Ethereum Bridges Lose $31.7M as B² Network Halts Staking Amid Security Breaches

Woofun AI reports that AFX and the Verus-Ethereum bridge incurred approximately $31.69 million in combined losses within hours of each other, while B² Network separately suspended token staking following unauthorized access to a contract upgrade authority.

The financial impact was immediate, with the $31.69 million loss realized by July 24. AFX stated it was verifying balances and pursuing fund recovery, though no completed return of funds or finalized compensation plan had been announced.

Meanwhile, B² Network offered a manual exit route via its official Discord, promising to process ownership-verified unstaking requests within one business day.

Woofun AI data shows that structurally, the incidents highlight distinct technical failure points outside base-chain consensus. AFX’s custody and validator infrastructure, Verus’s bridge-accounting checks, and B²’s staking-contract upgrade authority each became the specific node where normal access failed.

Notably, B² did not disclose a loss amount, so its incident is excluded from the $31.69 million bridge-loss total, leaving the manual review as the sole withdrawal option until normal staking resumes.

The deeper driver is the exposure of critical security controls across these protocols. For users, the next test involves whether recovery plans successfully return funds, whether cross-chain validation verifies economic backing, and whether upgrade authority can be protected without forcing emergency exits to depend on manual intervention.
