Does your project have any dependencies on other organizations, technical or otherwise?
Yes
Describe any dependencies or write 'No dependencies'
The project is built using the model context protocol, a standard for LLM Agents. It also uses pycardano an blockfrost for interating with the blockchain. The wallet will be generalizable to any MCP-compliant desktop A.I with proof of concept using Claude
Will your project's outputs be fully open source?
Yes
License and Additional Information
MIT License
Please choose the most relevant theme and tag related to the outcomes of your proposal
AI
Mention your open source license and describe your open source license rationale.
Lextra Wallet will be released under the MIT License, ensuring maximum freedom for developers and the community to use, adapt, and extend the codebase. This permissive license supports innovation, rapid adoption, and collaboration by removing unnecessary restrictions while maintaining attribution to the original project.
How do you make sure your source code is accessible to the public from project start, and people are informed?
The Lextra Wallet code will be hosted in a public GitHub repository from project inception. All commits, branches, and issues will be visible to the community, with regular updates reflecting development progress. This transparency allows for community review, contributions, and early feedback at every stage.
How will you provide high quality documentation?
We will provide comprehensive documentation using an open-source static site generator. It will cover setup, wallet features, API references, security considerations, and contribution guidelines. Clear examples, diagrams, and regular updates will ensure developers and users can easily understand and integrate Lextra Wallet.
Please describe your proposed solution and how it addresses the problem
Lextra Wallet integrates Cardano functionality directly into AI desktop clients like ChatGPT and Claude via MCP. It enables wallet creation, transaction signing, staking, and token management from within the AI interface, lowering onboarding friction for AI-first users and bridging blockchain with conversational AI workflows.
Please define the positive impact your project will have on the wider Cardano community
Lextra Wallet expands Cardano adoption by embedding it into emerging AI-first computing platforms. Developers gain an open-source integration layer, accelerating dApp experimentation. Users can onboard without separate apps, boosting engagement and visibility for Cardano. It also serves as a reference implementation for AI–blockchain interaction.
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?
Developed by a solo founder with a PhD in machine learning and over a decade of professional software engineering experience and a proven track record in AI integration. Open-source development on GitHub ensures transparency, and milestones with public demos validate delivery.

Please provide a cost breakdown of the proposed work and resources
Render Hosting Membership – $19/month → ≈38 ADA/month → 228 ADA/year
Blockfrost API Membership – €79/month → ≈174 ADA/month → 1,044 ADA/year Claude AI Pro Membership – $20/month → ≈40 ADA/month → 240 ADA/year Combined Infrastructure: ~₳1,512/year
• Allocate ₳5,000 for bug bounties and user testing incentives.
• The remaining ₳43,488 will cover full-stack development, MCP integration, staking/voting/asset features, UI/UX improvements, and deployment over the project period.
How does the cost of the project represent value for the Cardano ecosystem?
Lextra Wallet delivers a high-impact capability to the Cardano ecosystem at a modest cost. For ₳50,000, the project will create the first AI-integrated Cardano wallet for major AI desktop clients like ChatGPT and Claude, unlocking direct blockchain access for millions of potential new users.
The budget goes toward development, feature delivery, security, and community testing, with infrastructure costs kept under ₳1,512/year. This ensures that almost every ADA spent results in tangible, long-lived improvements to the ecosystem.
The wallet will be released open-source, enabling the community to build on the codebase, integrate it into their own AI-powered solutions, and accelerate adoption of Cardano in the AI space without repeated funding. This one-time investment creates a scalable, reusable asset with compounding value—making it a cost-efficient way to expand Cardano’s reach and utility.
