Syllabus

Unit 1 - Game Overview & Quick Experience

In this unit, we will learn the core concepts of CrossGuess cross-chain prediction game, experience the actual gameplay flow based on Wormhole Settlement technology, and gain deep understanding of why Settlement makes cross-chain gaming possible.

Unit 2 - Project Setup & Environment Configuration

In this unit, we will transition from concepts to practice by hands-on building the complete project development environment. You will learn how to configure multi-chain wallets, install project dependencies, set up environment variables, and successfully run the game.

Unit 3 - Code Architecture & Wormhole Integration

In this unit, we'll dive deep into the project's complete code architecture and component relationships, and master the proper integration and configuration methods for the Wormhole SDK.

Unit 4 - Game Customization and Parameter Adjustment

By completing this unit, you will be able to flexibly adjust the blockchain parameters of the CrossGuess game to suit different requirements, master techniques for multi-chain switching and token pair configuration, learn to optimize game duration and round settings, and integrate new settlement routes to expand game functionality.

Unit 5 - Optimizing Project Practices

This unit will guide you through best practices for Wormhole Settlement in production environments, including ensuring game fairness, transaction monitoring, error handling, and deployment strategies.
