“We have a problem,” said Moses. Synthetix, the synthetic asset protocol that Warwick, Moses, and their team had been building for over two years, had fallen victim to a crippling exploit: an attacker with the pseudonym “Onyx” had created $11 billion of synthetic asset debt — over 275 times what Synthetix was worth — and was taunting team members and sowing chaos in public channels. These days, time and success seem to have tempered what Warwick freely admits is a fiery disposition. Still witty and pugnacious, he’s prone to ribbing his competitors and critics on Twitter, but otherwise presents as affable and charming; sometimes even wise.
