Types are among the most important building blocks of a statically-typed programming language, and since Solidity falls into that category, we finally have the opportunity to entertain ourselves with this crucial topic. By learning about types, we’ll get more closely familiar with the Solidity features that are based on idiosyncrasies of a particular data type. … Read more
In this article, we’ll take a detailed look at the structure of a smart contract (docs). 💡 We’ll learn about state variables, functions, function modifiers, events, errors, struct types, and enum types. We have recognized most of these elements in action in the previous articles, especially in the ones where we had real examples of … Read more
There are four major ways to install the Solidity compiler: Install Solidity Compiler via npm Install Solidity Compiler via Docker on Ubuntu Install Solidity Compiler via Source Code Compilation Install Solidity Compiler via Static Binary and Linux Packages In this tutorial, we’ll have a quick look at each of them and give you a link … Read more
Following up on the last article, we will take a closer look at other types of pragmas, but also check out how we can import other source files and paths (docs). After that, we’ll take a break by going through a small section on comments and getting to know them better. It’ll probably be very … Read more
In the previous articles, we looked at some of the representative examples of smart contracts representing possible real-world scenarios. Our main focus was on capturing the essence of each case, without particular attention given to the general structure, i.e. layout of the respective source files. However, in this mini-series starting with this article, we will … Read more
This article continues on the Solidity Smart Contract Examples series and implements an example of a modular contract checking that the balances being sent between the addresses comply with the requirements (docs). We’ll first lay out the entire smart contract example without the comments for readability and development purposes. Then we’ll dissect it part by … Read more
This article continues on the Solidity Smart Contract Examples series, which implements a simple, but the useful process of safe remote purchase. Here, we’re walking through an example of a blind auction (docs). We’ll first lay out the entire smart contract example without the comments for readability and development purposes. Then we’ll dissect it part … Read more

This article continues on the Solidity Smart Contract Examples series, which implements a somewhat more complex process of a blind auction. 🌍 Recommended Tutorial: Smart Contracts with Solidity – Crash Course Here, we’re walking through an example of a blind auction (original source). We’ll first lay out the entire smart contract example without the comments … Read more
With this article, we are starting a journey of going through smart contract examples in Solidity. We’ll first lay out the entire smart contract example without the comments for readability purposes. Then we’ll dissect it part by part, analyze it and explain it. Following this path, we’ll get a hands-on experience with smart contracts, as … Read more
In this final, concluding part on installing the Solidity compiler, we’ll be going through two more approaches, the static binary / precompiled Solidity Compiler installation, and Linux packages installation. We will follow the outlined steps for these two fairly simple and quick approaches, and after that, make an overview of all the approaches we made … Read more
