Exchange is a building where **players can swap in-game goods 'Diamond' with KINGDOM STORY: HEROES WAR Token $KID.** If players build the exchange and connect a wallet, can exchange $KID for Diamond. And also, if players want to exchange Diamond for $KID, the exchange building should be upgraded to lv.2 or higher.
