Trezor Bridge® | Connect Your Trezor to Web Browsers
Trezor Bridge® is an essential communication tool that allows your Trezor hardware wallet to connect smoothly with web browsers and desktop applications. Whether you're accessing Trezor Suite Web, managing coins, or approving transactions, Trezor Bridge ensures that your device and browser communicate securely without interruptions. If you own a Trezor Model One, Model T, or Safe 3, the Bridge acts as a trusted layer between your hardware wallet and your computer.
In this guide, we will explain what Trezor Bridge is, why it’s important, how to install it, supported systems, security features, troubleshooting tips, and best practices for safe crypto management.
What Is Trezor Bridge®?
Trezor Bridge is a lightweight software that lets your browser detect and communicate with your Trezor device. It replaces outdated browser plugins and offers better performance, stability, and security.
When you connect your Trezor to your PC through USB, the Bridge transmits encrypted messages between your browser and hardware wallet, allowing you to:
Access Trezor Suite Web
Approve or reject crypto transactions
Manage coins and tokens
Check balances
Sign messages
Update firmware
Without Trezor Bridge, many browsers cannot directly recognize your hardware wallet.
Why Is Trezor Bridge Important?
Trezor Bridge plays a critical role in ensuring secure communication between your device and computer. Here’s why it is essential:
1. Browser Compatibility
Most browsers block direct USB communication for security reasons. Bridge solves this by acting as a secure middle layer.
2. Secure Communication
All communication is encrypted, preventing unauthorized apps from interacting with your hardware wallet.
3. Plug-and-Play Performance
Once installed, your browser instantly recognizes the Trezor device—meaning no complex setups.
4. Multi-Platform Support
Available for Windows, macOS, and Linux.
5. Required for Trezor Suite Web
If you prefer using the browser version instead of the desktop app, Bridge is mandatory.
Supported Operating Systems
Trezor Bridge is available for:
Windows (10/11)
macOS
Linux (Ubuntu, Fedora, Debian, etc.)
It works with all major browsers like Chrome, Brave, Firefox, and Edge.
