  "notes": "Closing block 26021474 verified on two operators (rpc.flashbots.net/fast and ethereum-rpc.publicnode.com): eth_chainId 0x1, hash 0x57ff11be...e4397, timestamp 1789940411 = 2026-09-20T21:40:11Z. Read at ~22:50-23:05Z on 2026-09-20 (about 70-85 min after the closing block). The live floor at read time was 0.4742 ETH, but three bots (#8037 maker 0xb5479d53..., #6661 maker 0xbd726bfb..., #7196 maker 0x26c97200...) relist on Blur every ~20 s undercutting each other by 0.0000001-0.0001 ETH, so the floor at the closing block had to be reconstructed. Method: OpenSea GraphQL (gql.opensea.io, operations CollectionItemsListQuery sorted PRICE ASC, UseItemActivityQuery and UseCollectionActivityQuery with activityTypes LISTING/SALE, paginated with 'after') gave the full listing event stream for the collection from 21:08Z to 22:55Z plus per-token histories for the six cheapest tokens. At 21:40:11Z the lowest listing whose most recent relist was at or before that instant was Moonbirds #8037 at 0.4757507 ETH on Blur (listed 21:39:54.175Z, next relist 21:40:55Z); next were #6661 at 0.4757508 ETH (21:40:06.610Z) and #7196 at 0.4757563 ETH (21:36:50Z). No other token was listed below 0.479998 ETH (#5356 Blur, #4765 OpenSea) at that time, and there were no Moonbirds sales between 21:08Z and 22:55Z, so nothing cheaper left the book. Cross-checks: nftpricefloor.com (api-bff.nftpricefloor.com, 2h chart) shows the floor at 0.4778417 ETH for the 20:00Z bucket and 0.4754197 ETH for the 22:00Z bucket, bracketing 0.4757507; Alchemy getFloorPrice (openSea) read 0.4742369 ETH at 22:50:21Z, matching OpenSea's live floor at that moment. Blur's own API (core-api.prod.blur.io) is behind a bot challenge and could not be read directly. Answer = 0.4757507 ETH = 475750700000000000 wei."
