Trezor Bridge is a dedicated communication layer designed to securely connect Trezor hardware wallets to supported web applications and browsers. As a lightweight background service, it facilitates the safe and seamless exchange of data between wallet devices and online interfaces, eliminating the need for manual driver installations or complex configurations. By acting as a secure “translator,” Trezor Bridge ensures encrypted, uninterrupted transactions across multiple platforms, including Windows, macOS, and Linux, making it far more versatile and robust than browser-only methods like WebUSB.

The main strength of Trezor Bridge is its broad compatibility—it works with virtually all major web browsers such as Chrome, Firefox, and Edge, ensuring device recognition and operation regardless of browser updates. The software automatically detects when a Trezor device is connected, streamlining setup and improving day-to-day usability for both new and experienced users.

Security is foundational to Trezor Bridge. All communication between the Trezor device and computer is encrypted, so sensitive private key data remains within the hardware wallet, inaccessible to the internet or potential malware. The Bridge only facilitates the exchange of signed transaction data and user commands, effectively separating secure device functions from risky digital environments. Regular updates keep Trezor Bridge in step with the evolving landscape of browser standards and hardware capabilities, fixing vulnerabilities and adding new features as needed.

For users who value flexibility and the ability to use third-party wallets or browser-based tools without installing the full Trezor Suite, Bridge provides an essential connection while maintaining the strongest security posture. Today, as browsers phase in new APIs and deprecate older plugins, Trezor Bridge’s universal approach ensures users remain connected and protected.
