Sport.Fun is a blockchain-based fantasy sports and prediction platform on the Base chain, enabling users to own and trade fractional shares of real-world athletes (e.g., in football/soccer and NFL), build squads, compete in skill-based tournaments using official data (Opta/Sportradar), and earn Tournament Points (TP) for rewards and pack openings. It features a hybrid economy with non-token gameplay (TP and Gold/USDC) separated from the optional $FUN token for enhanced utilities, generating revenue from transaction fees to fund buybacks for sustainability and growth across multiple sports.
