Add Flaunch PositionManager hook on ethereum

[hooklist-generator]

Summary

Uniswap v4 hook for the Flaunch token-launch platform that manages memecoin pool creation, an internal swap pool that fills fee inventory against incoming swaps, fee distribution to creators/protocol/BidWall/referrers, and TWAP oracle recording. Swaps on newly scheduled pools are time-gated until the configured launch timestamp.

All 14 flags match. Confirmed independently by getHookPermissions() in src_contracts_PositionManager.sol.

Properties

• dynamicFee: false ✓ — The pool is initialized with fee: 0 (static). _beforeSwap returns 0 for the uint24 fee slot. No updateDynamicLPFee or OVERRIDE_FEE_FLAG usage found in the hook contract.

• upgradeable: false ✓ — No delegatecall, proxy pattern, or selfdestruct found in the PositionManager. source_meta.json confirms proxy: false. Owner-settable references (initialPrice, flaunchContract) are configurability, not upgradeability.

• requiresCustomSwapData: false ✓ — hookData in _beforeSwap / _afterSwap is only used for the optional referrer-fee feature (_distributeReferrerFees). A swap with empty hookData executes normally; no revert path requires it.

• vanillaSwap: false ✓ — Correctly false: beforeSwapReturnsDelta and afterSwapReturnsDelta are both true; additionally the hook executes an internal swap (InternalSwapPool) in beforeSwap and captures fees in afterSwap, materially altering swap execution.

• swapAccess: "temporal" ✓ — _beforeSwap checks flaunchesAt[poolId] against block.timestamp and reverts with TokenNotFlaunched if the current time is before the scheduled launch. This is a classic temporal gate.

Metadata

• verifiedSource: true ✓ — Confirmed by source_meta.json ("verified": true).
• chainId: 1 ✓ — Matches Ethereum in chains.json.
• name: "Flaunch PositionManager" ✓ — contractName is PositionManager; project name "Flaunch" is substantiated throughout the source (package paths, contract comments, event names). No promotional/audit/endorsement language.
• description ✓ — Accurately describes memecoin pool creation, the internal swap pool filling fee inventory against incoming swaps, fee distribution to creators/protocol/BidWall/referrers, TWAP oracle recording, and time-gated launch scheduling — all directly verifiable in the Solidity logic.

All fields are correct. Approving.

[marktoda]

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