If there’s one resource that Web3 developers point to, it’s Cyfrin’s ultimate tutorials. They’re standout resources that have empowered countless developers to learn blockchains, learn Solidity, and dive deep into Web3 development.

Gustavo Gonzalez

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.

Francesco Andreoli

Cyfrin Updraft videos on smart contract development have been instrumental in my blockchain journey, standing out with their clarity and accessibility. Their readiness to support and engage with learners makes me excited for more of their interactive and insightful content in the Web3 space

Albert Hu

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!

Radek

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.

Boidushya

Cyfrin have been an absolute game-changers in my journey into blockchain. Saying their courses were remarkable, would be an understatement. Thanks to their expert guidance, I gained a deep understanding of blockchain to its roots. I'm forever grateful for their role in helping me get started in web3.
