In order to prevent the recurrence of similar incidents, Chengdu LianAn Technology warns developers that they are supposed to pay attention to the followings:
1. Be aware of whether Solidity and other official developing languages have already given the relevant built-in functions or rigorous interaction patterns. If they have, developers should abide by them and never try to create new ones.
2. Always think about whether the state variables have potential risks and lock the ones do.
3. Utilize gas limitation and commit-reveal, ensuring transaction information is revealed legitimately in corresponding steps.
