Bug found by whitehat hackers

According to a December 29 blog post from Polygon, the “critical” vulnerability in the network’s Proof-of-Stake (PoS) Genesis contract was first highlighted by two whitehat hackers via blockchain security and bug bounty hosting platform Immunefi. These hackers were given permission to detect a data breach.
