Design and graphics (Qt wallet)

The cherry on the cake will be defining a unique icon and image for your newborn currency, differentiating it from Bitcoin and other cryptocurrencies.

Under the /src/qt/res directory, you'll find all the other graphical resource files that you'll need to edit, including the logo and icon (the file with an .ico extension) to personalize your graphical interface. Let's start by changing the background image that shows up when the graphical wallet is loaded. You can create a new image with a size of 1024*1024 pixels– let's say a big R in a circle with a transparent background—using Photoshop or Gimp—and save it as readercoin.png under the/src/qt/res directory. You also have to convert this readercoin.png to the svg format (readercoin.svg) using an online converter and save the result in the/src/qt/res/src directory:

When Bitcoin is run in testnet mode, the GUI uses a green image. For ReaderCoin's testnet, let's choose a different color for the background—let's say red.

The splash picture can be also converted to an .ico file to serve as an icon. You can use an online converter to get your icon file. For macOS X, you'll need to edit the Bitcoin file with the ICNS file extension.

Once you finish editing the graphical elements, you have to build the code again (by running make) to apply the graphical changes. Next time you run your ReaderCoin client's GUI, you'll see your new splash screen and icon as follows:
