Ethereum-based layer-two scaling network Polygon has quietly fixed a vulnerability that put almost $24 billion worth of its native token, MATIC, at risk.

According to a Wednesday blog post from Polygon, the “critical” vulnerability in the network’s proof-of-stake Genesis contract was first highlighted by two whitehat hackers on Dec. 3 and Dec. 4 via blockchain security and bug bounty hosting platform Immunefi.
