# Real Utility from Day One

RBT isn't just a speculative asset—it’s the functional currency of the Kart Rumble universe.

* Spend RBT to unlock karts, characters, cosmetics, and race entries
* Use it in the NFT marketplace for trading and upgrades
* Pay to mint tracks, enter exclusive events, and access creator tools
* Participate in tournaments and earn performance-based rewards

Every core feature of the game is tied directly to RBT, giving it a foundational role in the ecosystem from day one.
