Trezor Bridge: Connecting a Trezor Hardware Wallet
Trezor Bridge: Connecting a Trezor Hardware Wallet
Trezor Bridge was a background communication application that allowed Trezor hardware wallets to communicate with Trezor Suite and supported web browsers. Trezor has now deprecated the standalone Trezor Bridge and recommends using the newer connection methods built into Trezor Suite.
Trezor Bridge was developed to create communication between a Trezor hardware wallet and compatible computer software. It operated in the background, allowing supported applications and browsers to detect and communicate with a connected Trezor device.
For current users, however, the standalone Bridge is no longer supported. Trezor recommends moving to the current Trezor Suite connection system.
In most current setups, you do not need to install the standalone Trezor Bridge.
Trezor has moved away from the standalone Bridge and recommends using Trezor Suite's current device-communication functionality. For the web version of Suite, supported Chromium-based browsers can use WebUSB to communicate with the hardware wallet.
For a current Trezor setup:
Download Trezor Suite from an official Trezor source.
Install and open Trezor Suite.
Connect your Trezor hardware wallet using a suitable USB data cable.
Follow the instructions shown by Trezor Suite.
Unlock your device when requested.
Review wallet and device information.
Confirm important actions directly on the Trezor device.
Trezor recommends using the latest supported software rather than relying on deprecated components.
Trezor Suite is now the primary software environment for managing compatible Trezor hardware wallets. It provides tools for viewing accounts, managing supported assets, sending and receiving cryptocurrency, and configuring device settings.
The standalone Bridge should not be confused with the current communication functionality used by Trezor Suite. Trezor's documentation specifically identifies the standalone Bridge as deprecated.
If Trezor Suite does not recognize your hardware wallet, Trezor recommends checking the physical connection first.
Try the following:
Use a high-quality USB data cable.
Reconnect the Trezor device.
Make sure the device firmware is current.
Restart Trezor Suite.
Check whether security software or a VPN is interfering.
Use a supported operating system and browser.
Follow Trezor's official troubleshooting instructions.
Trezor notes that an unsuitable USB cable is a common cause of connection problems; a cable that powers the device may not necessarily support data transfer.
Trezor currently recommends uninstalling the standalone Bridge because leaving it installed may interfere with future Trezor Suite releases.
The removal procedure depends on your operating system. Trezor provides separate instructions for Windows, macOS, and Linux.
Only use Trezor software obtained from official Trezor sources. Avoid downloading cryptocurrency wallet software or hardware-wallet utilities from unofficial websites.
Most importantly:
Never share your recovery seed.
Never give your PIN to another person.
Never enter recovery words into a website.
Be cautious of fake Trezor support accounts.
Verify the website address before connecting your device.
Confirm important transactions on the physical Trezor device.
A person claiming that your Trezor needs a “Bridge update” should not automatically be trusted. Check the request against Trezor's official documentation first.
Trezor Bridge was a background program that enabled communication between Trezor hardware wallets, Trezor Suite, and supported browsers.
No. Trezor states that the standalone Bridge is deprecated and recommends uninstalling it.
Use the current Trezor Suite connection functionality. For the supported web version, compatible Chromium-based browsers can communicate with the device using WebUSB.
Check your USB data cable, firmware, software version, operating system, and browser compatibility. Trezor recommends troubleshooting the physical connection first.
No. Avoid unofficial downloads. Trezor recommends using its official software and supported connection methods.
Trezor Bridge was an important component of earlier Trezor wallet setups, but the standalone Bridge is now deprecated. Current users should rely on the supported Trezor Suite connection methods instead.
For the safest experience, keep Trezor Suite updated, use a reliable USB data cable, obtain software from official Trezor sources, and never disclose your recovery seed or device PIN.
