This article is Part III of the “All About Errors” sub-series. After looking at the different type of errors (Compile vs Runtime Errors), the different type of Solidity errors and the distinctions between them, we will now look at the different ways to handle them. Solidity provides multiple built-in methods…

This article is Part II of the “All About Errors” sub-series. After looking at Compile Time errors in Part I (errors generated by the Solidity compiler), we will now look in Part II at runtime errors (errors generated at the time you interact with a contract deployed on a live…

This article is Part I of the “All About Errors” sub-series. We will now look in more details at a first broad category of errors in Solidity: errors related to the Solidity compiler, known as “Compile Time Errors” or “Compiler Errors”. As you will see, the Solidity compiler solc generates…

Today’s article starts a new sub-series within the All About Solidity article series, focused on errors in Solidity and EVM-based execution environments. In Smart Contract land, errors can be lethal. If not handled properly, they can cause bugs and vulnerabilities. …

Examining the available suffixes in Solidity when handling time in smart contracts — After covering how to deal with ether units in Solidity in “All About Ether Units,” we will now cover time units. This article will examine the available suffixes in Solidity when handling time in smart contracts. We will see that working with time units in Solidity has its pitfalls due…

Using different currency units available in Solidity when writing smart contracts — In this article, we will learn the basics of Ether Units in Solidity. We will look at how to specify ether denominations like wei , gwei and ether and the different options available for declaring values suffixed with one of these Ether denominations. Table of Contents Introduction to Ethers Currency Units Ethers…

Walk through the inner working of constant variables in Solidity — In this article, we will look at constant and immutable, their properties, visibilities, padding rules, the types allowed, and different ways of using them with examples from the LUKSO smart contracts in depth. Table of Contents Basics of Constant and Immutables How Constant and Immutables Are Placed in the Contract Bytecode? Padding Rules…

Understanding the structure and behaviour of a smart contract’s bytecode — Part 5 of the “All About Data Locations” subseries. This article focuses on the last data locations of the EVM that are accessible in Solidity: the bytecode of a smart contract. We will look at most aspects of a contract’s bytecode at the architecture level. This includes some detailed explanations…

Exploring the EVM stack machine, and how pushing and popping this in and out of the stack work. — This is Part IV of the “All About Data Locations” subseries. In today’s article, we will look at the fourth data location of the EVM: the stack. …
