What is Trezor Bridge?
Trezor Bridge is a small, trusted helper application that runs on your computer. It creates a secure, encrypted channel between your web browser and your Trezor hardware wallet so you can use web-based tools and services without exposing your private keys. Bridge operates locally — it does not upload keys or sensitive data to the cloud.
Why Bridge matters
Web browsers restrict direct access to USB devices for good reason. Trezor Bridge safely mediates browser-to-device communication, enabling features like transaction signing and address requests while enforcing strict origin checks and requiring the user’s physical approval on the device. For more technical background and security considerations, consult the official documentation.
Key benefits
- Local-only communication: All bridging happens on your computer; nothing is stored externally.
- Secure device pairing: Only approved web origins may send commands to your Trezor.
- Cross-platform: Available for Windows, macOS, and Linux with verified installers.
- Easy updates: Bridge updates ensure compatibility and security improvements.
- Openness: The project maintains public resources for verification and auditing.
How to install & verify
- Download the official installer from the Trezor Bridge page. (Bridge download)
- Run the installer and follow on-screen prompts.
- Verify checksums or signatures to ensure the binary is authentic. Guidance is available in the support pages.
- Open a compatible web app (for example, Trezor Suite or other supported services) and allow the browser to use Bridge to detect your device.
Security best practices
To stay secure, always download Bridge from the official site, verify the installer, keep Bridge updated, and never use untrusted web apps with your device. When a website requests access, confirm the request details on your device’s screen before approving the action.
Official resources and guides are available to help with setup and troubleshooting.

Compatibility & integration
Developers building web-based wallet interfaces can rely on Trezor Bridge to provide a consistent, secure interface to Trezor devices. Bridge implements origin checks and expects the user to confirm each sensitive operation on the hardware device, keeping interactions auditable and safe.
