Ganache is your personal blockchain for Ethereum development.

Getting started

You can download a self-contained prebuilt Ganache binary for your platform of choice using the "Download" button on the Ganache website, or from this repository's releases page.

Ganache is also available as a command-line tool. If you prefer working on the command-line, check out the ganache CLI.


Please open issues and pull requests for new features, questions, and bug fixes.


  • node v14.21.1

To get started:

  1. Clone this repo
  2. Run npm install
  3. Run npm run dev

If using Windows, you may need windows-build-tools installed first.

Building for All Platforms

Each platform has an associated npm run configuration to help you build on each platform more easily. Because each platform has different (but similar) build processes, they require different configuration. Note that both Windows and Mac require certificates to sign the built packages; for security reasons these certs aren't uploaded to github, nor are their passwords saved in source control.

On Windows:

Building on Windows will create a .appx file for use with the Windows Store.

Before building, create the ./certs directory with the following files:

  • ./certs/cert.pfx - Note a .pfx file is identical to a .p12. (Just change the extension if you've been given a .p12.)

In order to build on Windows, you must first ensure you have the Windows 10 SDK installed. If you have errors during the build process, ensure the package.json file's windowsStoreConfig.windowsKit points to your Windows 10 SDK directory. The one specified in the package.json file currently is what worked at the time this process was figured out; it may need to be updated periodically.

Because Windows requires a certificate to build the package -- and that certificate requires a password -- you'll need to run the following command instead of npm run make:

In order to successfully sign the appx bundle on Windows 10, an alternative signtool.exe to the binary bundled with electron-builder may need to be used. See electron-userland/electron-builder#6817.

Install Windows SDK 18362 from, and set the signtool path for electron-builder as follows:

$env:SIGNTOOL_PATH='C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x64\signtool.exe'

note: Newer versions of the SDK may not work, as the default value for the /fd (file digest) argument was no longer supported (electron will exclude the argument if digest is SHA1 [the default] when spawning signtool.exe, see While older versions do not support the SIGNTOOL_PATH environment variable.

$ CERT_PASS="..." npm run build-windows

Replace ... in the command above with your certificate password.

This will create a .appx file in ./out/make.

On Mac:

Building on a Mac will create a standard Mac .dmg file.

Before building on a Mac, make sure you have Truffle's signing keys added to your keychain. Next, run the following command:

$ npm run build-mac

This will create a signed .dmg file in ./out/make.

On Linux:

Building on Linux will create a .AppImage file, meant to run on many versions of Linux.

Linux requires no signing keys, so there's no set up. Simply run the following command:

$ npm run build-linux

This will create a .AppImage file in ./out/make.

Generating Icon Assets

Asset generation generally only needs to happen once, or whenever the app's logo is updated. If you find you need to rebuild the assets, the following applications were used:

Two tools were used:

electron-icon-maker generates assets for all platforms when using Electron's squirrel package, and these assets live in ./static/icons. svg2uwptiles generates all assets needed for the Windows appx build, and those assets live in ./build/appx. These locations can be changed in the future, but make sure to change the associated configuration pointing to these assets.

Note from the author: I found managing these assets manually -- especially the appx assets -- was a pain. If possible, try not to edit the assets themselves and use one of the generators above.

Flavored Development

"Extras" aren't stored here in this repository due to file size issues, licensing issues, or both.

Non-ethereum "flavored" Ganache extras are uploaded to releases here:

When "extras" change they should be uploaded to a new release, and a corresponding Ganache release that targets the new ganache-flavors release (see common/extras/index.js for what you'd need to update)

VS Code Debugging

Below is a .vscode/launch.json configuration that will attach to both the main and renderer processes. You only need to run the Launch Ganache UI configuration; the renderer attach configuration will run automatically.

  "version": "0.2.0",
  "configurations": [
      "name": "Attach to Renderer Process",
      "port": 9222,

      "name": "Launch Ganache UI",
