Overview/Description

Discover transformative Blockchain technology with the Ethereum network using some of the UI (user interface)-based clients of MetaMask and Ethereum Wallet. For this course, participants are assumed to have a fundamental understanding of Ethereum and the workings of Ethereum clients. This course covers how to install the official Ethereum Wallet application, describe the UI options available, and use the MetaMask client to transfer ether from your account in MetaMask to the one in Ethereum Wallet. Ethereum Wallet not only works as a wallet, but also provides an interface for you to deploy your own smart contracts to Ethereum networks. It includes an interface to read data from contracts, and then write to them by invoking transactions. Learn to code a simple smart contract and deploy it to the Rinkeby network using the Ethereum Wallet UI. Upon finishing this course, you will have the skills required to work with the Ethereum network for transferring Ether to an account using MetaMask. And you will also know how to interact with smart contracts using Ethereum Wallet.
