The Mist browser is the tool of choice to browse and use Ðapps.

For the Mist API see

This repository is the Electron host for the Meteor-based wallet dapp.

You can also help by responding to issues. Sign up on CodeTriage and it'll send you gentle notifications with a configurable frequency. It is a nice way to help while learning.


If you want to install the app from a pre-built version on the release page, you can simply run the executable 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 depends on your operating system:

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


For development, a Meteor server assists with live reload and CSS injection.

Once a Mist version is released the Meteor frontend part is bundled using the meteor-build-client npm package to create pure static files.


To run mist in development you need:

  • Node.js v7.x (use the preferred installation method for your OS)
  • Meteor javascript app framework
  • Yarn package manager

Install the latter ones via:

$ curl | sh
$ curl -o- -L | bash


Now you're ready to initialize Mist for development:

$ git clone
$ cd mist
$ yarn

To update Mist in the future, run:

$ cd mist
$ git pull
$ yarn

Run Mist

For development we start the interface with a Meteor server for auto-reload etc.

Start the interface in a separate terminal window:

$ yarn dev:meteor

In the original window you can then start Mist with:

$ cd mist
$ yarn dev:electron

NOTE: Client binaries (e.g. geth) specified in clientBinaries.json will be checked during every startup and downloaded if out-of-date, binaries are stored in the config folder.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 Mist using wallet mode:

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

Connect your own node

This is useful if you are already running your own node or would like to connect with a private or development network.

$ yarn dev:electron --rpc path/to/geth.ipc

Passing options to Geth

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

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

The --rpc Mist 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 path/to/geth.ipc the same as doing...

$ yarn dev:electron --rpc /my/geth.ipc --node-ipcpath /path/to/geth.ipc

Creating a local private net

If you would like to quickly set up a local private network on your computer, run:

geth --dev

Look for the IPC path in the resulting geth output, then start Mist with:

$ yarn dev:electron --rpc path/to/geth.ipc


Our build system relies on gulp and electron-builder.


Cross-platform builds require additional electron-builder dependencies.

$ brew install rpm
$ brew install wine --without-x11 mono makensis
$ brew install gnu-tar libicns graphicsmagick xz

Generate packages

To generate the binaries for Mist run:

$ gulp

To generate the Ethereum 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 master:

$ gulp --wallet --walletSource local

Options are:

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 the distributables.

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

$ gulp checksums [--wallet]

Cutting a release

  1. Install release globally:

    $ yarn global add release
  2. Create a git tag and a GitHub release:

    $ release <major|minor|patch>
  3. A generated release draft will open in the default browser. Edit the information and add assets as necessary.


Tests run 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.
