For funding a contract, we are rolling out a cool cryptography feature called disposable keys, which was developed with nostr in mind. It will let you generate a key locally on your machine for the deposit signing, then throw away the key. You can elect a key in cold storage to be a recovery key just in case, so you can use your npub to create disposable ephemeral signing keys that can be recovered by your nsec in a worst case scenario.

Also, the proof generation that is used for user authentication and interacting with the contract VM, is all secretly nostr notes underneath the hood :-) so nostr signing devices can interact with our API

Yes. Nostr was going to be the original plan for the in app chat, but we ripped it out so that you can communicate off platform if you so desire.

That said, we are thinking of putting it back in at some point.

@BlueSlime made a library for this to make it easy if you want to check it out:

there are also other nostr libraries you can check out that he made.
