NFT release mechanics

NFT items in DeFight Club are created via a custom ERC-1155 contract, offering flexible handling of multiple instances, parameterization, and scalability. The core approach is mint-on-purchase: NFTs are minted only at the moment of purchase, without pre-minting the entire supply. This method is critical for the DeFight Club architecture, where the potential number of unique NFTs runs into the millions. Lazy minting is not used, as OpenSea no longer supports it, and the item structure requires strict individualization and supply control.

All token metadata and images are stored on the decentralized Arweave network, which:

  • significantly reduces gas costs at launch,
  • eliminates the need for mass minting,
  • provides flexibility in generation: dynamic discounts, bundles, unique series.

Integration with external marketplaces is implemented via the Seaport Protocol API, ensuring secure, decentralized, and customizable handling of NFT sale transactions.

Off-Chain Items and Transition to NFTs

Most in-game items initially exist off-chain (equipment, hardware modules, heroes). This model reduces network load and fees, making the economy flexible and scalable. All items:

  • are looted through PvE activities,
  • are enhanced and synthesized via standard mechanics,
  • participate in the market economy without on-chain transactions.

Transition to NFTs and External Market Access

Items can become full-fledged NFTs only upon reaching rarity tier 6 (Unique). This allows:

  • maintaining control over mass issuance,
  • preserving scarcity of truly rare items,
  • encouraging long-term player progression and synthesis.

After conversion to NFTs, items:

  • receive a unique ERC-1155 token in the collection,
  • become available for listing on OpenSea and other marketplaces,
  • appear in the player’s wallet and can be used both in-game and for trading.

Reverse synchronization is implemented: NFTs purchased on external marketplaces are reflected in the in-game inventory via wallet linking and can participate in synthesis quests. Thus, the in-game ecosystem connects with on-chain markets, tapping into them only as item value and rarity mature, supporting economic stability and a sense of uniqueness for high-tier asset holders.
