Gaia Carbon Project

All blockchain dependencies for this project were deployed or configured on the Polygon Mumbai network.

Project Sequence Diagram

Setup

  1. Metamask funded with LINK tokens - (faucets.chain.link). Also, ensure you have enough test Mumbai Matic

  2. Install NPM and Node > v 17

  3. Create an Alchemy account, create an app, and get the keys

  4. The following environment variables should be readily available (check the env.example file to see which ones you will need and what name they are given):

The following ENV VARIABLE values
ALCHEMY_WSS_URL=
ALCHEMY_RPC_URL=
PRIVATE_KEY=

Set your environment variables using the env-enc package included.

  1. Set password (this password will be used to encrypt the environment variables and decrypt too) with npx env-enc set-pw. Remember this password otherwise you will have to set the env vars each time!
  2. Set the above-mentioned env vars with npx env-enc set ...and then follow the prompts
  3. After you set all the env vars, you can view the decrypted, human-readable version by running npx env-enc view

Note Each time you open a fresh terminal or restart a terminal session you will need to run npx env-enc set-pw but not the other steps.

Contracts

We have deployed some contracts, we give the smart contracts address to make it possible see them on the Mumbai network scan:

  1. Gaia Carbon Functions Consumer: https://mumbai.polygonscan.com/address/0x0dc1b5cb19095bb39c6740615a2995eb67226955
  2. Gaia Carbon NFT: https://mumbai.polygonscan.com/address/0x83CDA4fee13B2e7F59186013035E00de0eAD8d3A

Subscriptions

We have created the following subscriptions:

  1. Chainlink VRF: https://vrf.chain.link/mumbai/6675
  2. Chainlink Functions: https://functions.chain.link/mumbai/1079

NFE Service

We have built a service to generate a fake Brazil electronic fiscal document that represents a purchase that some company made, and for the Gaia Carbon project, the purchases were related to a Wood for burn and the NCM 44011000 (universal product number) was used to filter only specific product that the project will use in a real project.

Bellow, some curl commands example to see the API's in the production:

  1. Get NFE's: 
    curl 'https://nfe-service-hackathon-e1676ada9c11.herokuapp.com/v1/api/nfes' \
-H 'Accept: application/json'
  2. Get the newest generated NFE for some company: 
    curl 'https://nfe-service-hackathon-e1676ada9c11.herokuapp.com/v1/api/nfes/ncm/44011000/carbon-free-calculation' \
-H 'Accept: application/json'

OpenSea NFT Marketplace

The minted NFTs have been displayed on the OpenSea marketplace for the Gaia account: https://testnets.opensea.io/GaiaSustainability
