The firm Has been working With various security groups to conduct audits of its protocol, and The vulnerable code had been reviewed and approved during an external audit. However, The vulnerability persisted on-chain for eight months before it was exploited, despite a $1 million bug bounty.

Sherlock, an audit group that had previously collaborated With Euler Finance, verified The root cause of The exploit and assisted Euler In filing a claim. The audit protocol voted on The claim for $4.5 million, Which was approved, and a $3.3 million payout was later made on March 14.
