What is Trueo?
Trueo combines outcome tokens with a yield-bearing collateral unit. A winning token redeems for one TYD, while TYD itself represents an ERC-4626 vault position backed by USDC and powered by Yearn. Market criteria and approved data sources are committed on-chain at launch.

Pricing and total cost
The reviewed introduction and trading docs do not publish a single numeric fee schedule for every action. Inspect the swap quote and the separate proposal, oracle and vault terms. TYD yield is variable rather than a fixed cash payout rate.
