Arbitrum Security Council announced that it has suspended the activation of new Stylus contracts on Arbitrum One and Nova to mitigate security risks posed by manually generated WASM programs from non-standard toolchains. According to the official statement, the known vulnerabilities may primarily lead to network performance degradation or denial of service. No attacks have occurred, and user funds remain unaffected. Activated Stylus contracts can still operate and be renewed, while the deployment and execution of Solidity and EVM contracts are not impacted. The timeline and method for resuming activations will be determined through discussions with the DAO. Additionally, this action introduces new protective mechanisms for the BoLD single-step proofs on Arbitrum One. If conflicting proofs are both accepted, Ethereum settlement may be paused, potentially delaying unconfirmed withdrawals. https://(wublock123.com)/news/arbitrum-pauses-stylus-new-contract-activation-over-security-risk-69459
