  "notes": "Window check: eth_chainId=0x1 and eth_getBlockByNumber(0x18d0e63) returned hash 0xbd62867ffa4704130b1dc9e6506d3b1bdd4f801257ba414a2e70cbe4eb7ce69e (timestamp 1789940423, 2026-09-20T21:40:23Z) on both https://ethereum-rpc.publicnode.com and https://rpc.flashbots.net/fast; opening block 26021178 is 2026-09-20T20:40:23Z. Floor readings taken 2026-09-21T00:14-00:20Z: OpenSea stats API floor_price 0.13 ETH (no key needed); Alchemy NFT API getFloorPrice reports OpenSea 0.13 ETH retrievedAt 2026-09-21T00:17:30Z; Blur collection page (rendered) header floor 0.13, top bid 0.10; NFTPriceFloor api-bff.nftpricefloor.com/projects/mocaverse currentFloorNative 0.13, currentFloorOrigin opensea, token 3413, listedCount 168; CoinGecko /nfts/mocaverse floor_price native 0.13. No source showed a lower active listing on any marketplace. Because the reading is after the closing block, I checked that the floor did not move across the window: NFTPriceFloor 2h floor series (end-labelled buckets, verified by matching the single on-chain sale at 19:46:23Z to the bucket labelled 20:00) reads 0.129999 ETH for 16:00-18:00Z, 0.13 for 18:00-20:00Z, 0.13 for 20:00-22:00Z (the bucket containing the whole pinned window) and 0.13 for 22:00-00:00Z; the 8h series agrees. On-chain, eth_getLogs for Transfer on 0x59325733eb952a92e069c87f0a6168b29e80627f over blocks 26020300-26021600 (about 17:45Z-22:05Z) shows exactly one transfer, token 6743 at block 26020908 (19:46:23Z) in a Seaport 1.6 sale for 0.1349001 ETH, before the window opens; no transfers or sales occurred inside the pinned window, so the 0.13 ETH listing that was the floor at 20:00Z remained the floor through the closing block. The 0.129999 to 0.13 step earlier in the evening was an off-chain listing cancel/reprice and predates the window. Answer: 0.13 ETH = 130000000000000000 wei."
