250M+
Players across the MapleStory franchise globally, a Web2 player base that needs to onboard onto Web3 without ever feeling friction in the core game.
How Nexon brought MapleStory, a 250M-player MMORPG, onto its own L1.
Nexon, the inventor of free-to-play, is rebuilding MapleStory Universe as a hybrid Web3 game with real asset ownership, without breaking the gameplay 250M+ players already love.

The Gaming Problem
Web3 only works in MMORPGs if Web3 stays out of the way.
MMORPG economies collapse when item issuance is tuned for revenue instead of game health. Web3 games often double down by foregrounding the economy and forgetting the gameplay. Nexon needed a chain that could carry ownership without making blockchain the user experience.
20+ years
MapleStory has been live since the 2000s, the golden age of MMORPGs. Web3 features have to integrate with two decades of accumulated game economy and content.
Hybrid
Onchain ownership, item history, and randomness, offchain gameplay performance. The architecture has to give Web3 benefits without taking Web2 speed.
AvaCloud Solved the Problem
A dedicated L1 for MapleStory, with a studio-grade development pipeline on top.
Nexon evaluated the field and chose AvaCloud for enterprise-grade reliability, scale, and developer-friendly support. The Henesys L1 anchors ownership, approval logic, and verifiable randomness onchain while gameplay stays in Nexon's existing high-performance systems, a hybrid architecture that gives players Web3 ownership without taking away Web2 responsiveness.
Equally important: AvaCloud supports the way large studios actually ship. Nexon stood up dedicated dev, test, QA, and staging chains that mirror production, instead of fighting through a single shared chain with disabled gas. Each environment behaves consistently. Each team validates against realistic conditions. Updates move toward release with confidence.
The L1 also supports specialized mechanics MapleStory needs, meta transactions, Chainlink VRF-based randomness, custom approval logic. AvaCloud handles validator management, upgrades, and monitoring; Nexon's teams stay focused on gameplay, UX, and the creator-economy systems that make MapleStory Universe a platform, not just a game.
"I can't imagine a bigger opportunity in Web3 than what the Nexon Group is doing with MapleStory Universe, and we're honored to power its next blockchain project with Avalanche.", Ed Chang, Head of Gaming, Ava Labs
Architecture
Hybrid by design: onchain where ownership matters, offchain where gameplay does.
The Henesys L1 anchors what has to be verifiable, ownership, item history, randomness, approvals. Gameplay stays in Nexon's existing systems where speed and UX live. AvaCloud manages the rails underneath.

Web2 MMO vs. Hybrid Web3 MMO
Same MapleStory. Same gameplay. A different relationship to the items.
The hybrid model preserves what worked about Web2 MMORPGs and replaces the parts that didn't, specifically, the way item economies and gray markets work.
Classic MMORPG economy
250M+ players
Items live in a centralized database. Gray markets fill the gap.
- Players don't truly own anything they grind for.
- Updates pressured to print new items, fueling power inflation.
- Trading happens in opaque gray markets outside the game.
- Creator content has no portable value beyond the game.
- One environment for everyone, testing risks live players.
MapleStory Universe on Henesys L1
250M+ players
Same gameplay, plus real ownership and a transparent market.
- Players own characters, items, and gear onchain.
- Item history and randomness are verifiable, not promised.
- Transparent peer-to-peer marketplace replaces gray markets.
- Creators build worlds and content, and get rewarded for it.
- Dedicated dev, test, QA, staging chains protect the live game.

What This Delivered
The economics of running an MMORPG franchise on its own chain.
From player ownership to studio workflow, the move to AvaCloud-managed L1 infrastructure changed what's possible, and gave Nexon a sovereign foundation for the MapleStory Universe and the IPs to come.

Your gaming IP could be running this stack.
Nexon didn't bolt Web3 onto MapleStory, it rebuilt the rails for ownership, history, and randomness while leaving gameplay where it lives. Same playbook is available for any global gaming franchise, on AvaCloud-managed L1 infrastructure.
