Client Wallet

To start with Coalculus and our tools, you must first download the client wallet, also known as a "wallet", on your personal computer.

Install Client Wallet on Windows

Before we start, you need to check that you have the most recent Java installed on your computer Java. Open up command prompt and type in the following.

java -version

If you receive the following output, it means you already have java installed. Otherwise, you will be required to install Java, or you have Java installed but it's PATH system variable is not properly configured.

java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) Client VM (build 25.231-b11, mixed mode)

Download the latest Java SDK here and install it.

After Java installation, you'll need to setup it's PATH system variable. Open up a file explorer and right click ‘My PC’. Select ‘Properties’.

Select 'Advanced system settings'.

Select ‘Environment Variables’.

Select ‘Path’ under ‘System variables’ and click ‘Edit’.

Click ‘New’ and enter the file location of your installed JDK. (i.e. C:\Program Files\Java\jdk-13.0.1)

Apply your new settings and restart your PC.

Repeat the first step. This time you should see the build and version number of your Java.

java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) Client VM (build 25.231-b11, mixed mode)

Download the Coalculus client wallet here.

Unzip it and move it to a folder of your choosing. From command prompt, cd to the coalculus folder and enter the command ‘run.bat’, and Java will start up the Coalculus client wallet in a new command window.

Client wallet application will open after everything is set up automatically. Or you can also access it using a browser at localhost:27876.

Note, if it's the first time you run Coalculus in your machine, the Coalculus blockchain will need to be downloaded until it is up to date.

Install Client Wallet on MacOS

Before we start, you need to check that you have the most recent Java installed on your computer Java. Open up terminal and type in the following.

java -version

If you receive the following output, it means you already have java installed. Otherwise, you will be required to install Java.

java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) Client VM (build 25.231-b11, mixed mode)

Download the latest Java SDK here and install it.

Unlike Windows, you do not need to set the system variable for MacOS, as it is done automatically, so you can simply enter 'java -version' into your terminal to check if it is installed.

java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) Client VM (build 25.231-b11, mixed mode)

Download the Coalculus client wallet here.

Unzip it and move it to a folder of your choosing. From terminal, cd to the coalculus folder and enter the command ./run.sh.

The server will start running and will be ready as soon as you see the following line in terminal log.

Open localhost:27876 from a web browser to access the Client Wallet. Please note that, if it's the first time you run Coalculus in your machine, the Coalculus blockchain will need to be downloaded until it is up to date.

Do not close the terminal as it will close the client as well.Installation Instructions for Coalculus Client Wallet on MacOS
