Arbitrum has announced the successful implementation of the latest ArbOS 32 upgrade on the Arbitrum One, Nova, and Sepolia networks. The upgrade adds security by patching node crashes caused by malicious contracts, excessive fees charged by Stylus contracts, and denial-of-service (DoS) attacks resulting from pricing errors for certain transactions. The team of Arbitrum is committed to providing the best possible experience for developers and users on the platform, and the ArbOS 32 upgrade is a testament to that commitment.
