According to Odaily, NFT marketplace KnownOrigin, which was previously acquired by eBay, has announced the closure of its on-chain market and minting functions. This decision follows significant changes in the NFT market landscape. Earlier this year, in February, eBay laid off 30% of KnownOrigin's staff, sparking concerns about the platform's future. The recent announcement confirms these concerns, as the company has decided to cease operations due to the evolving NFT market conditions.
