Official Trézor™ Bridge® | Introducing the New Trezor®
Trezor Bridge is the hidden engine that makes using a Trezor hardware wallet with a browser feel smooth, secure, and almost effortless. For anyone serious about self-custody, understanding how Trezor Bridge works can help build confidence in every transaction.
What is Trezor Bridge?
Trezor Bridge is a lightweight desktop application that creates a secure communication channel between your Trezor hardware wallet and your web browser. Modern browsers restrict direct USB access, so Trezor Bridge acts as a local “translator” that lets Trezor Suite or web interfaces talk safely to your device.
Running quietly in the background on Windows, macOS, or Linux, it connects your plugged-in wallet over USB and makes sure requests from the browser reach the device reliably. This design improves compatibility across browsers while keeping the user experience simple and intuitive.
Why Trezor Bridge Matters for Security
The most important promise of Trezor Bridge is that your private keys never leave the hardware wallet. When you send crypto, the transaction data travels through Trezor Bridge to the device, is signed inside the wallet, and only the signed transaction goes back to the browser for broadcasting.
Even if your computer is infected with malware, the attacker cannot extract keys from the device because all sensitive operations stay isolated on the Trezor itself. Physical confirmation on the wallet’s screen adds another layer of protection, ensuring you approve exactly what you see before anything is sent.
Key Benefits of Using Trezor Bridge
- Seamless connection between Trezor devices and the Trezor Suite or web wallet interfaces.
- Encrypted, local communication that respects strict browser security rules while still enabling USB-based signing.
- Better reliability than browser-only methods, reducing connection errors and complex manual setup.
- Support for managing assets on major blockchains such as Bitcoin and Ethereum through compatible interfaces.
For anyone managing a crypto portfolio with a Trezor device, installing Trezor Bridge is not just a convenience—it is a foundational security and usability component that makes everyday self-custody safer and smoother.
