OpenZeppelin Pushes Back After Ex-CTO Declares All of DeFi Unsafe

Crypto Insight Summary: OpenZeppelin publicly distanced itself from co-founder and former CTO Manuel Aráoz after he declared on X that "all of DeFi" is now unsafe, stating his views do not represent the company and noting he departed in 2019. Aráoz argued that AI coding agents have become "superhuman" at finding vulnerabilities, creating an asymmetry where defenders must patch every bug while attackers need only one exploit, and said he has been advising friends and family to exit DeFi positions including Aave, MakerDAO, and Compound. His post drew more than 600,000 views and prompted customers to contact OpenZeppelin for clarification. In a response thread, OpenZeppelin said it has secured over $35 trillion in value transferred onchain since 2015 and that its libraries underpin most DeFi protocols. On AI, the firm acknowledged the threat but called it "one of the most powerful defensive tools we have, if used with rigor and expert human judgment," saying its researchers use AI daily to catch more vulnerabilities. OpenZeppelin reframed recent losses as primarily operational security failures rather than smart contract bugs, citing April's record 28 DeFi exploits totaling $635 million. It pointed to a StakeDAO exploit that minted 5.4 trillion tokens on Arbitrum as having stemmed from a compromised deployer private key, not a flaw in audited code. The company did not directly dispute Aráoz's claims about AI-enabled vulnerability discovery or the attacker-defender asymmetry. OpenZeppelin closed by affirming its continued commitment to securing DeFi and working alongside protocols and institutions.
