Welcome to the course on how to build a decentralized application on blockchain. By the end of this course you will learn how to create an application that interacts with the Ethereum Blockchain. In Part 1 we will show you how to integrate your wallet with Portis API, view your balance, view the balances of other addresses, and add test Ethereum using a faucet. In Part 2 we are going to implement and deploy smart contracts and transfer the funds using your new app. Follow along and you can call yourself a blockchain developer!
