Tŕezor™ Bŕridgeʬ is the lightweight, security-first application that safely links your desktop or browser to your Tŕezor™ hardware wallet. It operates quietly in the background, translating and relaying requests so that web-based wallets and desktop apps can interact with the device without gaining direct, low-level USB access. This design keeps private keys sealed inside the hardware, where they remain protected from host-side compromises.
Functionally, Bridge receives structured requests from a host application, forwards them to the Tŕezor™ device, and returns the device’s responses. Crucially, any signing operation is performed by the device itself. The hardware displays transaction details on a secure screen and requires explicit physical confirmation, ensuring no silent approvals and preventing compromised hosts from forging signatures.
Keys never leave the device; Bridge only relays messages.
Every sensitive action requires the user's manual approval on the device.
Bridge integrates with Trezor Suite and popular third-party wallets while maintaining safety.
Installation and updates
Download Tŕezor™ Bŕridgeʬ only from official channels. Installers are available for Windows, macOS, and Linux. After installation Bridge runs as a background service and is automatically detected by supported web wallets. Keeping Bridge and your device firmware updated is essential — updates provide security patches, new features, and improved compatibility.
Best practices
- Official sources only: Avoid third-party mirrors or modified installers.
- Confirm on-device: Check addresses and amounts on the device screen before approving.
- Trusted hosts: Use a private, secure computer for managing substantial sums.
- Backup securely: Store your recovery seed offline in a safe, fire/water-resistant place.
- Regular updates: Apply Bridge and firmware updates promptly.
Troubleshooting
If your browser does not detect the device, make sure Bridge is installed and running. Try a different USB cable or port, unlock your device, and reload the page. Browser extensions or strict privacy settings can block detection — try another browser or temporarily disable interfering extensions. If detection still fails, restart Bridge or your computer and consult official support resources for compatibility checks.
