Trezor Bridge — Secure Connection for Your Trezor™

Trezor Bridge — This guide explains how to download and install Trezor Bridge, configure it for Windows/macOS/Linux, troubleshoot common Trezor Bridge issues, and keep Trezor Bridge working securely for long-term use.

Trezor Bridge — What is Trezor Bridge?

Trezor Bridge — Trezor Bridge is a lightweight local transport application that allows your computer browser or desktop apps to communicate securely with your Trezor hardware device. Trezor Bridge ensures that web-based interfaces and Trezor Suite can reliably detect and operate your Trezor by bridging USB/Bluetooth communications to the browser via a local service for Trezor Bridge.

Trezor Bridge — Why Trezor Bridge Matters

Trezor Bridge — Without Trezor Bridge, many browsers cannot access USB-connected Trezor devices directly. Trezor Bridge provides secure, signed communication and compatibility across platforms, making Trezor Bridge essential for firmware updates, transaction signing, and safe account management.

Trezor Bridge — Platforms Supported

Trezor Bridge — Trezor Bridge supports Windows, macOS, and many Linux distributions. Trezor Bridge installs a local service and driver (where required) so apps like Trezor Suite or web wallets can connect to your device. Use the official Trezor download page to get the correct Trezor Bridge installer for your system.

Trezor Bridge — How to Download & Install Trezor Bridge

Trezor Bridge — Start by visiting the official Trezor website and navigate to the Trezor Bridge download section. Choose the appropriate Trezor Bridge package for your operating system, download it, and follow the on-screen installer prompts to complete the Trezor Bridge installation.

  • Trezor Bridge — Windows: run the .exe installer and allow system permissions when prompted for Trezor Bridge.
  • Trezor Bridge — macOS: open the .dmg and drag the Trezor Bridge app to Applications; grant permissions if macOS requests Trezor Bridge network access.
  • Trezor Bridge — Linux: use the provided package or repository instructions to install Trezor Bridge and start the local service for Trezor Bridge.

Trezor Bridge — Configure and Use Trezor Bridge

Trezor Bridge — After installation, ensure the Trezor Bridge service is running. Open your browser or Trezor Suite and check device detection. If your Trezor is not detected, verify USB cables, grant necessary permissions, and confirm that Trezor Bridge appears as an active local service for Trezor Bridge.

Trezor Bridge — Many browsers will prompt for permission to connect to the Trezor Bridge local host address; accept those prompts to allow Trezor Bridge to function. If your environment blocks local connections, configure firewall or security settings to permit Trezor Bridge communications.

Trezor Bridge — Troubleshooting Trezor Bridge Issues

Trezor Bridge — If Trezor Bridge does not detect your device, try the following steps to resolve Trezor Bridge connectivity problems quickly and safely.

  1. Trezor Bridge — Restart the Trezor Bridge service or reboot your computer to clear transient issues with Trezor Bridge.

Trezor Bridge — Security Considerations for Trezor Bridge

Trezor Bridge — Trezor Bridge runs locally and only opens connections to the localhost. To keep Trezor Bridge secure, always download Trezor Bridge from the official Trezor source, verify provided checksums or signatures, and avoid third-party packages that claim to provide Trezor Bridge functionality.

Trezor Bridge — Keep your operating system updated and restrict network-exposed services; Trezor Bridge does not require internet access for basic device communication, but firmware updates via Trezor Suite will need a secure internet connection.

Trezor Bridge — Advanced & Developer Notes for Trezor Bridge
