NOTES TO REVIEWERS:

This is one of 3 repositories of the project, the other two being https://github.com/mtsalenc/cipay-ui and https://github.com/mtsalenc/cipay-contracts.
I had thought about this project before the hackathon started, but it was not even close to functional and really just piling dust, I took the opportuninty to actually make it happen. The history of the project is preserved in git so you can see what each repo looked like before the hackathon started.

Backend

This service takes a meta transaction (transfering ETH from user to the service) + PIX qrcode and pays the QR Code.
