not following you sorry. It’s a lightning wallet, I can use it to pay for things with bitcoin, same as any other custodial wallet, like alby… 

But with nwc I could connect the wallet to the app instead of scanning a qr code every time to pay for things. 

I don’t need to be able to export my nostr account for this, it has nothing to do with that. And yes I can use any other lightning wallet i choose
