Small footprint — designed to run quietly in the background without draining resources.
Stable API
Well-documented local endpoints let web apps integrate reliably across browsers.

FAQ
Is Bridge safe to run?
Yes — Bridge runs locally and communicates directly with your Trezor device. Always download Bridge from official sources, verify checksums/signatures, and keep your firmware updated.
Do web apps see my keys?
No. Private keys never leave your Trezor device. Web apps only receive signed responses after you approve actions on the hardware device.
Troubleshooting
If Bridge fails to connect, try restarting the service, use a different USB port/cable, or reinstall. Consult the official troubleshooting docs for platform-specific steps.
