#Sky #Mavis has since reimbursed victims of the attack and has relaunched the #bridge with what the developers call a “circuit breaker” system that halts large or #suspicious withdrawals.

But despite these precautions, an attacker could still obtain all four of #Sky #Mavis’ keys, plus a fifth signature from #Axie #DAO to withdraw over $600 million worth of #crypto from the #bridge.

This meant that if #Sky #Mavis’s computers were taken over, the attacker still wouldn’t be able to withdraw #coins without their backing since the attacker would only have four keys.

To further ensure that the funds couldn’t be stolen, Axie #Infinity developer #Sky #Mavis distributed the majority of validator keys to other #stakeholders, including #Axie #DAO.
