🙏 Thank you 🙏
Amazing! My best wishes to the project.
Sounds great but don’t app need to have the ability to read from NFC?
The point of this is to keep your nostr key safe offline?
It does multisig, which is the point, IMHO. It's more secure that a hot wallet, and less secure than a Ledger etc ....
Hey guys! Hugo from nunchuk.io here. Congrats on this!
Do you support two-round signing / MuSig2 protocol?
We have added support for Schnorr + MuSig2 recently to Nunchuk (https://nunchuk.io/blog/taproot-multisig). Would be cool to have Satochip integrated in Nunchuk and get MuSig2 working with a hardware signing device.
If you're interested, shoot me an email hugo@nunchuk.io !
Sorry, missed your reply.
As said earlier today, yes, that something we will def have a look at 👀
Let's make it a reality!
The beauty of Nostr!
Anyone can host notes. With X, only musk can host notes.
Thank you for sharing
Explain me like I'm 10. From today I can use nostr without sroring private key inside explorer extension, innit?
Currently, all Nostr clients store private keys within their apps, whether as a web extension or mobile app.
With Satochip, we provide a secure element to store private keys externally, enhancing security.
This beta version is CLI-only for now, but with positive feedback, we may develop software integration.
For example, you could use Amethyst (or similar apps) with a Satochip NFC smartcard, keeping private keys outside the app—boosting security without sacrificing convenience.
On desktop, Satochip works with a conventional smartcard reader, and with proper integration, a single card could be used across multiple Nostr clients.
Wow, it's mind-blowing
For me this was odd why does nostr use not so secure model to store keys
Your invention should amend this issue, I believe
Looks like all you need is a reader.
