Build. Audit. Launch.The Web3 & AI Builder Platform
Build real systems from scratch. DeFi protocols (Uniswap V2), AI security auditors, autonomous agents. Write every function, pass automated tests.
Prove it works in the Arenas. Shadow Arena: audit real protocol forks. AI Auditor Arena: benchmark your AI tools against real contests. Get scored. Compete.
Learn to launch with the Web3 eMBA. Tokenomics, fundraising, governance, go-to-market. Everything technical founders don’t know they need.
▎ Built by Zealynx Security, 41+ protocol audits. Free to start.
A real editor. Real tests. Real findings.
No videos. No slides. Three tabs that mirror how each Build module actually works — write code, run tests, compete in the Arena.
▎ Every Build module: write the functions, pass the tests, compete in the Arena.
Who is this for?
Three honest entry points. Each one leads somewhere we’ve already built and tested.
I want to break into auditing
Start in the Shadow Arena. Audit real protocol forks from past contests, get scored against real auditor findings.
Enter Shadow ArenaI’m launching a protocol
Build it from scratch so you understand every function. Then learn how to ship it as a business in the Web3 eMBA.
Build + launch pathI’m building AI security tools
Build an AI auditor with Claude Code skills. Benchmark it against real Code4rena contests in the AI Auditor Arena.
Build AI AuditorAfter 41+ audits, the gap was obvious.
You don’t watch. You build.
No videos. No slides. You write every function yourself. DeFi protocols, AI security tools, autonomous agents. Guided by starter code and automated tests.
Two arenas to prove your skills.
Shadow Arena: audit real protocol forks from past security contests. AI Auditor Arena: benchmark your AI tools against real Code4rena findings. Both scored. Both competitive.
AI meets security meets business.
Build protocols, then audit them. Build AI auditors, then benchmark them. Learn business fundamentals, then launch. Everything connects.
Built by auditors who saw the gap.
After 41+ protocol audits, we kept seeing builders fork code they don’t understand. So we built the platform. For builders, aspiring auditors, AI engineers, and founders.
Build → Audit → Launch.
Each surface works standalone. Start anywhere. The pieces connect once you’re ready.
Bite-sized cards. Real decisions.
Each lesson is a short stack of interactive cards — read a concept, swipe through judgments, vote, and answer. Around 8 cards per lesson. No watching, no skimming.
Designing emission schedules
What you will learn
- Why emissions are a cash-flow problem, not a code problem
- Three honest emission models (and when each breaks)
- How to defend an emission schedule to your investors
▎ Every eMBA lesson: tap through cards, make calls, see how other builders answered.
