Three DeFi exploits drain $35.5 million within hours as AFX, Verus and B² Network hit
AI Market Summary
Three DeFi exploits drained about $35.5M across an Arbitrum USDC custody bridge (AFX), the Verus Ethereum bridge, and B² Network's B2 staking contract upgrade authority, prompting multiple pauses (bridge and staking). The clustering of bridge and privileged-access failures highlights persistent infrastructure and governance-key risk, likely worsening near-term risk appetite for DeFi protocols and cross-chain activity.
