What is Trezor Bridge?
Trezor Bridge is a lightweight communication tool that allows your Trezor hardware wallet to connect securely with desktop applications and supported browsers. Without it, your computer and Trezor device wouldn’t be able to exchange information safely. This software runs quietly in the background and ensures that transactions, account data, and cryptographic approvals are transmitted only through a secure and authenticated channel.
By acting as a translator between your hardware wallet and software interface, Trezor Bridge guarantees that sensitive operations such as signing transactions never expose your private keys. Your keys remain locked inside the device, while the Bridge takes care of delivering instructions in a trustworthy way.
Why Trezor Bridge Matters
Seamless connectivity
Once installed, Bridge automatically detects your Trezor hardware wallet whenever it is connected. You don’t need to configure drivers or jump through technical hoops.
Cross-platform support
Trezor Bridge works on Windows, macOS, and Linux, making it easy to pair your device with most desktop systems. Browser extensions that rely on WebUSB also benefit from the Bridge for stability.
Security-first design
The Bridge does not store or expose private keys. Instead, it passes signed messages between the Trezor device and apps, keeping your sensitive information isolated.
Getting Started with Trezor Bridge
- Download from the official website: Always install Trezor Bridge from trezor.io. Avoid third-party sources to reduce risks.
- Install on your system: Follow the installer prompts for your operating system. The setup usually takes less than a minute.
- Connect your Trezor device: Plug in your Trezor hardware wallet via USB. The Bridge will recognize it instantly and enable secure communication.

Security Best Practices
Even though Trezor Bridge is designed to be safe, users should follow some best practices to keep their assets protected:
- Download and update the Bridge only from the official Trezor website.
- Regularly update Trezor Suite and your device firmware for the latest protections.
- Never share your recovery seed or passphrase. Bridge will never request them.
- Confirm all transaction details on your hardware device before approving.
- Be cautious of phishing websites or fake download links imitating Trezor.
