This repo is the perfect place to practice next and sharpen your skills.

@Web3_Hausa1 @PatrickAlphaC @CyfrinUpdraft Yeah, let's make Web3 safer.

In Web3, Security is a must.

[Michealking 👑 | Web3 Security Builder @BuildsWithKing]

Argus thought like an attacker… and it changed how I see my own code.

While learning from @PatrickAlphaC @CyfrinUpdraft course, I built a raffle contract. Solid, tested, and working as expected — or so I thought.

Then I ran Argus on it.

@PatrickAlphaC @CyfrinUpdraft Full report:

Still building. Still refining. Still pushing Argus to think deeper.

[Michealking 👑 | Web3 Security Builder @BuildsWithKing]

@PatrickAlphaC @CyfrinUpdraft That’s the kind of issue you don’t catch by just “testing functionality.”

You catch it by thinking like an attacker.

This is exactly what I’m building Argus to do:
Not just analyze code… but reason about how it can fail in the real world.

[Michealking 👑 | Web3 Security Builder @BuildsWithKing]

@PatrickAlphaC @CyfrinUpdraft This attack only requires the malicious contract to win. With a small number of players, the odds are far from negligible. And here’s the twist:

👉 This doesn’t even require a malicious actor.
👉 Any contract without a payable fallback can unintentionally brick the system.

@PatrickAlphaC @CyfrinUpdraft 4. The ETH transfer fails → the entire transaction reverts.
5. The raffle gets stuck in the CALCULATING state… permanently.

No winners.
No refunds.
All funds locked.

Even worse — this isn’t purely theoretical.

[Michealking 👑 | Web3 Security Builder @BuildsWithKing]

@PatrickAlphaC @CyfrinUpdraft Attack Scenario

1. An attacker deploys a malicious contract with no "receive()" function (or one that reverts).
2. That contract enters the raffle like any normal user.
3. When a winner is picked via Chainlink VRF, the malicious contract gets selected.

[Michealking 👑 | Web3 Security Builder @BuildsWithKing]

@PatrickAlphaC @CyfrinUpdraft Instead of just scanning for obvious bugs, Argus approached the contract like an adversary. It didn’t stop at “does this work?” — it asked, “how can this break?”

And what it found was subtle… but dangerous.

@only01Essential @HackenProof Congratulations @only01Essential more Wins 👏

I'd love to learn a lot from you, I know you're a very busy person , if possible please share your roadmap with me and how I can grow and identify bugs like you currently do.

Thank you so much.

[Michealking 👑 | Web3 Security Builder @BuildsWithKing]

@santipu_ Congratulations 👏🎉

Well Deserved.

@shafu0x Happy Birthday @shafu0x 🎂 my fellow celebrant.

Wishing you a long life with prosperity. May you age in grace and strength.

[Michealking 👑 | Web3 Security Builder @BuildsWithKing]

@vector_ware Thank you so much, I sincerely appreciate it.

[Michealking 👑 | Web3 Security Builder @BuildsWithKing]

+1 today.

365 days ago, I chose a hard path — programming.

Tired? I showed up.
Sick? I showed up.
Broke? I cried… then showed up.

This year broke me and built me at the same time.

I’m still going.
I’m still building.

I am a King. I am limitless.

Happy Birthday to me.

Argus caught a Critical vulnerability pattern in Compound Finance's codebase

I'll start by apologizing for announcing Argus v1.0.0
last week before it was ready. That was premature.

Today I'm announcing Argus v0.6.0-beta — live at
https://t.co/E6gff4U3wH

[Michealking 👑 | Web3 Security Builder @BuildsWithKing]

I'm looking for auditors to stress-test it. Run Argus
alongside your security research, bug bounties, and
audits — then tell me what it misses.

Static analysis: free and unlimited
Deep Analysis: AI exploit construction

Still in beta. Still improving. But it's real.
