As shown in the graph below of total NFT sales and traders, the Worldwide Asset eXchange (WAX), Polygon, and Flow are formidable competitors. So far in 2021, every third trader has used Flow, and every fourth trader has used WAX, despite the fact that Ethereum has accounted for nearly 90 percent of total sales this year. Although WAX only accounted for around $100 million in sales in 2021 (slightly more than 1%), its website claims that it is backed by a number of top-tier companies, including Google, Atari, Funko, Topps, and others.
