Trezor Bridge Toolkit

Trezor Bridge — Developer Guide

For developers and integrators, Trezor Bridge provides a reliable, local API surface to talk to Trezor hardware devices. Use it for building testing harnesses, wallet integrations, or for automating diagnostic tasks.

Quick start & CLI checks

Install Bridge from trezor.io/bridge. Use browser devtools to inspect requests. On Linux, check the Bridge daemon with systemctl status or process listings. On macOS and Windows, use Activity Monitor / Task Manager.

Example: Verify Bridge is listening

# Example (Linux)
ss -ltnp | grep bridge

Integration tips

  • Keep Bridge updated to match Suite and firmware.
  • Use official endpoints only; do not forward remote requests to Bridge.
  • Log all device interactions in dev environments for traceability.

Troubleshooting

Common developer issues include permission denials and port conflicts. Ensure Bridge binds to allowed interfaces and your testing browser has local host access enabled.
