Once you've created a project in your DappHero admin, you can add a smart contract by clicking on the "Contract" button on the lefthand menu.
To add a new contract, you will need to know a few things first:
Address - (The location on the blockchain where the contract lives)
Network - (The specific blockchain network where the contract live)
ABI - (This is a special code object, called JSON, which tells DappHero how the contract works)
The Contract Name is also required, but this value can be anything you like.
