    We can build systems for Ethereum scaling but without education, it’s all for nothing. Updraft is the first step towards adoption for Web3 education. We can now mint security focused developers at scale!

    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

    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.
