Recently, I am learning about some contract security of Solidity, so I will post some articles about historical security vulnerabilities.

And today, We will take a look at the BeautyChain (https://www.beauty.io/) contract vulnerability that occurred in 2018.

April 29, 2025 (Beijing Time) – I just deleted all my articles from the Chinese internet. No particular reason, I just realized everything I wrote was absolute dogshit. To drastically improve the quality of my writing (or, to put it bluntly, to stop shitting all over the internet), I’ve decided to revamp my blog. From now on, I’ll only publish original, high-quality content—no more lazy copy-paste garbage filled with other people’s quotes. Oh, and I’ll probably rant about life here too. At least when I’m old and senile, I can look back and see what I was thinking. :>
