[IMPACT] Please describe your proposed solution.

We have a goal of facilitating atomic swaps between Cardano and other blockchains using a protocol that combines signatures and timelocks. Here's an illustration: Alice wants to purchase 1,000 ADA with 1 ETH. Instead of relying on a centralized exchange or bridge, Alice submits an offer on the Ethereum blockchain. Bob, who may want to exchange 1 ETH for ADA, notices the offer and submits a corresponding offer on the Cardano blockchain. They proceed to exchange digital signatures, either on-chain or off-chain, ensuring that only one of two outcomes is possible: a) Alice and Bob both receive their assets, or b) the transaction is fully reverted. In scenario a), Alice receives her ADA on the Cardano blockchain, and Bob receives his ETH on the Ethereum blockchain. In scenario b), no value is transferred between blockchains. It's important to note that the assets being exchanged remain on their respective native blockchains and are not held in custody, thereby minimizing associated risks. Additionally, the assets don't require wrapping or unwrapping, making the process easily understandable for non-technical users. Alice or Bob can choose to become a market maker, eliminating the need for vulnerable bridge liquidity pools. Although this protocol is generic, our plan is to provide a proof of concept implementation for EVM and Plutus, which are familiar to most developers. We have already conceived a few possible variations of this protocol.

[IMPACT] How does your proposed solution address the challenge and what benefits will this bring to the Cardano ecosystem?

Benefits to the Cardano ecosystem:

1. Interoperability: The proposed solution will enhance the interoperability of Cardano with other blockchains, allowing for seamless asset transfers and fostering collaboration between different blockchain ecosystems.
2. Accessibility: By enabling atomic cross-chain swaps, the solution will make it easier for users to access and participate in the Cardano ecosystem, attracting a broader user base and increasing adoption.
3. Security: The protocol's design, including the use of signatures and timelocks, ensures secure and trustless transactions, minimizing the risk of fraud or loss of assets during cross-chain swaps.
4. Decentralization: The solution promotes decentralization by eliminating the need for centralized intermediaries or liquidity pools, empowering individuals to directly exchange assets across blockchains.
5. Developer Tools: As part of the proposal, the team plans to provide a proof of concept implementation for EVM and Plutus, which will contribute to the development of tools and software for developers working on Cardano. This will facilitate the creation of decentralized applications (DApps) and smart contracts on the Cardano blockchain.

By addressing the challenge of interoperability and providing efficient cross-chain swaps, the proposed solution will have a positive impact on the Cardano ecosystem, promoting accessibility, security, and collaboration within the DeFi space.

[IMPACT] How do you intend to measure the success of your project?

To measure the success of the proposed project, we will track and evaluate the following key metrics:

1. Adoption and Usage: We will monitor the adoption rate of the atomic cross-chain swap protocol among users and projects within the Cardano ecosystem. This will include tracking the number of successful cross-chain swaps executed using the protocol and the volume of assets transferred. Increasing adoption and usage will indicate the value and practicality of the solution.
2. Interoperability: We will assess the level of interoperability achieved by measuring the number of different blockchains that successfully integrate with Cardano through the atomic swap protocol. The more blockchains that can seamlessly interact with Cardano, the greater the level of interoperability and connectivity within the ecosystem.
3. Security and Trust: We will conduct rigorous security analysis and testing to ensure the protocol's resilience against potential vulnerabilities and attacks. The success will be measured by the absence of security breaches and the ability of the protocol to securely facilitate cross-chain swaps without the risk of asset loss or fraudulent transactions.
4. Developer Adoption: We will gauge the interest and adoption of the protocol by developers within the Cardano ecosystem. This will involve tracking the number of projects and developers utilizing the protocol for building decentralized applications and integrating with other blockchains. Increased developer adoption indicates the usefulness and relevance of the solution for expanding the Cardano developer community.
5. Community Feedback: We will actively seek feedback from the Cardano community, including developers, users, and stakeholders. This feedback will provide insights into the user experience, satisfaction, and any areas that may require improvement. Positive community feedback and engagement will reflect the benefits of the project for the Cardano ecosystem.

By tracking and measuring these metrics, we will be able to assess the project's progress, its impact on the Cardano ecosystem, and validate the success of the proposed solution. Regular reporting and sharing of results with the community will ensure transparency and accountability throughout the project's execution.

[IMPACT] Please describe your plans to share the outputs and results of your project?

We have a comprehensive plan to share the outputs and results of our project with the Cardano community and beyond. Our goal is to ensure transparency, knowledge dissemination, and engagement with stakeholders. Here are our plans:

1. Documentation: We will prepare detailed documentation that describes the cross-chain swap protocol, its technical specifications, implementation guidelines, and security considerations. This documentation will be made available in a user-friendly format to enable easy understanding and implementation by developers and enthusiasts.
2. Open Source Repository: We will create a dedicated open-source repository on GitHub to host the codebase of the reference implementation of the protocol. This repository will be publicly accessible, allowing developers to explore, review, and contribute to the project. By open-sourcing the code, we aim to foster collaboration and community involvement.
3. Community Engagement: We will actively engage with the Cardano community through various channels, including forums, social media platforms, and developer communities. We will participate in discussions, address questions, and gather feedback to foster a collaborative environment. Community feedback will be valued and considered for future enhancements and iterations of the protocol.
4. Collaboration and Partnerships: We will actively seek collaboration and partnerships with other projects, developers, and organizations within the Cardano ecosystem and the broader blockchain community. Through collaborations, we can leverage synergies, share knowledge, and collectively contribute to the advancement of cross-chain interoperability.

By implementing these strategies, we aim to ensure that the outputs and results of our project are widely accessible, well-documented, and actively shared with the Cardano community. We believe that open communication, collaboration, and knowledge dissemination are vital for the successful adoption and utilization of our proposed atomic cross-chain swap protocol.
