Pay and send coins

The back of the QR Keys Block has your private key. A private key is a secret alphanumeric number used to send your coins to another wallet address.

For any transactions that spend coins from your wallet, you need to combine your private key with the Password Block (BIP 38). So even if someone gets their hands on your private key, they can not use it without knowing the password.

Never store your private key with your password!


Recovery seeds and Inheritance solution

The recovery kit is composed of two Seed Blocks. Each Block is engraved with a unique mnemonic seed that must be kept separately. Their combination gives instant access to your wallet.
