# Items exchange

Players will be able to exchange items while in the city and interact with other players or make a request for an exchange with other players in certain institutions of the city. For exchange items, you will need to use $MEL token.

At the start it will be focused on Upgrade Points, with the following trading categories:

* Weapon Upgrade Points <> $BLL
* Costume Upgrade Points <> $BLL
* City/Area/Business Upgrade Points <> $BLL

Players will earn a disproportionate share of the City/Area/Business Point rewards and will earn a disproportionate share of the Weapon Upgrade Point rewards. For getting the Upgrade Points that they need most, they will be able to trade with each other.
