At the end of the lesson we were given two challenges to complete on our own to further reinforce our understanding. Allow your smart contract to update the withdrawal address. Allow your smart contract to buyLargeCoffee for 0.003 ETH, and create a button on the frontend website that shows a…

In Part 1 of the project, we developed a Solidity contract that allows anyone to tip us ETH. In addition, they can also share their name and a message that will be stored on chain. Then we developed a JavaScript routine to deploy the contract to a local blockchain to…

For the second week of Road to Web 3, we were challenged to develop a “Buy me a coffee” web application. This is an app that will allow any wallet to tip me ETH (AKA Buy me a coffee) by interacting with a contract deployed to the blockchain. For this…

To continue my learning journey, I have decided to join Alchemy University. The first course I selected is titled Road to Web 3. My goal is to understand more about how to develop web3 applications, and more specifically to gain more understanding about developing various types of Ethereum contracts. For…
