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