[GENERAL] Please indicate if your proposal has been auto-translated into English from another language

[GENERAL] Summarize your solution to the problem (200-character limit including spaces)

This SDK will provide Godot developers with tools for seamless integration with Cardano, including APIs, WebGL templates, and sample dApps, facilitating easy and efficient game development.

[GENERAL] Does your project have any dependencies on other organizations, technical or otherwise?

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.”

The project relies on public APIs to interact with the Cardano Blockchain. To mitigate potential issues, we will develop integrations with multiple APIs, specifically Blockfrost and Koios.

[GENERAL] Will your project’s output/s be fully open source?

[GENERAL] Please provide here more information on the open source status of your project outputs

Assets will be released under the MIT license and hosted on GitHub.

[SOLUTION] Please describe your proposed solution

This project will develop a comprehensive SDK that includes Godot WebGL templates, and GDScript code for seamless integration with Cardano APIs, tailored for game developers. This will include:

• 2 WebGL Templates for creating Cardano dapps that interact with Godot
• "Cardano Basic" - A minimal WebGL template that includes the necessary boilerplate code to connect a Cardano Wallet to your Godot App
• "Cardano Responsive" - Responsive version of Cardano Basic that resizes the Godot App for various window sizes, mobile, etc.
• GDScript code to interact with Blockfrost API
• GDScript code to interact with Koios API
• 3 demo dapps that can be used as a templates for common use cases:
• Using NFTs for gated access
• Awarding in-game tokens
• Minting NFTs and Caradano Native Tokens.

In addition to development, we will provide ongoing support through GitHub, aiding developers in leveraging the SDK for their specific needs.

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

The SDK will not only simplify development but also significantly reduce the time and resources needed to prototype and deploy Cardano-based games, fostering innovation and attracting new developers to the ecosystem. This will increase the pool of developers for Cardano, as well as provide high-quality and time-saving resources for existing developers, resulting in more and better Cardano dapps.

Additionally, this SDK will serve educational purposes, helping new developers understand blockchain applications in gaming through practical examples and real-world use cases.

[CAPABILITY & 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?

I've been a professional game developer for over 15 years, developing on Cardano since 2021. I've developed multiple games that integrate with Cardano.

This project will provide the tools I wish I had when I started working with Cardano.

These assets will save new developers months of development for creating their Cardano Dapps.

Project success will be continuously evaluated through developer feedback and usage metrics, ensuring that the SDK meets the evolving needs of the community.
