The First Hardware Wallet That Is Not A Trusted Third Party.

Frostsnap devices are not trusted to generate keys on their own.

Almost all other hardware wallets are trusted to generate your keys. The challenge of generating and verifying keys securely on your own is full of pitfalls.
Frostsnap involves your phone or laptop in sensitive operations to disrupts any possibility of device attacks; verifying key generation without giving it access to secret material.
Signing is also verified by the accompanying device, protecting against nonce-based exfil attacks.

Bitcoin's taproot upgrade has unlocked new possibilities with elegant and secure multisig:

Legacy Multisig
Frostsnap Multisig
❌ Costly transaction fees ✅ Same fees as single signature wallets
❌ Poor privacy, large onchain footprints ✅ Hidden multisig
❌ Generally a technical setup ✅ Simple and quick multisig
❌ Fixed signing devices ✅ Flexible signers with ability to add/remove (soon!)
❌ Descriptor backup gotchas ✅ Simple T-of-N recovery

A Vision For Self-Custody.

At Frostsnap we are building a sovereign journey for you to control your bitcoin with the ability to enact secure spending policies:

Spending from a multisig wallet is inconvenient by design — but for routine transactions, this can become annoying.
As bitcoin users we want convenient spends, facillitated through spending limited devices. The device and app ensure these limits can never be bypassed.
We want easy and well-defined inheritance for our loved ones — a straightforward and secure pathway for them to access your estate in your absence.

Self-sovereign policies on your bitcoin that make sense for you.
