DotLink: A Polkadot Lightweight IOT SDK

[abhiraj-mengade]

Project Abstract

DotLink is an open-source, lightweight SDK designed to enable seamless blockchain interactions for Internet of Things (IoT) devices using the Polkadot ecosystem. Our mission is to provide a minimal, efficient, and cross-platform solution for connecting resource-constrained devices to decentralized networks.

Application Checklist

• The application template has been copied and aptly renamed (project_name.md).
• I have read and followed the program guidelines.
• I am aware that, in order to receive a grant, I (and the entity I represent) have to successfully complete a KYC/KYB check.
• The software delivered for this grant will be released under an open-source license specified in the application.

Thanks for the application, @abhiraj-mengade. I will share it with the rest of the curators. Please note that the grants are provided in cohorts, so it might take some time before we provide concrete feedback.

@abhiraj-mengade thank you for sharing your proposal. We have a few technical and strategic questions to help us better understand the scope and potential impact of your project:

• You mention building an SDK for IoT devices, which can range widely. Which specific microcontrollers or platforms do you plan to target first? Do you envision support for bare-metal devices or primarily for real-time operating systems?
• Could you expand on how you plan to handle private keys and cryptographic credentials on resource-constrained hardware? How will keys be stored, and what security measures are you implementing for microcontrollers?
• From a technical standpoint, could you share more about how the microcontroller environment will connect to Polkadot? Are you considering any existing libraries or frameworks in C/C++ (e.g., Kagome) or building your own approach? A diagram or explanation of your architecture would help us understand the intended workflow.
• Can you provide any insight into how Dotlink fits in with or differs from other IoT-related projects in the Polkadot ecosystem? If there are any plans for collaboration or code reuse, we’d be keen to hear more.
• Who do you envision as the primary adopters of this SDK? Have you identified any early users, or is there existing interest within the Polkadot ecosystem that you can point to?
• Since IoT hardware varies widely, can you outline your roadmap or milestones in more detail? For instance, which boards or operating systems will be supported first, how do you plan to test or demo functionality, and what does your documentation plan look like?

We appreciate any additional details and are looking forward to your response!

Hi @semuelle, thanks a lot for the comments, sorry for the delay. We are working on the answers in detail along with doing more research, we will get back to you shortly.

@abhiraj-mengade, following up on our previous message: since we haven’t received responses to the questions above and we’re now closing this cohort, we’ll be rolling your application over to the next round. We’ll be happy to proceed with the evaluation once we hear back from you. Thanks!

[semuelle]

Any updates on this, @abhiraj-mengade?

[oshakarishvili]

I’ll go ahead and close this for now. Feel free to reopen or reach out again when you’re ready to proceed
