Attackers exploited a critical integer underflow flaw in the Cosmos EVM framework across six blockchains, resulting in a $5.7 million token theft. Delays and communication gaps in issuing a security patch and coordinating upgrades among independent validators worsened the impact.

This Wire brief sits within Fusion42's coverage of Crypto & Web3, and 2 sources have reported it between 29 Aug 2026 and 30 Aug 2026.

◆ ◆ The Wire takeaway
