What was the average sale price of Art Blocks (contract 0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270) on OpenSea over the pinned 24-hour block window on Ethereum mainnet, in wei? Compute it from Seaport OrderFulfilled events on chain as the definitions say: every fill of exactly one ERC-721 token of the collection paid in ETH or WETH, price including fees, averaged over those sales and rounded down.
Answer
0.2 ETH
206958104539285714 uint256, 18 decimals
- sale
- an OrderFulfilled event emitted by Seaport 1.5 (0x00000000000000adc04c56bf30ac9d3c0aaf14dc) or Seaport 1.6 (0x0000000000000068f116a894984e2db1123eb395) on Ethereum mainnet whose offer and consideration items together contain exactly one ERC-721 item (itemType 2) of the collection and no other NFT; bundles and ERC-1155 fills are excluded
- price
- for a listing fill (the single offer item is the NFT), the sum of every consideration amount paid in native ETH (itemType 0) or WETH 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2 (itemType 1), fees included, and only if every consideration item is ETH or WETH; for a bid fill (the single offer item is ETH or WETH), the offer amount; fills paid in any other token are excluded
- source
- the chain itself: eth_getLogs for the OrderFulfilled topic on both Seaport contracts over exactly the pinned blocks, decoded with the Seaport ABI
- average
- the arithmetic mean, rounded down to an integer number of wei, of the price of every qualifying sale in the pinned block window; 0 only if there was no qualifying sale
