CoinYQ Dossier

A Billion Tokens, a Growing Item Pool

NXPC tries to make a game economy remember scarcity. It fixes the outer token budget, then lets tokens disappear into NFT sets and return through completed baskets. The elegant formula is real; so is the operator machinery that decides which items, contributions and routes enter it.

The native coin has no contract address

CoinGecko id nexpace refers to native NXPC on Henesys, MapleStory Universe’s Avalanche L1. It pays network gas and is accounted at the native-token level. The frequently copied 0x5E0E90E268BC247Cc850c789A0DB0d5c7621fb59 is the Avalanche C-Chain wrapper, so a bridge position must not be mistaken for the home asset.

On 2026-09-05 the maximum remained 1,000,000,000. CoinGecko’s supply method showed 5,447,425 at the burn address and estimated total supply of 994,552,574. Unlocked, circulating, wrapped and temporarily locked balances answer different questions.

A curve replaces the familiar loot faucet

The initial 20% is split among early community, liquidity, gas sponsorship, IP minimum guarantee, team and advisers. The other 800,000,000 follows f(n)=800,000,000×(1−e^(−0.002666n)), currently distributed in seven-day cycles. Calling it Bitcoin-like describes decay, not proof-of-work or permissionless issuance.

Code sends each week’s amount to a contributionRewardWallet. Nexpace’s measurement decides who contributed; a contract owner can change the destination wallet, pause and emergency-withdraw distributor funds. The quantity curve is automatic, while attribution and custody are governed.

Fission makes scarcity reversible

Fission exchanges NXPC for a set holding fixed percentages of every item type still available in the Item Pool. The NXPC is locked, not destroyed. If inventory empties, Fission pauses until Fusion returns items or developers introduce new types.

That distinction matters for supply charts. Fission and NXPC-to-NESO conversion temporarily remove liquid NXPC; neither is the same as a permanent fee burn. The published exchange-rate denominator even ignores burned NXPC.

Fusion needs an oracle-shaped operator

Fusion crowdsources a basket of qualifying NFTs, returns them to the Item Pool and releases the NXPC previously locked by Fission. Eligibility requires circulation thresholds, and participants split NXPC by a reference-price model.

The contracts reveal operational inputs behind the formula: basket and reward Merkle roots, round starts and emergency ends, vault addresses and executable roles. A mathematical payout can still depend on proprietary market data and roots supplied by privileged actors.

NESO and bridges create two more boundaries

NESO is not NXPC with a second ticker. It is the game-spending token, converted at a fixed disclosed rate; MapleStory N can turn contribution NXPC into NESO for gameplay rewards. NXPC remains gas and the broader contribution asset.

Warp locks native assets and mints representations on destination networks. Bridge owners can pause flows and manage relayers, and some messaging or bridge components are upgradeable. A C-Chain NXPC holder therefore carries bridge solvency, message and admin risk in addition to NXPC economics.

Audited code still has keys

NEXPACE publishes source and Hacken reports—meaningful evidence absent from many game tokens. The reports cover named repositories and commits, including multisig and contribution-distributor work. They are not permanent certification of every live address, backend, validator or later release.

One audit described the distributor owner’s ability to replace the reward wallet and emergency-withdraw, and accepted information-level monitoring gaps. The control is a design fact to monitor, not erased by the presence of an audit PDF.

Rarity is a rulebook, not an abdication

Nexpace Limited remains the website counterparty and the MapleStory live-service operator. It can update applications, approve builders, add item types, enforce game rules and discontinue website features. The whitepaper itself says its information creates no binding holder expectations.

Holding NXPC gives gas and exchange utility. It does not convey Nexon shares, MapleStory IP, dividends, a guaranteed NFT value, a right to a contribution score or a base-token governance vote. The system constrains issuance while leaving content and operations actively managed.

Evidence and primary sources

What is Nexpace?

NEXPACE is the MapleStory Universe operator; NXPC is its native Henesys gas and contribution token. NXPC Fission locks it for NFT sets, Item Fusion can release locked NXPC for qualifying NFT baskets, and Swap converts it with the separate NESO game token. Wrapped NXPC on C-Chain is a bridge representation.

What problem does Nexpace solve?

The project promises rarity without arbitrary intervention, yet a live game must add items, score contributions and operate bridges. The useful question is not whether the 1B cap exists—it does—but which scarcity rules are formulaic and which inputs remain chosen by Nexpace, contract owners and executors.

How does Nexpace work?

One billion NXPC defines the native accounting ceiling. Eight hundred million follows a decaying weekly contribution curve; the initial 200 million covers community, liquidity, gas, IP, team and advisers. Reactor moves NXPC between liquid, NFT-locked and Fusion-released states. NESO conversion and Warp add separate game and bridge layers. Owners and executors can pause, redirect rewards, publish roots, manage vaults or relayers and upgrade some components.

Key facts

  • Canonical asset: native NXPC, the gas token of the MapleStory Universe Henesys Avalanche L1; it has no ERC-20 contract address on its home chain.
  • Avalanche C-Chain bridge representation: 0x5E0E90E268BC247Cc850c789A0DB0d5c7621fb59; wrapped NXPC is a bridge claim, not another slice of the 1B native cap.
  • Maximum supply is 1,000,000,000 NXPC; CoinGecko showed 994,552,574 total after 5,447,425 at the burn address on 2026-09-05.
  • 20% forms initial ecosystem, IP, team and adviser allocations; 80% is reserved for formula-based contribution rewards.
  • Contribution emissions use f(n)=800,000,000×(1−e^(−0.002666n)) with seven-day cycles and integer rounding.
  • TGE maximum unlocked supply was 169,040,000; the Year-5 maximum is 600,005,128.
  • IP MG and team allocations have a 9-month cliff followed by quarterly vesting over 36 months; advisers have a 12-month cliff and milestone vesting.
  • Fission exchanges NXPC for NFT sets and temporarily locks the NXPC; Fusion returns qualifying baskets and re-releases locked NXPC.
  • The NFT/NXPC formula excludes burns and changes when new items enter the Item Pool.
  • NESO is a separate game token with fixed-rate contract conversion to NXPC; NXPC is native gas.
  • Contribution distribution, Fission/Fusion, bridge and game contracts expose owner, executor, pause, root, wallet, relayer or upgrade controls depending on the component.
  • Published Hacken audits are scoped snapshots, not a warranty for the entire chain and live-service economy.
  • NXPC gives no equity, dividend, MapleStory IP ownership, guaranteed floor value or base-token vote.
  • Nexpace Limited is the service counterparty; website terms select Abu Dhabi Global Market law and courts.

Frequently asked questions

Is NXPC an ERC-20 at 0x5E0…?

No. The canonical NXPC is native gas on Henesys. 0x5E0E90E268BC247Cc850c789A0DB0d5c7621fb59 is the Avalanche C-Chain bridge token.

Is supply fixed at one billion?

The maximum native accounting cap is 1,000,000,000. Burns lower total supply; Fission and NESO conversion can temporarily lower liquid supply, while wrapped balances represent locked native NXPC.

Who receives weekly emissions?

The formula sets the weekly amount, then a contributionRewardWallet receives it for attribution. Contract ownership and Nexpace contribution measurement remain control points.

Does Fission burn NXPC?

No. It locks NXPC while NFT sets leave the Item Pool. Item Fusion can release that NXPC when qualifying NFT baskets return.

Is every MapleStory NFT redeemable?

No. Special or partnership items may be outside Fission/Fusion, sets depend on available inventory and Fusion baskets require eligibility thresholds.

Is NESO the same asset?

No. NESO is a separate game token convertible at a fixed disclosed rate. NXPC is native gas and the broader contribution asset.

Do audits remove admin risk?

No. Hacken reviewed specified snapshots. Owners and executors still operate pause, emergency withdrawal, reward wallet, roots, relayers and upgrade controls in relevant contracts.

What legal rights does NXPC confer?

Utility does not equal equity. Reviewed terms provide no Nexon shares, MapleStory IP, dividend, floor value, guaranteed contribution reward or base-token governance vote.
