Trezor Bridge is an essential communication layer that allows your Trezor hardware wallet to interact securely with your desktop browser and supported web applications. Designed by SatoshiLabs, the creators of the world’s first hardware wallet, Trezor Bridge ensures that your private keys never leave your device while still providing a smooth and reliable connection to the Trezor ecosystem.
Trezor Bridge is a lightweight service installed on your computer that acts as a secure bridge between your web browser and your Trezor hardware wallet. Modern browsers limit direct USB access for security reasons, and this is where Trezor Bridge plays a critical role. It translates browser requests into secure commands that your Trezor device can understand.
Unlike browser extensions that can introduce additional risk, Trezor Bridge is a standalone application maintained and signed by the official Trezor team. This approach reduces attack surfaces and improves reliability across different operating systems.
The new generation of Trezor Bridge has been redesigned to offer better performance, improved compatibility, and enhanced security. As web standards evolve and operating systems receive updates, Trezor Bridge ensures your hardware wallet remains functional without compromise.
Trezor Bridge ensures encrypted and authenticated communication between your computer and your Trezor device. Sensitive operations such as transaction signing are always confirmed on the device screen, not on your computer.
Once installed, Trezor Bridge automatically detects compatible applications. Whether you are accessing Trezor Suite or other supported services, the bridge works silently in the background.
Trezor Bridge supports Windows, macOS, and Linux, ensuring a consistent experience regardless of your operating system. Installation packages are optimized for each platform.
Security is never static. Trezor Bridge includes an update mechanism that keeps the service up to date with the latest security improvements and compatibility fixes.
When you connect your Trezor hardware wallet to your computer via USB, Trezor Bridge detects the device and waits for authorized requests from supported applications. Your browser sends a request, Trezor Bridge validates it, and then forwards it to the device.
At no point are your private keys exposed to your computer or the internet. All cryptographic operations occur inside the secure environment of the Trezor device.
Installing Trezor Bridge is straightforward and takes only a few minutes. After downloading the official installer, follow the on-screen instructions specific to your operating system.
In the past, some hardware wallets relied on browser extensions to communicate with devices. Trezor Bridge replaces this approach with a more secure and future-proof solution.
Browser extensions can be affected by browser updates, permission changes, or conflicts with other extensions. Trezor Bridge runs independently, offering greater stability and a reduced risk profile.
To get the most out of Trezor Bridge, follow these security recommendations:
Trezor Bridge is a foundational component of the broader Trezor ecosystem. It works seamlessly with Trezor Suite, firmware updates, and supported third-party services. This integration ensures a consistent user experience across all platforms.
