For the workshop, we will explore the real-life protocol called “Stonks,” created and deployed by Lido. In the beginning, we will learn the code architecture and understand all the important parts required to create a fuzz test. Next, we will go through a pre-made implementation of a fuzz test written using the Foundry framework. In this example, we will show the difficulties that a developer may encounter while writing tests in Solidity. Next, we will interactively recreate the same fuzz test in Python using the Wake framework. We will show how fuzzing helped Ackee Blockchain find the actual bug in the Stonks code, which we will fix. Finally, we will compare Foundry and Wake and show the advantages and disadvantages of both approaches.

We expect attendees to have a basic knowledge of Solidity. Knowledge of Foundry and Wake is not required, as we will provide full guidance on the code.
