Please describe your proposed solution

We propose developing an open-source SDK built on top of Anastasia Labs’ Lucid Evolution library. This SDK will enable developers to easily interact with the Indigo Protocol on the Cardano blockchain. The SDK will provide a set of tools and APIs for building and submitting transactions related to core Indigo Protocol functionalities such as:

• CDP (Collateralized Debt Position) Management: Allow developers to open, manage, and close CDPs on the protocol.
• Redemptions: Enable the redemption of synthetic assets and other assets on Indigo Protocol.
• Liquidations: Provide functionality to handle the liquidation process when CDPs become undercollateralized.
• Stability Pool Management: Offer tools for developers to interact with the stability pool, including deposits and withdrawals.
• Staking and Voting: Allow users to participate in Indigo Protocol’s governance by staking tokens and voting on governance proposals.

The SDK will be designed for ease of use, allowing developers to quickly integrate Indigo Protocol interactions into their dApps and platforms.

Our solution will include thorough documentation, examples, and community support to empower developers of all levels to use the SDK effectively.

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

The development of an open-source SDK for the Indigo Protocol will have several significant positive impacts on the wider Cardano ecosystem:

• Lowering Development Barriers: By providing a pre-built, well-documented SDK, we will lower the technical barriers for developers seeking to interact with the Indigo Protocol. This will encourage more developers to build applications on Cardano, expanding the utility and adoption of the network.
• Increased Adoption of DeFi on Cardano: Indigo Protocol is a key player in the Cardano DeFi ecosystem. An SDK that simplifies integration with the protocol will encourage more projects to build decentralized finance (DeFi) solutions, driving overall growth in the Cardano DeFi space.
• Open-Source Collaboration: By releasing the SDK as open-source, we will foster collaboration within the community. Other developers will have the opportunity to contribute to the project, propose improvements, and extend its functionality. This community-driven approach will ensure that the SDK evolves and remains relevant to the needs of the Cardano ecosystem.
• Education and Accessibility: Comprehensive documentation and example use cases will make it easier for new developers to learn how to build on Cardano, helping to grow the developer base. In turn, this will lead to a more vibrant and skilled community of developers contributing to the Cardano blockchain.

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?

As the core developers behind Indigo Protocol, our team is uniquely positioned to deliver this project with the highest levels of trust, expertise, and accountability. We have an in-depth understanding of the protocol’s architecture, having successfully designed, developed, and launched various components that power the Indigo DeFi ecosystem. This gives us a significant advantage in creating an SDK that is efficient, secure, and fully aligned with the protocol’s needs.

Our experience in delivering mission-critical projects within the Cardano ecosystem underscores our capability to manage this initiative effectively. We have consistently met development timelines, produced high-quality open-source software, and contributed to the growth of DeFi on Cardano.

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

This project offers significant value for money for the Cardano ecosystem due to several key factors:

• Multiplying the Impact of DeFi Growth: As a critical enabler of decentralized finance (DeFi) projects on Cardano, this SDK will contribute to the expansion of DeFi activities in the ecosystem. By simplifying the process of building on top of Indigo Protocol, we will help unlock new use cases, products, and services, which can generate more economic activity on the network. The ripple effect of this project could lead to increased transaction volume, greater token utility, and the growth of the Cardano DeFi ecosystem, all of which add substantial value.
• Open-Source Contribution: By making this SDK open-source, we provide the developer community with an example of a dApp on Cardano.

In summary, the project’s cost is justified by its potential to significantly accelerate DeFi adoption on Cardano, its reuse potential across multiple projects, and its long-term value as an open-source tool available to the entire developer community.
