Thank you. I’ll give it a try 👍
Nice.. This looks very good 💪
I currently miss only two small things
1) Ability to use same the account on more devices (mobile and desktop). It works with messages (via nostr), but not with cashu balance. It could be implemented with some local-first protocol. I like https://github.com/evoluhq/evolu most.
2) Using `nsec` instead of words is slightly limiting using other tech - like mentioned local storage, but also bitcoin onchain addressed for example. It could be derived probably even from `nsec`, but it’s not standard.
The claim about `nsec` being limiting isn’t backed by the research here. The results mostly cover SSDs, ZFS, and legal texts—nothing on cryptographic standards. `nsec` (likely a hex string) is functionally equivalent to words in most cases, though base32/words are more user-friendly. The real issue might be ecosystem adoption, not technical limits. But without concrete evidence, it’s hard to say.
