The results for the Virtuals Protocol audit by @code4rena are in.
This time, I secured 3rd place with a solo issue found, my first ever solo finding.
A year ago, I couldn't have imagined reaching this milestone. Discipline truly is the key.

Doing a new private audit and putting into practice what I learned in the Invariant Testing Bootcamp by @RareSkills_io.
4 hours in, all good so far. Now it’s about patience, think about edge cases, and breaking as many assumptions as possible.👀

Let’s hunt all the bugs.🪲

The next era of Web3 infrastructure deserves a brand new type of security review.
For @0xPolygon's Heimdall v2 upgrade, Sherlock is bringing that model to life.

This is my @code4rena profile. I’ll always keep it as a reminder of my beginnings in Web3 security.
This incredible platform gave me the opportunity to enter this amazing world knowing nothing about cybersecurity.
Thank you for everything.💜

It’s very sad to see the history of @code4rena come to an end.
This platform will always be special to me because my first valid issue came from here.
Thank you for all the lessons and opportunities. One of the biggest names in Web3 security is leaving, we will remember you.

My first HIGH in @code4rena from the Althea Liquid Infrastructure contest.
Another small victory to add to my portfolio. Extremely pleased with the results I'm achieving.🥳
With hard work, anything is possible.

Just enrolled in the Invariant Testing Bootcamp by @RareSkills_io. 🛠️
Fuzzing is an incredibly sharp tool for uncovering those deep, edge-case vulnerabilities. The bear market is the best time to sharpen the saw and level up. Ready to get to work!

I submitted my first issue to @immunefi 2 weeks ago. It was marked invalid, so I requested mediation.
Provided a new PoC, it was verified, and the team re-engaged.
It’s been 10 days, what’s the typical response time?

New Web3 jobs: Helping with the organizational side of managing a security agency.
Interested? 📩
Apr 2
🚨 JOB ALERT 🚨
I'm looking for someone to help on the organizational side of managing a web3 security agency (part-time).
Right now, the workload is 5–10 hours weekly, but it's looking to increase.
The work includes setting up processes, managing the process of the audit (setting up repos, generating reports, ensuring quality, setting up private/internal groups, etc.), and managing our portfolio.
The person should have experience with web3 security and have an eye for detail and great organizational skills.
DM at t.me/windhustler with an example of your personal polished portfolio or web page that looks organized.

Yesterday was Halloween, but I stayed home all night auditing and working hard.
Last year, I spent it with friends, but this year my mindset has changed drastically. I want to focus on learning and improving my auditing skills.
There’s a time for growth in everyone’s life.🌱

Thank you to @BitChillApp for trusting me to conduct their security review.🫡
I’m also very grateful to @Ynyesto for the smooth communication and for being such an awesome developer.
Excited to keep working with this amazing team and see the protocol grow.

Finally, I would also like to thank @diegomazoro and @OmarLopezBTC for being part of this team; and of course, our (external) security researcher @FitroIvan for an awesome audit — communication was so smooth it felt like we'd been working together for years!

It’s wild how the brain spots tiny code changes after weeks of auditing.
Your subconscious remembers every line, and even subtle tweaks trigger alarms.⚠️
Hard work trains the brain to get sharper at any job, Web3 security is no exception.
