Odaily News With the official launch of Ethereum's Pectra upgrade (EIP-7702), SlowMist has issued a security reminder for users, wallet providers, developers, and centralized exchanges. Users are advised to pay attention to private key protection, cross-chain contract code differences, and delegated target risks; wallets should detect delegated chain information and prompt replay risks for chain ID 0; developers should avoid using tx.origin as a defense measure and ensure that the delegated target contract is compatible with mainstream tokens; CEXs need to track and check deposit transactions to prevent forged deposits.
