A hands-on course to hack and audit smart contracts. Learn EVM fundamentals, real exploit practice,
and AI-assisted audit workflows, all within a proven framework.
One focused program that turns you into a paid smart contract auditor, with the skills and the credentials to prove it.
The fair question before any course is what you actually get for the money. These are the three capabilities that the program delivers that separate a paid auditor from a developer who just reads Solidity.
You'll master every major attack class, so you can navigate, critically analyze, and deconstruct any contract, instead of just matching it to bugs you've seen before.
From instructors, who are some of the best auditors in the field, to hiring managers and fellow students who later become colleagues, contest partners and audit buddies.
A score-backed certification that shows exactly how much you know. It's the credential hiring firms and contest organizers actually take seriously.
Top auditors protect billions in on-chain value, and they get paid to find the bugs that would've cost fortunes.
Few security specializations pay this well, this young in your career.
Each certificate includes QR verification for fast authenticity checks.
Shows your final evaluation score to provide clearer signal on skill level.
Adds objective proof of training when applying to teams and clients.

“We have a super healthy and helpful Discord community where people help each other not only discussing the course's exercise but with other relevant doubts. Also, the amount of work JohnnyTime put into this course is visible in the repository where he made sure all the setup is ready…”
“I've just finished the @RealJohnnyTime course about Solidity Security and honestly, I wasn't expecting that much. I would say the value of this course is huge.”
“The best money I've spent in a while was definitely on @RealJohnnyTime smart contract hacking course.”
“Transitioning into Web3 Security by @0xOwenThurm is my favorite section. Best decision this year.”
“This course is an amazing kickstart for your smart contract security researcher career. Thanks Johnny for creating it!”
“Learning from web3 security experts has been incredible. The registration was smooth and Johnny's guidance has been very responsive.”

A short walkthrough of how the training is structured, what you will practice, and what the full program is designed to help you do.
Straight answers on prerequisites, AI, pacing, payments, and whether this program fits your current level.
Great question. This is an intensive, practical course designed to build professional smart contract security skills.
The course consists of 2 parts for the most comprehensive learning experience:
Part 1: 119 videos, 13 hours of learning, and 20 exercises.
Part 2: 200 videos, 20 hours of learning, and 30 exercises.
You also get advanced guest lectures from top professionals on career growth, getting hired by audit firms, and building a private audit practice.
These are some of the chapters that will be covered in the course:
You should have basic knowledge of:
I would suggest learning solidity in a fun way for free by going through a short and interactive CryptoZombies course.
Finally, I recommend reviewing the Bitcoin and Ethereum whitepapers so you can start with stronger context.
Yes. You can pay through Stripe and PayPal.
Yes. We run a private Discord community exclusively for students so you can get support while moving through the course.
You can ask questions, discuss exercises, connect with peers, and interact with the SCH team.
Yes. All lectures and exercises are pre-recorded, so you can move through the material at your own pace. We also run live Q&A sessions to answer questions and help you connect with other professionals.
There will be more information about the live sessions coming up in announcements, so make sure to stay tuned on social media:
Completion time depends on your pace and daily schedule. Most students can finish the full curriculum in about 3 months.
If you can study 4-5 hours per workday, you may finish in about a month.
If you prefer a steadier pace at 2-3 hours per day, completion is usually around 1.5-2 months.
The course supports a wide range of skill levels and helps students deepen practical smart contract security knowledge.
It starts with strong fundamentals and also covers advanced topics like flash loans, oracle manipulation, and DAO/governance attacks.
By completing the course, you'll be able to find vulnerabilities, write proof-of-concepts, and apply an attacker's mindset in real assessments. These skills are directly useful in contests and bug bounty programs.
Deep understanding of the course material can substantially improve your readiness for junior smart contract auditor roles. We do not guarantee employment, but the training is built to strengthen real hiring-relevant skills.
It's a fair question - and the answer is nuanced. AI tools are genuinely powerful and will find pattern-matching bugs. But they also hallucinate fixes, miss economic and game-theoretic vulnerabilities, and can't understand protocol context without expert guidance.
The principle is simple: garbage in, garbage out. If you don't understand reentrancy, oracle manipulation, or flash loan mechanics deeply, you can't evaluate whether the AI's output is correct, missed something critical, or created a false sense of security.
The most effective auditors are not replacing expertise with AI - they are directing it. Deep fundamentals turn AI into a reliable force multiplier.
The course is intentionally built around the fundamentals that make AI tools effective. When you deeply understand EVM internals, attack vectors, and DeFi mechanics, you gain the ability to:
Understanding the fundamentals at depth is exactly what makes AI actually useful - rather than a tool that generates plausible-sounding but dangerous output.
Yes. Cairo and Starknet have a different security model from Solidity, so they deserve dedicated study. Start with the Cairo smart contract security guide to understand the audit surface, then use the Cairo Smart Contract Hacking Course when you want hands-on Cairo labs.
Yes. AI has changed the market, but that increases the value of auditors who can validate findings and reason about protocol risk.
What's happening right now:
The auditors who will be most valuable in 2028 and beyond are those building their fundamentals today.
