Cross-Game NFTs: How Blockchain Assets Move Between Games

When you buy a sword, skin, or pet in a game, it usually stays locked inside that one game. But cross-game NFTs, non-fungible tokens that represent digital assets usable across multiple blockchain-based games. Also known as interoperable NFTs, they turn your in-game items into real digital property you can take with you—no matter which game you play next. This isn’t science fiction. It’s already happening in games like Dungeon Chain and Kosmic Quest, where your Dragon Coin (DGN) isn’t just a currency—it’s a key that unlocks content in other titles built on the same chain.

What makes cross-game NFTs different? Traditional in-game items are just data files controlled by the developer. If the game shuts down, your item vanishes. Cross-game NFTs live on public blockchains like Solana or Ethereum. That means you own them, not the studio. You can sell them, trade them, or use them in another game if the developers agree to support the same standard. Projects like Dungeon Chain, a blockchain built specifically for interchain gaming and SoccerHub, a play-to-earn soccer game with tokenized player assets are testing this model. They don’t just want you to play—they want you to build a collection that grows across games.

But it’s not all smooth sailing. For cross-game NFTs to work, game studios have to talk to each other. They need to agree on asset formats, balance mechanics, and how value transfers between worlds. That’s why most early examples are from the same developer or closely linked ecosystems. Still, the trend is clear: players are tired of losing their progress. They want ownership. And companies that ignore this are leaving money—and players—on the table. Below, you’ll find real reviews and breakdowns of projects trying to make this work, the ones that failed, and the ones that might just change how we play forever.
