The secure communication layer between your browser and Trezor hardware wallet
Trezor Bridge is a lightweight background application that enables secure communication between your Trezor hardware wallet and web-based applications. It acts as a trusted connection layer, allowing your browser to interact with your Trezor device without exposing sensitive information such as private keys.
When using web wallets, exchanges, or blockchain services that support Trezor, Trezor Bridge ensures that all cryptographic operations are handled safely on the device itself. This design keeps your private keys offline and protected from malware or unauthorized access.
Modern browsers have limited access to hardware devices for security reasons. Trezor Bridge solves this limitation by acting as a secure intermediary. It allows supported websites to communicate with your Trezor wallet while maintaining strict security boundaries.
Trezor Bridge runs as a local service on your computer. When you visit a supported website, the site sends a request to Trezor Bridge rather than directly to your hardware wallet. Trezor Bridge then forwards this request securely to your device.
Any sensitive action—such as signing a transaction or verifying an address—must be confirmed physically on your Trezor device. This ensures that even if a website or browser is compromised, attackers cannot perform actions without your approval.
Trezor Bridge is mainly required when you use your Trezor wallet with web-based interfaces instead of the Trezor Suite desktop application. Examples include web wallets, decentralized applications, and certain third-party crypto services.
If you are using the Trezor Suite desktop app, Trezor Bridge is usually not required, as the application communicates directly with your device. However, for browser-based access, Trezor Bridge ensures compatibility and security.
Installing Trezor Bridge is simple and only takes a few minutes. It is available for major operating systems including Windows, macOS, and Linux.
Once installed, Trezor Bridge runs automatically in the background and requires no further configuration for most users.
While both Trezor Bridge and Trezor Suite are official tools developed by Trezor, they serve different purposes. Trezor Suite is a full-featured application for managing your crypto portfolio, while Trezor Bridge is a background service focused solely on communication.
Many users prefer Trezor Suite for everyday use, as it offers enhanced privacy, integrated features, and a modern interface. Trezor Bridge remains essential for users who rely on web platforms and browser-based tools.
Trezor Bridge follows strict security standards and is regularly updated to address new threats. It does not collect personal data or track user activity. All communication between the browser and the device is encrypted and limited to authorized requests.
To stay safe, users should always ensure they are using the latest version of Trezor Bridge and accessing only trusted websites that officially support Trezor hardware wallets.
Occasionally, users may experience connection issues with Trezor Bridge. These are often resolved by restarting the service, reconnecting the device, or refreshing the browser.
Trezor Bridge plays a vital role in enabling secure interaction between your Trezor hardware wallet and web-based crypto services. By acting as a trusted communication layer, it preserves the core security principle of keeping private keys offline.
Whether you are accessing decentralized applications or managing assets through supported web platforms, Trezor Bridge ensures a safe and reliable connection. Combined with strong security practices, it helps protect your digital assets in an increasingly connected world.
