Welcome to the future of #bitcoin self-custody β
Frostsnap is a mobile-first hardware wallet π²
Begin your self-custody journey by plugging Frostsnap devices into your phone and naming them via the Frostsnap app.
Choose a security threshold and begin key generation to easily set up a multisig wallet in a matter of seconds.
In this demo we create a 2-of-3 multisig between the devices. A threshold of two means we need any two of the three devices to sign in order to spend funds from the wallet. βοΈπ
Daisy-chained Frostsnap devices participate in distributed key generation, each contributing entropy to a joint secret shared across multiple devices.
No single device knows the overall secret, only a fragment.
You, the user, can easily verify the key was created securely β
After creating a new key, you can hide your Frostsnap devices in different locations or share them among people you trust. ποΈποΈπ¨ββοΈ
When it comes time to make a bitcoin transaction or sign a Nostr post under your Frostsnap key, you must sign on multiple devices.
Frostsnap is crafting a whole new Bitcoin experience,
And we're fixing the problems of self-custody today:
security, accessibility, cost, and privacy.
Frostsnap is making #bitcoin ownership easy, personalized, and secure.
Stay Frosty βοΈ

During the message signing part, it looks like there is only a cancel button option on the screen. Will users be able to sign the PSBT with one device, save it, and close out the app while they travel to the location of the next signing device?
Whoa! That's awesome!
Very cool!!
Is it correct to say that you would have to plug these in (2 of 3) every time you want to post a note and or perform a zap?
Cool. Timelock transactions is another neglected part of the market.
There are other multisig wallets but this looks by far the easiest.
But many folks donβt care about multisig. Better security available with time locks and nobody is working on it. Low hanging fruit.
Combining multisig and time locks would be epic. Example: 3 of 3 for next 50,000 blocks, 2 of 3 after that for the next 50,000 blocks, 1 of 3 after that

This is very cool.
Too much dependency on one vendor, if you disappear, plebs are SOL π
If this becomes a standard where it can be used with hardware from different vendors or DIY stuff like #[4]β that would become a game changer. No more hussle with XPUBs etc.
these stackable prototypes are amazing
wen?
I can't wait for the next conference in Riga where you give me the ELI5 you promised me at the Nostr Party.
This is very very clever! π

This is some really cool tech. However, itβs not boomer approved. Process needs to be much more streamlined. If you want mass adoption to must cater to the lowest common denominator.
This is #cyberpunk

So want a signing key like this for transactions and Nostr.
Whaaaaat. Want one
That is really cool
This is very cool
That's pretty damn cool!
@Jakeβ‘οΈ det er lige noget for dig det her.
Very excited for this. Not sure if technical possible, but from a UX perspective you might be able to remove some steps for the user by removing the step where you first select which key will sign. Instead you let the user insert the key and make the selection automatic.
Seems very complicated for new Bitcoin users.

What do you mean?
View quoted note β New Nostr Signing Devices!! And Multisig out the yingyang π
Wow! Great work. It shows a completely different (and good) setup experience than normal multisig.
Of course many challenges remain, like preshared nonces.
I wonder if this setup could be done without a cellphone to keep everything airgapped?
So cold π₯Ά


OMG this looks amazing!
