Secure Vault

Create a Secure Vault with multiple devices for cold storage security. Flexible threshold signing (2-of-2 up to m-of-n). Ideal for holdings and DAOs.

Overview

Secure Vault offers the highest level of security—the "cold wallet" equivalent in Vultisig. These vaults consist solely of user-controlled devices with no third-party involvement.

A minimum of two devices is required; three or more is recommended for redundancy. Additional devices increase the signing threshold and enhance security.

Secure Vaults are ideal for shared wallets among multiple users and DAOs.

Threshold Configurations

Secure Vaults use an m-of-n threshold where m is at least 67% of n. Common configurations:

Setup	Devices	Signing	Redundancy	Recommendation
2-of-3	3	2	Yes (1 device)	Recommended
3-of-4	4	3	Yes (1 device)	Maximum security
2-of-2	2	2	No	Not recommended

Best practice for maximum redundancy:

1. Use 3 different platforms (Mac, iOS, Android)

2. Encrypt vault shares with 3 different passwords

3. Store shares in 3 different cloud providers (Google, iCloud, Dropbox)

4. Use unique email addresses with 2FA for each cloud account

This setup allows recovery from anywhere in the world with just email access and passwords—no hardware wallets or seed phrases required.

After Creation

Immediately backup every device after vault creation. Without backups, device loss can mean permanent fund loss.
