This guide explains Trezor Bridge: why it was created, how it works, installation steps, common problems and modern alternatives. Use these 10 short sections as a slide deck or a single-page reference for walkthroughs and team training.
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.
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.
Tip: If you’re using Trezor Suite (official app), Bridge functionality may already be bundled or unnecessary — prefer Suite for simpler setup.
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.
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 Always download Bridge from official sources, verify HTTPS, and remove any third-party or outdated Bridge installations if instructed by official guidance.
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.
Requirement depends on your OS and browser. Many users no longer need Bridge if they use Trezor Suite or browsers with native WebUSB support.
Official documentation and downloads are the authoritative source for installers and deprecation notices. Use the official Trezor pages for downloads and upgrade paths.
