Fellow co-founder Rune Christensen paid tribute to Nikolai Muchgian, writing: "Maker would have been toast without him."
MakerDAO co-founder Nikolai Muchgian has been found dead in Puerto Rico.
He was 29 years old — and reports suggest he was swept away by sea currents on Oct. 28.
Although his body was later retrieved by rescue officials, he was showing no vital signs.
Fellow co-founder Rune Christensen paid tribute to Muchgian, tweeting:
"Nikolai was one of the only people in the early days of Ethereum and smart contracts who was able to predict the possibility of smart contract hacks and invented the security-oriented approach to smart contract design we know today. Maker would have been toast without him."
Some on Crypto Twitter have pointed to tweets that were apparently written by Muchgian shortly before his death — raising concerns about his mental health.
