On February 20, 0xbrainjar confirmed that he was indeed Zaki. He wrote, "I did this so that my efforts to build up a suite of products would not be shadowed by a mistake that I made in my past.... 0xbrainjar was a place for me to not be defined by this serious misstep (which has been settled and was amplified by the media)". He also wrote on Twitter that "I do not want a mistake in my youth to cloud all of the team's efforts", though the SEC charge was filed less than three years ago, when Zaki was 21.
Composable Finance is a company that makes infrastructure tools for defi. Until recently, their head of product has been known only as 0xbrainjar, and has operated pseudonymously. However, on February 18, the crypto detective zachxbt revealed his discovery that 0xbrainjar was actually Omar Zaki. Zaki was charged with fraud by the SEC in 2019 for misleading investors while operating an unregistered investment adviser and hedge fund. He ultimately settled the case for a $25,000 fine, and a three-year ban from working in the investment industry. Although I personally think it's reasonable not to describe anything crypto-related as an "investment", I'm curious how the SEC might feel about him working on defi projects.
