Live Stellar Workshop | Week 5, Day 1: Building a Task Manager Smart Contract

Welcome to Week 5, Day 1 of the Live Stellar Workshop! As we continue our Soroban Crash Course, we are stepping up the complexity. Moving beyond the foundational Guest Book, today we are building a fully functional Task Manager Smart Contract. To engineer scalable blockchain solutions that drive real-world utility—especially for applications targeting the SADC region and the broader Web3 ecosystem—you need to master CRUD (Create, Read, Update, Delete) operations on-chain. In this session, we will design more complex data structures to represent tasks, manage state securely, and implement robust authorization to ensure users can only modify their own tasks. Course Resources & Links: GitHub Repository (Code & Notes): https://github.com/smwebsystems/sorob... Watch the Full Workshop Playlist: [Insert Playlist Link Here] What We Cover in This Session: Architecting the Task Manager: Designing Rust Structs to handle multiple data fields (Task ID, Description, Status, Owner). Advanced State Management: Storing and updating complex mappings on the Soroban ledger. Creating and Reading Tasks: Writing the core methods to initialize new tasks and fetch existing ones. Updating Task Status: Safely modifying blockchain state to mark tasks as complete. Securing Operations: Utilizing Soroban's require_auth to ensure only the task owner has permission to update or delete a task. Testing CRUD Operations: Writing local tests to verify all functionality before deployment.
