[METADATA] Horizons

Standards

[SOLUTION] Please describe your proposed solution

Our solution is to develop a user-friendly interface that allows users to search for UTXOs on the Cardano blockchain and visually construct transactions.

Main features:

• Search UTXOs: Input wallet addresses to retrieve associated UTXOs with detailed information.
• Visual Transaction Builder: Visually construct transactions, including creating partial transactions or "transaction templates."
• QR Code Generation: Create QR codes representing the serialized total for partial transactions that can be scanned by wallets, which will then add the missing inputs and balance for signing and submission.

Reasons for Our Approach:

• Accessibility: By providing a visual interface, we lower the barrier to entry for users without technical expertise.
• Simplification: Streamlines the complex process of transaction construction, especially for smart contracts.
• Community Engagement: Encourages broader participation in the Cardano ecosystem.
• Enhanced Functionality: By allowing partial transactions, we cater to a broader range of use cases.
• User Empowerment: Simplifies complex transactions, making advanced blockchain interactions accessible.
• Ecosystem Growth: Facilitates activities like delegation and NFT minting, contributing to the Cardano ecosystem's expansion.

Who Will Benefit:

• General Users: Individuals looking to manage their Cardano assets more effectively.
• Developers: Those who can build upon our open-source code.
• Educators: Can use the tool for teaching purposes.
• NFT Creators: Can be used as a tool for generating QR codes for minting transactions.
• SPOs : Generating QR codes for delegation transaction
• DReps: Generating QR codes for delegation transaction

Demonstrating Impact:

• User Metrics: Track the number of transactions constructed and submitted.
• Feedback Loops: Collect user feedback to continuously improve the platform.

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

Our project will enhance the Cardano ecosystem by:

• Simplifying Delegation: Makes it easier for users to delegate to DReps and SPOs via QR codes.
• Streamlining NFT Minting: Simplifies the process for users to mint NFTs by scanning a QR code provided by creators.
• Enabling New Use Cases: Opens doors for various applications requiring transaction templates.
• Increasing Accessibility: Simplifies blockchain interactions for non-technical users.
• Driving Adoption: Encourages more users to participate in the network.
• Supporting Developers: Provides open-source code for further innovation.

Measuring Impact:

• Quantitative Metrics: Number of users, transactions constructed, and transactions submitted.
• Qualitative Feedback: User surveys and community engagement to assess satisfaction.

Sharing Outputs:

• Open Source Repository: All code will be available on GitHub under the GPLv3 License.
• Community Engagement: Active participation in forums and collaboration with other projects.

[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 have graduated from the Emurgo Academy's Cardano Solutions Architect program and recently successfully completed a Catalyst-funded open-source project for a Cardano DApp, utilizing Haskell and Plutus (Project ID 1000064).

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

[BUDGET & COSTS] Please provide a cost breakdown of the proposed work and resources

Costs represent 1 average wage (for 1 dev ..me) for 12 months.

[VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

The investment for the transaction templates feature significantly enhances the ecosystem adoption, offering:

• Expanded Use Cases: Supports DReps, SPOs, NFT creators, and other entities, fostering ecosystem growth.
• Increased Adoption: Simplifies critical functions like delegation and NFT minting, encouraging more users to participate.
• Open Source Contribution: Provides valuable tools and code for the community to build upon, multiplying the project's impact.

Given the broader reach and potential for driving significant user engagement, the costs represent excellent value for the Cardano community.
