What is Trezor Bridge?

Trezor Bridge is a small, local application that runs on your computer and acts as a secure intermediary between your web browser and your Trezor hardware wallet. Because modern browsers limit direct USB access for security reasons, Bridge provides a safe, well-defined channel for transaction signing, address retrieval, and device management — all while keeping private keys confined to the hardware device.

Why Bridge is essential

Web-based wallets and dapps often need to communicate with a hardware wallet to request signatures or read addresses. Bridge ensures that only legitimate web origins can reach your device and that every sensitive action requires explicit confirmation on the Trezor screen. This reduces attack surface and protects funds against remote threats.

Core benefits

  • Local-only communication: Bridge runs on your computer; it does not send keys or sensitive data to remote servers.
  • Origin & permission checks: Only approved websites can request device operations, and every action must be confirmed on-device.
  • Cross-platform support: Installers are available for Windows, macOS, and Linux with clear verification steps.
  • Regular updates: Bridge receives updates for compatibility and security improvements.
  • Open resources: Documentation and developer tools are publicly available for review and integration.

Install, verify, and use — quick guide

  1. Download: Get the official installer from the Trezor Bridge page. (trezor.io/bridge)
  2. Install: Run the installer and follow the on-screen steps for your OS.
  3. Verify: Always check checksums or signatures where provided to ensure the binary is authentic. Official verification guidance is posted on Trezor documentation and support pages.
  4. Connect: Open a compatible web app such as Trezor Suite or a supported dapp and allow the browser to use Bridge to detect your device.
  5. Confirm: When an action is requested, review transaction details and confirm on your Trezor’s display — never approve blind requests.
Security tip: Only download Bridge and related software from the official Trezor domain. Avoid third-party mirrors and double-check URLs to prevent phishing.
