Mention your open source license and describe your open source license rationale.

The project will be fully open source under the MIT License.

MIT License Rationale:

The MIT License is simple, permissive, and widely used in the open source community. It allows developers to freely use, modify, and share the code without restrictions. This makes it easy for others to contribute, adapt, or integrate the toolkit into their own projects. By choosing MIT, we ensure that the Cardano developer community has full access to our work from day one, supporting transparency, growth, and collaboration.

How do you make sure your source code is accessible to the public from project start, and people are informed?

We have launche a public GitHub repository during the first the praparation of the project. The code, documentation, and templates will be uploaded as soon as they’re created. We'll share updates on the Cardano Forum, X (Twitter), and developer channels to inform the community that the project is live and open from day one.

How will you provide high quality documentation?

We’ve dedicated part of the budget specifically to documentation and tutorials. A technical writer on our team will create clear, step-by-step guides, code comments, and usage examples for every contract template. These will be hosted on GitHub and shared through community channels. We'll also make walkthrough videos to support visual learners and gather community feedback to keep improving the content.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

Our solution is a toolkit that helps Ethereum (EVM) developers move their smart contracts to Cardano without needing to learn everything from scratch. Right now, developers who are used to the account-based model of Ethereum find it hard to work with Cardano’s extended UTXO (eUTXO) model. The two systems are very different, and there’s no easy way to translate common Solidity contract structures into Cardano-compatible formats.

We want to fix this by building a tool that takes well-known Solidity patterns like ERC-20 tokens, access control, and modifiers and turns them into working examples in Aiken or Plutus, which are languages used on Cardano. These examples will follow the eUTXO model and will be fully documented.

This toolkit will include:

• A pattern translation engine that maps Solidity to Cardano contract templates.
• A simple web interface where developers can select a Solidity pattern and see its Cardano equivalent.
• Tutorials, code comments, and detailed guides to help developers understand and use the templates.
• An open source GitHub repository available from the start, with clear licensing (MIT License).

By doing this, we make it easier for developers to:

• Reuse code logic they already understand.
• Learn how Cardano’s smart contract system works through side-by-side comparisons.
• Experiment on Cardano without needing to master everything about eUTXO upfront.

In short, this project helps remove a big barrier: it shows EVM developers how to “speak Cardano” by example. It helps them translate their knowledge, not just their code, and that speeds up adoption and innovation in the Cardano ecosystem.

[Your Project and Solution] Impact

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

The EVM-to-eUTXO Contract Translator Toolkit will have a strong, positive impact on the broader Cardano community by helping developers from other ecosystems, especially Ethereum to feel more confident and welcome building on Cardano.

Here’s how:

1. Lowering Entry Barriers: Right now, many developers find it hard to understand how to build on Cardano. This toolkit gives them a familiar starting point by translating well-known Solidity patterns into Cardano’s Plutus and Aiken smart contracts. Instead of starting from zero, they’ll be able to build with tools that feel familiar.
2. Growing the Developer Ecosystem: By making it easier to build on Cardano, we help increase the number of developers active in the ecosystem. This means more apps, more experiments, and more community innovation.
3. Encouraging Multi-Chain Projects: Some developers want to build apps that work on more than one blockchain. With our toolkit, they’ll be able to bring their Ethereum-based ideas and easily deploy them on Cardano, which boosts Cardano’s visibility and usage.
4. Boosting Open Source Reuse: Everything we build is open source, so anyone can reuse, remix, or build on top of our work. This increases collaboration, speeds up development for others, and prevents everyone from having to reinvent the wheel.
5. Increasing On-Chain Activity: With more developers building real apps faster, we expect more smart contracts and transactions on Cardano. This leads to stronger network usage and showcases Cardano’s strengths in security and scalability.
6. Supporting Education and Learning: The toolkit comes with clear documentation, code comments, and step-by-step guides. It helps not just experienced developers but also newcomers who are curious about Cardano and want to learn by doing.
7. Creating a Gateway for Solidity Developers: There are thousands of Solidity developers in the world. If even a small percentage start building on Cardano thanks to this toolkit, that’s a huge win for the ecosystem.

In short, this project creates a much-needed bridge between Ethereum and Cardano. It brings people in, supports them with helpful tools, and grows the ecosystem in a healthy, open, and collaborative way.

[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?

We have a capable and experienced team made up of smart contract developers, Solidity engineers, frontend developers, and technical writers. Each team member brings direct experience with both the Ethereum and Cardano ecosystems. This means we understand both ends of the bridge we’re trying to build.

To ensure a high level of trust and accountability:

1. Transparent Development

• We will open our GitHub repository from the start and push updates continuously.

• Anyone will be able to see the code, follow progress, and contribute.

• Milestones and deliverables will be publicly tracked, so the community can hold us accountable.

  1. Clear Communication

• We’ll provide regular updates on the Cardano Forum and social platforms.

• Feedback from the community will be welcomed and used to improve the toolkit.

• Every key decision like template priorities or changes in approach will be explained openly.

  1. Open Source Commitment

• Everything will be released under the MIT License, so the community knows the work is 100% open and free to use or improve.

• We’ll publish clear documentation, tutorials, and video guides for each major release.

  1. Feasibility Validation

We know this project is technically achievable because:

• We’ve already tested small examples translating Solidity logic into eUTXO-style smart contracts in both Aiken and Plutus.
• The translation engine will focus on a limited, manageable set of common patterns like ERC-20, so we’re not overpromising.
• We’re using existing tools (like solidity-parser-antlr for pattern reading and Lucid for Cardano interaction) to avoid building everything from scratch.

We’ll also run real-world tests during development by:

• Deploying translated contracts on Cardano testnet.
• Involving other developers in testing and giving feedback.
• Measuring how easily Solidity developers understand and use the results.

In summary, we’re building something practical, with tools we’ve already worked with, and we’re doing it in the open. That’s how we ensure trust, feasibility, and real value for the Cardano community.

[Final Pitch] Budget & Costs

Please provide a cost breakdown of the proposed work and resources

Cost Breakdown of Work and Resources:

Budget Item Amount(ADA) Description

---

Dev Salaries (5 developers) ₳48,000 3 developers (blockchain, web2, web3, backend, fullstack) working full-time over months

---

Technical Writing & Documentation ₳10,000 Technical writer responsible for creating templates, guides, inline docs, and tutorial content.

---

UI/UX & Frontend Development ₳12,000 Design and development of the toolkit’s user interface and pattern browsing web app.

---

Community Outreach & Content ₳5,000 Forum posts, dev-focused tweets, explainer videos, community feedback sessions.

---

Testing and QA ₳5,000 Functional testing, testnet deployments, template validation, and user feedback cycles.

---

Contingency Reserve ₳5,000 Covers unplanned dev time, updates due to library changes, or hiring for specific gaps.

The budget is distributed across the 11months project timeline to ensure consistent development, testing, and documentation from start to finish. Additional team members (Cardano and Ethereum devs) will be compensated from within the dev salary and contingency allocations depending on hiring timelines and part-time rates.

[Final Pitch] Value for Money

How does the cost of the project represent value for the Cardano ecosystem?

This project offers strong value for money by targeting a major onboarding barrier: helping Solidity developers transition to Cardano. By building an open-source toolkit that translates Ethereum contract patterns into eUTXO-compatible templates, we enable more developers to create on Cardano without needing to become protocol experts.

With ₳85,000 spread across 11 months, we ensure:

A complete developer-friendly toolkit (10+ templates) usable across projects

A public web interface to increase visibility and access

Clear documentation and tutorials to reduce developer onboarding time

Community engagement via testing and feedback loops

The biggest cost component (₳48,000) supports developer time, split among core team members and two additional hires with expertise in both ecosystems. This makes the solution technically sound, time-efficient, and collaborative.

Given that some Plutus/Aiken contract development can cost tens of thousands per contract alone, creating a reusable library of 10+ patterns ready for integration is a significant multiplier for ecosystem value.

All work will be open source and available from day one. We also emphasize community involvement and feedback throughout development. This ensures the toolkit will be adopted and adapted by real developers and projects.

Rather than one closed product, this project creates an extensible foundation that other builders can build upon, customize, and improve—helping grow Cardano’s developer ecosystem in a sustainable and scalable way.
