At Frostsnap ❄ we're making peer-to-peer cash easy and secure.

We're building the most secure Bitcoin hardware wallet in existence, with the principle of distributed security at our core.

Our devices connect in a daisy-chain, allowing you to easily create a multisignature wallet protected behind multiple keys.

Multisignatures are one of the most powerful ideas in bitcoin,

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.

Truly distributed security for private property for the first time in human history.

With Frostsnap you will be able to enact sovereign access policies, such as daily spending limits or inheritance pathways. Similar to those you'd expect with a traditional financial institution, but you remain in control.

We're making peer-to-peer cash easy, and building the tools you need to secure your keys.

Frostsnap is dedicated to empowering human freedom with the latest advancements in cryptography. With Bitcoin, and beyond.

Stay Frosty.

Blind Schnorr Signatures

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.
