PANews reported on November 6th that due to a vulnerability in Balancer V2, the fixed-rate lending protocol Notional V3 lost a total of 721.6 ETH on the Ethereum mainnet and Arbitrum. Balancer/Aura leveraged vault users suffered a 100% loss, and ETH lending and liquidity provider accounts will experience significant write-downs. To prevent further risks, Notional V3 announced it will shut down services on both chains and automatically migrate cross-currency lending users to Aave. The official statement indicates that detailed write-down percentages and exit strategies will be released soon, urging affected users to contact the team as soon as possible.
