What our learners are saying

Starting internship next month at Swiss Re5. Coolest stuff tbh! Wrote my first solidity code with the help of Metaschool's well-explained course, fun part is they give out NFTs when you complete a course. So, win-win always.

Metaschool's courss are the most detailed and practical oriented. It helped me alot as I have created more that five ERC 20 tokens for different clients.
