🔭O-Prediction Troubleshooting

Why can’t I see my winnings in my wallet?

When you collect winnings, they might not appear in your wallet’s transaction logs as usual. This is because they use a different type of transaction: Internal transactions.

Enter your wallet address on Etherscan, then check the “Internal Txns” tab to confirm that they’ve arrived.

Why aren't the results of my round showing?

There’s a block buffer on each round, which can cause delays after the end of a round.

This buffer is to accommodate for the fact that we may not be able to reliably fetch a price and end a round immediately: various blockchain factors affect the speed in which transactions get confirmed on the network.

I can’t collect my winnings!

Make sure you have enough ETH in your wallet to pay for gas fees. You’ll need a little ETH to trigger the smart contract.

I can't claim winnings from a prediction round on site.

You might be able to claim your winnings directly from the contract. Follow the steps in the 3 tabs below.

Check rounds you played

How to check the history of rounds you played

1. Go to the Etherscan page of O-Prediction contract

4. Click “Query”

5. Rounds you entered will show below in the first row. (after “uint256[]:”)

Check if you can claim

First, check whether you should actually be able to claim from the round you played.

1. Go to the Etherscan page of O-Prediction contract

2. Scroll down to “4. claimable”

3. Type in the round id you want to check under "epoch(uint256)”

4. Type in your wallet address under “user(address)”

5. Click “Query”

6. If a round is claimable, it will show “true”

7. If the result is "false". Please repeat the above steps and try with "19. refundable"

8. Note: ⬆️ If you see a round returns "false" on both "4. claimable" and "19. refundable", but it shows on the website, it's probably been claimed already and the website is lagging
