Greenade

Greenade is a decentralized carbon credit platform that allows customers to buy carbon credits from producers using tokens. The platform consists of four smart contracts written in Solidity:

1. CarbonRegistry - This is the smart contract where various companies can come and provide proof that they generated mWH of electricity and put it on the blockchain.
2. Verifier - This is a smart contract where authorized verifiers can verify that the projects uploaded in the registry are legit and can approve the same using a multi-sig mechanism.
3. Token - This is a normal ERC20 token, which is minted every time a project is verified, proportional to the mwh generated and is burnt when a customer wants to avail the carbon credit NFT.
4. AMM - This is a smart contract used for market making the Token with stable coins or in this case (TFIL aka Testnet FIL).

We are live on Hyperspace Testnet -

Getting Started

Prerequisites

• Node.js
• Truffle

Installation

1. Clone the repository.
2. Install the dependencies with npm install.
3. Compile the contracts with truffle compile.
4. Deploy the contracts with truffle migrate.

Usage

To interact with the smart contracts, you can use the Truffle console or write scripts in JavaScript. Here's an example script that uses the CarbonRegistry contract:

TODO: Update code to use CO2.storage

const CarbonRegistry = artifacts.require("CarbonRegistry");

module.exports = async function(callback) {
  const registry = await CarbonRegistry.deployed();
  const mwh = 100;
  const sender = web3.eth.accounts[0];
  await registry.addProject(mwh, { from: sender });
  const projects = await registry.getProjects();
  console.log(projects);
  callback();
}

This script adds a project to the CarbonRegistry contract with a mwh value of 100, and then retrieves the list of projects.
