How to Dispute
Once an outcome is proposed, a challenge window opens (typically 2 hours). During this period, you can dispute the proposal on the UMA Oracle platform by posting a dispute bond equal to the proposer’s bond.Important: If your dispute is unsuccessful, you will forfeit your entire
bond. Only dispute if you are confident the proposed outcome is incorrect
according to the market’s resolution criteria.
