When you redeem the physical product associated with your Physical NFT, the NFT can either be retained, burned (destroyed), or modified depending on the platform or the specific terms of the NFT.
Some platforms may allow you to keep the NFT as a digital certificate of authenticity or ownership for the physical item. Others might mark the NFT in a way that indicates the physical item has been redeemed. It’s essential to understand the specific terms and conditions associated with the Physical NFT you’re purchasing to know what will happen upon redemption.
