Quick explanation, how it works, install tips and basic troubleshooting.
Trezor Bridge is a small companion application that lets your web browser communicate with a Trezor hardware wallet. It acts as a bridge between the USB-connected device and browser-based wallet interfaces, enabling secure signing of transactions and safe management of private keys.
When you connect a Trezor device to your computer, the browser cannot directly access the hardware because of security restrictions. Trezor Bridge runs on your computer and exposes a local endpoint that authorized web pages can use to reach the device. The Bridge forwards messages between the web app and the Trezor device so actions like viewing addresses or signing transactions are possible.
Installing Trezor Bridge is simple: download the installer from the official Trezor website and run it for your operating system (Windows, macOS, or Linux). After installation, connect your Trezor and open your chosen wallet interface (for example, the official web wallet). The site should detect the Bridge and prompt you to connect the device.
Example: install → connect device → open wallet → allow access
Trezor Bridge only provides a local connection between your browser and device. It does not store your private keys or send them anywhere. Always download Bridge from official sources, verify links, and keep your device firmware up to date to maintain security.
If your browser won't detect the Trezor: check that Bridge is running, try reconnecting the USB cable, use a different USB port, or restart your browser. On macOS, you may need to allow the Bridge in system security settings after the first installation. Reinstalling Bridge or updating firmware often resolves persistent problems.
Keep your recovery seed secure, never share it online, and only confirm transactions you understand. Trezor Bridge is a convenient tool that enables secure interactions between hardware and web wallets — treat the device and the software as parts of a single security workflow.
Without Trezor Bridge, most browsers would not be able to communicate directly with hardware wallets due to strict security restrictions. The Bridge ensures smooth communication while keeping your sensitive data secure. It acts as a safe, local connection that protects you from online threats and unauthorized access.
Many wallet platforms rely on this software to function correctly with Trezor devices. This is why keeping Trezor Bridge updated is essential for smooth performance and maximum compatibility.
Trezor Bridge automatically checks for updates, but you can also manually download the latest version from the official website. Updates often include bug fixes, improved compatibility, and security enhancements. Make it a habit to periodically verify you are running the latest version.
If your Trezor still isn’t detected after installation, try the following:
Trezor Bridge makes the entire hardware wallet experience smoother and more reliable. Without it, many websites would struggle to detect the device, creating unnecessary confusion for new users. The Bridge handles the complex background communication so you can focus on managing your crypto safely.
It also reduces connection failures by providing a stable channel between your Trezor and the browser. This means fewer pop-ups, fewer reconnection prompts, and a much more predictable workflow.
Trezor Bridge works with all major operating systems:
Because it is widely supported, users can rely on a consistent experience across different devices and setups.
Trezor Bridge is compatible with most popular browsers, including:
Even if your browser receives major updates, the Bridge is regularly maintained so connectivity stays reliable.
Security is the top priority when dealing with hardware wallets. This is why you must download Trezor Bridge only from official links provided by the Trezor team. Fake or modified installers could contain malware meant to steal your crypto.
Always double-check:
To maintain a secure and smooth connection, follow these tips:
1. Does Trezor Bridge store my private keys?
No, it never stores or transmits your private keys. These remain inside the Trezor device at all times.
2. Can I use Trezor without Bridge?
Some platforms like Trezor Suite Desktop work without it, but browser-based tools usually require Trezor Bridge.
3. Is Trezor Bridge free?
Yes, it is completely free for all users.
4. Does it run in the background?
Yes, it silently runs as a background service after installation.
