As daily volumes increase, the world's top NFT marketplace, OpenSea, is ready to break its own monthly sales record on Ethereum. OpenSea's $2.1 billion in nonfungible token (NFT) trading volume until January 10 is more than half the total trading volume for the entire month of August 2021, the largest month on record. According to Dune Analytics, volume reached approximately $3.5 billion in that month.
