Six skins, one per blockchain, have been minted on Nov 18 2011 to celebrate the release of Minecraft, the world’s largest selling video game. Each skin features the logo of the blockchain it was minted on.
Three of the skins are now being auctioned on TofuNFT: Polygon, Avalanche and Moon River. Bidding ends on January 31. The other three skins will go up for auction at a later date.
Note the the image seen below is the rendered skin; the actual skin can be downloaded from the url found in the description of the NFT.
