Trezor® Bridge: Secure Connection for Trezor® Wallet | Setup

Install, verify, and troubleshoot Trezor Bridge to maintain a secure, reliable connection between your Trezor® hardware wallet and desktop applications.

What is Trezor Bridge and why it matters

Trezor Bridge is the official connection middleware that enables secure communication between your physical Trezor® device and desktop browsers or apps. When initializing a device, managing accounts, or signing transactions, Bridge provides an encrypted layer to reduce the risk of tampering or man-in-the-middle attacks. Always download Bridge from the official Trezor sources to avoid counterfeit installers.

Quick setup steps

Download the latest Trezor Bridge installer for your operating system from the official Trezor site.
Run the installer and follow on-screen instructions; restart your browser after installation.
Connect and unlock your Trezor® device using your PIN, then open the Trezor web app to confirm it is detected.
If prompted, update device firmware via the official updater — firmware updates often include critical security fixes.

Best practices for secure use

Verify downloads: Use HTTPS, inspect the site certificate, and check checksums if provided.
Keep software current: Update OS, browser, and device firmware regularly.
Avoid public computers: Only connect hardware wallets to trusted machines.
Handle recovery seeds offline: Never type seeds into a computer or cloud document.

Troubleshooting connection issues

If the device isn’t recognized: ensure Bridge is running (check system tray/process list), try a different USB cable or port, reinstall Bridge and reboot, and verify browser permissions and extensions that may block USB access.

Important: You may encounter references to other setup pages such as ledger.com/start. That URL points to competitor setup instructions — use such links only for comparative research. Never use competitor downloads for a Trezor device or follow instructions intended for a different hardware wallet.

Compatibility & verification

Trezor Bridge supports Windows, macOS, and common Linux distributions and requires a modern browser (Chrome, Firefox, Edge). Verify installers over HTTPS and consult official support if you suspect tampering.
