To Note

• Before developing and testing the contracts, I have my blockchain network running in Ganache and MetaMask extension connected and pointing to Localhost:8545.

• In the Deploy tab in Remix IDE, I connected to my local Ganache chain by selecting Injected Web3 in the Environment column.

• For each contract, I filled in the constructor parameters before transacting and deploying.

ERC20 PupperCoin

I used a standard ERC20Mintable and ERC20Detailed contract for the PupperCoin.sol.

Crowdsale

This contract raises Ethereum by issuing PupperCoin. One token (TKN) equals 1 ETH in order to maintain parity with Ether units and can be divided into TKNbits as Ether can be divided into wei. The goal is to raise 300 ETH with this crowdsale.
