Am I able to edit or burn an nft after it's been purchased/traded by others?

For example: I would like to edit the metadata on an NFT. I ask the current holder if they’re willing to transfer it to me temporarily to make the changes.

On Opensea it’s not possible to make changes to the NFT after it’s been held by others. Is it possible on Manifold? If not, would I be able to tweak my contract to make it so? I’m prone to mistakes and the nature of NFTs is very… permanent.

Because you own the contract - Your NFTs can change at any point whether you own them or not.

The tokens must be burned by the owner!

awesome! much thanks
