I could mint a new set of tokens like on Opensea and transfer the ownership to the token holders?
A bit of manual work, but it would be solid and fair. Then we could carry on.
You gave NXTDrop holders Ethereum NFTs without collecting the NXT assets from them, so its arguable there is no real link between them and the original project, at least not from a historical perspective. Now you have peeps trying to sell their ETH NFTs
and NXTDrop assets.
The only
real NXTDrop tokens are the original assets on the NXT blockchain, as far as I'm concerned.
