Security Model
Low-cost NFC card-type cold wallet for Ethereum and EVM networks, using an EAL5+ secure chip, PIN protection, encrypted private-key storage, phone-tap signing, and a password-encrypted Backup Card workflow instead of mnemonic recovery words.
Trust Assumptions
- Users trust IoTrust card firmware and D'CENT app distribution
- The EAL5+ secure chip protects private keys and PIN retry counters as documented
- NFC communication and mobile-app signing flows remain correctly implemented
- Users verify transaction intent in the mobile app because the card has no independent display
- Users create and physically protect a Backup Card before relying on the wallet
- Users understand permanent card blocking after repeated wrong PIN entries can make funds inaccessible without a backup
Backup Methods
Backup card, Password Encrypted Backup Image, PIN, Original card to Backup card Transfer

Known Issues
2026: Seedless backup-card and no-display tradeoff
The All-In-One Card Wallet avoids mnemonic recovery words and keeps the card cheap, but users must trust D'CENT's backup-card model and verify transactions on the phone rather than on an independent hardware display.
2026: Permanent lock risk without Backup Card
D'CENT documentation states the secure chip blocks permanently after repeated wrong PIN attempts, so users who fail to create a backup card can lose access if the original card is locked, lost, or damaged.
