What is Trezor Bridge?
Trezor Bridge is a small background service that enables communication between your Trezor hardware wallet and supported web applications or browser-based interfaces. It acts as a secure middle layer, allowing your browser to interact with your wallet without compromising private keys or requiring browser extensions.
The Bridge replaces older technologies like the Trezor Chrome Extension and ensures compatibility with platforms like Trezor Suite Web and other third-party wallets.
Why You Need Trezor Bridge
- 🔗 Enables connection between your browser and Trezor device.
- 🧱 Replaces outdated browser extensions (deprecated).
- 🔐 Keeps your private keys offline and protected on the device.
- 💻 Works with Chrome, Firefox, Brave, and more.
- ⚙️ Essential for using Trezor Web Suite and compatible dApps.
How Does Trezor Bridge Work?
Trezor Bridge runs as a background process on your computer. When a supported web app or browser tries to communicate with your hardware wallet, Bridge manages the request and routes it securely to your Trezor device via USB.
All operations—like signing a transaction or verifying addresses—must still be physically confirmed on your device. This ensures Bridge never compromises your private keys or exposes critical data.

Security & Privacy
Trezor Bridge is open-source and regularly audited. It does not store or transmit private keys. All transactions and sensitive operations must be confirmed directly on your hardware wallet, not in the browser or app interface.
