Frog Case is a case-opening app with a reward system where users earn stars for completing simple tasks and inviting friends. Earned stars can be spent on opening cases with stars or NFT gifts, as well as used in a digital rewards store.    Free daily cases and themed sets with different costs are available. The referral program allows users to receive additional stars for invited friends and a percentage of their activity. The profile displays balance, history, and available actions.    Frog Case combines game mechanics, collectible elements, and a reward system in a convenient and easy-to-understand format.
