**Introduction:**

We're excited to introduce our latest proposal focusing on the implementation of new developer tools using the Polkadot-API (PAPI). At LimeChain, we recognize the pivotal role developer tools play in simplifying workflows and enhancing the experience of developers within the blockchain ecosystem. With the emergence of PAPI, a light-client first JS API for interacting with Polkadot and other Substrate chains, we see an opportunity to revolutionize developer tools and accelerate the adoption of PAPI.

**We Propose the Following**: Creating a Next-Gen Developer Tools Application

Our proposal aims to create a developer tools application that serves as the primary platform for developers to explore on-chain information seamlessly across the entire Polkadot ecosystem. This application will feature a dedicated integrated development environment (IDE) for rapid prototyping using PAPI, providing users with a comprehensive and intuitive experience. By leveraging the power of PAPI, we aim to showcase its capabilities and facilitate its wider adoption among developers.

The implementation of this developer tools application will not only accelerate the adoption of PAPI but also enhance the performance and user experience (UX/DX) of developers interacting with the Polkadot ecosystem. By recreating familiar functionalities from existing tools like Polkadot.js UI and improving upon them, we aim to create a next-gen application that becomes a daily essential for developers and regular users alike.

**Key Features**:

Key features of the application include seamless exploration of the Polkadot ecosystem, an integrated IDE for rapid prototyping, and future-ready extensibility. With a focus on real-time exploration tools and an intuitive user interface, this application will set a new standard for developer tools within the Polkadot ecosystem.

The application will be built using Next.js for the front-end, providing a robust framework for full-stack web development. We'll leverage the capabilities of Polkadot-API for seamless interaction with the Polkadot network, and NestJS for building efficient and scalable server-side applications. Additionally, we'll utilize Kubernetes, Docker, and Grafana for infrastructure management and monitoring.

**Milestones**:

The project will be divided into milestones, each focusing on specific aspects such as application setup, IDE development, real-time block explorer, chain state, RPC and runtime calls, and SCALE messages encoder and decoder. Additionally, we'll utilize Kubernetes, Docker, and Grafana for infrastructure management and monitoring.

**Future plans:**

Beyond the initial scope, we have plans to implement additional features such as saving, loading, and sharing IDE prototypes, session sharing within the IDE, and more cross-functional integration between different pages and modules. We'll gather feedback from the community to ensure the application meets the evolving needs of developers and users within the Polkadot ecosystem.

The success of the project will be measured based on the achievement of key deliverables outlined in the milestones, as well as metrics such as user engagement and feedback. We'll ensure transparency and ongoing communication with the community through regular updates and announcements.

**Conclusion**:

At LimeChain, we believe in the principles of interoperability and decentralization, which are fundamental to the Polkadot network. With our extensive experience in developing tools and infrastructure implementations across various ecosystems, we're confident in our ability to contribute to the growth and success of the Polkadot ecosystem.

Our team comprises experienced professionals with a strong background in software development, blockchain technology, and developer tooling. With a collective vision for enhancing the Polkadot ecosystem, we're committed to delivering impactful solutions that benefit developers and users alike.

In conclusion, our proposal represents a significant step towards building the future of developer tools within the Polkadot ecosystem. By leveraging the capabilities of PAPI and adopting a user-centric approach, we aim to create a next-gen application that empowers developers and accelerates the adoption of Polkadot.
