- The Air-Gapped Hardware Wallet That Puts You Back in Control The Problem with Most Hardware WalletsLedger, Trezor, and others rely on Bluetooth or USB connections to communicate with your computer or phone. These connections are attack surfaces. Researchers have demonstrated Bluetooth hijacking, USB keystroke injection, and supply chain attacks on closed-source firmware. Even worse, some brands introduced cloud recovery – your seed phrase leaves your device. The Digital Shield Solution – Air-Gapped by DesignDigital Shield eliminates all network interfaces. No Bluetooth. No Wi-Fi. No USB data connection (power only). Instead, all communication happens through encrypted QR codes. You scan a transaction QR from your phone, review it on the large 4.07" screen, sign it offline, and scan the signed QR back. Your private keys never touch the internet – ever. Why the CC EAL6+ Secure Chip MattersNot all secure elements are equal. EAL6+ is one of the highest certifications for tamper resistance, typically reserved for military cryptography and national ID systems. Digital Shield’s THD89 chip is independently certified to EAL6+, meaning it resists advanced physical probing, side-channel attacks, and voltage glitching. 100% Open Source – No More Black BoxClosed-source firmware means you have to trust the manufacturer blindly. Digital Shield publishes all source code for community review. Regular audits by CERTIK verify that no backdoors exist. You don’t trust us – you verify us.
