DeFi Faces Renewed Pressure as Security Breaches and Sluggish Expansion Weigh on Institutional Demand
Decentralized finance is once again under pressure as recurring security breaches and slow ecosystem growth continue to undermine confidence among institutional investors.
A recent exploit tied to Kelp DAO erased nearly $20 billion from DeFi’s total value locked (TVL) within days, highlighting how quickly trust and capital can evaporate during major incidents.
The breach centered on a cross-chain bridge vulnerability, where attackers created approximately $292 million worth of unbacked rsETH tokens. Those tokens were then used as collateral on lending platform Aave to borrow genuine ETH, leaving an estimated $230 million hole in bad debt.
The fallout extended beyond directly affected protocols. Capital fled multiple liquidity pools with no direct exposure to the compromised asset, underscoring how deeply interconnected DeFi platforms can amplify risk during times of stress.
Blockchain investigators have linked the attack to North Korea’s Lazarus Group. While some stolen assets have been frozen, remaining funds are reportedly still being moved through multiple wallets and privacy-focused channels.
Security incidents across the crypto sector this year are tracking at levels similar to 2025. Although smart contract audits and protocol defenses have improved, cross-chain bridges continue to be one of the industry's weakest points.
At the same time, DeFi’s growth remains underwhelming when measured in ETH terms. While dollar-denominated TVL has mirrored broader crypto market cycles—surging through 2021, falling in 2022, and gradually recovering since—TVL adjusted against ETH prices has stayed mostly flat.
That trend raises concerns about whether DeFi can generate the kind of organic expansion needed to win over traditional financial institutions.
Recent market turbulence has also triggered a move toward stablecoins, reflecting a flight-to-safety pattern similar to investors shifting into cash during uncertain periods in traditional markets.
Among stablecoins, USDT appears to remain the preferred option during times of stress due to its deep exchange liquidity and easier off-ramp access. However, that preference has not yet translated into a major surge in its market capitalization.
Separately, on-chain data providers reported that the Kelp DAO exploit has caused a sharp liquidity squeeze across DeFi markets, with borrowing costs rising significantly.
Despite these headwinds, Bitcoin continues to benefit from steady U.S. demand and short squeeze momentum, helping support upward price action even as DeFi struggles.
