The MEV builder has returned approximately 920 ETH, valued at around $2.7 million, to Makinafi's recovery multi-signature wallet following a recent exploit. The incident, which occurred on January 20, resulted in the loss of approximately 1,299 ETH, equivalent to $4.13 million. Despite the partial recovery, about 276 ETH of the total amount remains with a Rocket Pool Validator. The return of the funds marks a significant step in the recovery process for Makinafi, as efforts continue to retrieve the remaining assets.
