You missed the first part of my post, how do I send the signed message to another address? Where can I find a buyer? Is this just the concept or can we do it right now? What wallet should we use, where to announce our NFT etc.
Everything testing manually at the moment and it is working. There is no marketplace or explorer so this thread is the only place where one can inform about 'signature chains.' But user nutildah recommends to look at emblem-vault on OpenSea. I was already checking it because of ordinal 'NFTs' on the Bitcoin blockchain and it seems to be the perfect opportunity to exchange 'signature chains.'
I will test emlem-vault a bit and post the results here.
