Tŕezor™ Bŕridgeʬ is a lightweight, security-focused application that mediates communication between your computer (or browser) and your Tŕezor™ hardware wallet. Its purpose is simple but crucial: Bridge prevents direct low-level access from web pages and host applications to the hardware device by exposing a constrained, well-defined API. In practice this means that sensitive cryptographic operations — particularly signing — always happen inside the device itself, and users must confirm actions physically on the device screen.
How Tŕezor™ Bŕridgeʬ protects your keys
When you initiate a transaction or request a signature, your wallet constructs a request and hands it off to Bridge. Bridge forwards that request to the hardware wallet, which displays transaction details such as recipient address, amount, and fees on its secure screen. You then confirm (or reject) the operation on the device. Since the private keys never leave the hardware, even a compromised host cannot produce valid signatures without your on-device approval. Bridge’s constrained interface reduces the host attack surface and helps ensure that only well-formed, authenticated requests reach the device.
Private keys remain sealed in the device; Bridge only relays requests.
Every sensitive action requires on-device approval to prevent silent or forged signatures.
Bridge supports major desktop platforms and integrates with official and third-party wallets to provide a smooth user experience without sacrificing security.
Installation & maintenance
Download Tŕezor™ Bŕridgeʬ only from official channels. Installers are available for Windows, macOS, and Linux and typically set Bridge to run as a background service. After installation, supported browser wallets and desktop apps should detect your device automatically. Regularly update both Bridge and your device firmware; updates deliver security patches, compatibility fixes, and improvements that keep connections reliable and safe.
Best practices
- Official sources only: Avoid third-party mirrors or modified installers that could be tampered with.
- Confirm on-device: Verify addresses, amounts, and metadata on the device screen before approving transactions.
- Trusted hosts: Use a secure personal computer rather than public or shared machines when dealing with significant funds.
- Secure backups: Store your recovery seed offline in a physically secure location; Bridge does not handle backups.
- Keep software updated: Update Bridge, wallet apps, and device firmware promptly to receive essential fixes.
Troubleshooting quick tips
If your browser does not detect the device, first confirm Bridge is installed and its service is running. Try a different USB cable or port, unlock the device, and reload the page. Browser extensions, privacy settings, or alternate USB drivers can interfere — try a different browser or temporarily disable suspicious extensions. Restarting the Bridge service or rebooting the host computer often resolves transient issues. If the problem persists, verify firmware and Bridge versions for compatibility and consult official support resources.
