The Sovereign SDK is a free and open-source toolkit designed for creating rollups (both ZK and optimistic). It’s great for developers wanting to build secure and efficient applications. In this guide, we will explore the essential components of the Sovereign SDK and show you how to get started with building your own rollup.

Understanding the Sovereign SDK’s Structure

Picture the Sovereign SDK as a toolbox designed for crafting custom solutions in a new neighborhood of applications. Think of three main tools within this toolbox:

• The Rollup Interface: Acts as the blueprint that all custom homes (rollups) must follow to ensure they can stand upright and connect to utilities.
• The Module System: This is like a collection of modules (furniture) you can use to fill your home as you see fit, whether it’s a sectional sofa for comfort or a sleek dining table for functionality.
• The Full Node: Consider this the construction crew that helps raise and maintain your custom home, ensuring everything runs smoothly.

Components Breakdown

The Rollup Interface

The Rollup Interface is where the magic begins. It consists of three critical components:

• State Transition Function (STF): Defines what happens to the data in your application—the business logic.
• Data Availability Layer (DA Layer): This layer is responsible for fetching the transactions that will be processed to change the state.
• Zero Knowledge VM (zkVM): It’s like your home inspector, providing secured proof that everything is in order with the logic implemented in your rollup.

The Module System

The Module System allows for flexibility in how your STF is constructed. Just as you can mix and match furniture styles, you can also assemble different modules to create your perfect application. It provides core traits and functionalities that can fit together, making it easy to build complex applications without hassle.

The Full Node

This component functions like the management team ensuring everything in your neighborhood runs smoothly. It helps you deploy your rollup and manages data, RPC requests, and interactions ensuring everything is synchronized properly.

Troubleshooting Common Issues

While embarking on your development journey, you might encounter some bumps along the way. Here are a few troubleshooting tips:

• If the Full Node doesn’t connect as expected, ensure that all dependencies are correctly installed and configured.
• Missing modules? Double-check your references and imports in the code to ensure everything is in place.
• Unexpected errors while running rollups? Look closely at the logs for any clues on what went wrong.
