Beerfi Prague - Web3 on-chain dev Meetup #25


Once a month on the last Tuesday, we bring together contract programmers in Web3. Whether you are a Web2 developer interested to learn more or a senior in the Web3 sphere, our meetup is for you!

Enjoy a nice cold lager and get ready to blow your mind on what’s possible in blockchain.

Make sure to check out our sponsor, AgorApp!

AgorApp provides an interactive coding environment to learn Web3 programming on different chains & protocols. Right now you can take courses & challenges to learn Solidity (Ethereum), Motoko (Internet Computer) Ethereum Swarm, NEAR & Lisk with more coming! You can check it out at:

Last meetup we focused on ZK witchcraft, Certora R&D and Ethereum scaling and blobscriptions.

Our upcoming meetup will be again hosted at Decada - a crypto-friendly cafe bar with an inviting atmosphere and friendly staff. Decada's commitment to innovation makes it the perfect venue for gathering like-minded developers. They are happy to invite us to join them for an evening of fresh perspectives, vibrant discussions, and good company at Decada.
