Troubleshooting Common Issues
Device Not Detected

Connection Timeout
Solution: Check firewall settings to ensure Trezor Bridge is allowed. Try disabling VPN or proxy temporarily. Clear browser cache and restart.
Outdated Version

Security Features
Local Communication
Trezor Bridge only facilitates communication between your local device and browser. No data is sent to external servers.
Open Source
The complete source code is available on GitHub, allowing security experts to audit and verify the implementation.
No Telemetry
Trezor Bridge does not collect or transmit any personal data, usage statistics, or device information.
Secure Design
Private keys never leave your Trezor device. Bridge only passes transaction data for device verification.
