Last month, I reported a critical severity vulnerability in a Cosmos SDK-based blockchain project and was awarded a $20,000 bounty. Thanks to @WhiteHatMage for the advice on handling communications in private bug bounties.

There’s a lot to say, but in the interest of keeping this criticism constructive, I won’t go over every single point. By posting this tweet, you’re damaging your own marketing, because any reasonable SR or project founder might stop taking you seriously after seeing it, and.
A lot of people probably wonder what my company, Pantheon Labs, actually is and what the goal is. Basically, in a couple months, once I build more of a name in the cybersecurity space, we’ll be offering full audits to blockchain companies directly. Each audit will guarantee that.

My notes are full of quirks I've come across in codebases and attack vectors that currently have no impact but could become critical as conditions evolve. I've seen this happen more often in Blockchain/DLT programs, but it applies to smart contracts as well, especially with the.

I second this. Projects that don't accept (reward) low severity reports usually don't take security seriously enough.
@storming0x @WhiteHatMage The best bounties don’t just have “Critical” only programs with a ton of restrictions. Security gets better with every valid report and our projects get this. What’s low today could be critical tomorrow.

Where I'm at currently:. My goal remains the same, I haven’t given up. However, there’s been a small hiccup: Like most of you, I tend to hunt based on projects I'm interested in rather than picking from platforms. Unfortunately, only one of them is currently listed on Immunefi.

We need more Cosmos-SDK blockchains on @immunefi. It’s a huge ecosystem, but only few projects have a BBP. Also, private BBPs drive away most white hats.
