@salaheldinsoliman thanks for the milestone delivery. Please take a look at the evaluation document in this PR and provide proper answers and fixes. The application worked well, we just have a doubt about the scope of the milestone delivery. Let me know when I can continue this evaluation.

Hey @salaheldinsoliman, I am doing a cursory review of the evaluation. I tried compiling the example contract using the deployed version you link in the repo README, but I'm getting ERR_CONNECTION_REFUSED in the console. Might be related to the certificate warning I'm getting, but this is on both Firefox and Chrome. Am I missing something?

@semuelle Hello, can you please try edge instead? and make sure the connection is http is instead of https ?
This is temporary, as we have initiated conversations with Hyperledger labs to provide a suitable domain name.
Please let me know if you still have problems

Hi @salaheldinsoliman thanks for your help, I was able to get it to run on both the deployed (unsecured) version and at http://localhost:9000/

Unit tests are all passing but with a few warnings. Consider fixing these for the next milestone. Other than that I was able to reproduce everything, and since @ditavia-br has accepted your delivery, I'm happy to pass this milestone. Thanks for the nice work and looking forward to seeing UI improvements on the next one.
