Balancer reveals 'critical vulnerability' in some V2 pools

Quick Take

  • Balancer mitigated most of the threat, but 4% of TVL remains at risk. 
  • The decentralized exchange reported another vulnerability to liquidity pools in January of this year.

The team behind the decentralized exchange Balancer reported a "critical vulnerability" affecting some V2 pools. 

Balancer mitigated 80% of the threat but noted that the 4% of total-value-locked is still at risk, according to a Balancer forum post

"As of the writing of this post, this vulnerability has not been exploited, and no funds have been lost," Balancer wrote. "We believe funds in the mitigated pools (labeled “mitigated”) are safe, but nevertheless strongly recommend timely migration to safe pools, or withdrawal. Pools that could not be mitigated are labeled 'at risk.' If you are an LP in any of these pools, please exit immediately."

Affected liquidity pools

The Balancer UI will inform users participating in affected liquidity pools on how to withdraw their assets.

This is not the first time Balancer reported vulnerable pools. In January of this year, Balancer noted that $6.3 million worth of funds were at risk and that liquidity pools should move their funds, The Block previously reported.
