Three years ago, Blur had a monthly trading volume of $1.43 billion, accounting for 70% of the Ethereum NFT market. Today, Blur announced it will shut down on November 12. The same founder has closed two projects in 10 days: Blast first, now Blur. The website is closing, but the contracts remain; anyone who borrowed through Blend must repay by November 12 or default. Did Blur die because of the NFT winter, or because zero fees meant zero revenue?
