The Ethereum Foundation’s Protocol Security team said AI agents can help uncover real vulnerabilities in protocol code, but warned that the hardest part is not generating bug reports. It is proving which ones are real.

The Protocol Security Team has been pointing AI agents at Ethereum’s protocol code. Our core takeaway wasn't about finding bugs, it was about triage.

Here are field notes from the work.https://t.co/HVtc8XcrJK

In a new post, the team described how it has been running coordinated AI agents against systems Ethereum depends on, including systems software, cryptographic code, and contracts that require high assurance.
