It enables holders to engage in DAO governance and staking rewards, offering voting rights and rewards for staking. This involvement shapes the game's development. In the Rainbow Marketplace, RBW is crucial for purchasing items, boosters, and materials, enhancing gameplay and providing additional resources. Additionally, RBW is vital in breeding and evolving Unicorns, the central characters of the game. This process allows for the creation of new characters and the enhancement of existing ones, adding depth to the game. Overall, RBW's diverse roles in governance, marketplace transactions, and character development make it a fundamental component of the game's ecosystem.
