Wu said that a member of the Elytro smart wallet project, @ zengjiajun_ eth, tweeted an explanation of why the Elytro wallet does not use the delegatecall method call that led to Bybit hacking attacks and its trade-offs: delegatecall is an Ethereum smart contract feature that allows one contract to run the code of another contract in its own context. In wallets like Gnosis Safe, delegatecall can directly upgrade the wallet logic in a single transaction, but this can also become a single point of failure exploited by attackers. http://(wublock123.com)/index.php? m=content&c=index&a=show&catid=6&id=38545
