Introduction to Trezor Bridge
Trezor Bridge is an essential software tool that allows your Trezor hardware wallet to communicate with web applications, including Trezor Suite Web. Acting as a secure communication layer, it ensures your browser can detect and interact with your Trezor device while maintaining security and privacy.
If you use Trezor via a browser instead of the standalone desktop application, installing Trezor Bridge is required. This lightweight background service bridges the gap between your physical Trezor device and the browser interface.
What Does Trezor Bridge Do?
Trezor Bridge enables seamless interaction between your hardware wallet and the web environment. Without it, browsers lack native support to detect and connect to USB hardware wallets like Trezor.
- Facilitates secure communication between your browser and device
- Runs in the background, only activating during wallet use
- Ensures all interactions are protected via end-to-end encryption
- Does not store any data or credentials
Trezor Bridge is required for browser-based wallet access, signing transactions, and using decentralized applications (dApps) that rely on Trezor authentication.
Why You Need Trezor Bridge
While the Trezor Suite Desktop App can directly communicate with your hardware wallet, the web version needs help to communicate over USB. This is where Trezor Bridge comes in. It eliminates the need for browser extensions, minimizes connection errors, and ensures compatibility across multiple platforms.
