Everything is backed up by your nostr NSEC key. If you want to access your chats and balance from another device, you just sign in into cypherflow with the same nostr nsec (or nostr browser extension).
  • If you created an account directly in https://cypherflow.ai , then a nostr key pair was created on your device and stored on the browser, to see it and back it up, go to: Open wallet -> Settings -> Nostr Keys -> nsec
  • If you signed in with a nostr Nip-07 browser extension, then everything should load automatically as soon as you log in (chats and ecash balance)

How does this work?

Cypherflows wallet follows an implementation of Nostr NIP-60: Cashu Wallet Basically, all of your ecash tokens in your wallet are encrypted with your nostr keys and published as a nostr event to nostr relays.
This way, you only need your nostr keys to access your ecash tokens.
This has some interesting consequences.
  1. Your ecash is backed up automatically. As long as you have access to your nsec you have access to your ecash.
  2. Your ecash balance is synced automarically across different devices where you are using cypherflow with the same nostr key.
  3. Once more nostr apps adopt Nostr NIP-60: Cashu Wallet, The same wallet balance should be available to any nostr app.
Exciting stuff, let me tell you

Let's not, that's a security risk AND a privacy risk
(or nostr browser extension).
Less of a security risk (although browser extensions are a risk themselves), but still a privacy risk

You are right about the security and privacy risk.
I do not recommend using an existing nsec key for this app, since it is never a good idea to be copying and pasting around a private key.
Also having the nsec stored in the browser is not particularly safe.
For now, I suggest creating a bran new key pair either directly in the app (worst security) or with a new nostr extension key pair (little less worse security) and not transfering your cold storage balance to it just yet.
This has been an interesting experience to balance the risk of a good nostr key management set up vs just having a new user up and running with the click of a single button.
Support for better Nostr signers coming soon ⚡

Amber / nsecbunker is relatively safe from what I've been able to test thus far (depending on user config)

It will be cool to have remote signing. I'll check them out.

Recommend to look into it after you figured out how to do error handling on remote mints - because issues will be similar.
