We will start building a web application, using React and Typescript, that can interact with the multi-sig wallet smart contract written in Solidity. In this video I will show you a demo of the app and then explain how the code is organized.

In this video I will explain what a mutli-sig wallet is and show you how to write one in Solidity. Some features will be left as an exercise for you to complete.
