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 scale of the problem
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
On-chain ownership, item history, and randomness, off-chain gameplay performance. The architecture has to give Web3 benefits without taking Web2 speed.
A 250M-player game does not get to slow down.
MapleStory is one of the longest-running MMORPGs in the world. The fanbase is huge, the economy is mature, and the gameplay tempo is fast. Web3 features cannot be allowed to introduce a wait time. They cannot crowd out a beloved interaction. They cannot require players to learn what a private key is.
Henesys, Nexon's dedicated Avalanche L1 on AvaCloud, is engineered around that constraint. Ownership, item history, and verifiable randomness are anchored onchain. Everything else, gameplay performance, matchmaking, latency-sensitive systems, stays in the Web2 systems that already work.
What players actually feel
- Real ownership. Items players earn or trade are theirs, with verifiable history that survives the game itself.
- Player-to-player markets. Secondary markets become native, not gray-market.
- Creator economy. Outside developers can build on MapleStory's IP and economy under appropriate licensing.
What the studio gets
A studio of MapleStory's scale runs many environments. Henesys mirrors production with lightweight development, test, QA, and staging chains, so a designer can iterate on an economy change in dev without touching live player balances.
