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 longer have access to a Lattice1.
With the SafeCards and CLI app the only thing you can't change is the PIN - so choose wisely and be sure to remember it.
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.
Export Private Keys
This lets you export the private keys of your wallet directly. As you export the wallet's binary seed, deriving your private keys from the hash can get complicated, so we included this feature as well.
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.
All SafeCard CLI operations are protected by your SafeCard's PIN. You always have three attempts to get in before the SafeCard bricks - once it bricks, it's gone forever and can't be reinstated. Please read the SafeCard Management... Safely article carefully!
