A paper wallet is considered the most secure form of cryptocurrency storage. It is offline and is regarded as a cold storage wallet. It is printed on paper, and as long as you keep it in a safe and secure location, you can be assured of your crypto fund’s security.

So how do you spot & identify one?

All paper wallets have the same identifiers.

  • The public wallet address (aka public key) is printed on one side, and the private wallet address (aka private key) is printed on the other side.
  • Both sides have QR codes for easier scanning to avoid mistakes in keying the addresses as they are too long.
