# NFT Usage Concept

**NFT as Proof of Investment:**<br>

After investing in a project, the investor receives an NFT that defines their rights to a share of the game’s revenue or other benefits. This NFT can also indicate the investor’s tier level and privileges on the platform.

**SBT for Age Verification:**<br>

Soulbound Tokens are issued for user identification (e.g., to access premium content) after completing KYC/AML processes.

**NFT for Limited Editions:**<br>

Developers can issue collectible NFTs (game keys, exclusive content, or characters) that users can own but cannot resell, ensuring a direct link between the owner and the game.
