Trezor Bridge: Secure Connection Between Your Hardware Wallet and Browser
Trezor Bridge is an essential background service that allows your Trezor hardware wallet to communicate securely with web browsers and supported applications. If you use a Trezor Model One or Trezor Model T, installing Trezor Bridge ensures seamless interaction between your device and platforms like Trezor Suite, third-party wallets, and blockchain services.
In this guide, we’ll explain what Trezor Bridge is, why it matters, how it works, and how it strengthens your crypto security—while also helping you understand how it fits into the broader Trezor ecosystem.
What Is Trezor Bridge?
Trezor Bridge is a lightweight software component that runs silently on your computer. Its main role is to create a secure communication channel between your Trezor hardware wallet and your web browser. Without Trezor Bridge, browsers cannot directly detect or interact with your Trezor device.
Unlike browser extensions, Trezor Bridge operates at the system level, making it more stable, more secure, and more compatible with modern browsers.

Why Trezor Bridge Is Important for Crypto Security
Security is the foundation of Trezor’s philosophy. Trezor Bridge plays a critical role in protecting your private keys by ensuring:
- End-to-end encrypted communication
- No exposure of private keys to the browser
- Protection against phishing and fake wallet interfaces
- Verified interaction only with trusted Trezor services
When combined with Trezor Suite, Trezor Bridge helps users safely send, receive, and manage cryptocurrencies without compromising control.

How Trezor Bridge Works
Once installed, Trezor Bridge runs in the background whenever your system is active. When you connect your Trezor device:
- Your browser sends a request
- Trezor Bridge verifies the request
- Secure data is exchanged with the hardware wallet
- Transactions are confirmed on the device screen
This architecture ensures that user approval always happens on the physical device, not on the computer or browser.
