Polygon deployed two hard forks, Austin and Kyoto, to fix critical security vulnerabilities in its network components Bor and Heimdall. Austin addressed denial-of-service risks and potential node crashes in Bor by limiting resource-heavy operations and removing unsafe data fields. Kyoto protected Heimdall by limiting transaction complexity to prevent excessive computational load on validators. These updates were implemented quietly before public disclosure to prevent exploitation, and no attacks were reported on the mainnet. Polygon continues to enhance network security proactively to maintain performance and reliability.
