Staking company serves Fireblocks with a lawsuit over private keys to over $75 million in ETH

Quick Take

  • StakeHound lodged a lawsuit in Tel Aviv District Court against crypto startup Fireblocks this week.
  • The complaint alleges that negligence on the part of Fireblocks contributed to the loss of private keys for more than $75 million worth of ETH.
  • Fireblocks contends it was never in charge of the keys, given the nature of its services.

StakeHound, a firm that enables staking, is suing custody service Fireblocks for allegedly contributing to the loss of private keys that accessed about $75 million worth of crypto. 

StakeHound filed the lawsuit against the Israeli-based Fireblocks in the Tel Aviv District Court. The firm claims Fireblocks' negligence led to the loss of the keys. According to the court documents reported by Calcalist, a Fireblocks employee failed to backup the keys, which were subsequently "deleted," leaving StakeHound unable to access 38,178 ETH, or more than $76 million. Those court documents also claim that the employee was working in "an unsuitable work environment," according to Calcalist.

StakeHound contracted Coincover's service as well in holding the keys, but in order for the keys to be verified, Fireblocks had to also retain a copy. In a blog post, Stakehound wrote:

"In short, a series of errors by Fireblocks caused the loss of 2 keys that are part of the 3-of-4 threshold signature for the shards that form the withdrawal key. Fireblocks (1) did not generate their private keys in a production environment, (2) did not include the private keys required to decrypt their 2 key shares in the backup, and (3) lost both keys."

But Fireblocks contends that it was never in charge of the keys. 

In a blog post published Tuesday, Fireblocks said its research team filled a request to create a set of "BLS key shares" related to StakeHound's ETH 2.0 staking project, which were managed outside the Fireblocks platform and not part of its usual wallet procedures.
