What is Trezor Bridge?

Trezor Bridge is a small but critical program that runs in the background of your computer. It serves as the vital link between your Trezor hardware wallet, which secures your private keys, and the applications you use to manage your crypto, such as Trezor Suite or other compatible third-party services. Without Trezor Bridge, these applications cannot detect or communicate with your Trezor device.

Why Trezor Bridge is Necessary

Trezor devices use a low-level communication protocol to ensure the highest level of security. Standard web browsers and operating systems do not natively support this protocol. Trezor Bridge translates the communication, acting as an intermediary to allow your browser or a local application to talk to your Trezor device securely. This setup maintains the "air gap" security model, where your private keys never leave the hardware device, even during transactions.

Secure, Encrypted Communication

Trezor Bridge uses secure, end-to-end encrypted channels to communicate with your Trezor device. This means that all data exchanged is protected from eavesdropping and tampering, ensuring that your transactions and personal data remain private and secure.

Open-Source and Audited

Like the rest of the Trezor ecosystem, Trezor Bridge is open-source. This allows the global security community to constantly audit and review the code for vulnerabilities. This transparency is a cornerstone of our security philosophy and a key reason why Trezor devices are considered the gold standard in hardware security.

Seamless User Experience

While Trezor Bridge provides a crucial security function, it is designed to be invisible to the user. Once installed, it runs in the background, requiring no further interaction. This allows you to focus on managing your crypto with the smooth, intuitive experience of Trezor Suite, knowing that your connection is always secure.

Frequently Asked Questions

Do I need Trezor Bridge to use my Trezor?

Yes. Trezor Bridge is a small, essential piece of software that must be installed on your computer to allow web browsers and applications to communicate with your Trezor device. This is a security feature to ensure that the communication between your computer and the device is properly handled and secured.

Is Trezor Bridge a wallet itself?

No, Trezor Bridge is not a wallet. It is simply a communication tool that enables your Trezor hardware wallet to connect with software interfaces like Trezor Suite. It does not store your private keys, seed phrase, or any cryptocurrency. Your assets are always stored securely on your physical Trezor device.

Can I use Trezor Bridge with other wallets?

Trezor Bridge is specifically designed to work with Trezor devices. While some third-party web wallets may be compatible, its primary function is to facilitate the connection for Trezor Suite, which is the official and most secure way to manage your Trezor device.

How do I know if Trezor Bridge is running?

Trezor Bridge runs as a background process. On Windows and macOS, you can often see a small icon in your system tray or menu bar. If you open Trezor Suite and it detects your device, you can be sure that the Bridge is running correctly.
