Download Trezor Bridge Go to Trezor StartTrézór Bridge®™ is a small background service developed by SatoshiLabs that enables web browsers to communicate securely with Trezor hardware wallets. It acts as a trusted link between your device and official Trezor web apps.
While the Trezor Suite desktop app does not require Bridge, some browser-based environments still use it to ensure stable and encrypted device connections.
For most users, Trezor Suite desktop is recommended. Bridge is provided as an official alternative where browser connectivity is required.
Open your browser and go to trezor.io/bridge . Always verify the URL before downloading.
Select the installer for Windows, macOS, or Linux. The file is digitally signed by Trezor to ensure authenticity.
Complete the installation and allow the service to run in the background. No manual configuration is required after installation.
Plug in your hardware wallet using the USB cable. Supported browsers should now recognize the device automatically.
Trézór Bridge®™ does not store private keys, recovery seeds, or personal data. All cryptographic secrets remain safely inside the Trezor hardware wallet at all times.
Any sensitive action—such as signing a transaction—must be physically confirmed on the device itself.
