Projects & Exercises

You will work on 3 projects which guide you through different facets of what it takes to create a sophisticated decentralised application, including a smart contract backend system and a full frontend.

In a first step you are going to learn how to transform a narrow-use smart contract into a global utility, how to protect your users and how to protect your smart contract from your users.

The second project demonstrates, by trial and error, how the public nature of Ethereum, gas price and mining delays cannot be ignored when coding in Solidity. Further, you will learn the art of balancing interactions and actions between client-side and chain-side.

The third project is a well-known child's game that, although disarmingly simple, requires careful considerations when played on Ethereum. You will reapply teachings learned in the previous projects while ensuring you do not ruin your players' finances.

Hands-on teaching

You have full-time access to our team of instructors. When you hit a snag or have a question, you can just message them. You also join a wide community of students, who exchange experiences and learn from each other.
