[SOLUTION] Please describe your proposed solution

Solution Summary

We propose to develop a Cardano wallet connector for Unreal Engine that will enable developers to integrate Cardano blockchain assets directly into their games. This connector will allow games to read the contents of a user’s Cardano wallet and use this information to control access to game levels, unlock special items, and enable other blockchain-related interactions. The project will focus on delivering the core functionalities of the wallet connector and providing comprehensive documentation to assist developers in integrating it into their projects.

Solution Overview

The proposed Cardano wallet connector will include the following key features:

Wallet Authentication:

• Secure connection to the Cardano blockchain via compatible wallets.
• User authentication through wallet signature verification.

Asset Retrieval:

• Ability to retrieve and verify assets (e.g., NFTs) from a connected Cardano wallet.
• Filtering of assets based on policy ID or other parameters.

Game Integration:

• API for Unreal Engine to interact with wallet data, enabling developers to use blockchain assets for gameplay features.
• Examples include unlocking game levels based on ownership of specific NFTs, controlling item availability, and customizing characters or environments.

Blueprint Visual Scripting:

• Custom nodes and functions for Unreal Engine’s Blueprint Visual Scripting, allowing developers to implement wallet interactions easily without advanced coding skills.

Documentation and Examples:

• Comprehensive documentation to guide developers through integrating the wallet connector into their projects.
• Example project to demonstrate the connector’s functionality in a simplified game environment. This will showcase the wallet connector's potential but are not intended as fully polished games.

Our team has extensive experience in blockchain development, 3D design and game engine integration, particularly with Unreal Engine. We have successfully delivered similar projects and possess the technical expertise to integrate Cardano’s blockchain with game engines. We will implement a phased development approach with regular milestones to validate feasibility. Each phase will be accompanied by thorough testing and community feedback to ensure the connector meets developers' needs. Open-source development practices will be employed to ensure transparency and community involvement.

[PROJECT MILESTONES] What are the key milestones you need to achieve in order to complete your project successfully?

In this initial phase, we will focus on laying the groundwork for the project. This involves comprehensive research into the technical requirements, defining user needs, and identifying the appropriate design principles for the Cardano wallet connector. During this phase, wireframes will be created to visualize how the connector will interact with Unreal Engine, while technical specifications will outline the system's functionality. This stage ensures all stakeholders are aligned before development begins.

• Output: Detailed project plan, technical specifications, and initial design documents.
• Acceptance Criteria: Key stakeholders approve the project plan and technical specifications.
• Evidence: Project documentation and wireframes.

During this phase, we will implement the wallet authentication functionality, enabling secure connections between the Cardano blockchain and Unreal Engine. This milestone focuses on developing the core wallet integration, allowing the game to connect to the user’s wallet, verify ownership, and retrieve basic assets like NFTs. This will serve as the foundation for the connector's future functionalities.

• Output: Development of wallet authentication and basic asset retrieval functionality.
• Acceptance Criteria: Successful connection to a Cardano wallet and retrieval of assets.
• Evidence: Working prototype demonstrating wallet connection and asset retrieval.

Building on the basic integration, this phase will introduce advanced asset filtering, such as the ability to filter assets by policy ID and other parameters. The development of an API for game integration will also occur during this milestone, allowing Unreal Engine games to use blockchain assets (e.g., NFTs) to influence gameplay, such as unlocking content, modifying in-game characters, or offering item customization.

• Output: Advanced asset filtering and Unreal Engine API development for game integration.
• Acceptance Criteria: Ability to filter assets by policy ID and use them to influence game state.
• Evidence: Demonstration of filtered asset retrieval and API interaction within an Unreal Engine project.

This phase focuses on creating comprehensive documentation that allows developers to easily integrate the Cardano wallet connector into their Unreal Engine projects. We will also develop example projects that showcase the connector’s core functionality, including wallet authentication, asset retrieval, and integration into basic gameplay scenarios. These example projects will serve as a guide for developers looking to implement similar features in their own games.

• Output: Comprehensive documentation and example project to assist developers.
• Acceptance Criteria: Documentation and example projects are complete and available for use.
• Evidence: Published documentation and Unreal Engine example projects demonstrating connector use.

In this final phase, we will focus on thoroughly testing and optimizing the Cardano wallet connector to ensure it is stable, secure, and high-performing. Rigorous testing will be conducted to identify and resolve any bugs, improve performance, and ensure the connector operates seamlessly in different environments. After incorporating feedback and making the necessary adjustments, the connector will be deployed on the Cardano mainnet for use by the broader developer community.

Following deployment, we will compile a comprehensive project close-out report, summarizing the development process, key achievements, and lessons learned. Additionally, we will produce a video walkthrough showcasing the connector’s core features, including wallet authentication, asset retrieval, and integration with Unreal Engine. These materials will serve as both internal reviews and promotional content for stakeholders.

• Output: Final testing, optimization, deployment of the wallet connector, project close-out report, and video walkthrough.
• Acceptance Criteria: Stable, fully functional wallet connector ready for public release; stakeholders approve the project report and video walkthrough.
• Evidence: Test reports, user feedback, final deployment to the Cardano mainnet, completed project report, video demonstration, and stakeholder sign-off.
