Trezor Bridge — Browser to Device Connector

Understanding Trezor Bridge

Trezor Bridge is a crucial software intermediary that enables secure communication between Trezor hardware wallets and web browsers. It acts as a reliable and encrypted channel that translates data safely, ensuring your private keys never leave your hardware device during transactions.

Developed to replace unsecure legacy plugins, Bridge runs silently in the background once installed, automatically detecting connected hardware and facilitating activities like account access, coins sending, and transaction signing.

Compatibility Trezor Bridge supports Windows, macOS, and Linux, working seamlessly with popular browsers such as Firefox, Edge, and Chrome. While WebUSB is preferred on Chrome and Edge, Bridge remains essential for Firefox and Safari users.

Ease of Use Installation requires a few clicks from the official website. Once running, Bridge integrates automatically with supported wallets and services, delivering a smooth crypto management experience.

Browser Support and API Evolution

Modern browsers have evolved, adopting connection protocols like WebUSB and WebHID that allow direct interaction with hardware wallets, sometimes bypassing the need for Trezor Bridge.

Google Chrome and Microsoft Edge, leveraging Chromium, prioritize WebUSB, enabling direct secure connections. Firefox and Safari currently lack full WebUSB support, relying on Trezor Bridge for device communication.

This gradual transition means Trezor Bridge’s role is shifting but remains necessary for many users depending on their browser choice and operating system.

Security and Maintenance

Trezor Bridge continuously receives updates to address emerging threats, improve stability, and maintain compatibility—ensuring secured transaction signing and wallet recognition.

Encrypted data flows prevent private key exposure.
Automatic device authentication secures transaction approvals.
Regular patches protect against vulnerabilities introduced by browser updates.

Advanced users can complement Bridge with the standalone Trezor Suite Desktop application, which connects directly to devices, avoiding browser limitations entirely.
