Trezor Bridge® is a lightweight, secure communication tool designed to connect your Trezor® hardware wallet with your desktop browser. Acting as a middleware, it facilitates interaction between your wallet and web-based cryptocurrency interfaces such as the Trezor Suite, ensuring your private keys remain offline while enabling real-time digital asset management.

Built and maintained by SatoshiLabs, Trezor Bridge® ensures top-tier security while providing a seamless experience across platforms. Unlike browser extensions that may pose security risks, Trezor Bridge® runs natively on your computer, offering enhanced protection against malware, phishing, or compromised environments.

Why Use Trezor Bridge®?

With the rise in cyber threats and phishing attacks, safeguarding your digital assets is more critical than ever. Trezor Bridge® offers multiple benefits:

• Secure Connectivity: Establishes a secure link between your Trezor device and your browser without exposing sensitive data.
• No Extensions Required: Unlike other crypto wallets that rely on browser extensions, Trezor Bridge® operates natively, eliminating browser-based vulnerabilities.
• Cross-Browser Compatibility: Works seamlessly across Chrome, Firefox, Brave, and Edge.
• Encrypted Communication: Data exchanged between your Trezor hardware and the interface is encrypted, adding a robust layer of protection.
• Real-Time Interaction: Execute transactions, manage assets, or sign messages in real-time using Trezor Suite or other supported DApps.

How Trezor Bridge® Works

At its core, Trezor Bridge® acts as a secure communication bridge. When you connect your Trezor device to your computer via USB, Bridge enables it to "talk" to the browser interface (like Trezor Suite) without jeopardizing security.

Here’s a simplified breakdown:

1. Install Trezor Bridge® on your computer.
2. Connect your Trezor Model One or Model T via USB.
3. Open Trezor Suite in your browser.
4. Trezor Bridge® acts as a background process that authorizes and facilitates data transfers between your device and the Suite without exposing private keys or seed phrases.

Your private key never leaves the device, ensuring maximum security.

How to Install Trezor Bridge®

✅ Step-by-Step Guide:

1. Visit the official Trezor website: Navigate to https://trezor.io/start
2. Download Trezor Bridge®: Based on your OS (Windows, macOS, or Linux), download the correct version of the Bridge software.
3. Install the Application: Follow the on-screen installation instructions for your operating system.
4. Restart Browser (if needed): After installation, close and reopen your browser to ensure the Bridge process is detected.
5. Connect Your Device: Plug in your Trezor device via USB and access it through Trezor Suite.

Trezor Bridge® will run silently in the background, enabling secure communication without user intervention.
