Audit training that feels like the work

Learn the workflow, not just the bugs.

Move from reading Solidity to building PoCs, proving impact, writing findings, and using AI as backup instead of a crutch.

319 Audit Lessons A guided path through EVM behavior, DeFi failure modes, and the review habits that catch real bugs.
50+ Exploit Labs Hands-on contracts where you trace value flow, trigger the bug, and turn the result into a useful finding.
SSCH Proof Of Skill A QR-verifiable, score-backed credential that shows how you performed on practical security work.
Who This Course Fits

For builders ready to audit smart contracts.

You can read Solidity. Now practice finding bugs, proving impact, and writing findings.

Developer path

Solidity developers

  • Read unfamiliar contracts
  • Map value flow
  • Build an audit routine
Contest path

Bug bounty hunters

  • Write cleaner PoCs
  • Reason about severity
  • Submit sharper findings
Security path

Security engineers

  • Learn EVM risks
  • Review DeFi flows
  • Validate findings
Prerequisites: Solidity basics and comfort reading code. Still early? Start with SCH Lite
What You Practice

Practice the smart contract audit workflow.

Model the protocol. Find the path. Prove impact. Write it clearly.

01

Model the protocol

  • Trace value flow
  • Map trust boundaries
  • Spot risky assumptions
03

Prove impact

  • Build the PoC
  • Check severity
  • Reproduce the issue
Final habit Move from code reading to defensible audit judgment.

Frequently Asked Questions

Questions before you join?

Here are the answers most people need before enrolling.

This course is for Solidity developers, bug bounty hunters, and security researchers who want to audit real contracts.

You need basic JavaScript and Solidity foundations. If you are still early, start with SCH Lite or CryptoZombies, then move into the full auditing track.

It is a smart contract auditor course. You practice reading contracts, writing exploits, proving impact, and reporting findings.

You will cover EVM internals, attack classes like reentrancy and flash loans, exploit writing, report writing, and AI-assisted auditing.

Yes. You learn to prove findings, explain impact, assign severity, and write issues teams can act on.

Yes. Full enrollment includes the SSCH certificate, a QR-verifiable credential with assessment score details.

That is the point. The course helps you find better issues, prove them, and write them clearly.

AI is treated as a helper, not the auditor. You learn how to use it while still checking the work yourself.
