DeFi Losses Reach $7.75 Billion: Bridges Skew Risk Metrics, Highlighting Security Challenges
  • Across EVM chains and Solana, DeFi lending hacks have produced an annualized loss rate around $3 per $10,000 deposited, about 3 basis points of TVL.

  • The risk metric provides a priced, measurable sense of lending risk in DeFi, informing lenders, insurers, and allocators.

  • DefiLlama data show gross DeFi losses totaling about $7.75 billion historically, with bridges accounting for a significant portion and skewing the overall risk picture.

  • Excluding bridge incidents, cumulative gross losses reach roughly $4.52 billion in DeFi history, highlighting that bridge events disproportionately distort risk metrics.

  • Industry guidance urges diversification across DeFi lending protocols and lean, minimalistic code designs to reduce attack surfaces, with emphasis on immutability and simplicity from Morpho contributors.

  • Aave and Morpho continue to attract new lending capital, while 2026 has seen notable incidents such as the April KelpDAO breach.

  • Loss patterns show exploits often target individual components rather than entire protocols, with larger markets absorbing smaller percentage losses.

  • Recoveries reduce headline losses, totaling about 8% of gross DeFi losses across all affected protocols, and around 20% when focusing on EVM and Solana lending excluding bridges.

  • The $3 per $10,000 figure reflects historical realized losses and does not guarantee future results, as tail risks remain.

  • Trailing 12-month non-bridge lending exploits total $30.9 million gross against $99.6 billion average TVL, equating to roughly 3.1 basis points gross and 3 basis points net after recoveries.

  • Loss distributions are skewed, with a few mega-events driving most damage while many incidents are small, following a lognormal pattern.

  • April 2026 saw $606 million in hacks, driven largely by Kelp DAO and Drift exploits, marking the worst month since 2025 breach activity.
