Thanks a lot for the application. This looks interesting to me and is something that we want to support. I have only two minor comments: Would you be willing to accept only USDC on Polkadot to a single address? We recently updated this. Additionally, could share a post address with us via [email protected] or add it to the document?

[justinfrevert]

Hi @Noc2, I updated the payment address, and sent an email with the postal address.

Thank you for the application, @justinfrevert. Sounds interesting. I just have some minor change requests.

[semuelle]

Could you describe what your personal relationship to/interest in this project/idea is? Are you intending to use it yourself?

[justinfrevert]

We're just excited in the ZK ecosystem, and want to build on it in Substrate. This would mainly be for sharing and learning. We like to experiment with similar ideas, so there's a chance we may build on it in the future when working on something similar.

Hi @Noc2 @semuelle , we re-evaluated our proposal and came to the conclusion that 10k is a bit low for 3 months of complex work for 2 devs. We would like to propose our grant as level 2, for 20k instead.

[semuelle]

Thanks for the updates, @justinfrevert. I'm afraid that our experience shows that projects without a clear roadmap are, more often than not, quickly forgotten after a grant unless they quickly attract a large audience. I would recommend finding a project, or ideally multiple, that would be interested in leveraging and continuing this work.

However, I am going to mark your application as ready for review and share it with the rest of the committee.

Thanks a lot for the application and all the effort you put into this. The grants committee decided to close your application, partly due to the above reasons. Independent of it, we wish you all the best for your project.
