This organization hosts what we publish for MapleStory Universe:
- Smart contract source — the contracts running the MSU on-chain economy
- Security audits — independent reviews of that code
- Official skills — tooling for building with MSU Resources
New to MapleStory Universe? Start at msu.io, or read the NXPC whitepaper.
MapleStory Universe is open to third-party builders. Start with the official docs:
- Get Started — create a Builder account, complete KYC/KYB verification, and receive an MSU Builder API key. Synergy Apps go live after a review.
- MSU Open API — characters, items, market, rewards, and OAuth 2.0
- MSU Resources — game assets through the Resource MCP server
This org hosts the agent side of MSU Resources. Once your API key and the
maple-lookup MCP server are configured
(MCP Setup Guide),
msu-skills installs the
maple-make skill into your AI coding agent — Claude Code, Cursor, Codex CLI,
and others — so it can look up real MapleStory sprites and assets while you
build.
npx skills add NEXPACE-Limited/msu-skillsnxp-contracts is the
monorepo. It covers item issuance, marketplace trading, creator rewards, and
the bridge linking Henesys — MSU's Avalanche L1, where NXPC is the
native gas token — to Avalanche C-Chain.
Seven domains:
| Domain | What lives there |
|---|---|
msu |
Game assets — equipment, consumables, characters, soulbound tokens (SBT), in-game currency |
nexpace |
Token economy — NXPC issuance, item issuance, commission, creator wallets, VRF, cross-chain bridges |
msn |
MapleStory N — collections, event store, content commission, randomness |
marketplace |
Order book and ERC-721 / ERC-1155 exchange |
multisig |
Governance multisig, owner and executor management |
util |
Access control, approval control, and execution primitives shared across all domains |
min-proxy |
EIP-1167 minimal proxy deployment |
Seven earlier per-domain repositories remain available for reference, including the commits covered by past security audits.
Core contracts have been independently audited by Hacken.
Reports are published in the monorepo under
docs/audits.
