Download Trezor™ Bridge | Secure Crypto® Access

If you use a Trezor hardware wallet (such as the Trezor One or Trezor Model T) to manage your cryptocurrencies, you’ve likely encountered the term Trezor Bridge when setting up your device. Trezor Bridge is a critical piece of software that lets your computer and web browser communicate securely with your Trezor device over USB — something that modern browsers can’t do directly for security reasons.

What Is Trezor Bridge?

Trezor Bridge is a lightweight native application developed by SatoshiLabs that acts as an intermediary layer between your computer’s browser or wallet interface and your physical Trezor hardware wallet. Once installed, it runs in the background and handles secure, encrypted communication with your Trezor device, allowing you to:

  • Manage your crypto accounts
  • Sign transactions
  • Update wallet firmware
  • Interact with supported dApps

Importantly, Trezor Bridge never stores your private keys — those remain securely on your hardware device at all times. Without Trezor Bridge, your browser often cannot detect or communicate with the hardware wallet due to USB access restrictions. This is why when you plug in your Trezor, many web interfaces will prompt you to download and install Bridge first.

Where to Download Trezor Bridge

Always download Trezor Bridge from the official Trezor website to ensure you get the authentic, safe installer. Unofficial sources may contain malware or compromised software and should be avoided.

Here’s how to get it:

  1. Visit the official download page: trezor.io/bridge
    This link automatically detects your operating system and provides the correct installer.
  2. Choose your operating system:
    • Windows
    • macOS
    • Linux
  3. Download and save the installer — it will typically be a .exe, .dmg, or .deb/.rpm file depending on your platform.

Installing Trezor Bridge

Once the download is complete, the installation process is straightforward:

  • Windows: Run the .exe file and follow the setup prompts.
  • macOS: Open the .dmg file and drag Trezor Bridge to your Applications folder.
  • Linux: Use the appropriate package manager or install the downloaded package file.

After installation, restart your browser and then reconnect your Trezor device — the Bridge should now be running and detected automatically.

Using Trezor Bridge Safely

While Trezor Bridge is secure, you should still follow best practices:

  • Always download from official sources only.
  • Ensure your Trezor device’s firmware and Bridge software are up to date.
  • Avoid browser extensions or third‑party downloads that claim to provide Bridge functionality.

Physical confirmations on the Trezor device screen are required for every sensitive action — such as signing a transaction — meaning that an attacker could not steal your funds simply through a malicious Bridge installation.

Why You Might Need Trezor Bridge

Most users will need to install Trezor Bridge if:

  • Their browser does not support direct USB access to the device.
  • They are using the web version of Trezor Suite or another wallet interface.
  • Their system does not natively detect the Trezor hardware.

Once installed, Bridge enables reliable detection and communication — and lets you take full advantage of your Trezor wallet features.
