SlowMist Releases Pectra Upgrade (EIP-7702) Security Alert to Beware of Cross-Chain Replay and Delegate Call Risks

On May 8th, with the official launch of the Ethereum Pectra upgrade (EIP-7702), SlowMist released security reminders for users, wallet providers, developers, and centralized exchanges. Users are advised to pay attention to private key protection, cross-chain contract code differences, and the risk of delegation targets; wallets should detect the delegation chain information and prompt the replay risk of the chain ID being 0; developers should avoid using tx.origin as a defense and ensure that the delegation target contract is compatible with mainstream tokens; CEX needs to track and check deposit transactions to prevent counterfeiting deposits.
