Dispute
Safeguard fair outcomes and get rewarded - empowered by $OPN
Opinion is built on the principle that market outcomes must be accurate. The dispute system gives every participant the power to challenge a resolution they believe is wrong — creating a transparent, community-driven layer of accountability.
By allowing anyone to dispute, Opinion ensures:
Accuracy — incorrect resolutions can be corrected before payouts are finalized.
Fairness — every trader has a voice.
Accountability — disputors who are right are rewarded; frivolous disputes are discouraged through staking.
Summary
Any user can dispute a market resolution during the dispute window by staking $OPN tokens.
Two dispute categories: Wrong Result (the outcome is incorrect) or Too Early (the event hasn't happened yet).
You may also provide a detailed written reason — including reference URLs or evidence — for review.
One dispute per resolution. The first user to file a dispute claims the slot. Once a dispute is filed, no further disputes can be submitted for the same resolution.
If your dispute is accepted: you receive your stake back plus an equal reward in $OPN.
If your dispute is rejected: your stake is forfeited.
The required stake amount is shown on each market's dispute page.
Gas policy: you pay your own gas for filing a dispute and claiming your reward.
How It Works
Step 1 — A Market Resolves
When the proposed outcome is published and a dispute window opens - typically 2-hour long except some asset-price related markets. During this window, payouts are not yet finalized.
Step 2 — File a Dispute
If you believe the resolution is incorrect, you can file a dispute directly from the respective market page:
Select your dispute reason: Incorrect outcome or Too early to resolve.
Optionally, provide a detailed explanation with supporting evidence (e.g., links to news sources).
Stake the required amount of $OPN tokens. You will need to connect your wallet and have the required amount of $OPN ready. The exact amount is displayed on the market page.
Confirm the on-chain transaction.
Step 3 — Review
Once a dispute is filed, a review process will take place.
Step 4 — Outcome
No dispute filed
Resolution auto-finalizes after the dispute window expires
N/A
Dispute in review
A dispute has been filed and is currently under review — result pending
Held
Dispute rejected
The original result is reaffirmed — it stands
Forfeited
Dispute accepted
Original resolution is overturned — new result is applied
Returned + equal reward
Time out
Dispute succeeds automatically; market can be re-resolved later
Returned + equal reward
Step 5 — Claim Your Reward
If your dispute succeeded (accepted or timed out), you can claim your stake and reward from the market page. This is an on-chain transaction — you pay gas to claim.
Timelines
Each market has its own dispute window durations. These are displayed on the market page when a resolution is proposed.
Dispute window — the period after a resolution is published during which you can file a dispute.
Review window — the period after a dispute is filed for a review process. The dispute automatically succeeds if the review process times out.
Stake & Rewards
Stake token: $OPN
Stake Requirement
The required stake amount is fixed at the time the first resolution is proposed for a market, and is calculated as:
max(1% of market open interest, 1,000 $OPN)
The $OPN amount is determined using the Binance OPN/USDT exchange rate at the time the first resolution is proposed.
Example (assuming OPN/USDT = 1):
200,000 USDT
2,000 $OPN
2,000 $OPN
50,000 USDT
500 $OPN
1,000 $OPN (minimum floor applies)
The exact stake amount is always displayed on the market's dispute page before you commit.
Note: Opinion reserves the right to adjust the stake percentage based on market category.
Reward structure:
Dispute accepted or timed out: you receive your full stake back, plus an equal reward — 2x your original stake in total.
Dispute rejected: your entire stake is forfeited.
FAQ
Q: How do I know if I can dispute a market? A: When a market has an active dispute window, the market page will show the dispute option along with the remaining time and required stake amount.
Q: What $OPN tokens do I need? A: You need $OPN tokens in your connected wallet (EOA). The exact amount required is shown on the market's dispute page.
Q: What happens if no one disputes? A: The resolution is automatically finalized after the dispute window expires, and payouts proceed as proposed.
Q: Can I dispute more than once on the same market? A: No. Each resolution allows only one dispute. Once a dispute is filed, no additional disputes can be made.
Q: What's the difference between "Incorrect outcome" and "Too early to resolve"? A: Choose Incorrect outcome if you believe the outcome is incorrect. Choose Too early to resolve if the event the market is based on hasn't actually occurred yet — for example, a match that was postponed.
Q: Do I pay gas fees? A: Yes. Dispute actions — filing a dispute and claiming your reward — require you to pay gas on the BNB Smart Chain.
