About Kash
Kash operates a prediction marketplace at app.kash.bot where users buy and sell shares in real-world outcomes, including sports, crypto prices, politics, technology, and cultural events. Markets use an automated market maker, settle in USDC on Base, and support multi-outcome markets, leverage, limit orders, social trading, AI-assisted market creation, leaderboards, and creator incentives. Users can trade directly through the app or reply and quote-post on X using Kash's trading account. The platform serves individual traders, creators, online communities, and business or ecosystem partners that embed or create markets.
