Summary

On July 22–23, 2026, three separate cross-chain bridge protocols — AFX Trade, B-Squared Network, and Verus — were exploited within approximately six hours of each other for a combined loss of roughly $35.6 million. The incidents contributed to a July 2026 monthly total of approximately $97 million in crypto security losses and are part of a record-setting H1 2026 in which total hack losses surpassed $1 billion across the industry. No single threat actor has been publicly attributed to all three attacks, though the clustering prompted security firm Blockaid to label the period 'Hackers Day.'
