Crypto hackers have stolen $8.7 billion so far in 2026, surpassing the estimated $5.6 billion in annual onchain revenue generated across the entire industry, according to Lorenzo Valente, director of digital asset research at ARK Investment Management.
Since 2017, blockchain protocols have lost approximately 57 cents for every dollar earned onchain. Total industry losses to hacks over this period reached about $26.9 billion, while cumulative onchain revenue stood at $47 billion.
The $6.3 billion Binance hack alone exceeded Valente's full-year 2026 onchain revenue projection. Other major exploits this year include the $387 million Bitget hack in September, the $320 million Liquid Network exploit, and the $295 million Drift Protocol exploit in April.
Valente said security remains the bottleneck for the industry. The rising scale of these breaches is impacting institutional interest in decentralized finance.
Cross-chain bridges remain a significant vulnerability point. JPMorgan analysts identified bridge security as a persistent challenge for the industry in an April research note.
The total value locked in DeFi dropped nearly 10 percent since the Binance exploit, falling from $85.9 billion on Oct. 29 to $77.4 billion by Thursday—an $8.5 billion outflow from the sector.
Binance also issued a warning regarding an iOS flaw that could expose crypto wallet keys, underscoring broader security concerns within the ecosystem.
