DeFi suffered 88 hacks with known dollar amounts in Q2 2026, with total losses of $780.3 million through June 30. April accounted for $644.8 million, while May and June added a combined $135.4 million across dozens of incidents. Bridge-related hacks were tagged at $353.4 million, and DeFi protocol-targeted entries made up $735.8 million of the quarter’s total, according to DeFiLlama’s hacks tracker.
