At Frostsnap β we're making
bitcoin self-custody easy.
With Frostsnap, you can begin your journey into self-soverignty by
creating a key that is stored on a single frostsnap device, plugged
directly into your phone.
In our app you can create a new key and wallet. Any sensitive action
you make via the Frostsnap app must be physically confirmed on your
frostnap device.
With Frostsnap devices connecting in a daisy-chain, you can easily

Multisignatures are one of the most powerful ideas in bitcoin. Truly
distributed security for private property, for the first time in
human history.
For example, with three frostsnap devices you can create a 2-of-3 where you need to sign on any two of the devices in order to spend funds.
You could hide these three keys in separate geographical locations, or share them with people you trust.
With frostsnap, we've devised a way to create additional access
policies to the same wallet, such as a "spending key" where a
single device can spend up to some user defined limit per day.
Or a user could create an additional set of multisig keys for
inheritance. Suppose you create an additional 3-of-3 and share those
keys amongst trusted parties.
Advancements of cryptography have formed Frostsnap's vision for an
upgradable, personalized, and intuitive self-custody experience.

With blind signatures you can have a server sign something, without
them learning what they have signed. This is powerful for building
coordinators or authorities that respect user privacy.
