Myriad voids 10 prediction markets after admin-wallet compromise, promises refunds

Myriad has voided 10 prediction markets after a compromise of an admin wallet, invalidating the outcomes traders had bet on. Holders on both sides will receive automatic refunds at pre-attack prices, minus any winnings they already claimed. The incident highlights smart-contract and key-management risk on prediction-market platforms, and traders should watch whether refunds are honored and whether user funds beyond these markets are affected.
