What is Trezor Bridge?
Trezor Bridge is a lightweight communication software that allows your computer and browser to interact securely with your Trezor hardware wallet. Unlike browser extensions, Trezor Bridge operates in the background as a native app, enabling direct and private connections between your wallet and cryptocurrency applications like Trezor Suite, MetaMask (with configuration), or third-party services.
If you want a seamless, secure experience managing your crypto assets, Trezor Bridge is a critical component. It eliminates the need for browser-specific plugins, and instead facilitates a universal method for device communication — ideal for Linux, Windows, and macOS users.

How to Install Trezor Bridge
Installing Trezor Bridge is quick and straightforward. Simply follow the steps below based on your operating system:
- Visit the official Trezor Bridge download page.
- Download the version compatible with your OS (Windows, macOS, Linux).

That’s it — your Trezor device should now be automatically recognized and ready for secure use.
Understanding How Bridge Works
Unlike browser extensions, Trezor Bridge runs as a background service. It listens for messages from supported apps and creates a local channel to your hardware wallet. This means no browser sandboxing issues, no permissions prompts, and no dependency on third-party extension ecosystems.
When using Bridge, apps like Trezor Suite communicate via HTTP over `localhost`, allowing for low-latency communication that is still completely isolated from the internet.
Trezor Bridge vs WebUSB vs Extension
There are multiple ways to connect your Trezor to your device, but Bridge remains the most consistent:
- Trezor Bridge: Best for all users; stable, supports all browsers, cross-platform.
- WebUSB: Supported only in Chrome/Brave. May cause issues with ad blockers or browser security policies.
- Browser Extensions: No longer recommended by Trezor due to security and compatibility issues.
Common Use Cases
Trezor Bridge enables numerous crypto workflows, including:
- Using Trezor Suite for managing your portfolio, sending transactions, or updating firmware.
- Accessing DeFi dApps via MetaMask + Trezor.
