What is TayDex?

TayDex is a prediction exchange on Base. Eligible creators define a binary question, deadline, trading window, resolution rules, and a public source before a market opens. Eligible users review those terms and trade Yes or No outcomes in USDC through an LMSR AMM, with a 2% protocol fee per trade. Each market links to its settlement source and a verified Base contract. Market creation is limited to eligible users, and the product is available to adults where lawful.
