Official Trézor® Bridge®®| Introducing the New Trezor®
Trezor Bridge is an essential background service developed by SatoshiLabs that enables smooth communication between Trezor hardware wallets and web-based applications such as Trezor Suite. It acts as a secure connection layer that allows your browser to recognize and interact with your Trezor device safely.
Unlike browser extensions, Trezor Bridge runs silently in the background, ensuring a stable and secure connection without exposing private keys or sensitive wallet data. It is a critical component for users who manage cryptocurrencies using a desktop browser.
What Is Trezor Bridge and Why It Is Needed
Trezor Bridge replaces older browser plugins and extensions that were previously required to connect hardware wallets. Modern browsers have discontinued support for those plugins, making Trezor Bridge the most reliable solution.
Primary purpose of Trezor Bridge:
- Enables communication between Trezor devices and supported websites
- Ensures secure transaction signing
- Provides seamless browser compatibility
- Works across Windows, macOS, and Linux
Once installed, it automatically runs in the background whenever a supported site needs to communicate with your Trezor wallet.
How Trezor Bridge Works
Trezor Bridge acts as a local service installed on your computer. When you connect your Trezor hardware wallet via USB:
- Your browser sends a request to Trezor Bridge
- Trezor Bridge securely communicates with the device
- Transactions are verified and signed on the hardware wallet
- No private keys ever leave the device
This architecture ensures that your funds remain protected even if your computer is compromised.
Key Benefits of Trezor Bridge
1. Enhanced Security
Trezor Bridge ensures that private keys remain isolated within the hardware wallet. All sensitive operations occur on the device itself, not on your computer or browser.
2. Seamless Browser Compatibility
It works smoothly with major browsers such as:
- Google Chrome
- Mozilla Firefox
- Microsoft Edge
- Brave
No additional extensions are required.
3. Automatic Updates
Trezor Bridge updates itself in the background, ensuring compatibility with the latest firmware and security standards.
4. Cross-Platform Support
Supported operating systems include:
- Windows
- macOS
- Linux
This makes it suitable for both beginners and advanced crypto users.
5. Improved Stability
Compared to legacy plugins, Trezor Bridge offers faster, more reliable connections with fewer errors and disconnections.
Trezor Bridge vs Browser Extensions
| Feature | Trezor Bridge | Browser Extensions |
|---|---|---|
| Security | High (local service) | Medium |
| Stability | Very stable | Browser-dependent |
| Updates | Automatic | Manual |
| Compatibility | Wide OS support | Limited |
Trezor Bridge is now the recommended and officially supported method for device communication.
