The CEO Jai Bhavnani said that the Rari team members will be sacrificing their RGT allocations and putting them towards the reimbursement and when the companies merged, Fei protocol assumed the liabilities stemming from the exploit.

We are aware of an exploit on various Rari Fuse pools. We have identified the root cause and paused all borrowing to mitigate further damage.

To the exploiter, please accept a $10m bounty and no questions asked if you return the remaining user funds.

As recently reported, Ethereum-based yield aggregator Rari Capital was attacked over the weekend by bad actors and the hackers looted 2600 in crypto in the aftermath. The attacker took place on May 8^th with a series of transactions lasting for hours. Rari Capital’s product deposits ETH into Alpha Homoras’ iBET interest-bearing token as a part of the strategy. The protocol’s pool contract operates with the ibETH.totalETH()ibETH.totalSupply() used to calculate the exchange rates for the pairs and a separate report from Alpha Finance LAbs claims that this operation can lead to incorrect assumptions. According to Alpha Finance, the ‘ibETH.totalETH() was manipulative inside the work function and the users can call any contracts if wants to inside ibETH work including the Rari capital Ethereum pool deposit and withdrawal functions.
