwap.selector, 0). It performs no observation, no state mutation, and modifies no swap behavior. Swap executes identically to a standard v4 pool.
• swapAccess: "none" ✓ — No beforeSwap flag, no access control in the hook callbacks.

Metadata

• verifiedSource: true ✓ — Confirmed by source_meta.json ("verified": true).
• chainId: 8453 ✓ — Matches base entry in chains.json.
• name: "Spectra Launchpad" ✓ — Contract name is SpectraLaunch; NatSpec @notice says "Spectra launchpad token". The name is a reasonable label substantiated by verified source.
• description ✓ — Accurately describes the bonding-curve mechanic (_curveCost, buyFor, sell), graduation to V4 pool (_graduate), ERC-20/NFT mirroring via SpectraMirror, and fee harvesting/distribution via pokeFees/accFeesPerShareETH. No marketing, audit, or safety claims.

All fields are correct.
