Trezor Bridge – Secure Communication Between Your Wallet and Device
Trezor Bridge is a lightweight software component that enables seamless communication between a Trezor hardware wallet and supported web interfaces. It operates quietly in the background, ensuring that your browser can securely interact with your device without relying on potentially vulnerable plugins or extensions.
For users of Trezor hardware wallets, Trezor Bridge plays a critical role in maintaining both functionality and security.
What Is Trezor Bridge?
Trezor Bridge is an official connectivity tool developed by SatoshiLabs. It replaces older browser-based communication methods by providing a more stable and secure channel between your computer and Trezor device.
Instead of installing browser extensions, Bridge runs as a local background service.
Why Trezor Bridge Is Important
Without Trezor Bridge, web wallets may not detect or communicate properly with your hardware wallet. Bridge ensures:
- Reliable device recognition
- Secure data transmission
- Compatibility across modern browsers
- Protection against malicious browser interference
It acts as the secure translator between your wallet interface and hardware device.
How Trezor Bridge Works
Trezor Bridge establishes a local connection on your computer. When you open a supported wallet interface:
- The browser sends a request
- Bridge intercepts the request locally
- The Trezor device receives instructions
- Sensitive operations require physical confirmation
This design prevents private keys from being exposed to the internet or browser environment.
Key Features of Trezor Bridge
Plugin-Free Operation
Eliminates the need for browser extensions that may introduce vulnerabilities.
Cross-Browser Compatibility
Works with Chrome, Firefox, Edge, and other major browsers.
Background Service
Runs silently without interrupting workflow.
Secure Device Access
Only trusted applications can communicate with the device.
Security Advantages
Trezor Bridge enhances protection through:
- Local-only communication channels
- No cloud-based key handling
- Reduced phishing attack surface
- Controlled transaction approval
Because Bridge does not manage funds or keys, it minimizes security risks.
When Do You Need Trezor Bridge?
You typically need Bridge when:
- Using web-based wallet interfaces

Desktop applications like Trezor Suite often include built-in communication and may not require Bridge separately.
