Add Flaunch PositionManager hook on robinhood

[hooklist-generator]

Summary

A Uniswap v4 hook that manages memecoin launches on the Flaunch platform, featuring an internal swap pool for pre-swap fee conversion, temporal gating for scheduled token launches, a BidWall for buy-side liquidity support, and fee distribution to protocol, creators, and optional referrers.

Address Flag Verification

Address suffix 0x65dc = 0110 0101 1101 1100 (binary). All 14 permission bits match the hook file exactly:

Flag	Bit	Expected	Hook File
beforeInitialize	13	true	true ✓
afterInitialize	12	false	false ✓
beforeAddLiquidity	11	false	false ✓
afterAddLiquidity	10	true	true ✓
beforeRemoveLiquidity	9	false	false ✓
afterRemoveLiquidity	8	true	true ✓
beforeSwap	7	true	true ✓
afterSwap	6	true	true ✓
beforeDonate	5	false	false ✓
afterDonate	4	true	true ✓
beforeSwapReturnsDelta	3	true	true ✓
afterSwapReturnsDelta	2	true	true ✓
afterAddLiquidityReturnsDelta	1	false	false ✓
afterRemoveLiquidityReturnsDelta	0	false	false ✓

Also confirmed against getHookPermissions() in source (dev comment: 10 0101 1101 1100 == 25DC; with bits 14-15 from the 0x65 prefix this matches 0x65DC).

Properties Verification

• dynamicFee: false ✓ — Pool is initialized with fee: 0 (zero, not the 0x800000 dynamic fee flag). _beforeSwap returns a zero fee override. No poolManager.updateDynamicLPFee() call anywhere.
• upgradeable: false ✓ — No proxy pattern, no delegatecall to a mutable implementation, no SELFDESTRUCT. Admin setters (setFlaunch, setInitialPrice) update external component contracts, not the hook itself.
• requiresCustomSwapData: false ✓ — _hookData is used only for optional referrer fee routing in _distributeReferrerFees. The temporal gate, internal swap pool, BidWall, and all core swap logic operate independently of hookData. Empty hookData does not cause revert or materially incorrect behavior.
• vanillaSwap: false ✓ — beforeSwapReturnsDelta is true: the InternalSwapPool can fill trades from fee inventory before they hit the Uniswap pool, returning a BeforeSwapDelta. afterSwapReturnsDelta is true: the hook takes swap fees. Swap execution is materially different from a standard v4 pool.
• swapAccess: "temporal" ✓ — _beforeSwap checks flaunchesAt[poolId] > block.timestamp and reverts with TokenNotFlaunched if the scheduled launch timestamp hasn't passed yet. This is a pure temporal gate (configurable per-pool at launch time).

Metadata Verification

• chainId: 4663 ✓ — Matches robinhood entry in chains.json.
• verifiedSource: true ✓ — source_meta.json confirms "verified": true.
• name: "Flaunch PositionManager" ✓ — On-chain contract name is PositionManager; "Flaunch" qualifier is substantiated throughout the source (project-level imports like @flaunch/, function flaunch(), IFlaunch, FlaunchParams, etc.). No promotional, audit, or affiliation language.
• description ✓ — All four claims are factually grounded in the Solidity logic: internal swap pool (_processInternalSwap / IInternalSwapPool), temporal gating (flaunchesAt mapping + timestamp revert), BidWall (IBidWall bidWall, bidWall.deposit()), and fee distribution to protocol/creators/referrers (_distributeFees, _distributeReferrerFees). No marketing language.

Verdict

All flags, properties, and metadata are correct. Approving.
