Create a currency that can only be used in that world. You can earn money by bundling currencies and selling them as currency packages.
After creating a currency in the studio, it can be used normally only when the integration work in Unity is completed.



## Currency

'Currency' refers to all goods used in the world. Currencies can be packaged into currencies and sold for ZEM.

- Currency packages sold as ZEM become revenue that can be directly exchanged.
- User DB related to currency can be viewed and edited in 'Balance' in the 'Data Management' menu.

When creating a currency, the required information is as follows.

- Currency ID: This is a unique identifier for the item. Only lowercase letters (a-z) numbers (0-9) and special characters (\_) (.) can be used.
- Currency name: This is the currency name exposed to users.
