We're going to ship the most robust personal Bitcoin multisig setup ever.
✅FROST key generation and signing
✅Bitcoin wallet + PSBT/Sparrow support
✅Simple seed words backup
and a lot more in the works.
Pre-ordering gets you this ASAP and helps support our efforts. Thanks!

Snap!
With limited spending capability with one device it looks like bespoke magic and not real multisig
Rings an alarm bell as it would require 3 devices from one manufacturer.
Convenient - maybe
Secure? Future proof?
we need a device to receive?
Yyyyyaaaaaaasssssssss. 👏👏👏
Password?
No device needed to receive, address verification on a device screen is optional.
Any spending limited device policies we build in the future will be enacted by the phone and the device. It sure is magic, and we know how to do it securely 🪄
How many wallets support that device?
how does it work?
does it allow decaying multisig or multiple recovery paths a bit like liana wallet?
Amazing to see the progress, well done!
Was about to ask the Same…
Looks very promising!
Not within our wallet yet, but it is (/soon will be) possible to use Frostsnap as a signer of PSBTs within more complex scripts built by other wallets.
We've been working towards this vision for self-custody for several years now, and this is where it starts.
We're thrilled for you to join and support us as we pioneer the Frontier of peer-to-peer cash security together.
See you on the Frontier 🫡

How does the "Simple T-of-N recovery" (descriptor) work? Not a lot of information on your webpage for now.
Careful...website does not mention the company, manufacturer, people behind this, not open source, multisig with devices only from this manufacturer? What about compatibility with ooen source well tested HD wallets? Careful everyone do not trust verify...
what if 2 out of the 3 modules have been lost or destroyed?
Set up your wallet 😆😁
it’s great to see how difficult features become easy to use
Thanks for coming to Nostr. Cool idea!
My question as well.
3 device 🧐
Each device has its own seedphrase backup, we'll be showing this soon!
You can load the backup into a new device, or in a disaster scenario, combine two backups to form an xpriv that can be loaded into sparrow/bitcoin core.
Thanks Max!
Just the Frostsnap app at the moment! We're pioneering the frontier of self-custody tech. Others will follow.

Free and open source software for Windows, Android, Linux, and MacOS (soon).
Good question (and yeah we need to put more out there), so the FROST multisig only has a single group public key (one xpub). And this single group public key can be reconstructed from secret shares or their images. That means that so long as you have two devices or their backups, you can find the xpub and simple derivation path -> descriptor.
Would geographically separated parties be able to pass signing information like in a PSBT? Could frost 'shards' be used to reconstitute 1 of the keys in a standard multisig? If yes to both this would have massive potential to replace Bitgo (which sucks) for companies.
Given the company’s name, can you change one signer without moving funds to a new address?
Lets goooo
The ux on this is pretty awesome!

Legends!!
Welcome. We've been waiting for you.
can I store my seeds on paper? Can AI recover them on a normal computer later?
🚨Multisig Leak from Fort Nakamoto HQ 🚨
After months of watching interns lose seed phrases to vending machines and aggressive pigeons…
We’ve officially begun field testing Frostsnap – the new self-custody protocol that doesn’t require a PhD in cryptography or a blood pact with your hardware wallet.
✅ No trusted setup
✅ No fingerprinting
✅ No ritual goat sacrifice
Just slick, secure, schnorr-stacked multisig that’s easier to use than a fiat wallet with 14 popups.
Our preliminary tests show a 97% reduction in freakouts during wallet recovery.
The remaining 3% was Greg, who panicked when he realized Frostsnap doesn’t use the Federal Reserve.
Result: Fort Approved™
Sovereign money now comes with sovereign key management.

No idea about the underlying tech it can be all gimmick as far as I know, but I really like the chaining of the devices... It looks neat and actually simple.
So fancy 🤩
The future of self custody is here!!
Whats your current form of self custody Jen?
Yes and yes! More on these soon
Yes! We haven't implemented it yet but the theory is there 🔥
Yes you will be able to do remote P2P signing in the future.
Yeah you can also have a FROST key inside a script multisig.
Absolutely agree that this is prime for institutional custody, but we're building for us hardcore bitcoiners first!
Best of luck guys. Would love to support you but price point is too high for a 2/3 set up even before I'm happy with any potential tradeoffs and move to a 3/5. UX looks dopeAF.
ok granted this was a stupid question
Ordered! Looking forward to learning more about how inheritance planning could work with FROST. Spending restrictions, delayed access, etc.
And excited to see development of remote signing (maybe through Nostr?) in the future.
Also, will get you added to

Cool multisig but airgapped still something to think about however this looks like a cool implementation.
Bruh. This looks excellent! Great work
This looks very slick.
Congrats!!! I would love to buy 3.
Do you offer a discount? I’m planning doing a YouTube review.
Esp32? DIY a possibility in the future?
Great idea
Would love to test and review for my podcast.
The Frostsnap team is crushing it!

Looking forward to learn more 🫡
Will you add / use blind schnoor signatures?
Are software and hardware open source?

This looks great 🎉
@nick thanks for your answer! Coming back here after your appearance at CD175. How can one device verify the receive address? I thought you need the threshold for that. Does this mean the xpub is stored on each device but encrypted through the app? Or can anyone finding one device see all transactions?
Frost Snap is taking pre-orders if anyone wants to get in on the first batch of "frontier" edition units!

Seen it in action. It's fucking awesome. DYOR though and check it out yourself!

Seen it in action... it's quite awesome and it works! DYOR though. One thing I'm a big fan of though is that your transactions on the mempool DO NOT show up as a multisig even though it actually took 3 signatures. Obfuscation ftw.
Amazing work. Congratulations
Wow
Welcome!
Looks great, good UX.
However for setup that require higher security, can we initiate with the devices once at the time to avoid bringing them all in one place? Ideally, I would guess, you should not do the setup all from the same smartphone/PC, in case it's affected, compromised, or is it bulletproof even on compromised devices?
Welcome
Looks dope
