Update: Well I was not the one who broke. I found a critical bug on @immunefi #immunefitribe https://t.co/gYfjxH1vlo
A few months ago. I got tired of manually calculating results in Cantina competitions before they actually ended. Competitions with complex results could take an hour to calculate. So I actually created a script to automatically do it for me. Here is the latest updated version…
I compiled the statistics of my web3 security journey over the past 10 months—$124,678 across five vulnerability classes. This includes both BBP and Audits. A single accounting error yielded the largest individual payout ($50 k), but the headline for me is reentrancy: three…
I gave myself a challenge 1 month ago. Can I learn the Move Language and Aptos Framework from scratch and secure a Top 5 in this Move Competition all within a period of 15 days. Well I didn't disappoint myself. I secured the #2 Position with a payout of 26k USD. @cantinaxyz @aave

Dedicating the entirety of the month of July to Web3 BBP. Either I'll break or the contracts would.
Glad to secure the first place in Silo Finance Formal Verification contest. It was a great experience to both learn Formal Verification from scratch and secure the #1 spot in the period of 25 days. Hope to work on formal verification stuff in the future. @CertoraInc @cantinaxyz

This was a tough competition. In the end, I discovered 1 out of the only 2 medium vulnerabilities discovered in the contest and got #7/818 I learned a lot in this competition about the Liquity ecosystem. This was a really valuable contest to do. @cantinaxyz @LiquityProtocol
And they said the audit comp market is dead in may @cantinaxyz @_hrkrshnn
Writeup coming soon 👀
How auditing smart contracts has been like always. @cantinaxyz
For cantina, I created a script that fetches the current state of findings of a comp using API and automatically generates the leaderboard based on the prize pot provided. This is particularly useful when the leaderboard is not released. @cantinaxyz pastebin.com/VwDcJn7t
"Reentrancy doesn't happen in protocols anymore". Apparently I didn't get the memo. Got ranked 7/410 in @cantinaxyz Silo Finance competition with a solo medium reentrancy. Here is what reentrancy can help you achieve:
I encourage all SR to participate in the contest regardless of your skill level. Don't doubt your own capabilities. I have seen SRs scoring top 5 positions in their very first contest. #cantinaeigenlayer

Glad to be a part of the fellowship. Hope to begin this year to be an year full of learning.

The code review paid off and I was rewarded with the highest cantina bug bounty.

Spent the past month learning about Formal Verification and Certora Prover for a cantina contest. It may or not may prove to be fruitful in the short term in the contest. But I am definitely glad I learnt a new skill. We SRs always need to keep upgrading ourselves.
