Your key was never
whole to begin with.
Vultisig splits your vault across multiple devices using MPC threshold signatures. No single device holds the full key. There's nothing to steal, lose, or leak.
Vault creation
Your devices run a distributed key generation ceremony. Each device produces its own cryptographic share - no full key is ever assembled anywhere.
Shares distributed
Each device gets its own Vault Share - a backup of its fragment only. Store it in iCloud, on a USB, anywhere.
Threshold signing
Signing happens in fragments across your threshold - the setup depends on which vault type you chose.
Bring your
own devices.
Phone, desktop, tablet — any device you already own becomes part of your vault. No hardware wallet required. No extra purchases. Just the devices in your pocket and on your desk.
Together, your devices form a vault that no single one of them can access alone. If one is lost or stolen, your funds are safe.
Backups that
can't betray you.
Each device produces a Vault Share — a secure backup of only its own fragment. A single Vault Share contains no funds and reveals nothing on its own.
Store each share anywhere: cloud, USB, email. It doesn't matter where — it takes two to sign and zero single shares hold value.
Lose device
Don't panic. Your vault remains safe even if a device is lost, stolen, or broken.
Get new device
Set up a new phone, desktop, or tablet just like you would normally.
Import backup
Use the backup Vault Share you stored securely to re-import your lost device.
Respawned
Your vault is fully restored and ready to use. No keys exposed, no funds at risk.
The Only Wallet You'll Ever Need.
