Karate Combat is a unique experience combining professional martial arts with gaming and Web3 technology. It features a full contact karate league with fighters from various karate styles and, occasionally, other striking-based martial arts, compete in a unique, 6.5m x 6.5m "combat pit" with 45-degree angled walls that promote continuous action.
A hallmark of Karate Combat is its innovative use of technology. Fights are streamed globally and feature immersive CGI environments created with the Unreal Engine, offering a visually distinct experience. The league is deeply integrated with Web3 technologies, and leverages the Hedera blockchain network.
This integration includes the $KARATE token, which allows fans to participate in the "Up Only Gaming" system which rewards users for wins without forcing them to wager tokens. Through a dedicated mobile app, fans vote for fighters, potentially increasing the fighters' prize pools, and earn more $KARATE tokens if their chosen fighters win, without losing tokens for incorrect picks.
Karate Combat’s unique combat system features rules emphasizing exciting, striking-based combat, with three-minute rounds and a scoring system that rewards aggression and effectiveness. It’s known for its fast-paced action, powerful knockouts, and unique presentation.

Key features include a promised average profitability of 9%, no entry or exit fees, and the ability to resell tokens at any time.
All investment projects are registered on the Hedera distributed ledger, which provides a transparent and immutable record of ownership and transactions.
