[Campaign Category] Category Questions

Describe what makes your idea innovative compared to what has been previously funded (whether by you or others).

Problem:

Existing solutions require complex backend infrastructure, web-based workarounds, or deep blockchain expertise that disrupts development timelines or breaks immersive gameplay experiences.

Our Solution:

An easy-to-install Unreal Engine plugin that supports multiple Cardano blockchain providers, which can create and restore wallets without provider dependency. This plugin will provide multiple drag-and-drop blueprint functionality for wallet features

Describe what your prototype or MVP will demonstrate, and where it can be accessed.

Our prototype currently achieves the ability to create and restore wallets on macOS, iOS, tvOS, Android, and Windows platforms. It can be accessed for beta testing in this GitHub repository: https://github.com/McManford/UnrealCardanoPlugin

It can create lovelace and multi-asset transactions using the Blockfrost API; the goal would be to extend that capability to the other providers and transactions for NFT-related assets.

Describe realistic measures of success, ideally with on-chain metrics.

See an increase in wallet activity and users in the Cardano space. Success would be seeing an increase in Cardano-based games in the GameFi space. Currently, the numbers are relatively low for the plugin download, but we are seeing daily and weekly activity for this plugin.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

An Unix-like approach; Unreal Engine plugin providing Blueprint-accessible Cardano functionality through the libcardano-c library. Developers can generate/restore wallets, send ADA/tokens, query balances, and manage multi-assets directly within games using visual scripting. Months of blockchain integration turn into simple drag-and-drop Blueprint nodes, enabling true Web3 gaming experiences on Cardano. Giving the options of using Koios, Ogmios, Blockfrost, or other API providers/tools to handle wallet activity.

[Your Project and Solution] Impact

Please define the positive impact your project will have on the wider Cardano community

In its prototype phase, it is already bringing a positive impact to the community. This project gives more exposure to the gaming space, enabling developers and content creators to leverage Cardano's technology and features.

Here are some online articles that recognize this plugin:

[Your Project and Solution] Capabilities & Feasibility

What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

• Proven Technology: Built on libcardano-c, ensuring security and compatibility on various platforms. Working prototype successfully tested on multiple platforms: Windows, macOS, iOS, tvOS, and Android
• Demonstrated Features: On-device wallet generation/restoration, multi-asset transactions, balance queries via Koios, Ogmios, and Blockfrost APIs. Currently available for public testing.
• Development Expertise: Deep experience in software development. Clear roadmap with achievable milestones, including fee estimation and token selection.
• Community Validation: Public GitHub repository, active testing community, and proven technical feasibility.

[Milestones] Project Milestones

Milestone Title

Plugin Foundation & Documentation

Milestone Outputs

• Invest in proper licenses and equipment for supporting cross-platform (e.g., hosting VMs on cloud services)
• Updated libraries supporting Windows, Mac, Linux, Android, iOS, and tvOS
• Clean class structures, to make it coherent and organized for the user
• Add missing blueprint functions for each API service (Ogmios, Koios, Blockfrost, etc.)
• Add other services if needed (NMKR service provider)
• Include documentation and tutorial videos in GitHub
• Test out each service's basic wallet operations (transaction creation, restore wallet, balance queries, etc.)

Note: Personal funds were invested during the R&D phase to address cross-platform compatibility challenges and establish the technical foundation for multi-platform support.

Acceptance Criteria

From prototype to production, the plugin is released with comprehensive multi-provider support and professional documentation.

Technical Requirements:

• All Blueprint functions refactored with clean, organized class structures
• Complete API coverage for Blockfrost, Koios, and other Cardano service providers
• Update platform-related SDKs (e.g., compile iOS & tvOS libraries with later versions)
• Cross-platform compatibility re-validated on the latest versions of Windows, macOS, iOS, tvOS, and Android
• All wallet transactions are functional, work across all supported providers, and self-hosted solutions

Documentation & Education:

• Comprehensive GitHub documentation with setup guides and API reference
• Video tutorial series covering basic to advanced integration scenarios
• Code examples and starter templates for common use cases
• Troubleshooting guides and the FAQ section

Evidence of Completion

Providing deliverables including updated GitHub repository with comprehensive documentation, published tutorial videos, successful cross-platform testing results, and community adoption metrics demonstrating production readiness:

• GitHub repository with updated documentation and examples
• Published video tutorials demonstrating functionality
