The crypto lending market has staged a strong recovery, with total value locked climbing more than 55% since July to approximately $56 billion, according to DeFiLlama. The rebound follows a difficult second quarter, when the sector lost $11.33 billion, according to Galaxy, partly because of the Kelp DAO exploit that rippled through Aave users and exposed risks in interconnected DeFi protocols.
In April, an exploit targeting Kelp DAO's cross-chain infrastructure allowed attackers to create 116,500 unbacked rsETH tokens, worth roughly $290 million at the time. Some of those tokens were then used as collateral to borrow funds on Aave. Although Aave's smart contracts were not directly compromised, the protocol saw deposits fall by nearly $15 billion and froze its rsETH and wrsETH markets. Stani Kulechov, founder of Aave Labs, said security in crypto must also cover the bridges, oracles, and external systems on which collateral assets depend. Aave has begun reviewing each asset quarterly and announced a gradual wind-down of operations across six networks that failed to meet its standards.
Aave has also incorporated artificial intelligence tools into its security processes. During a test of the V4 version, its systems detected 271 of 304 deliberately introduced vulnerabilities. In a separate review of V3 and V4 code, three AI tools flagged 71 potential issues, but only 20 were confirmed as valid after manual assessment. Kulechov warned that around 70% of initial AI findings were false positives, making human oversight essential. Shawn Owen, CEO of SALT Lending, noted that key management, access controls, and social engineering remain major sources of cryptocurrency losses. Thomas Wu, chief financial officer of Ledn, recommended keeping clients' Bitcoin in segregated custody and reducing unnecessary transfers to limit exposure to attacks.
Separately, Ethereum co-founder Vitalik Buterin warned about the risks AI poses to cryptographic security. He urged users not to rush funds into new wallets, while stressing the need to address vulnerabilities in both quantum and AI-accelerated cryptography. His commentary, which received more than 7,600 likes and 1,300 retweets, added to broader concerns that rapid AI advances could undermine established cryptographic algorithms faster than expected. No major price movements were reported, but traders are watching for new cryptographic standards and security protocols in response to these threats.
