I took Cyfrin course and I’ve been working as a solutions developer at OpenZeppelin for the last few months. It was by far the most comprehensive resource and the one that really teached me the fundamentals and made me want to switch from web2 to web3

The Cyfrin courses were a game-changer for me. They provided a well-structured and comprehensive introduction to web3 and blockchain development. The knowledge I gained allowed me to transition into a full-time role as a blockchain developer. I can't recommend these courses enough!

I took Cyfrin’s courses, and I took them seriously. At least one hour every day, documented the progress, didn’t skip any second. Haven’t found a better web3 course since. Now I’m full-time in web3, working as Senior Developer Advocate at Ceramic Network.
