I also watched the video and found the basic procedures demonstrated in the Frostsnap Frontier to be straightforward and easy to follow. However, one aspect that wasn’t covered by video was the app’s connectivity. Specifically, I'm curious about how the app connects to blockchain. Does it use public RPC/API endpoints or it rely on its servers run by your company? Particularly for users who want to buy Frostsnap signers it would be great if the app had the flexibility to connect to private node.

The app currently connects to electrum servers, you can specify your own. We're looking to implement bitcoind RPC support soon.

First of all, will Frostsnap Frontier be a mobile-only signing device or are you also planning to release an app for desktop that people could use on their PCs?

Back to the video.
After you create your 2/3 multisig wallet, the software doesn't display the seed or instruct users to back it up. I think that should be an optional if not even a mandatory step immediately after wallet creation and certainly before you fund any of your addresses.
The displayed BTC addresses are divided in shards. It makes sense because they are easier to check that way. I assume that if you copy them, the addresses will be pasted as a whole, right?

Yes our app builds for Linux, Windows, and soon MacOS!

Agree that the backup stage should immediately be shown after wallet creation! We actually hid the popup and warning banner for this demo. We'll show the backup process in a later video.

Yeah if you copy those chunked addresses or amounts it will not include the empty spaces.

BTW, are you an official representative of Frostsnap Frontier or are you just someone who likes their products?

I am a Co-Founder of Frostsnap! So feel free to ask any questions.
Thanks for the info, long time lurker first time poster on bitcointalk.



Overcharge price around $150 for a single hardware signer. Dropping it closer to $100 would make the whole set much more attractive.

Could we get the detailed overview of the key features planned for relevant mobile app?

Will the app allow to pair Frostsnap signers with other clients like Sparrow, Electrum, or similar?

The comfort of self-sovereign multisignature in a seamless UX with understandable recovery requirements is well worthwhile.
Costs of other products in a 2-of-3 or collaborative setups can quickly add up to a similar cost.

We've spent spent years engineering, designing and iterating these tools. Early adopters are strongly supporting our mission and we'll look after you well!

Here's a demo video of the app:
https://frostsnap.com/demo.mp4

The key features as of now are: distributed key generation, receive, send, verify addresses, PSBT signing, and recovery.
Many more to come including remote signing (shared multisig), inheritance access pathways, limited spending devices.

We'll have more to share on the recovery process soon.

Currently you can only sign with the devices through our app, since FROST is quite an evolution in the integration between signers and coordinators.
But you can export your descriptor to other wallets, craft custom PSBTs (i.e. coin selection) and sign them within our app.
Getting a coordinator into Sparrow or other wallets is certainly a longer-term goal, and crucially our core libraries (as well as other software) is all FOSS.

Frostsnap is bringing the next generation of self-custody technology to Bitcoin.
We've reimagined Bitcoin security from the ground up, designing and architecting the future of self-custody.



Distilled into a mobile-first hardware wallet, Frostsnap is pioneering radical improvements to the entire Bitcoin experience. For both the hodlers and the p2p cash enjoyers.

Multisignature is now a physical experience with daisy chained devices, accessible to all for the first time.
By making multisig easy, we're addressing the increasing physical attack risks faced by bitcoiners today.

Frostsnap is the first hardware device that is not a trusted third party. We achieve this by involving your phone in the security of your wallet.
Utilizing advancements in cryptography, your phone will verifiably participate in key generation and signing with your Bitcoin keys.

Next, we're expanding on our vision for self-custody:
  • Solving bitcoin inheritance: separate access pathways that allow your loved ones to access your wallet in your absence.
  • Convenient spending: spending your life savings should be inconvenient. But small spends should not be. We're working towards limited spending devices that can spend up to a certain amount per day in conjunction with your phone.
We'll be elaborating on our approach in the coming months.

The wait is over - we'd like to invite you as an early adopter to join us with next generation self-custody.
Be among the first in the world to experience ultimate bitcoin security, with the very first batch of the Frostsnap Frontier.
An invitation to take bitcoin saving seriously. See our website for more info, or happy to answer any questions here.

See you on the Frontier.
