Trezor Bridge — Secure & Smooth Crypto Access™

1. What Is Trezor Bridge?

Trezor Bridge is the secure communication layer that links your computer’s browser to your Trezor Hardware Wallet. It ensures smooth, encrypted communication when using apps such as Trezor Suite or third-party crypto interfaces. Whether you’re storing Bitcoin, Ethereum, or other assets, Trezor Bridge provides the foundation for cold storage safety and a seamless user experience.

When installed, it runs quietly in the background, connecting your hardware wallet to supported browsers without exposing your sensitive data.

2. Why You Need Trezor Bridge

Without Trezor Bridge, your browser cannot communicate directly with your hardware wallet. This means you’d lose essential security layers when managing or signing transactions. Bridge ensures:

End-to-end encrypted connection between the wallet and web interface.
Protection against phishing or man-in-the-middle attacks.
Offline signing for Bitcoin, Ethereum, and other cryptocurrencies.
Automatic detection of your Trezor device by Trezor Suite.

These capabilities make Trezor Bridge an integral component of any cold storage setup for digital assets.

3. How to Download & Install Trezor Bridge

Installing Trezor Bridge takes only a few steps. Follow these instructions carefully to ensure your device works smoothly.

Visit the official page at trezor.io/bridge.
Select your operating system (Windows, macOS, or Linux).
Download the latest Trezor Bridge installer package.
Open the downloaded file and follow the on-screen instructions.
Restart your browser once installation completes.

Once installed, the Bridge starts automatically. You don’t need to open it manually — it runs silently in the background for stable connectivity.

4. Connecting Your Hardware Wallet

Now that the Bridge is installed, you can initialize and connect your hardware wallet model. Here’s how:

Open Trezor Suite.
Connect your Trezor device via USB.
Wait for Trezor Bridge to detect your device.
Follow on-screen prompts to initialize or unlock your wallet.
Verify your wallet’s public address on your device display before any transaction.

All sensitive operations, including transaction signing or recovery seed confirmation, occur within the secure element of your hardware device — never online.

5. Using Trezor Bridge with Trezor Suite

Once connected, the Trezor Suite app becomes your central crypto management hub. Through Trezor Bridge, you can:

Send and receive cryptocurrencies safely.
View real-time portfolio performance.
Access advanced coin settings, tokens, and account labeling.
Perform firmware updates securely.

Thanks to Trezor Bridge, all browser-to-device interactions stay local and encrypted, reducing the risk of unauthorized access.

Encrypted local communication: ensures only trusted software interacts with your hardware wallet.
