SafeCard CLI

The SafeCard CLI is a free open-source application which ensures that you’ll always be able to recover critical backups stored on GridPlus SafeCards even if you no longer have access to a Lattice1.

What You Can Do With the SafeCard CLI

  1. Export Mnemonic (Seed Phrase) (only for cards with applet v2.4+, this means cards purchased in 2023 and on!) This allows you to export the 12/18/24-word mnemonic seed phrase for unlocking your wallet. Please note this is different from the option below - the seed hash itself. Most wallet providers only support importing the seed phrase, not the seed hash.

  2. Export Seed

    This function allows you to export your SafeCard wallet's binary seed (a hash of the more commonly used seed phrase). With the master seed, you have everything you need to derive any keys needed to gain access to your funds on another device.

  3. Export Private Keys

    This lets you export the individual private keys from your wallet directly. You will have to specify the starting export path.

  4. Delete Seed

    This completely erases your wallet seed from the SafeCard. Useful for both making sure no additional record of your wallet secrets exists and clearing the SafeCard before creating a new wallet. You can also delete the SafeCard seed directly on the Lattice1 by going to Manage Wallets and selecting Reset SafeCard Wallet when the SafeCard is inserted and unlocked.

  5. Change PIN You can also use the CLI to change your SafeCard's PIN if you don't have access to a Lattice device. If you do, it's way faster to do this via the Change SafeCard PIN option in the Manage Wallets menu on the Lattice.

What You Need to Manage Your SafeCards With the CLI

  1. One or more GridPlus SafeCards.

  2. A computer (MacOS or Windows, but you can also build from source on Linux).

  3. A generic card reader. We use and recommend this model.

  4. The SafeCard CLI binary. You can get it in the user guide!
