Defi Kingdoms is a gamified experience in decentralized finance originally built on the Harmony blockchain. In Defi Kingdoms, players explore a pixelized world and go on in-game quests to receive rare items and resources. All characters in the Defi Kingdoms universe are represented as on-chain NFTs, which can also be traded in an open market.  Following the initial success of the Defi Kingdoms game, the platform expanded further into the Avalanche blockchain under the name Crystalvale.
