Sarcastically, Mr. Galka identified, the hacker was following Beanstalk’s said guidelines. The issue is there was no contingency for anyone taking on the voting mechanism, which displays the novelty of the undertaking itself, he mentioned.

“The whole lot this man did was according to the code,” Mr. Galka mentioned.

Publius, the event group that launched Beanstalk, declined to remark for this text.

The developer group has been making an attempt to regroup and has mentioned it needs to aim to rebuild. To take action would require securing the protocol, discovering new capital to fund it, in addition to repaying customers who misplaced cash from the hack.
