Frostsnap ❄ makes bitcoin
self-custody easy.
With Frostsnap, you can begin self-sovereignty by creating a key that
is stored on a single frostsnap device, plugged directly into your
phone.
You can create a secure key and wallet. Any sensitive action made via
the phone must be physically confirmed on your frostnap device.
With Frostsnap devices connecting in a daisy-chain, you can easily
upgrade to a
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 in cryptography laid the foundation for Frostsnap's
vision: an upgradable, personalized, and intuitive self-custody
experience.
