NFT release mechanics

In DeFight Club, NFT items are created through a custom ERC-1155 contract, enabling flexible handling of multiple instances, detailed parameterization, and scalable architecture. The core method is mint-on-purchase: an NFT is minted only at the moment of purchase, without pre-releasing the full supply. This approach is critical to the architecture of DeFight Club, where the potential number of unique NFTs reaches into the millions. Lazy minting is not used, as OpenSea no longer supports it, and the item structure requires strict individualization and quantitative 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,
  • enables generation flexibility: dynamic discounts, bundles, and unique series.

Integration with external marketplaces is handled via the Seaport Protocol API, ensuring secure, decentralized, and customizable NFT transaction processing.

Off-chain Items and Transition to NFT

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

  • are looted through PvE activities,
  • can be upgraded and synthesized via standard mechanics,
  • participate in market circulation without on-chain transactions.

Transition to NFT and Entry into External Markets

Items can become full NFTs only upon reaching the 6th rarity level (Unique). This allows the system to:

  • maintain control over mass issuance,
  • preserve the scarcity of truly rare items,
  • motivate players toward long-term progression and synthesis.

After transformation into NFTs, items:

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

Reverse synchronization is supported: NFTs acquired on external marketplaces appear in the in-game inventory via wallet binding and can be used in synthesis quests. This way, the in-game ecosystem is connected to on-chain markets, integrating only when value and rarity mature—ensuring economic sustainability and a sense of uniqueness for holders of high-tier assets.
