The Arbitrarum Security Committee temporarily blocked the activation of new Stylus contracts on the Arbitrarum One and Nova networks at 07:30 (UTC+8) on October 3rd. This restriction applies to programs and application updates that require new activation. Activated Stylus applications will continue to run, while regular Solidity contract deployment and execution will not be affected. Arbitrum officials stated that this preventive measure stems from the threat of WebAssembly program attacks against non-standard Stylus compiler toolchains. Currently, no risk of fund theft has been found, and the main concerns are on chain activity and denial of service (DoS) attacks.
