Trézor® Bridge®®| Introducing the New Trezor®
Security in cryptocurrency isn’t just about storing private keys offline—it’s also about how devices communicate with online systems. Trezor Bridge provides that secure communication channel, acting as a trusted link between your web browser and Trezor hardware wallet.
Created by SatoshiLabs, Trezor Bridge enhances compatibility and reliability for devices such as the Trezor Model One and Trezor Model T.
A Simple but Essential Function
When you plug your Trezor into your computer and open a supported web wallet, your browser needs a way to communicate with the device. Trezor Bridge acts as that communication layer.
Here’s how it works:
- The browser sends a request to access the device.
- Trezor Bridge processes the request locally.
- The hardware wallet verifies and signs the transaction.
- The signed data is returned securely to the browser.
Throughout this process, your private keys remain safely stored inside the hardware wallet.
Why It Improves Security
Unlike browser extensions, Trezor Bridge operates independently of browser marketplaces. This reduces potential exposure to malicious extension updates or compatibility conflicts.
Because it runs locally on your computer:
- It avoids browser-based vulnerabilities
- It ensures consistent device detection
- It minimizes connection interruptions
Most importantly, it never handles sensitive recovery information.
When Is Trezor Bridge Needed?
If you are using web-based wallet interfaces rather than strictly the desktop version of Trezor Suite, Trezor Bridge may be required for your device to connect properly.
Many users won’t even notice it running, but its presence ensures that communication remains smooth and secure.
Long-Term Reliability
As browsers evolve and security standards change, Trezor Bridge helps maintain consistent compatibility. Updates are released periodically to improve performance and strengthen protection.
In cryptocurrency security, every connection point matters. Trezor Bridge may not be visible on your dashboard, but it plays a vital role in preserving the secure architecture that Trezor devices are known for.
