If you sign a message with intent to list an NFT/token for sale - how does that work if you transfer the item later?
For example on an NFT marketplace - you list your NFT for sale by signing a message. I'm assuming that signed message is a signed transaction to transfer the NFT to a contract that acts as a medium of exchange between buyer and seller.
But what if I sign that message - then transfer my NFT?
- List NFT for sale
- Site asks for Approval of NFT to be confirmed - tx sent
- Site asks for signature with listing details (price, etc)
I now exit site and send the NFT to my friend.
4. Someone fills that listing for the NFT - but my NFT is gone - how is the order filled?
Specifically I'm looking at a site like rarible - where that is the flow - they only get approval and thats it.
But I don't get how it works if you transfer that NFT?
