In this tutorial we will build on our previous tutorial in which we created a todo list smart contract. Our goal is to build a front end that can be deployed to a web server to allow users to interact with our smart contract through a GUI.

This is part 3 of a 4 part series on how to develop smart contracts on the Koinos blockchain.

• Part 1 on setting up the dev environment can be found here.
• Part 2 on building the smart contract can be found here.

We will use HTML, CSS and vanilla JS but you can use Vue, React, Svelte etc. It’s also possible to connect to the smart contract using Swift or Kotlin on mobile. In this tutorial we are using the Kondor wallet Chrome extension, we can also use WalletConnect but that is out of the scope of this exercise. We will need a test account in Kondor with some tKoin.
