Myriad Markets' internal wallet was compromised; 10 prediction markets have been invalidated and refunds issued.
On October 26th, the internal wallet of Myriad Markets, a prediction market within the BNB Chain ecosystem, was compromised. The attackers manipulated the results of 10 prediction markets. Myriad Markets has recovered the funds, invalidated the affected markets, and refunded both long and short positions based on the final prices before the attack, deducting any fraudulent gains already received. Affected markets included predictions regarding whether Base would issue its token in 2026, the US midterm elections, crypto and commodity prices, and George Russell's potential victory in the 2026 F1 Drivers' Championship. Myriad Markets will attribute the vulnerability to a third-party library used by its backend services. (Source: The Defiant)
