Why Use Trezõr® brïdge®

  • Browser security: Modern browsers restrict direct USB access; Bridge mediates safely.
  • Cross-platform: Works on Windows, macOS, and Linux seamlessly.
  • User-friendly: Avoids extensions and complex drivers.

Security Model

Bridge never accesses keys; signing always occurs on the Trezor device. Key security features:

  • Local-only communication (127.0.0.1)
  • Origin verification displayed on device
  • Minimal privileges — only USB/IPC handling

Installation & Setup

  1. Download from the official Trezor website; verify domain.
  2. Run installer; Bridge creates a local service for app connections.
  3. Open browser or Suite; approve device connection when prompted.

Linux users may need udev rules for USB access; follow installer guidance or documentation.

Developer Integration

Use Trezor Connect library or HTTP endpoints to interact with Bridge:

  • Include trezor-connect in your Web3 app.
  • Prompt user to connect device; confirm actions on Trezor screen.
  • Handle device responses and errors carefully.
// Example
TrezorConnect.getFeatures().then(features => console.log(features))
  .catch(err => console.error('Error', err));

Privacy & Best Practices

  • Do not enter recovery seeds; Bridge never needs them.
  • Prefer desktop Suite or air-gapped setups for privacy.
  • Confirm web app origin on device before signing.
  • Keep Bridge and firmware updated; delay non-critical updates for cold-storage devices.

Advanced Usage

Automation and headless usage (CI/CD) are possible but risky. Never store recovery seeds in scripts; limit signing to auditable, human-approved workflows.

Troubleshooting

  • Check Bridge service icon; start manually if not running.
  • Ensure USB cable supports data transfer.
  • Remove conflicting drivers (Windows) or set udev rules (Linux).
  • Verify browser permissions and device unlock.

FAQ

  • Q: Is Bridge mandatory? A: Yes for most browser-based Web3 apps.
  • Q: Can Bridge sign? A: No, signing is only on the device.
  • Q: Safe on shared computers? A: Prefer dedicated machines for high-value keys.
