Safe, seamless, and smart communication between your Trézor wallet and your web browser.
Trézor Bridge® is an official communication tool developed by SatoshiLabs for connecting your Trézor hardware wallet to your computer and web browser. It acts as a secure translator between your physical device and browser-based applications like Trézor Suite.
Without the Bridge, browsers can’t communicate directly with your wallet for security reasons. This lightweight background service ensures safe and encrypted data exchange, so your private keys remain offline and protected inside your Trézor device.
Hardware wallets are designed to isolate sensitive information, such as private keys, from online threats. But when you want to access crypto apps or send transactions, your wallet must still “talk” to the web. Trézor Bridge provides a secure channel for this communication.
The Bridge handles requests like transaction signing, account verification, and device initialization without compromising your digital safety.
The software will automatically detect your device and establish a secure connection, ready for you to manage your digital assets safely.
Trézor Bridge supports all major browsers, including:
Safari may have limited compatibility due to Apple’s restrictions on local connections. In that case, the Trézor Suite Desktop App is recommended.
Security is the foundation of Trézor Bridge. Even though it enables communication between your computer and wallet, the software never has access to your private keys. Those keys remain securely stored inside the hardware device’s secure element.
Each version of Trézor Bridge is digitally signed by SatoshiLabs, ensuring authenticity and preventing tampering.
If your browser doesn’t detect the Trézor device, ensure the Bridge is running in the background. Check your system tray or activity monitor for the process named “Trezor Bridge.”
Try a different USB port or cable. Some data cables are charge-only and can’t transmit data, leading to connection failures.
Ensure your browser allows local communication and pop-ups from the Trézor website. You may also need to refresh the Bridge connection after updates.
Keep your Trézor Bridge and device firmware up-to-date. Updates include important security patches and compatibility improvements.
Some modern browsers offer WebUSB support, which lets websites communicate directly with USB devices. While convenient, it can introduce inconsistencies depending on browser policies and versions.
Trézor Bridge provides a more stable and reliable experience. It functions independently of browser changes and ensures consistent communication across platforms. For most users, Bridge remains the preferred option for connecting Trézor wallets.
Trézor Bridge® is the invisible backbone that makes secure communication between your hardware wallet and browser possible. It ensures your cryptocurrency transactions remain protected while offering the flexibility to manage your assets online.
Whether you’re a beginner or a seasoned investor, installing Trézor Bridge is one of the easiest steps you can take to enhance your crypto security. With its lightweight design, robust encryption, and ongoing updates, it continues to be a trusted tool for millions of users worldwide.
Stay safe, stay informed, and trust your hardware wallet—secured by Trézor Bridge.
