Q2 2026 DeFi hacks hit $780.3 million across 88 incidents, turning yields into a hidden liquidity tax
AI Market Summary
Q2 2026 data showing $780.3M in known DeFi hack losses reframes yield as a risk-adjusted return problem, with infrastructure surfaces (bridges, oracles, frontends, signing) acting as a recurring "liquidity tax". This can tighten on-chain liquidity, widen spreads, raise insurance and incentive costs, and shift routing toward venues with clearer security assumptions. The narrative increases scrutiny of DeFi connectivity risk rather than isolated protocol bugs.
