How can we ensure our data is synchronized? To obtain data from contracts, we often make one Ethereum call after another. But this will not guaranteed that all your data is coming from the same block. But then, how do we call multiple functions simultaneously?
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.
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…
