About Kayxa - Decentralized Prediction Markets on Polygon
Kayxa was founded to make prediction markets accessible to everyone, regardless of location or financial background. Traditional prediction markets require KYC verification, bank accounts, and in many cases are restricted to specific countries. Kayxa removes these barriers by building on Polygon blockchain, enabling anyone with a crypto wallet and USDC to participate. All trades are gasless, executed by the admin wallet on behalf of users, so there are no Ethereum gas fees and no blockchain complexity for the average trader.
The Kayxa platform supports short-duration crypto price prediction markets running 24 hours a day, 7 days a week. 15-minute markets for Bitcoin, Ethereum, Solana, XRP, Dogecoin, BNB, HYPE, and MicroStrategy allow traders to speculate on whether prices will be higher or lower at the end of each window. Markets resolve automatically using Chainlink oracle price feeds on Polygon mainnet. The constant-sum AMM provides transparent pricing where YES and NO share prices always add up to 1.00 USDC. Ghost Market Maker seeds initial liquidity to ensure markets are tradeable from the first second.
Beyond crypto price markets, Kayxa offers event prediction markets covering global politics, sports tournaments, technology milestones, economic indicators, and cultural events. Community-created markets allow users to submit questions about any real-world outcome for review and listing. The platform roadmap includes longer timeframe markets, additional assets, on-chain governance mechanisms, and a fully decentralized resolution layer powered by community dispute resolution and oracle aggregation. Kayxa is committed to building an open, transparent, and accessible prediction market infrastructure on Web3.
