Item Fusion is a mechanism designed to facilitate the exchange of MapleStory NFTs for NXPC.

Participants collaborate to complete a 'basket', a predefined collection of items, and receive NXPC rewards for their contribution. This mechanism serves a vital role in the ecosystem, functioning as an automated stabilizer that regulates item circulation based on ecosystem demand.

• For comprehensive details on mechanics and usage, please refer to:

  1) Item Fusion App

  2) Item Fusion User Guide

Submission: Once a round opens, you can submit items to help fill the basket. Be sure to check the ‘Est. Rewards Per Item’ beforehand to identify which items offer the best reward.

• Withdrawal Rules: You can withdraw items 5 minutes after submission, provided the basket is not yet full. Once the basket is 100% full, withdrawals are PERMANENTLY DISABLED for settlement.

Settlement: Once the basket reaches 100%, settlement begins. Your submitted items are EXCHANGED for NXPC. This process takes time to finalize, and you will be notified upon completion. Please be aware that this process is irreversible, and you lose ownership of your submitted items.

• Claim Rewards: After settlement is complete, your rewards become available on ‘My Page’. Rewards do not expire, so you can claim them at your convenience.

Note: Final rewards may vary slightly from estimates due to decimal truncation.

• Next Round: A new round will begin following a short cooldown period. You can join the next round once it opens.

Item Fusion requires a Credit Level of 2 or higher. If your Credit Level is currently 1 or 0, you cannot participate in Item Fusion. For more information, please refer to Credit Level documentation. (Link)

If your Credit Level drops after submission: You can still withdraw previously submitted items and claim rewards after the round ends, but you cannot submit additional items until your Credit Level is restored.

You lose ownership of your submitted items once settlement is complete. They are returned to the Item Pool, a repository where limited MapleStory Universe items are stored, effectively removing them from circulation.

Yes. Items in the Item Pool may eventually re-enter circulation through Fission (NXPC redemption). However, specific items cannot be targeted for retrieval, as the lineup of available items is determined by the protocol.

A basket is a predefined collection of specific NFTs filled collaboratively by participants. The composition is determined by the following three criteria.

• Item Pool Inclusion (Fundamental Rule): Only items registered in the Item Pool are eligible candidates. Items that are not governed by the Fission and Fusion mechanisms cannot be included in a basket.
• Quantity Requirement (Based on Max Supply): The number of items required for each type is calculated as a fixed percentage of its maximum supply.

• Example: If the requirement is 1% of Max Supply:

  * Item A (Max Supply 1,000): Requires 10 units.

  * Item B (Max Supply 2,000): Requires 20 units.

• Circulation Threshold (Minimum Liquidity): An item type is eligible only if its current circulating supply is sufficient. Specifically, the circulating supply must be at least 50 times the quantity required by the basket.

  * Example: If a basket requires 10 units of Item A, there must be at least 500 units of Item A circulating in the market for it to be eligible. 

The basket composition is finalized at the start of the round and remains fixed throughout the active phase. Any updates to eligibility or quantity requirements are calculated during the cooldown period and applied to the subsequent round.

Items cannot be withdrawn for 5 minutes after submission. You can check the exact withdrawal availability time in the withdrawal modal.

After the 5 minutes lock-up, you may withdraw items only if the basket is still filling. Once the basket is full, withdrawals are permanently disabled. Submitted Items will be exchanged for NXPC and cannot be retrieved.

On the Fusion web, go to the ‘Item Basket’ list and select the ‘Submitted’ filter. You can view only the items you have submitted.

You can check the ‘Est. Rewards Per Item’ to view the projected payout for a single unit.

Important: Item enhancements do not affect your reward. Attributes such as Bonus Stats, Star Force, Potential, and Bonus Potential are ignored. All items of the same base type receive the exact same reward. For example, whether you submit a “Neophyte Ring” with Legendary Potential or a clean, basic version, the reward amount will be identical.

Please note that final rewards may vary slightly from the estimates due to decimal truncation.

Rewards become available immediately after settlement is complete. You can view and claim your NXPC in the following locations:

• Item Fusion → History
• My Page → Total Claimable

Note: The History and My Page menus are unavailable during Round 1 and become accessible after Round 1 ends.
 

The ‘Est. Rewards Per Item’ indicates the projected NXPC allocation for a single unit. This figure is calculated based on the item’s relative market value within the completed basket. Put simply, the higher an item’s value compared to the total basket, the larger its share of the total rewards.

[Key Terms]

• Item Reference Price: The estimated market value of a specific item type, systematically derived from marketplace data. It employs a proprietary valuation model designed to reflect prevailing market conditions while filtering out statistical anomalies and mitigating short-term volatility.

• Total Basket Value: The sum of the reference prices for all items required to fill the basket.
  Calculation Example: Let’s assume the Total Rewards pool is 40,000 NXPC.

  * Calculation Example: Let’s assume the Total Rewards pool is 40,000 NXPC.

• Basket Composition

  * Item A (1 unit): Reference Price 10,000 NXPC

  * Item B (2 unit): Reference Price 12,000 (Total 24,000 NXPC)

  * Total Basket Value: 10,000 + 24,000 = 34,000 NXPC

• Item A Reward Calculation: Item A accounts for approx. 29% of the basket’s value (10,000 / 34,000). Therefore, it receives that proportional share of the Total Rewards.

  * (10,000 / 34,000) x 40,000 ~= 11,764 NXPC.
   

The Total Rewards pool is determined by the NFT/NXPC Exchange Rate. This rate is not arbitrarily set but is dynamically derived from the ecosystem’s supply ratio.
 

Formula: NFT/NXPC Exchange Rate = (Total NFT items remaining in Item Pool) / (NXPC Total Supply)
 

Example:

• If there are 1,000,000 items in the pool and the Total NXPC supply is 100,000, the Exchange Rate is 10 (meaning 10 items are required for 1 NXPC).
• In this scenario, if a Fusion basket contains 100 NFTs, the Total Rewards generated for that basket would be 10 NXPC (100 / 10).

No. Rewards are not newly minted. They are sourced from the reserve of NXPC accumulated via Fission (Redeeming NXPC for NFTs).

When users spend NXPC to acquire items (Fission), that NXPC is temporarily locked. Fusion releases this locked NXPC back into circulation as users return items to the Item Pool. This cycle allows Fission and Fusion to work together, maintaining a balanced item supply based on demand.
