NFT Marketplace Integration for PC Game Windows 11

I’m ready to add blockchain utility to my existing PC game by giving players a real, on-chain trading marketplace for collectible items. The core requirement is straightforward: connect the game client to a smart-contract–powered backend so every collectible can be minted, listed, bought, and sold seamlessly without leaving the game interface.

Here’s what I need from you:
• Smart contract(s) that mint and manage the collectible items, enforce royalties, and handle secure peer-to-peer trades.
• An in-game UI module (Unity or Unreal are both acceptable) that lets players connect a wallet, browse listings, and complete purchases or sales in just a few clicks.
• A lightweight web dashboard for off-game item management and secondary sales—think OpenSea-style basics, but branded for this title.
• Full integration with the existing game logic so ownership checks, item transfers, and inventory updates happen in real time.
• Step-by-step deployment documentation and short video walk-through, ensuring my team can reproduce the setup on staging and mainnet.

Acceptance criteria:
• A player can mint a new collectible directly from the game and see it appear in their connected wallet.
• Two test accounts can list, buy, and transfer an item; the change is reflected instantly in both wallets and in-game inventories.
• All transactions show on a public block explorer with correct metadata.
• No critical contract or UI errors in a 100-trade stress test.

If you’re comfortable working with Solidity (or a comparable chain’s language), wallet APIs, and game-engine scripting, I’d love to see how you’d tackle this.
