This will explain how to use storage, memory and calldata. Find out what the hidden facts are and how to master data locations in Solidity.
The end goal of an Ethereum project is to end up on the Mainnet, right? But we need a way to see how it would behave in that crazy jungle BEFORE deploying it. Let’s learn how to test our smart contracts on the Mainnet.
Nobody wants to waste gas on redeployments or a project directory packed with copy-pasted code. What if that code itself depends on another code and so on?
Depending on your application, Truffle migrations can become quite complex and confusing. The difficult part is to understand how to migrate interdependent contracts with arguments & libraries and how to handle the deployment aftermath.
Stop getting confused about when to use .call() and when not. Sometimes this suffix is required when calling functions, sometimes it is optional. When using Truffle, you might notice that there is a difference between calling your contract’s functions by adding and omitting the suffix .call(). This post will go through some of the various…
This post will teach you how to work with Truffle and Ganache. It is a simple guide on how to start mastering these two very useful tools. In this tutorial, for demonstration purposes, we will work on a simple Hello World smart contract. Following each step will help you understand how to start developing and…
This post will guide you through the initial steps in building your first decentralised application (Dapp) using Smart Contracts. I chose the Ethereum network and the Solidity programming language as they are the most widely used and they already have a few great tools that support the development process. Nonetheless, the most basic option for…
