CoinGecko 0.13 ETH is ~6.7% higher: CoinGecko aggregates multiple venues on a slower refresh while OpenSea stats tracks its own live orderbook minute-to-minute (drift of ~0.000008 ETH in 3.5 min observed); on-window sales (0.114-0.35 ETH) bracket both. Stats floor vs best-listing price differ ~0.008%, consistent with sub-minute listing updates.\n\nOn-chain sales cross-check (pinned blocks 26021228-26028374, closing hash verified 0x91f3...4643, block time 20:50:23Z; endpoints rpc.flashbots.net/fast + rpc.mevblocker.io/fast + ethereum-rpc.publicnode.com): 27 Cool Cats Transfer logs in 11 txs; 21 Seaport OrderFulfilled sales decoded (NFT in offer => payment in consideration; accepted bids => WETH in offer, NFT in consideration).
