Hello Roberto, I’m so glad to see you here! Let me start by saying that I wish I could have space for all the applicants, especially for people like you who are willing to come here and take the materials and study by themselves as you are doing right now! I want to personally congratulate you on your initiative!
The material will be published here tomorrow!
It will be published in batches. Today, we have the 3rd session to finish the first module, and we will share the presentation and the assignments that we have made so far! then i will share here the 2cn module and so on. Please feel free to post here any questions that you may have when going through the content!
Next month we will have another OPDAY for everyone who wants to participate and you are more than welcome to attend, learn and share with us on the superchain!
Congratulations to all the dedicated participants who are part of this movement. In this post, we aim to recap everything covered in these initial three sessions of the course. This serves both as a review and as a resource for anyone looking to learn about these topics.
In our first session, we covered the following topics:
In the practical part of this session, each student created their wallet and opened it in two different applications: Metamask and Rabby Wallet. They learned to securely import and store their private keys and minted their first attendance NFT using Hallos.io. This allowed them to record their attendance on-chain, and they used a block explorer to identify this transfer.
Homework: Investigate the differences between Proof of Work and Proof of Stake.
After this session, each student was sent gas in the Sepolia, OPSepolia, and Optimism mainnet networks.
Our second session focused on equipping students with the tools and knowledge needed to excel as Web3 developers. We had a special guest, Daniel Bejarano, a developer with practical experience, who shared his journey to becoming a successful Web3 developer. Topics included:
We also covered the functionality of test networks and faucets. Daniel shared his personal experiences and results, empowering students and highlighting the potential of the Web3 path. He also provided several tips on creating developer networks and accounts.
Homework: Create and optimize profiles on social platforms like GitHub, Twitter, LinkedIn, Telegram, and Discord.
In the last 15 minutes, we conducted a speed networking activity to foster student interaction. Students received their first reward of 10 OP tokens and manually added the token using the OP contract.
In the third session of this module, we delved into Ethereum, the EVM, and its technological use cases. We provided in-depth knowledge about gas on the network, conducted interactions, and discussed Layer 1 compatibility with Ethereum. Topics included:
We had another special guest, Robert Ramirez, founder of Hallos, who shared his experience as a Web3 startup founder.
In the practical part, students created a Gitcoin Passport to establish their on-chain identity and verify it, thus proving their uniqueness and backing their work with on-chain evidence. They used the Sepolia faucet, benefiting from having an active Gitcoin Passport.
Upon completing this session, we’ve achieved a perfect success rate in assisting all students. As recognition of their accomplishment, students who hold all assistance nfts got whitelisted and can claim a Module 1 completion POAP.
Homework: Achieve more than 10 points on their Gitcoin Passport and explore the CryptoZombies platform to start learning Solidity in preparation for the Solidity module.
Here are the presentations from these initial sessions for your reference. Feel free to leave any questions in the comments—we are here to support you on your journey as developers on the Superchain!

Thank you for sharing the summaries and the presentation! It has been an intensive course, and challenging, but so enriching and motivating to learn this great technology. Let’s seek for more and deep understanding!
really excited about that!
Thank you so much @inbestprogram.eth for sharing this awesome summary.
It has been an inspiring experience from the theorical and practical perspective as I have been able to understand the basic aspects of a blockchain that would allow us to also be conscious and recognize how to optimize from the user and technology perspective when developing. Also having the second session focused on personal branding made me realize all the points that I can improve to start positioning myself and create valuable networking.
Thank you Optimism and Cenfotec for making this possible.
