Trezor User Env

This environment is meant to support Trezor development - both Firmware and Suite and other related projects. Its main goals are:

• Provide an easy websocket server that is capable of:
  • Launching/stopping different versions of the firmware emulator.
  • Launching/stopping trezord-go (Bridge).
  • Send simple debug commands to the emulator.
• Enable full integration testing of Suite, firmware emulator and Bridge using the websocket server.
• Provide a HTML page that communicates with the server. This allows the developers to perform the actions above.
• To be Nix-native but also offer Docker image to allow non-NixOS developers to use it.

How to run

You can also run trezor-user-env "natively" if you are on NixOS but we mainly support the Docker way as described here.

In case you have installed Trezor Bridge previously there will be a port conflict, please make sure it is not running. Either uninstall it completely or stop the service.

Supported platforms are Linux and macOS (both Intel and Silicon).

Prerequisites

• Docker (on Linux, you need to be able to run it as non-root user, follow those steps)
• xhost on Linux
• XQuartz on macOS. Configure > Preferences > Security > Allow connections from network clients
• Reboot (sign out/sign in might work)

Steps

1. Clone this repo and enter the directory
2. Run ./run.sh it will determine your platform and launch trezor-user-env. See ./run.sh --help for some additional arguments.
3. Open http://localhost:9002.

Basic terminology

• Controller
  • Websocket server running on localhost:9001
  • Has the functionality to control trezor components (run emulators, bridges, etc.)
  • Used by Dashboard (below) or by automated end-to-end tests in Trezor Suite
• Dashboard
  • HTML page being accessible on localhost:9002
  • Instructs the websocket server what to do by predefined functionality
  • Used by developers testing their firmware/suite applications manually
• Bridge
  • Service running on localhost:21325
  • Connection between the trezor device (or running emulator) and the host
  • Used by applications needing to communicate with trezor device (for example Suite)
• Bridge proxy
  • Proxies requests to the bridge
• Bitcoin regtest
  • Bitcoind with blockbook running in regtest mode
  • Default credentials for bitcoin backend
    • user and password: rpc/rpc and that you can run
  • You can test the connection with bitcoin-cli -rpcport=18021 -rpcuser=rpc -rpcpassword=rpc -getinfo

Development

See docs/development.md.

Troubleshooting

• On Apple Silicon Macs, trezor-user-env-regtest runs in an emulation layer as there is no arm native image. You may experience some slowness or issues when using it on arm Macs.
