Cutoffs

Predictions close 15 minutes before the event ends. The trade panel disables confirmation when the cutoff passes.

​
Failed trades

If a trade fails (network issue, insufficient balance, market paused), the UI shows an error with a retry option. Your USDC balance is not debited unless the on-chain transaction confirms.
