You learned how to write your own digital contract in Solidity. You developed and tested the contract interface in the Remix IDE. For further multi-user testing, you deployed this contract on Ganache Blockchain. On Ganache, you created two user accounts. The first account was used for publishing the contract. The second account was used for…

In this chapter, we will learn the creation of contract users on Ethereum. To create a user for our published contract, we will create another MyEtherWallet client attached to the same Ganache Blockchain that you have been using in the previous steps. Go to the MyEtherWallet screen and create a new wallet. Click on the contracts menu and select the “Interact with…

Now, you are ready to interact with the contract that you have deployed. Go back to MyEtherWallet desktop and click on the “Interact with Contract” tab as shown in the screenshot below − Paste the contract address that you previously copied in the “Contract Address” field. You also need to paste the “ABI / JSON Interface” of the contract…

To deploy the contract, select the Contracts menu option as shown in the screenshot below − You will need to enter the contract’s bytecode on this screen. Remember, when you compile your Solidity contract code, it generated a bytecode that runs on EVM. You will now need to obtain this bytecode from Remix IDE. Go to the Remix…

You have now created a wallet; this wallet is a client interface to the Blockchain. We will attach the wallet to the Ganache Blockchain that you have started in the earlier lesson. To do so, click on the Network dropdown box as shown in the screenshot below − Go to the bottom of the list. You will…

In this chapter, we will learn how to create Ethereum wallet. To create a new wallet, enter a password of your choice and then click on the “Create New Wallet” button. When you do so, a Wallet would be created. A digital wallet is essentially the generation of a public/private key pair that you need…

For client application, you will use MyEtherWallet. Download MyEtherWallet software from the following URL − If required, unzip the downloaded file and open index.html. You will see the following interface for creating a new wallet.

We will now briefly understand what is available on the Ganache desktop. On the Desktop, at the top we have several menu options out of which a few are of immediate relevance to us. The menu bar is highlighted in the screenshot below − Clicking on the TRANSACTIONS menu shows all the transactions performed so far. You…

Click on the settings icon at the top right hand side of the screen as shown in the screenshot below − The server settings screen will appear as shown below − Here, you will be able to set the values of server address and the port number for your Ganache server. For the time being,…

Ganache is used for setting up a personal Ethereum Blockchain for testing your Solidity contracts. It provides more features when compared to Remix. You will learn about the features when you work out with Ganache. Before you begin using Ganache, you must first download and install the Blockchain on your local machine. Downloading Ganache You…
