Connecting Trezor with Bridge and Web Apps

Using with Trezor Suite Web

Security Features of Trezor Bridge

  • 🔐 Does not store or transmit your private keys.
  • 📄 Verifies all transaction data on the device before confirmation.
  • 🛑 Bridge does not auto-execute any transactions — you must confirm them physically.
  • 🧠 Bridge operates silently in the background, reducing attack surface.

Common Issues and Fixes

“Device Not Recognized” Error

  • 🔄 Make sure Bridge is installed and running in the background.
  • 🔌 Try a different USB port or cable (some cables are charge-only).

Conflicts with Trezor Suite Desktop
