The AI Audit Agents are becoming better and better. If you want to test out Nethermind's AA, here's the link
$2.2Bn were stolen last year. Could AI make our code safer and reduce hacks? I spent last week and tested various AI auditors. In this video I'll answer how to use them in prod? And could machines finally replace human auditors today?. 2 AI auditor system: .SavantChat &

Why do I say this???.Because if you are just getting into Web3 Security today, you will literally have a MUCH HARDER TIME to "MAKE IT". Does this mean you should give up or that you don't have the skills?.Absolutely not. It's just that the environment is harder. Keep grinding.

Check out the public report. These two "issues" were deemed valid Mediums in this contest. [M-02] Return values of ERC20 transfer and transferFrom are unchecked.[M-07] Using transferFrom on ERC721 tokens.

In today's public competitive landscape this is not even considered anymore, this would be "at best" a design choice to avoid the potential DoS. No one takes you seriously if you submit this "finding" today, yet someone got paid a "Solo Mid" for this finding back in 2021.

- Weird ERC20s are usually out of scope.- A lot of "known issues/design choice" invalidations.- Borderline Mediums usually get downgraded to Low severity. Don't take my word for it, check this report where someone got awarded a valid Medium on C4 for this.

Web3 security public competitions in 2021:. - Using transferFrom instead of safeTransferFrom == valid Medium on Code4rena. Web3 security public competitions in 2025:. - Admins never make mistakes even if the code is wrong and they could theoretically make them.

I worked at Chainstack for over a year and I can confirm that NOTHING beats their pricing model, and quality :).
Y'all know the answer, it starts with "chain" and ends with "stack" ππ οΈ.

This sums up "the trenches" pretty well.
