How TayDex works
01
Create
Eligible users launch a clearly defined market with an explicit question, YES/NO rules, a deadline, and a public resolution source.
02
Trade
Any eligible user buys YES or NO shares priced by LMSR AMM. A 2% protocol fee applies to each trade. All trades settle in USDC on Base.
03
Resolve
When the deadline passes, the creator proposes an outcome with the public resolution source. Eligible users may dispute during the 24-hour review window by staking 20 USDC. The admin/contract owner reviews and confirms the final result onchain.
