Add Flaunch PositionManager hook on unichain

[hooklist-generator]

Summary

Flaunch's core Uniswap v4 hook that manages memecoin pool launches with optional scheduled flaunch timestamps, runs an internal swap pool to fill swaps from fee inventory before hitting the Uniswap pool, captures and distributes swap fees to LPs and optional referrers via hookData, and integrates a bid wall mechanism.

Properties

• dynamicFee: false ✓ — The pool is initialized with fee: 0 (not DYNAMIC_FEE_FLAG). The _beforeSwap return's third value (fee override) is not explicitly set (returns 0). Fees are captured via afterSwapReturnsDelta and the FeeDistributor's _captureSwapFees, not via Uniswap's native dynamic fee mechanism. No updateDynamicLPFee() calls found.

• upgradeable: false ✓ — Regular non-upgradeable contract. source_meta.json confirms proxy: false. No proxy patterns, delegatecall, or SELFDESTRUCT.

• requiresCustomSwapData: false ✓ — hookData is used solely for optional referrer fees. _distributeReferrerFees() has an early return at if (_hookData.length == 0). Swaps work correctly without hookData.

• vanillaSwap: false ✓ — Correctly false: beforeSwapReturnsDelta and afterSwapReturnsDelta are both true, and the hook materially changes swap execution via the internal swap pool (_processInternalSwap) and fee capture.

• swapAccess: "temporal" ✓ — _beforeSwap checks flaunchesAt[poolId] against block.timestamp and reverts with TokenNotFlaunched if the scheduled timestamp has not yet passed. This is temporal gating.

Metadata

• chainId: 130 ✓ — Matches unichain in chains.json.
• verifiedSource: true ✓ — source_meta.json confirms verified: true.
• name: "Flaunch PositionManager" ✓ — Contract is PositionManager in src/contracts/PositionManager.sol; the "Flaunch" qualifier is substantiated by the @flaunch import namespace throughout the source. No promotional or endorsement language.
• description ✓ — Every claim is verifiable in the Solidity logic:
  • Memecoin pool launches → flaunch() function
  • Scheduled flaunch timestamps → flaunchesAt mapping, _params.flaunchAt > block.timestamp
  • Internal swap pool fills → _processInternalSwap() / internalSwapPool.internalSwap()
  • Fee distribution to LPs → _distributeFees(), _allocateFees()
  • Optional referrers via hookData → _distributeReferrerFees() with hookData decode
  • Bid wall mechanism → bidWall.deposit(), bidWall.checkStalePosition()

No marketing language, safety claims, or audit language present.

Verdict

All flags, properties, and metadata are correct and consistent with the on-chain source code.

Bot review verified. Flaunch PositionManager (unichain). Full lifecycle hook: beforeInitialize, afterAdd/RemoveLiquidity, before/afterSwap (+returnsDelta), afterDonate. LGTM.
