About MapleStory Universe

MapleStory Universe (MSU) is a blockchain-powered metaverse ecosystem built around Nexon’s iconic MapleStory IP. Rather than being a single game, it’s a decentralized virtual world where multiple interconnected applications and mini-games share the same assets and economic systems. All in-game items—including characters, cosmetics, and weapons—are transformed into NFTs with fixed total supplies, enabling true ownership, cross-application transfer, and player-driven marketplaces).

At its core is MapleStory N, a brand-new blockchain-infused version of MapleStory, offering item scarcity, NFT rewards, and a revamped in-game economy free of the traditional cash shop model. This is joined by MapleStory N Mobile (a mobile version with cross-platform interoperability), MapleStory N Worlds (a sandbox creation platform for user-generated content), and the MapleStory N SDK—a suite of developer tools enabling creators to design new games or apps within the ecosystem.

The broader ambition behind MSU is to pioneer what Nexon calls “Reward Experience (RX)”—a decentralized model in which players, creators, and developers are incentivized and rewarded through transparent blockchain economics. By basing the ecosystem on the NEXPACE Protocol, MSU aims to expand beyond MapleStory into a multi-IP multiverse where interoperability, user contribution, and shared governance define future value. Chainlink VRF, Avalanche (and Polygon Supernet) support ensure fast, fair, and scalable operations across the ecosystem.

About NXPC Token

NXPC is the native utility token of MapleStory Universe, a blockchain-based Layer 1 ecosystem created by Nexon to reimagine its iconic MMORPG franchise using Web3 technologies. Designed to fuel a new “Reward Experience” (RX) system, NXPC serves as the backbone of a digital economy where scarcity and utility of in-game items are preserved through tokenization. With a fixed supply of 1 billion tokens, NXPC supports item rarity and economic sustainability via NXPC Fission (exchanging tokens for NFT item sets) and Item Fusion (redeeming NFTs back into tokens), allowing organic regulation of supply based on demand.

NXPC works alongside two other elements—NFTs and NESO (the in-game token)—to maintain a balanced and interoperable economy. Its halving distribution model (similar to Bitcoin’s) gradually reduces token emissions over time, rewarding early contributors while preserving long-term scarcity. The token fuels trading, content creation, NFT utility, and even gas fees within MapleStory Universe’s blockchain. NXPC’s dynamic exchange mechanisms and cross-application interoperability ensure that game items retain significance and value across the entire ecosystem—not just within one game.

NXPC’s most ambitious goal is to evolve MapleStory into a creator-driven, community-powered economy. Developers can use the MapleStory Universe SDK to build new apps and games while earning NXPC through a contribution mechanism based on impact. As the project matures, NXPC is also expected to enable decentralized governance. Its use cases include powering NFT marketplaces, enhancing in-game strategies via dynamic reward systems, and ensuring fair, transparent token circulation. Backed by MapleStory’s global brand and 250M+ player legacy, NXPC is positioned as a pioneering example of how blockchain can enhance traditional gaming models.

Technical Details

An MEV bot (automated smart contract) spotted a significant price discrepancy for the NXPC token between two different PancakeSwap V3 liquidity pools on the BSC network. Because these pools had diverging prices—something that shouldn't persist in a healthy market—the bot performed a cross-pool arbitrage to buy low in one pool and sell high in the other. This operation resulted in a $1.2 million profit.

To ensure its transaction was executed ahead of any other bots or users who may have noticed the same opportunity, the bot paid a 97 BNB “bribe” (roughly $50,000–$60,000 depending on BNB price at the time) to the block builder or validator who produced the block containing the transaction. This is common in MEV transactions to outbid competitors in the transaction mempool or private relays.

Total Amount Lost

Profit from the arbitrage was reported as $1.2m.

The total amount lost has been estimated at $1,200,000 USD.

Immediate Reactions

The incident was reported on by TenArmor and a couple of other Twitter/X users.

Ultimate Outcome

The MEV bot gained a profit of $1.2m USD.

Total Amount Recovered

Given that this was not the result of any crime or fraud, it is unlikely to be recovered.

There do not appear to have been any funds recovered in this case.
