We had a Cashu dev call yesterday and four (!!) new wallets based on NIP-60 were presented. NIP-60 is a standard for storing ecash on no:str relays, encrypted with your keys.

You open a wallet for the first time, login with your nsec, and boom, your balance appears.

Don't like this wallet? Switch to another one, enter your nsec, and your ecash appears there too.

This is pretty insane. If you're building a wallet, you're immediately plugged in into a social net. Now you can also carry your money around from app to app, or website to website.

If you're a Cashu dev, you should join our monthly open dev calls. Hit me up!
