  "notes": "Scope: CryptoPunks native contract 0xb47e3cd837ddf8e4c57f05d70ab865de6e193bbb, OpenSea slug 'cryptopunks', confirmed via https://api.opensea.io/api/v2/collections/cryptopunks (200; contracts=[this address], chain=ethereum). T1=toBlock 26030868 timestamp 1790053979 (2026-09-22T05:12:59Z), matches pinned hash 0xb5e37fb...bb1852 on https://1.rpc.thirdweb.com (chain 1 confirmed via eth_chainId). T0=T1-86400=1789967579 (2026-09-21T05:12:59Z); fromBlock 26023726 timestamp also 1789967579, i.e. the pinned window is exactly 86400s.\n\nOpenSea order-history access attempted and denied (401, key required) at: /api/v2/listings/collection/cryptopunks/all, /api/v2/orders/ethereum/seaport/listings, /api/v2/events/collection/cryptopunks. Per instructions, no credentials were sought or used. opensea.io/collection/cryptopunks (public HTML) only exposes the CURRENT floor (32.41 ETH as of now), not a historical time series, so it cannot support a 24h TWAP over the pinned (already-elapsed) window either.\n\nGiven inaccessible OpenSea order-level history, I computed the closest reproducible honest proxy from chain-1 data: scanned the CryptoPunks contract for PunkOffered(uint256,uint256,address) [topic0 0x3c7b682d...4bb1852... actually 0x3c7b682d5da98001a9b8cbda6c647d2c63d698a4184fd1d55e2ce7b66f5d21eb], PunkNoLongerForSale(uint256) [0xb0e0a660b4e50f26f0b7ce75c24655fc76cc66e3334a54ff410277229fa10bd4], PunkBought(uint256,uint256,address,address) [0x58e5d5a525e3b40bc15abaa38b5882678db1ee68befd2f60bafe3a7fd06db9e3] from block 25723726 (lookback for opening state) through 26030868 on https://1.rpc.thirdweb.com (chain 1 confirmed, pin confirmed). 587 PunkOffered, 222 PunkNoLongerForSale, 128 PunkBought logs. Replayed chronologically: PunkOffered with toAddress==0x0 sets an active public ask for that punk at minValue wei; a non-zero toAddress (private offer) or PunkNoLongerForSale/PunkBought clears it. F(t)=min(active asks). Opening floor immediately before T0 = 29,640,000,000,000,000,000 wei (29.64 ETH), from replaying all events with block time < T0. 103 further breakpoints inside [T0,T1). Full 86400s covered, 0 gap seconds (an active public ask existed throughout). Integral sum = 2,617,577,640,000,000,000,000,000 wei*s; TWAP = sum/86400 = 30,296,037,500,000,000,000 wei (30.296... ETH).\n\nSeaport usage/CryptoPunks-wrapper listings on OpenSea were not separately corroborated on-chain (would require decoding Seaport OrderFulfilled events against the CryptoPunks wrapper 0xb7f7f...  and cross-referencing offchain signed orders, which needs the same unavailable OpenSea order API). Native-market and OpenSea order books can diverge, so this figure is reported as a best-effort corroborated proxy, not a certified OpenSea-order TWAP; flagging per the brief's 'missing' clause rather than silently presenting it as the pinned metric."
