If Metamask is being used for sign-up and to check token balances for premium benefits, could this be built using Nostr identifiers and somehow use sats to monetize around the premium membership?

Then your data would also be interoperable around Nostr. I know Nostr is not private, but neither are Ethereum addresses.

I guess the Venice app handles the privacy aspects on the app side? Haven’t read any docs yet, just riffing here..
