# Abstract
MapleStory's core appeal stems from its **RX**, which is the sense of achievement and satisfaction players gain from obtaining items. Two key factors drive **RX**: **utility** and **rarity**. **Utility** indicates how versatile an item is across different situations, while **rarity** represents how limited or scarce an item is. By refining **RX**, MapleStory Universe aims to provide profound and memorable experiences that resonate deeply with players. To achieve this vision, MapleStory Universe leverages blockchain technology to enable interactions among community-created applications based on MapleStory's intellectual property (IP). MapleStory items will be created as **NFTs**, making them functional across various apps and blockchain ecosystems. This approach significantly expands the scope of use for items that were previously limited to the game itself, thereby maximizing their **utility**. The **rarity** of each **NFT** will be ensured through a predefined supply cap. **NXPC** will facilitate the creation and distribution of these limited **NFTs** through a two-way exchange system. Players can redeem **NXPC** for collections of **NFTs**, and conversely, exchange these collections back into **NXPC**. This interchangeability establishes a direct connection where **NXPC** reflects the collective utility of **NFTs**. As interest in **NXPC** grows, it naturally enhances the perceived importance of the associated **NFTs**, creating a stronger **RX** for players. To foster ecosystem growth, a **contribution mechanism** will be introduced to provide periodic **NXPC** rewards to participants who help expand MapleStory Universe. This mechanism tracks and acknowledges contributions based on **NFTs** utilization and ecosystem support. Each contributor's reward is determined by their level of contribution, applying equally to all participants, including the project team. The total amount of periodic **NXPC** rewards decreases over time, following a halving schedule similar to Bitcoin's. **NESO**, the game token of MapleStory Universe, operates with a transparent conversion rate to **NXPC**. Players can use **NESO** across various apps and marketplaces within MapleStory Universe. Contributors can integrate **NESO** into their apps as user rewards or through In-App-Purchase business models for premium content, enhancing user engagement. This flexibility allows players to earn **NESO** through in-app interactions and access additional content. **NXPC** rewards under the **contribution mechanism** will unite all community members under a common vision: enhancing **RX**. Through these collective efforts, an organic ecosystem will be created to realize the unlimited potential of MapleStory items. Furthermore, this will serve as a foundation for providing a richer and more meaningful **RX** to players. The tokenomics built on **NFTs**, **NXPC**, and **NESO**, combined with the **contribution mechanism**, will drive MapleStory Universe's self-sustainable growth. This is MapleStory Universe's unique **RX** vision, which will be realized through blockchain technology.
