Securing Your Private Key

Essential guide on how to safely store and manage your private key.

1

Understand Private Key Importance

Your private key is the only way to access your card details. If you lose it, you lose access permanently. We cannot recover it for you.

  • The private key is a 66-character hexadecimal string starting with "0x"
  • It's used to decrypt your card data
  • Only you have access to your private key - we don't store it
  • Losing your private key means permanent loss of access to card details
2

Choose Secure Storage

Select a secure method to store your private key. Options include password managers, hardware wallets, or physical storage.

  • Password Managers: Use reputable services like 1Password, LastPass, or Bitwarden
  • Hardware Wallets: Store on a hardware wallet for maximum security
  • Physical Storage: Write it down on paper and store in a safe or safety deposit box
  • Never store it in plain text files on your computer
3

Create Backups

Create multiple backups of your private key in different secure locations. This protects against loss due to fire, theft, or other disasters.

  • Create at least 2-3 backups in different locations
  • Use different storage methods (digital + physical)
  • Store backups in secure, fireproof locations
  • Never store all backups in the same place
4

Test Your Backup

Verify that you can access your card using your backup. This ensures your backup is correct and accessible.

  • Wait a few days after creating your backup
  • Try accessing your card using only the backup
  • If it works, your backup is correct
  • If it doesn't work, create a new backup immediately

  • Never share your private key with anyone, including support staff
  • Don't take screenshots of your private key
