If you want to build a blockchain app, one of the most important things to know is how to write a smart contract.

In this Tech Tuesday, Anastasia Lalamentik, Full Stack Engineer at Kaleido, walks through how Ethereum smart contracts work and go over related concepts like gas fees, the Ethereum Virtual Machine (EVM), the block explorer, and the Solidity programming language. 

Before watching the webinar, there’s some optional prep work you can complete if you'd like to follow along with Anastasia's demonstration, linked here (though it's fine to just listen in too!)

This checklist will walk you through:

• Setting up a Node development environment on your machine
• Installing Hardhat
• Installing Metamask
• Using a Goerli Faucet to request funds
• Setting up a Goerli Network endpoint

By the end of this one hour webinar, attendees will know how to:

• Write a simple smart contract 
• Deploy their smart contract to an Ethereum test network through tools like Hardhat and the MetaMask wallet
• Test interactions with their deployed smart contract and ensure that everything is working properly
