Setup

1. Clone Repository

   $ git clone https://github.com/DemocracyEarth/ubi.git
   $ cd ubi

2. Install Dependencies

   $ npm install

3. Run Tests

   $ npx hardhat test

   To compute their code coverage run npx hardhat coverage.

Deploy

1. On hardhat.config.js configure the following constants for the kovan testnet:

   INFURA_API_KEY
   KOVAN_PRIVATE_KEY
   

2. Deploy on Ethereum kovan testnet:

   $ npx hardhat run scripts/deploy.js --network kovan

3. Interact with the console:

   $ npx hardhat console --network kovan

   Initalize the token with:

    const UBI = await ethers.getContractFactory("UBI")
    const ubi = await UBI.attach('0xDdAdE19B13833d1bF52c1fe1352d41A8DD9fE8C9') // Replace with your token address

Upgrade

1. Deploy new contract in a fresh address:

   $ npx hardhat run scripts/prepare.js --network kovan

2. Upgrade the proxy contract with the freshly deployed address:

   $ npx hardhat run scripts/upgrade.js --network kovan

Verify

1. On hardhat.config.js configure your Etherscan API key:

   ETHERSCAN_API_KEY
