One morning in April 2022, my life changed.

Over a warm latte, I heard an exciting story from a friend. He spoke of someone earning a jaw-dropping $2,000 an hour.

I needed a new challenge, and this was my ticket out of boredom.

I spent hours reviewing Christoph Michel’s blog and Code4rena’s documentation that day.

“It started very high at 2,000$/h, and I stayed above 1,000$/h for most of 2021 until the big drop in November 2021. Afterwards, I was and still am averaging 500$/h.” — Christoph Michel

The Birth

Soon after, I started learning Solidity. With Patrick’s helpful YouTube videos as my guide, I took my first steps as a smart contract auditor. It wasn’t an easy road. As a beginner, finding good learning materials and guides was tricky. I participated in many contests, and although I understood the code, finding bugs was a real struggle.

This struggle led to a great discovery. Reading past reports from contests was a quick and effective way to improve. But there was a problem — I couldn’t search for these past reports. That’s when I had an idea for a new tool — Solodit.

In October 2022, I set out to create Solodit, a tool to search for past reports from Code4rena and Sherlock. Thanks to my development experience, I built a basic version of Solodit in just 2–3 weeks.

Using Solodit was a game changer. Every day, I spent hours studying old reports and building up my skills. The hard work paid off. I started performing better in contests, and within a few months, I was #1 on the 90-day leaderboard (still holding the top spot in 2023!).

Rank #1 in 2023 as of 15th July, 2023

Realizing that Solodit could help many others like me, I decided to make it public earlier this year. The response was amazing. Solodit quickly became a platform used by thousands of auditors.

Solodit Today

Solodit aggregated a lot of reports from major audit firms and top auditors.

Today, Solodit is more than just a tool. We aim to be the go-to place for everyone involved in web3 security. We want to offer reports, news, learning materials, and tools for web3 security auditors — all in one place.

My journey from that April morning in 2022 to leading Solodit has been unique and rewarding. But this is just the beginning.

We at Cyfrin are working on a free, end-to-end roadmap for developers, smart contract auditors, and the Web3/Crypto curious. You can start by learning Solidity and security audits with Patrick’s YouTube videos, sharpen your skills using Solodit, and even earn while contributing to Web3 security at CodeHawks.

smart contract audit marketplace — codehawks
CodeHawks covers all audit projects, from bid-based solo audits to public contests.

There’s an old saying, “If you want to go fast, go alone. If you want to go far, go together.” We can go far with Solodit, making Web3 safer for everyone.

In my next blog post, I’ll share my journey to the top of the C4 leaderboard, largely thanks to Solodit.

Stay tuned!
