NFT, as a trending product in the digital media industry, has received much attention and market volumes starting from early 2021. The increasing popularity of NFT products and potential suggests that thorough research and development generate effective marketing strategies in response. Hence as a group project, we designed and implemented gamification features to NFTs to increase user engagement and fun experience while investing in such digital assets. This MRP focuses on the technology and implementation side of the project. For design and marketing, please refer to Yanbo Xing's MRP. The methodology used in this project is to evaluate reflection and iteration.After the literature review, the NFT market potentials, cryptocurrencies, mainstream token standards, and project case studies were researched and analyzed. Drawing from the reflection of initial research, design decisions were made. In execution, our project applied the design decisions and iterated from current NFT projects to compile our smart contracts to fulfill the gamification characteristics. The result is a gamified NFT loot box product prototype. Our research proves the feasibility of creating a smart contract for gamified NFT products to increase user engagement. Optimizing codes and applying such a framework to other industries will be the future goals.
