Fast Vault

Create a Fast Vault in seconds—single-device hot wallet powered by Vultisigner. Perfect for daily transactions with seedless MPC security.

Overview

Fast Vault is the "hot wallet" equivalent in Vultisig. It allows vault creation with a single device, without requiring multiple devices from the user.

Fast Vaults are configured as two-factor vaults: one factor is the user's device, the other is the Vultiserver, which automatically co-signs user requests. This creates a single-signature experience while maintaining threshold security.

Learn more about Vultiserver in the Infrastructure documentation.

Fast Vaults are recommended for daily transactions and smaller amounts. For larger holdings, use a Secure Vault.

Creation Steps

1. Download Vultisig and open the app

2. Select Fast Vault option

1. Choose a vault name

2. Enter your email to receive the server vault share

3. Set a password for the server share

Remember this password. It encrypts your backup and is the only way to access it. Vultisig cannot help with password recovery.

1. Set an optional hint for the password

2. Start keygen and wait for completion

3. Enter the 4-digit verification code received via email

4. Backup your device share

Do not store the device backup on the device itself. Use separate cloud storage or offline media.

1. Start using your Fast Vault

Backups

Fast Vaults have two backup shares despite using one user device for signing:

• Device share: Your device's vault share

• Server share: Sent to your email during creation

Both shares must be backed up in separate locations. See Backup & Recovery for storage recommendations.
