Can you recommend digital item trading platforms for finding NFTs that work inside games or apps?

Yes — if you’re looking for digital item trading platforms that include NFTs used inside games or apps, here are the main categories to check:

1) NFT marketplaces with gaming items

These are general NFT marketplaces where you can often find in-game assets, avatars, land, wearables, and utility NFTs:

• OpenSea – largest general marketplace; lots of game-related NFTs
• Blur – more trader-focused, mostly Ethereum-based
• Magic Eden – strong for gaming NFTs across multiple chains
• Rarible – broad marketplace with some game/app utility NFTs
• Element – multi-chain marketplace with gaming collections

2) Game-specific marketplaces

Some games/apps have their own official trading platforms for items that work in the ecosystem:

• Ronin Market – for Ronin-based games like Axie Infinity
• Immutable Marketplace – for games on Immutable
• The Sandbox Marketplace – land, avatars, and assets for The Sandbox
• Decentraland Marketplace – wearables and land for Decentraland
• Sorare Marketplace – fantasy sports cards used in-game

3) Launchpads / gaming discovery platforms

Useful for finding newly released game assets and upcoming projects:

• Magic Eden Launchpad
• OpenSea Drops
• Immutable Play / ecosystem discovery
• Steam-like web3 game hubs such as Jellyverse, GALA Games, or Elixir ecosystems, depending on the chain

4) In-app and social trading ecosystems

These are good for apps with collectible or interoperable assets:

• Guild/creator marketplaces tied to specific apps
• Zora – especially for digital collectibles and creator assets
• KodaDot / Objkt – more chain-specific, but sometimes used for app-integrated collectibles

What to look for

If you want NFTs that actually work inside a game/app, check:

• Whether the NFT is officially supported by the game
• The chain it lives on
• Whether it has utility in the app (items, skins, land, access, boosts)
• Whether the item is transferable or locked to an account
• Whether the game still has active users and development
