The Gold is our in-game virtual money. Gold is not crypto money and can’t be listed on a decentralized exchange (DEX).
Gold price is pegged to Ether, so when Ether price goes up, the Gold price goes up.
You can buy Gold with Ether and sell Gold for Ether directly inside the game. Buying and selling Gold cost Ethereum gas fees, a few dollars per transaction regardless of the amount.

Real economy

Kingdom is based on a real economy where you need to provide services to other players for earning money.
For example, you buy a forest, produce wood and sell timber to other players. They use your wood to build a farm so you can buy food from them.
Then you can buy more forests, sell more wood, hire other players to help you and one day sell your business to someone else with a good profit.
On the contrary, most play-to-earn games or metaverse are based on a financial economy with scarce resources and monotonous mechanisms like Yield farming or staking.

How does Kingdom make money?

Kingdom sells to players: virgin tiles, virgin genesis tiles, and production plans, everything else is traded directly between players.
