I’ve done some more testing and I wasn’t able to find a solid solution for contact payments - ideally combined with messaging. Do I miss something?

what does "contact payment" mean in this context?
You have a contact list and you can send sats directly to them without other communication

Thx. I’ll have a look 👀
You can tap the + button in 0xchat’s chat, select Cashu Nuts, and send a Cashu token to the other person. Nuts sent in private chats are P2PK tokens. 
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.

Looks very good.. Thanks.
I’ve been testing it circa year ago, but I didn’t get it’s utility back then.
Try nostr:npub1cm3rpgj7457yjuqnvdalxaauakqu0ndkpkyp5cldkyutpz4xszpsmk96wt
I did. Thanks. nostr:npub1cm3rpgj7457yjuqnvdalxaauakqu0ndkpkyp5cldkyutpz4xszpsmk96wt is using Spark which is different concept. Interesting one, but currently cashu seems to have a better tradeoff for me.. but definitely checking spark progress 👀
