# NFTs Resource

GaliXCity is a PWE game that gives players many opportunities to monetize their gaming time. One of the key tricks here is being able to convert resources into NFTs. There are 4 main types of resources in the game: **Crystal, Metal, Fuel, Electricity**

Once you have accumulated enough of these resources, you can convert them into ERC-721 standard NFT items to trade in the Marketplace. NFTs package’s content allowed by the system include:

* 50,000 resource units.
* 100,000 resource units.
* 500,000 resource units.
