Select your "digital highway": Select a blockchain (such as Polygon or Solana – they're well-used for games). This is where your game's unique items will reside.
Develop "smart contracts": These are similar to digital, automatic rules. You'll use them to convert your in-game items (swords, skins, property) into NFTs. That means players really do own them!
Develop the actual game: You know, the engaging bit with the graphics and gameplay.
Link everything: Connect your game to a crypto wallet so players can hold, buy, and sell their NFT items.
