Learn to Build DeFi by Building DeFi
The Hack The Box of Web3. Free, gamified, hands-on protocol engineering and founder skills.
Two Tracks. One Mission.
Whether you write code or ship products, Zealynx Academy has your path.
Your Journey
From first line of code to production deployment. Every step builds on the last.
Read. Understand. Absorb.
Each section starts with concise, annotated theory. Real protocol code, not textbook examples. You'll read actual Uniswap, Aave, and Compound patterns broken down line by line.
Every concept backed by code from audited protocols.
Write Code. Pass Tests.
No copy-pasting. You write real Solidity in a browser editor, submit it, and automated tests verify your implementation. Build swap functions, lending pools, and governance systems from scratch.
Hands-on challenges with instant feedback.
Earn Lynx. Climb Ranks.
Every completed section earns Lynx. Every challenge earns more. Your rank climbs from Newcomer to Sovereign as you prove your skills. First to solve a new challenge? First Blood bonus.
7 ranks. Leaderboards. Badges. Your skill, quantified.
Ship With Confidence.
By the time you complete a path, you've built real protocol components, understood real vulnerabilities, and passed real assessments. You don't just know the theory. You've shipped the code.
Graduate ready to build production DeFi.
