[dsm-w3f]

Thanks @semuelle I'll take a look at this evaluation.

@leonardocustodio thank you for the milestone delivery. Please take a look at the evaluation document in this pull request and provide proper answers and fixes. Let me know when I can continue this evaluation.

Hey @dsm-w3f Sorry for the trouble, the fixes are now done and is ready to be tested again.

@dsm-w3f
Also on the sr25519:
We think writing in pure dart code was a good choice although it took intensive testing and hours.

• Writing in pure dart makes it easy to maintain codebase with lesser dependencies.
• Bridging rust to flutter still lacks supports for some parts of intermediate code generation.
• Good amount of refactoring would be needed to align current code with async native calls.
• With code written in pure dart, it enables to cover all the platforms and provide fixes without depending on 3rd parties.

@dsm-w3f
For the docker: surprisingly it worked on my side, I guess it’s a low memory issue maybe.
Can you try, giving higher swap and memory in docker-settings -> resources….

Thanks for your time.

[dsm-w3f]

@justkawal thank you for the answers and fixes. I updated the evaluation document. I'm still having problems to run the metadata automated tests. Could you please inform what is the configuration of the machine that you was able to run this tests? Please see more details in the evaluation document in this PR.

Hey @dsm-w3f,

Seed (Dev-Phrase): bottom drive obey lake curtain smoke basket hold race lonely fit walk

Derivation paths for signatories are: //TeslaS1, //TeslaS2, //TeslaS3
Derivation paths for receiver account: //TeslaR

So in the latest update to main branch, I had mentioned the seed (dev-phrase) in the comment in the file multisig_example.dart: (3 days ago) https://github.com/leonardocustodio/polkadart/blob/020eae9fae70e71f838eb94623b43993de223b19/packages/polkadart/example/multisig_example.dart#L8

Also as I can see in the issue image of multisig_example.dart at line 26, So now in the updated code, line 26 is having comment and not any code.
Here: https://github.com/leonardocustodio/polkadart/blob/020eae9fae70e71f838eb94623b43993de223b19/packages/polkadart/example/multisig_example.dart#L26

So, It seems that main is not up-to-date, Please can you do a git pull again from the main branch again or a fresh clone maybe?

Thank you so much for your time.

[justkawal]

@dsm-w3f
Also to test and run the multisig example, we don't need polkadart_cli as we're not using it in that respective example.
So, to run and test multisig_example.dart, you can just run dart pub get inside that package and then run that multisig_example.dart file.

For the issue in examples: To add polkadart_cli and polkadart in pubspec.yaml
I guess I already fixed that previous week: https://github.com/leonardocustodio/polkadart/blob/020eae9fae70e71f838eb94623b43993de223b19/examples/pubspec.yaml#L30

So, maybe just needs a git pull, or a fresh clone.

Thank you so much. ❤️

[dsm-w3f]

@justkawal thank you for the answer. Now it worked for me. The evaluation document was updated in this PR. It would be nice to have these instructions added to the documentation. The only point that is still pending in this evaluation is the memory problem while running the automated tests. Please let me know when I can continue this evaluation.

[justkawal]

@dsm-w3f
Sure, I'll have a look into the memory thing today. Sorry about that.

Either way, can you try? with:

dart pub global activate melos

melos test

[dsm-w3f]

@justkawal I tried these commands and the behavior was the same as running using docker. The memory is consumed until get all memory from the machine.

[justkawal]

@dsm-w3f
Thanks for the timely feedback.
I will try something to lower the memory usage.

[justkawal]

@dsm-w3f
Can you do a pull and try again?
I tested it on a lower memory system now and it seems to be working fine.

Note: (It might take some time to build around (8-9 mins))

Thank you.

[dsm-w3f]

@justkawal thank you for the improvements and fixes. It worked now. I updated the evaluation document in this PR. Great job! @semuelle this evaluation is accepted by my side and the evaluation PR is open.

[justkawal]

@dsm-w3f @semuelle
Thank you so much for your time team.
💯🎉

[leonardocustodio]

I'm just filling the form, all milestones we have received as USDC-ERC20, isn't that possible anymore? We must always used AssetHub now?

[keeganquigley]

Hi @leonardocustodio yes that's correct, our payment options changed recently and we no longer offer ETH mainnet payments. Does this work for you?

[leonardocustodio]

Ok @keeganquigley , I've submitted the invoice with the new address and also sent a PR amending the application with the new address: w3f/Grants-Program#2245

[keeganquigley]

Thanks @leonardocustodio much appreciated, your milestone evaluation has been passed but I will wait for the amendment to be approved before merging the delivery to avoid any confusion. Congrats on finishing the grant!

[semuelle]

Amendment and evaluation are merged, milestone is accepted. Congrats, @leonardocustodio.

🪙 Please fill out the invoice form in order to initiate the payment process. Thank you!

We noticed that this is the last milestone of your project. Congratulations on completing your grant! 🎊

So, where to from here? First of all, you should join our Grants Community chat, if you haven't already, so we can stay in touch.
If you are looking for continuative support for your project, there are quite a few options. The main goal of the W3F grants program is to support research as well as early-stage technical projects. If your project still falls under one of those categories, you might want to apply for a follow-up grant. However, depending on your goals and project status, there are other support programs in our ecosystem that might be better suited as the next step. For example, projects with a Business Case/Token should look into the Substrate Builders Program or VC Funding and Common Good projects have a good chance of receiving Treasury Funding. If you are looking for guidance, the team at https://substrate.io/ecosystem/square-one/ has compiled a list of ecosystem support sources and are happy to help you navigate it.

For a more comprehensive list, see our Alternative Funding page. Let us know if you have any questions regarding the above. We are more than happy to point you to additional resources and help you determine the best course of action.
Lastly, we hope your W3F grant was a success and we want to thank you for being part of the journey!
