Hyper coins. You should be able to make custom sprite packs with code in some of the sprites, hyper coins are used to buy the packs, you can select some sprites, and then press the sell button if you have the developer premium
Here is a picture of what the hyper coins will look like[image: 5481b009-c21c-45b8-87b7-75962b26950e.png]
You will be able to get hyper coins from a daily spin wheel thingy to keep users more active and you can also get them if people buy your packs.
