What is Trezor Bridge?
Trezor Bridge is a small background application that enables secure communication between a Trezor hardware wallet and your browser. It replaces native browser USB access with a local HTTP interface so official wallets and web-based tools can talk to the device safely.
Why it's needed
Browsers vary in how they allow USB access and may break direct communication. Trezor Bridge standardizes the connection, improving compatibility and reducing prompts or permission issues.
- Compatibility with major browsers
- Reliable USB handling across OSes
- Minimal local footprint
Quick install
- Download the official Bridge from Trezor's website.
- Run the installer and allow the app to run in the background.
- Open your wallet web app; it should detect your device automatically.
Only install Bridge from the official source. Avoid third‑party downloads to reduce risk.
Security notes
- Bridge only runs locally and does not transmit your private keys.
- Verify downloads via Trezor.io and keep the app updated.
- Use official wallet software and check site certificates.
Troubleshooting
Common fixes: restart Bridge, replug the device, try a different USB port, or restart your browser. If problems persist, consult official support.
