What is Trezor Bridge?

h3: Role and function

h5: short summary

Trezor Bridge is middleware software that allowed Trezor hardware wallets to communicate with desktop browsers and desktop apps. It established a secure local channel between the device and web-based wallet UIs so users could manage keys and sign transactions without exposing private keys to the browser.

When & Why to use it

Historically, Bridge was required when a browser lacked direct USB support for the device. It remained useful on systems or browsers where WebUSB or native integration were not available. Over time, official apps (Trezor Suite) and direct browser APIs reduced the need for a separate Bridge installation.

Installing Trezor Bridge

Quick install steps

1. Download the installer for your OS from the official site (Windows/macOS/Linux).
2. Run the installer and follow prompts; accept system permissions if asked.
3. Reconnect your Trezor device and open your web wallet or Trezor Suite.

Tip: If you’re using Trezor Suite (official app), Bridge functionality may already be bundled or unnecessary — prefer Suite for simpler setup.

Troubleshooting

Common issues

Problems often include device not detected, driver conflicts, or browser permissions. Steps: check USB cable, try a different port, ensure no older Bridge instance conflicts, and open the official Trezor start/diagnostic pages to verify connectivity.

Security considerations

Trezor Bridge only handles transport; your private keys remain on the hardware device. Always download Bridge from official sources, verify HTTPS, and remove any third-party or outdated Bridge installations if instructed by official guidance.

Alternatives & modern workflow

Modern browsers support WebUSB and many users now rely on Trezor Suite (the official desktop/web app) or native browser integrations. If Bridge is deprecated for your setup, migrate to Suite or use a browser with WebUSB support.

Best practices

• Always use official downloads and follow vendor instructions.
• Keep Suite and device firmware updated.
• When troubleshooting, capture logs and refer to official guides before reinstalling.

FAQ

Is Bridge still required?

Requirement depends on your OS and browser. Many users no longer need Bridge if they use Trezor Suite or browsers with native WebUSB support.
