Create and deploy contracts (untyped) Calls, transactions, events, filters and topics (untyped) This will take you through the steps of connecting to Infura and retrieving the balance of an account from the mainnet (the public Ethereum chain). Infura provides a set of public nodes removing the need to have a local or maintained client fully synchronized with the main Ethereum network. Note. Deploy a specific contract, specified by the contract object, with optional constructor arguments. This is useful for singleton contracts, such that only one instance of this contract exists for your dapp. This will set the address of the contract after deployment (i.e., Contract.address will equal the newly deployed address), and it will. Contract Deployment. As you're aware by now, deploying contracts and testing them costs Ether. We have plenty of that available to us on our local Ganache-cli instance, albeit simulated and only usable locally. But on the Ethereum mainnet, we need actual cryptocurrency to deploy. Fortunately, before we have to make that plunge, there are the testnets. And with them, faucets. Pick a Testnet.
