nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg have there been proposals to address Cashu mints by nostr pubkey instead of DNS based address?

API commands would be sent over Nostr. I'm even thinking double ratchet could be suitable for this, providing forward secrecy for past API calls 🤔

I'd also like to have that on npub.cash so incoming lightning txs would show up instantly from the nostr subscription.
