I collected relevant public available information in retrospective and worked out a timeline of the exploit. From these information combined with OP token price history, I strongly suspect there was insider trading. Insiders were aware of the exploit 2 days earlier than public disclosure.

A summary of $OP exploit timeline. Hope this explains why the incident happened and why retails got rekt (spoiler: pure incompetence of @optimismPBC and Wintermute)?

Wow, what a day.
OP Drop # 1 had a turbulent launch which we finally stabilized after more than five hours of non-stop work.
We’ll be publishing a full, detailed retrospective on the lessons learned next week. Let’s quickly talk about what happened.

@veryHighLander @optimismPBC At the time of launch, the tokens were recoverable. With the intention of exercising caution, Wintermute wanted assistance from Gnosis, but they were not available until June 07 . Wintermute notified us that someone else had taken control of the address on June 06 .

Briefly speaking, Optimism team was notified by Wintermute of the exploit on June 6 th. The disclosure came to public on June 8 th. During these 2 days, OP token price fell from $ 1 . 3 to $ 0 . 8 (BEFORE the public announcement was made). A 40 % drop within 2 days is hardly explained unless there was insider trading.

I request Optimism and Wintermute to explain:
( 1 ) Why did it take 2 additional days after the exploit to disclose the information? (meanwhile, Optimism tweeted about the airdrop retrospective on June 6 th as if nothing major happened)
( 2 ) Was there insiders who, based on information about the exploit not yet available to the public, sold OP tokens before the public announcement?
If these questions are unanswered, we cannot trust any promise on mitigation plans that Wintermute and Optimism have made.
