How Arculus Works

The Arculus Key Card uses a best-in-class CC EAL6+ Secure Element to encrypt and store your keys. It’s not connected to anything and if you lose it or it gets stolen, no one else can use it but you. When you choose to make a transaction in your Arculus Wallet App, you will tap your Arculus Key Card to your mobile device. This is an important security step in the three-factor authentication that Arculus uses to keep your crypto keys safe and secure. The card communicates with your wallet app via a tap-to-transact secure NFC connection. No Bluetooth. No Wi-Fi. No USB. No cords. Just security made simple.

Where Are My Keys?

Your private keys are encrypted and securely stored on your Arculus Key Card and are never stored online or saved on your phone. During initial wallet setup, you will be shown your recovery seed phrase in the app with instructions to write it down to store in a safe place. Your private keys are generated on the Arculus Key Card and never leave it. Your keys, your crypto.
