What you'll learn

Learning how to build Dapps on Ethereum is overwhelming and frustrating. The architecture, tooling, and even the programming language is different from traditional Web 2.0 development. It requires unlearning all the traditional web development concepts and relearning blockchain development concepts from ground up, which can be daunting when you are doing it alone.

Moreover, learning how to build a Web 3.0 application that is secure from malicious hackers adds a whole new element of complexity that developers have to reason about.

In this course, you get hands-on experience on how to architect, develop, and scale a Web 3.0 app on Ethereum. You will have the opportunity to collaborate with like-minded peers to learn and build together. You will also meet with world-class founders who built some of the most successful apps on Ethereum to understand best practices and common pitfalls.

You walk away with a production-ready application that you can showcase in your Github portfolio or turn a startup. Best of all, you will have a cohort of potential co-founders and lifelong friendships.

After this course, you will have the skills and network to launch your career as blockchain developer or founder.

Preethi Kasireddy

Preethi started her crypto career as a software engineer at Coinbase and helped launch Ethereum onto the Coinbase platform.

She then taught herself Ethereum Dapp development during the 2017 ICO boom and built smart contracts for various crypto projects before deciding to start her own crypto company called TruStory. At TruStory, she and her team built their own blockchain on Cosmos.

Before Coinbase and TruStory, Preethi was a partner at Andreessen Horowitz where she worked on deals such as Buzzfeed, Stackoverflow, Envoy, SmartCar and others. Prior to that, she was an Investment Banking Analyst at Goldman Sachs.

Her well-rounded experience as a founder, engineer, investor, and banker gives her a unique lens into the world of crypto and finance. She has a knack for teaching– many of her courses and blogs have gone viral.

What you'll learn

Why choose this course over a MOOC?

Active Learning, not Passive Watching

Workshops aren't monotonous lectures. Every workshop will be highly engaging, with breakout discussions, group activities, polls, brainstorming, and Q&A. Think interactive video game vs a passive YouTube video

Learn with a Cohort of Peers

You will walk away with friends and potential cofounders who you can build the future with. Think hackathon, but extended over a period of 3 weeks so that you can building something meaningful instead of “hacky”

Accountability and Feedback

The biggest benefit of a cohort-based course is accountability and peer support. By building in a group setting, you will constantly be surrounded by constructive feedback and motivational energy. Moreover, Preethi and the coaches will be highly engaged in giving every student 1:1 feedback through the course.

Preethi is the rare combination of a great engineer and great teacher/communicator. She is patient, articulate, and kind, breaking down complex topics into bite size pieces to accelerate your learning.

CEO of Coinbase

Preethi is a gifted teacher. She truly understands how to break down complex technical concepts. I recommend any developer interested in blockchain development to take her course.

Managing partner at Dragonfly Capital

I've recommended Preethi's crypto course to many of my own friends and network. She does a great job synthesizing information and making you feel confident that you actually can tackle this stuff.

Learn with a comprehensive curriculum

  • 1

    Pre-readings and homework

    We will expect you to learn the basics on your own so that we can spend class time covering intermediate and advanced topics. You will be given homework and readings to complete before the first day of class, which are designed to give you a basic understanding of Ethereum, Solidity, and Dapp development.

  • 2

    Meet & Greet

    It’s like the first day of school! This is when you will meet with your fellow DappCampers who will be your ride or die for the next 3 weeks. We will also review the curriculum, set expectations, and send you home with a little homework ;)

  • 3

    Solidity deep dive

    Solidity is the programming language used to build smart contracts on Ethereum. The prerequisites for the bootcamp will require you to learn the basics of Solidity. In this module, you will learn and practice intermediate and advanced concepts. You will then use your newfound Solidity skills to build an ERC20, ERC721, and ERC 1155 token contract from scratch! Don’t worry, this is a group exercise and will get you warmed up to start building on your own. Finally, you will be given all the necessary information for your final project. By the end of this module, you will have formed your teams and finalized your Dapp idea.

    Build a Gaming Dapp (Part 1)

    In this module, you will begin building a complex gaming Dapp from scratch in a live setting with your fellow DappCampers. You will first learn how to architect a Dapp and how the architecture differs from Web 2.0 applications. Then you will start building right away. Prepared to be challenged and enlightened. After building the basic structure of your first Dapp together, you will learn how the Ethereum tool chain works, including various developer frameworks, testing frameworks, auditing services, decentralized storage solutions, oracles, and more.

  • 5

    Build a Gaming Dapp (Part 2)

    You will continue to build more functionality onto your Gaming Dapp from the previous lecture. This is where we get into the weeds and build some complex functionality. Once the core functionality is built, you will learn how to write tests for your smart contracts. Finally, you will officially deploy your Dapp onto the Ethereum testnet and make it live for the world to see!

  • 6

    Security analysis

    Learning how to build and scale a Dapp is not enough. As a Solidity developer, you will be expected to learn how to build smart contracts that are secure against adversarial attacks. In this part of the course, you will gain a deeper understanding of the common vulnerabilities in Solidity and how to defend against them. You will be asked to “break” a DeFi app and drain all of the money out of it. Finally, there will be a fun challenge for you to complete at home where you are asked to discover various vulnerabilities in smart contracts.

  • 7

    Advanced Web 3.0

    By now, you have a very solid technical understanding of the Ethereum blockchain and how to write secure and scalable smart contracts. In this final lecture, we will cover some advanced concepts such as deploying your application onto Polygon, Arbitrum, and Starkware, how to write upgradeable smart contracts, and more.

  • 8

    Demo day

    By this point in the course, you’ve spent 3 weeks learning and building. Now, it is time to showcase what you’ve been building all along! You and your team will have 10 minutes to present your final project to your cohort mates and a few special guests. Think of it as YC demo day where you have the opportunity to show off what you’ve built and maybe even recruit a team and investors around you :)

  • 9

    Special Guest Lectures

    There will be a series of guest lecturers throughout the course. Previous guest lecturers include Balaji Srinivasan, Nader Dabit (Edge and Node), Coopahtroopa (FWB), Mudit Gupta (Blockchain security researcher at SushiSwap), Haseeb Qureshi (Dragonfly Capital), Jesse Walden (Founder of Variant Fund), Zahoor Mohamed (ETH 2.0 contributor), and founders of various crypto projects. The guests will share lessons learned in their career in crypto and best practices for building on Ethereum. You will have an opportunity to ask them all of your burning questions! Students will also have access to recordings of all past guest lecturers!
