In the CarboFoot application, there is a marketplace where users can buy and sell. To use the CarboFoot application, it is necessary to purchase an event ticket. In the first phase, these tickets are sold in limited numbers by the CarboFoot app. After the stock of the CarboFoot application runs out, shopping transactions take place between users.
When new user wants to do activities within the CarboFoot application, they will have to enter the in-app marketplace and purchase event tickets that other users have put up for sale.
Users can sell event tickets, levels, and carbon footprint certificates on the marketplace. Their price varies depending on the user's past activities and points earned. This means that an event ticket with a base fee of 100 BUSD can be sold for a higher price if upgraded by the owner.
