D'CENT Card Wallet

It uses a physical card with a secure element chip to generate and store private keys without exposing them to an internet-connected device. This reduces risks from malware and phishing, although recovery words and card access still need careful protection.

The card-wallet concept is designed to be used with a companion mobile wallet for managing transactions while keeping the private key on the card. The exact phone operating systems and connection method depend on the D'CENT model and app version.

Self-custody removes the need to leave private keys with an exchange, so an exchange breach does not directly expose the wallet key. However, losing the recovery material or approving a phishing transaction can still result in permanent loss.

The outcome depends on whether the wallet's recovery method was backed up securely before the card was lost. A replacement device can restore access only when the correct recovery information is available.
