| Resolution | Optimistic oracleUMA's optimistic oracle settles markets created since March 2026: a bonded proposal, a challenge window, then a UMA token-holder vote if disputed. Recurring up/down crypto markets settle from Chainlink Data Streams. Its technical overview describes a simplified adapter with no bond or dispute, which contradicts the help pages. | AI panel, human appealOpinion AI proposes the outcome from predefined sources, then a jury of models and human reviewers check it. Anyone can dispute within the window, usually two hours, by staking OPN: an upheld dispute returns twice the stake, a rejected one loses it. |

You trade on BNB Chain and want a low fee at 50¢ with yield on your open positions.

Pick Opinion if
You want macro and political markets on BNB Chain with the cheapest taker fee at 50¢.
A BNB Chain venue built around macro and political markets, with the lowest maximum taker fee in the series, 1% at 50¢, and an AI oracle whose results anyone can dispute by staking its OPN token. Its January 2026 volume drew public questions about wash trading, and DefiLlama filters flagged wallets out of its figure.
