What is Trezor Bridge?
Trezor Bridge is a small software utility developed by SatoshiLabs that facilitates secure communication between your Trezor hardware wallet and your web browser. Without it, your computer would not be able to detect or interact with the Trezor device via the web.
When you use a Trezor wallet through Trezor Suite or other supported third-party services, Trezor Bridge acts as the secure translator between your browser and the USB-connected hardware wallet.
Why Trezor Bridge is Needed
By default, browsers like Chrome, Firefox, and Safari have limited access to USB-connected devices due to security restrictions. Trezor Bridge resolves this by running as a local background service that listens for device events and browser requests.
It ensures compatibility across various operating systems and offers a more reliable and secure communication method compared to legacy Chrome extensions.

- Secure connection between your browser and Trezor hardware wallet
- Eliminates the need for browser extensions
- Supports Windows, macOS, and Linux
- Auto-launches at system startup for convenience

Security and Privacy
Trezor Bridge is built with privacy and security in mind. It runs only on your local machine and does not transmit sensitive information over the internet. It acts only as a communication channel between your hardware wallet and browser, meaning:
- No data is stored or logged
- It does not access your private keys or wallet information
- All sensitive actions still require physical confirmation on your Trezor device
SatoshiLabs regularly audits and updates the software to ensure vulnerabilities are patched promptly.

- Better performance and reliability
- Reduced dependency on browser extensions
- Fewer connection errors during transactions
- Increased privacy, since Bridge runs locally
- Support for all Trezor models: Trezor One and Trezor Model T
If you value seamless operation and high-grade security for your crypto assets, using Trezor Bridge is essential.
