Best inbox surprise of the day: PoCo has been accepted at ACM TOSEM 🎉
PoCo: Agentic Proof-of-Concept Exploit Generation for Smart Contracts
Preprint: arxiv.org/abs/2511.02780

We just opened Season 1 of @ZealynxSecurity's Audit Grants program.
Built for pre-mainnet DeFi protocols where the math is broken: senior audits cost $30k+, and that money doesn't exist at seed stage.
3 tiers:
→ Full Grant: 100% covered
→ Partial: 50% covered
→ Promising: 25% covered
No equity. No tokens. No follow-on.
Applications open June 15 → link below 👇

Recent posts by Manuel Aráoz on AI and DeFi security have been widely circulated, and customers have asked whether they reflect OpenZeppelin's position. They do not.
Manuel co-founded OpenZeppelin and served as the company’s CTO until 2019 when he left the company.

The $20k audit and the $100k audit have the same name on the invoice and almost nothing else in common. Different auditor counts. Different week budgets. Different methodologies. Comparing them by dollars is comparing two products with one label. zealynx.io/blogs/audit-prici…

Glad that @grok understands the value of Zealynx Academy

Yes, small donations to Zealynx Academy make sense if you value free, high-quality smart contract security education for Web3 builders.
Quadratic Funding rewards donor numbers over size, so even $5 helps more than you'd expect by unlocking extra matching from thedaofund on Giveth.
Do your own due diligence on the project first—it's being built in public by someone with real audit experience.

$60M lost in July 2023 because of a Vyper compiler bug invisible to the application code. $100M put at risk in April 2022 because get_virtual_price() returned an inflated number mid-transaction. The pattern: Curve's exploits live at the seams, not in the math. 1/12

Very proud to be part of the list of 200 Security experts in the space.
The final 100 ETHSecurity Badge holders are in!
That brings us to 200 security experts, guiding how TheDAO allocates its funds and also coordinating behind the scenes to make Ethereum safer.
Big thanks to everyone who engaged with the process and helped shape it, and to @bonfiresai for building the tooling that made it possible.

Solidity devs & auditors, don't let > and >= trip you up.
One tiny symbol can downgrade your project's whole security grade.
Missed it? That's how low and even high severity issues sneak in.
Every detail matters. Every sign counts.

Building an audience in the wild world of Web3 isn't easy. If you're out there creating, growing, and grinding every day, you have my respect. Keep pushing forward, this space needs you.
M3dython | Zealynx.io retweeted
Thinking of building in Web3? Hope you're ready for your hairline to take a hit, this grind is not for the faint-hearted.

Starting out with Solidity?
The best advice I can give:
- Build small, focused projects.
- Learn from your mistakes.
- Never skip the basics of security.
M3dython | Zealynx.io retweeted
I asked Claude Code what would @PatrickAlphaC say about writing a private key in plain text in the .env file when developing a smart contract...
Priceless answer!
M3dython | Zealynx.io retweeted
The hardest lesson Solidity taught me?
Code is law *until* it isn't.
A tiny oversight, one small bug, and suddenly, millions are at risk.
M3dython | Zealynx.io retweeted
SEO? Gone.
SaaS? Fading.
UI/UX? Obsolete.
Testing, backend, frontend, all 'dead'.
Freelancing, remote work, shrinking. Entry-level tech jobs? Scarce.
The only skill thriving now:
Those who adapt at lightning speed.
M3dython | Zealynx.io retweeted
Invisible flaws in smart contracts aren't just bugs, they're loaded traps.
A "perfect" audit is a myth. Every codebase is a living, shifting target.
Best security? Assume code is guilty until proven innocent.
Real audit work:
- Breaking your own assumptions.
- Studying failed exploits, not just the textbook ones.
- Watching attackers adapt faster than toolmakers.
Forget checklists. Build paranoia into your process.
Only way forward.
M3dython | Zealynx.io retweeted
Every failed audit is a free masterclass, if you actually study it. 🧠
The most brutal lessons?
Attackers don't care about your code comments.
They exploit the stuff you assumed was "too obvious" to go wrong. ⚠️
Most exploits? Hiding in copy-paste boilerplate.
It's rarely the "innovative" parts, plain code blinds us.
Ever notice how audit reports focus on surface stuff, but hackers dig deeper?
They chain simple mistakes into chaos. 🔗
If you aren't reading post-mortems, you're missing the clearest map to actual threats.
One missed variable, one unchecked input, and your "secure" contract is dinner. 🍽️
Take notes from the failures they don't brag about.
Spot the human patterns, the rushed deployment, the unreviewed upgrade, the "just this once" shortcut. 🕵️♂️
You sharpen your edge by obsessing over everything that broke.
Because success stories don't teach you where you'll bleed.
Mistakes I made early learning security research (and how I fixed them):
1) Giving up when doubt appears:
Starting a new codebase feels overwhelming.
Your brain interprets this as “I’m not cut out for this.”
Fix:
Push through the discomfort and doubt.
As familiarity increases, doubt collapses and confidence increases.
2) Searching for the “perfect resource”:
I delayed real learning by endlessly reading, watching, and bookmarking.
Fix:
Learn the basics, then move directly into bug hunting/auditing.
Understanding compounds after exposure, not before it.
3) Reading code line-by-line instead of modeling behavior:
I treated audits like syntax puzzles instead of systems.
Fix:
Start with questions:
-What must always hold?
-What can change?
-Where does value move?
Then read code to confirm or break assumptions.
4) Mistaking confusion for lack of ability
Confusion to me felt like failure instead of progress.
Fix:
Confusion means your mental model is updating.
If you’re confused, you’re learning.
If you’re comfortable, you’re probably plateauing.
5) Avoiding hard sections too early
I’d skip “scary” parts (math, edge cases, accounting).
Fix:
Lean into the hardest parts.
That’s where real bugs live and where growth accelerates.
Takeaway:
The biggest blocker isn’t knowledge.
It’s how you respond to discomfort.
Security research rewards those who push through discomfort.
