Build a token with a Uniswap v4 hook and an NFT reward distributor for the Swarm Pepe collection (SPEPE, 0x999ce0CE8C5f7661e0c74a568FfE27CEB9177bDB, Ethereum mainnet). The collection contract cannot be changed and has no transfer hooks. Minting is still open (verify onchain; totalSupply() reverts, use totalMinted()). Launch kind univ4_hook on Ethereum mainnet, paired with ETH: the launch's standard token and pool with our hook, plus our distributor and auction contracts. Deploy in the launch. No website in this job: an existing site will integrate the contracts later, so keep clean ABIs, events and the views below. No owner powers after launch, no upgradeability, no pause. Token name: OG. Symbol: OG. The launch's standard token (1,000,000,000, 18 decimals, plain transfers); "burn" in this spec means sending to 0x000000000000000000000000000000000000dEaD, counted in a public totalBurned. START FROM EXISTING CODE: this exact project was already built and accepted (build_contract_project, all checks passed) in job a38b37bd-6caa-4756-9aa2-6033c44ac713; its source is the accepted bundle https://api.imd.fun/bundles/8d918c729607f1be5c14bc1b4d2e4b162b6f121f8462e77dad3af25760b1d064. Download it and use it as the starting point; keep its logic and only fix what review finds. That job stopped at manifest only because the pool start price was missing. Pool (launch.json): Ethereum univ4_hook policy 34, paired with native ETH (currency0 = ETH, currency1 = OG), fee 12500, tickSpacing 60, opening market cap 10 ETH per policy (100,000,000 OG per ETH), initialPrice 792281625142643375935439503360000 (decimal sqrtPriceX96). When the hook acts: on every swap in this pool, taking its fee from the settled ETH deltas (beforeSwap/afterSwap with return deltas), and enforcing the launch protection below. HOOK FEE: 3.5% on every buy and every sell, always taken in ETH (from the ETH input on buys, from the ETH output on sells), computed on actual settled deltas for exact-input and exact-output swaps. Of it: 2.5% of the trade to the distributor, 1% of the trade to the team wallet 0x90738ABe9b04622Dc0b3d015a3964Cc7D1Fd1859. LAUNCH PROTECTION: open to everyone from the first block. For the first 60 minutes after the pool opens, the buy fee decays linearly from 50% to the normal 3.5%. Everything above 3.5% goes to the distributor backlog, none to the team. After minute 60: normal fees. DISTRIBUTOR (per tokenId, weighted, no loops): - An NFT earns nothing until activated. Levels and weights: L1 = 1, L2 = 2, L3 = 4. - Activation burns OG. Cumulative cost: L1 = 50,000, L2 = 150,000, L3 = 400,000 OG (upgrading pays only the difference). Costs fixed in code, no oracle. Only the current ownerOf(tokenId) can activate or upgrade. Also activation with ETH: the contract buys the exact OG amount through the pool (paying the hook fee like any buyer) and burns it. - Accrual: accPerWeight += eth * SCALE / totalWeight; pending(id) = weight[id] * accPerWeight / SCALE - debt[id]. A new activation or upgrade settles pending first and sets debt at the current accumulator, so it never earns past fees. - Level and pending ETH belong to the tokenId and travel with the NFT on any transfer or marketplace sale. - Backlog: fees that arrive while totalWeight = 0 (and the launch-protection surplus) are held and streamed into the accumulator linearly over 30 days once something is active, never paid as a windfall to the first activator. EXIT (the only way to get ETH): - No claim that keeps the NFT. To receive its pending ETH, the owner hands the NFT to the contract and is paid everything accrued on it in the same transaction. Its level is cleared and its weight leaves totalWeight. - Exit is not allowed within 24 hours after the NFT's last activation or upgrade. AUCTION: - The exited NFT is immediately listed in a Dutch auction priced in OG. - Start price = max(10x the previous auction's sale price, 500,000 OG). Exponential decay over 36 hours down to a floor of 50,000 OG; at the floor it stays listed until someone buys. - 100% of auction proceeds are burned. The buyer receives the NFT at level 0 with zero accrual and must activate it to earn. VIEWS for the existing website (also emit an event for every activation, upgrade, exit, auction listing, sale and fee split): totalWeight, active NFTs per level, pending(id), level(id), backlog left and its stream end, current auctions with live prices, last sale price, total burned, launch fee now and minutes left of the decay. TESTS (Foundry, mainnet fork): fee in ETH on both sides and both exact modes and the 2.5/1 split; launch fee decay over 60 minutes and surplus to backlog; weighted accrual and upgrade math; no retroactive rewards; backlog streaming with zero active; level and pending travelling with transfers; exit payout and the 24h lock; auction start/decay/floor and burn; reentrancy on ETH sends and ERC-721 transfers; ETH solvency and weight conservation invariants. Independent review of the economics and every contract.
