According to official news, the Ethereum Foundation announced the audit results of the Pectra system contract and disclosed that all relevant or important issues found during the review have been resolved. The Pectra system contract contains multiple EIPs (EIP-2935, EIP-7002, and EIP-7251), and the audit is mainly to evaluate potential attack vectors in the contract and to ensure that the contract logic accurately implements the expected functions in accordance with the EIP specification. The Ethereum Foundation also said that a bug bounty contest is currently being held on Cantina, with rewards for Pectra-related vulnerabilities up to $2,000,000.
