In November 2025, Balancer experienced a major attack with total losses reaching $116 million. The white hats, the internal security team, and StakeWise collectively recovered about $28 million.

StakeWise will independently manage the nearly $20 million it recovered.

Cyvers CEO Deddy Lavid called the Balancer incident one of the most complex attacks of 2025.

The Balancer community is working to establish a fair compensation mechanism, aiming to help victims recover a reasonable portion of their losses. The incident once again demonstrates that multiple audits cannot fully eliminate vulnerabilities. As attack methods evolve, strengthening contract security and risk management remains a challenge for the DeFi sector.
