I took Cyfrin courses 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.

Cyfrin has been an absolute game-changers in my journey into blockchain. Saying their resources were remarkable would be an understatement.
