About Zealynx Academy
We are protocol auditors who got tired of seeing builders fork code they don't understand. So we built a platform where you learn by building the real thing from scratch.
Built by Zealynx Security
Zealynx Academy is created by Zealynx Security, a boutique smart contract audit firm based in Wroclaw, Poland. We have completed 30+ protocol audits for clients including Fair Labs, Novaswap, Golden Grid, Inverter, Mangrove, and more.
Every lesson, test, and security pattern in the Academy comes from real audit experience. When we say "this is how a reentrancy guard should be implemented," it is because we have seen what happens when it is not.

To Start
Founded by Carlos Vendrell
Carlos Vendrell is the founder and lead auditor at Zealynx Security. He has personally reviewed 30+ DeFi protocols across AMMs, lending pools, vaults, bridges, and governance systems. He created Zealynx Academy because he saw the same problem over and over: builders forking protocols without understanding what they were forking.
The Academy is his answer: a platform where you build production protocols from scratch, function by function, so you truly understand the code before you build on top of it. Then you audit a real fork to develop security intuition. Then you learn the business side with the eMBA for Web3 Founders.
Why We Built This
During our audits, we kept seeing the same pattern: teams would fork Uniswap V2 or Compound, modify a few functions, and deploy. When we flagged vulnerabilities, they often did not understand the original code well enough to evaluate our findings. They had forked without understanding.
We realized there was no platform that made you build the protocol instead of copying it. Tutorials teach you theory. Bootcamps teach you syntax. But nobody makes you write the swap() function, the mint() function, the fee calculation, from scratch, guided, until you pass all 207 tests.
That is what Zealynx Academy does. And after you build it, we let you audit a real fork of it in the Shadow Arena. And then we teach you how to launch the business around it with the eMBA.
