Using a Ledger Wallet Offline

If you want to run MyCrypto offline and use a Ledger Wallet, you have to setup an HTTPS server. Fortunately, this is integrated in MyCrypto. For this guide, we will be using Node.js.

1. Installing Node.js

Start off by downloading and installing Node.js, using the installer here. It is available for Windows, macOS and Linux. After you have installed Node.js, the commands node and npm should be available from your command line.

To test this, open your command line (also called Terminal on macOS and Linux) and run the following command:

$ node -v

The $ is just an indication of a command line, do not include it in the command.

If everything goes well, you should see the version of the currently installed Node.js.

2. Getting the files we need

Download the latest version of MyCrypto, you can find it here.

Make sure to unpack it, and then execute npm install in the newly downloaded folder, this will install all the dependencies needed for MyCrypto.

Once you have the files somewhere in a folder, you need to create a self-signed SSL certificate. That may sound very technical and difficult, but all you need to do is go to this guide, and follow the steps. You should now have a server.crt and server.key file. Move these files into webpack_config/server.*.

That's it. You can now run the following command from the local MyCrypto folder to start your own HTTPS server:

$ npm run dev:https

In your browser, go to https://localhost:3000. You will see a browser warning, but it is safe to ignore this, since you are using a self-signed certificate (in Chrome: Advanced -> Proceed to localhost).
