calle 👁️⚡👁️ (npub12rv…85vg) you can attest to having ecash to the mint without revealing your identity right? Seems like this would be an ideal way to authenticate to a paid relay (using ecash) because it enables changing npubs but still proving you paid for write access or priveleged web of trust status, etc.
