What is Trezor Bridge?
The backbone of your hardware wallet's browser connectivity.
Trezor Bridge is a lightweight, background application designed specifically to facilitate communication between your Trezor hardware wallet and your web browser. Before the advent of Trezor Bridge, users relied on browser plugins, which often faced compatibility issues and security limitations.
Acting as a local server (running at 127.0.0.1), Trezor Bridge creates a secure tunnel. When you visit Trezor Suite for Web or other compatible third-party wallets like MyEtherWallet or MetaMask, the website sends requests to the Bridge, which then securely forwards them to your device via USB.
This architecture ensures that your private keys never leave the device. The Bridge only transports public data (like account balances) and transaction requests that you must physically confirm on your Trezor device. It is the industry standard for hardware wallet connectivity, ensuring that your crypto assets remain safe while providing a smooth user experience.
Why You Need It
- Universal Compatibility: Works with Chrome, Firefox, and other major browsers.
- Enhanced Security: Eliminates the need for vulnerable browser extensions.
- Background Operation: Runs silently without interrupting your workflow.
- Direct Communication: Reduces latency between device and interface.

Cross-Platform
Whether you are on Windows, macOS, or Linux, Trezor Bridge provides a consistent experience. It standardizes how your device talks to the web, regardless of your OS.
How to Install Trezor Bridge
Get started in minutes with this simple guide.
Visit the Official Source
Navigate to the official Trezor website (trezor.io/trezor-bridge). Never download the bridge from third-party file hosting sites to avoid malware.
Select Your Operating System
The site usually auto-detects your OS. If not, select Windows, macOS, or Linux from the dropdown menu and click "Download".
Run the Installer
Locate the downloaded file (e.g., trezor-bridge-2.0.27.exe) and double-click to run it. Follow the on-screen prompts to complete the installation.
Clear Cache & Connect
Once installed, it's good practice to clear your browser cache or restart the browser. Connect your Trezor device, and the Bridge will automatically facilitate the connection.
