https://youtu.be/BOx167NBmew Smart Contract Testing Course - I just released a new course on Solidity smart contract testing on EatTheBlocks Pro. Uses the Test-Driven-Development (TDD) approach. Covers tests in Javascript & Solidity with Truffle  Ethereum 2.0: What you need to know - I wrote this piece on the future of Ethereum…

In the last part of this tutorial we finished all the functionalities of our smart contract. Unfortunately, we have a lot of code duplication in the update and delete function. We use the same for-loop to find a specific entry of our users array. In this video, we will extract…

We are going to continue our CRUD smart contract and finish the main features. You will learn: "Update" and "Destroy" in CRUD Delete an entry of a Solidity array

We will start a CRUD smart contract in Solidity. Crud stands for Create, Read, Update and Delete, and represent a very standard set of data operation that most application needs to do. Once you know these 4 operations, you are well-equipped to develop a large range of smart contracts. In…

In this video, we will build on the previous "Simple storage" smart contract, and store list of data instead of just a single piece of data. You will learn how to: Represent list of data with Solidity arrays Access a specify entry of array Get an array length

In this video, we are going to finish our simple storage smart contract, which can set and get the value of a variable. You will learn: Difference between transaction and calls How to specific calls in Solidity with view / pure keyword Getter functions automatically created by Solidity How the…
