"$ZEC I discovered a serious vulnerability in ZEC in late July (I have communication records with Binance customer service and the ZODL team as proof)." means that the post’s author claims to have found a major security flaw in ZEC around late July. They say they reported or discussed it with Binance customer service and the ZODL team, and that they have chat records to support this claim.

In the broader post, the author further alleges that the ZODL team updated its wallet several times after the issue was reportedly confirmed, but did not make a meaningful fix. They also say they may later publish steps to reproduce the alleged vulnerability and criticize ZEC’s technology compared with Ethereum. These are unverified claims by the author, not confirmed evidence that ZEC has an active vulnerability. $ZEC
