Part 3/9:
Security Shrouded Behind Air-Gapped Devices
A significant issue is that hardware wallets are designed to be air-gapped, meaning transaction data is supposed to be verified solely on the device itself. While this is beneficial for security, it creates a practical challenge: How does one verify transaction data outside the device?
A common workaround might include taking a photo of the screen and using AI-powered tools to extract call data or manually verifying every character—a near-impossible task at scale. Even connecting the hardware wallet to software like MetaMask reintroduces vulnerabilities, as it strips away the air-gapped security model for the convenience of easier transaction inspection.
