nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg Is it technically possible to have a cashu mint that only whitelisted user can access? Maybe based on nostr keys?

What would happen when a whitelisted user creates a token that needs to be redeemed by an external user that doesn't have access to that mint?
