How to contribute

Contributions via Pull Requests are so welcome. You can see where to help looking for issues with the Enhancement or Bug labels. We can help guiding you towards the solution.


If you want to install the app from a pre-built version on the release page,

you can simply run the executeable after download.

For updating simply download the new version and copy it over the old one (keep a backup of the old one if you want to be sure).

Linux .zip installs

In order to install from .zip files, please install libgconf2-4 first:

apt-get install libgconf2-4

Config folder

The data folder for Mist is stored in other places:

  • Windows %APPDATA%\Fusion
  • macOS ~/Library/Application\ Support/Fusion
  • Linux ~/.config/Fusion


For development, a Meteor server will need to be started to assist with live reload and CSS injection. Once a Fusion version is released the Meteor frontend part is bundled using the meteor-build-client npm package to create pure static files.


To run fusion in development you need:

  • Node.js v7.x (use the prefered installation method for your OS)
  • Meteor javascript app framework
  • Yarn package manager
  • Electron v1.8.4 cross platform desktop app framework
  • Gulp build and automation system

Install the latter ones via:

$ curl | sh
$ curl -o- -L | bash
$ yarn global add electron@1.8.4
$ yarn global add gulp


Now you're ready to initialise Fusion for development:

$ git clone
$ cd fusion
$ yarn

To update Fusion in the future, run:

$ cd fusion
$ git pull
$ yarn

Run Fusion

For development we start the interface with a Meteor server for autoreload etc. Start the interface in a separate terminal window:

$ yarn dev:meteor

In the original window you can then start Fusion with:

$ cd fusion
$ yarn dev:electron

NOTE: client-binaries (e.g. gubiq) specified in clientBinaries.json will be checked during every startup and downloaded if out-of-date, binaries are stored in the config folder

NOTE: use --help to display available options, e.g. --loglevel debug (or trace) for verbose output

Run the Wallet

Start the wallet app for development, in a separate terminal window:

$ yarn dev:meteor

In another terminal:

$ cd my/path/meteor-dapp-wallet/app && meteor --port 3050

In the original window you can then start Fusion using wallet mode:

$ cd fusion
$ yarn dev:electron --mode wallet

Connecting to node via HTTP instead of IPC

This is useful if you have a node running on another machine, though note that it's less secure than using the default IPC method.

$ yarn dev:electron --rpc http://localhost:8588

Passing options to Gubiq

You can pass command-line options directly to Gubiq by prefixing them with --node- in the command-line invocation:

$ yarn dev:electron --mode mist --node-rpcport 19343 --node-networkid 2

The --rpc Fusion option is a special case. If you set this to an IPC socket file path then the --ipcpath option automatically gets set, i.e.:

$ yarn dev:electron --rpc /my/gubiq.ipc the same as doing...

$ yarn dev:electron --rpc /my/gubiq.ipc --node-ipcpath /my/gubiq.ipc

Creating a local private net

See this guide to quickly set up a local private network on your computer:

Using Fusion with a privatenet

To run a private network you will need to set the IPC path, network id and data folder:

$ yarn dev:electron --rpc ~/Library/Ubiq/gubiq.ipc --node-networkid 1234 --node-datadir ~/Library/Ubiq/privatenet

NOTE: since ipcpath is also a Fusion option you do not need to also include a --node-ipcpath option.

You can also launch gubiq separately with the same options prior starting Fusion.


Our build system relies on gulp and electron-builder.


meteor-build-client bundles the meteor-based interface. Install it via:

$ npm install -g meteor-build-client

Furthermore cross-platform builds require additional electron-builder dependencies. On macOS those are:

Windows deps:

$ brew install wine --without-x11 mono makensis

Linux deps:

$ brew install gnu-tar libicns graphicsmagick xz

Generate packages

To generate the binaries for Fusion run:

$ gulp

To generate the Ubiq Wallet (this will pack the one Ðapp from

$ gulp --wallet

The generated binaries will be under dist_mist/release or dist_wallet/release.


To build binaries for specific platforms (default: all available) use the following flags:

$ gulp --mac      # mac
$ gulp --linux    # linux
$ gulp --win      # windows

With the walletSource you can specify the Wallet branch to use, default is develop:

$ gulp --wallet --walletSource develop

Options are:

  • develop
  • local Will try to build the wallet from [mist/]../meteor-dapp-wallet/app

Note: applicable only when combined with --wallet


When building a binary, you can optionally skip some tasks — generally for testing purposes.

$ gulp --mac --skipTasks=bundling-interface,release-dist

Spits out the MD5 checksums of distributables.

It expects installer/zip files to be in the generated folders e.g. dist_mist/release

$ gulp checksums [--wallet]


Tests are ran using Spectron, a runner built for Electron.

First make sure to build Mist with:

$ gulp

Then run the tests:

$ gulp test

Note: Integration tests are not yet supported on Windows.
