Trezor Bridge — The Secure Gateway to Your Hardware Wallet®
Trezor Bridge (also shown as Trezor/Bridge and Trezor Bridge) is the small, secure bridge application that safely connects your hardware wallet to your browser and desktop apps. Read on to understand what it does, why it matters, and how to use it safely.
Trezor Bridge is an official helper application provided by the Trezor team to facilitate communication between your computer and a Trezor hardware wallet. When you plug your device into your computer, the trezor bridge (sometimes shown as Trezor/Bridge) acts as a secure gateway, ensuring that the browser or desktop wallet can talk to the device without exposing sensitive internals. Using the Trezor Bridge reduces the need for browser plugins, improves compatibility across operating systems, and centralizes the access point so updates and improvements can be distributed quickly.
Why Trezor Bridge matters for security
Hardware wallets are built so private keys never leave the device. The Trezor Bridge doesn't change that principle — it simply passes encrypted commands and responses between your browser and the Trezor device. Because the Trezor Bridge is designed with least-privilege access and limited attack surface, it's a substantially safer alternative to granting direct, low-level access to the browser or installing untrusted drivers.
Isolation: Trezor Bridge isolates USB communication to a narrow, controlled channel (trezor bridge).
Compatibility: Trezor/Bridge works across macOS, Windows, and Linux with modern browsers supporting WebUSB or native integration.
Updatability: When improvements or patches are needed, the Trezor Bridge application can be updated independently from the firmware or browser extensions.
Installing and using Trezor Bridge
Installing Trezor Bridge is straightforward. Download the official installer from the Trezor website, run the installer for your OS, and follow the on-screen prompts. After installation, plug in your Trezor device and open your preferred wallet interface — the site will detect Trezor Bridge (trezor bridge / Trezor/Bridge) and establish a secure connection.
Tips:
Always download the Trezor Bridge installer from the official source to avoid tampered installers.
Keep Trezor Bridge up to date — updates may include both feature enhancements and security fixes.
If a browser asks for permission to use the device, confirm the request and make sure the site domain is correct before allowing access.
Troubleshooting common issues
If your browser cannot detect the device, try these steps:
Confirm that Trezor Bridge (trezor bridge, Trezor/Bridge) is installed and running.
Reconnect the USB cable — sometimes a different USB port or cable resolves connection problems.
Restart your browser or computer if the device isn't detected after reconnecting.
Check for blocking software (antivirus/firewall) and temporarily allow Trezor Bridge through if needed.
Ensure your browser supports the API required by the wallet interface — modern browsers like Chrome and Firefox usually work smoothly.
If issues persist, consult official Trezor documentation or the support channels; never install third-party driver software from unknown sites — always rely on the official Trezor Bridge distribution.
Best practices and privacy
Using Trezor Bridge does not expose your seed phrase or private keys. Best practices:
Never enter your seed phrase into a computer or website — seeds belong only on the device and your written backup.
Verify addresses on the Trezor device screen before confirming transactions — the device is the only trusted display for sensitive confirmations when using trezor bridge / Trezor/Bridge.
Keep firmware and the Trezor Bridge application updated from official sources to maintain security hygiene.
