Blockchain security firms such as Halborn, Solidified, ZK Labs, Certora, Sherlock, and Omnisica conducted Euler Finance smart contract audits from May 2021 to September 2022.
Halborn made its risk assessments by weighing the probability of a security event and its impact with risk levels ranging from very low and informative to critical.
In his recent Twitter thread, Bentley said he’d never “forgive the attacker” as he was forced to “sacrifice time” with his newborn son due to the attack but thanked security experts who are “working on leads” for the investigation.
Euler issued a warning just 24 hours before the bounty, warning that if 90% was not returned within 24 hours, it would launch a bounty "that leads to your arrest and the return of all funds."
