Property-based testing is a powerful technique that can help developers find bugs in their code by generating and testing a large number of test cases based on properties that the code should satisfy. In this post, we will explore how to use property-based testing in Solidity, how to define properties…

First of all, it’s because it Encourages collaboration Muphry’s Law implies that we are all fallible and that mistakes can happen to anyone — and even more tragic — that mistakes will happen for sure :) Muphry’s Law implies that not only the mistakes inevitable, but they are also unpredictable…

Smart contracts revolutionized the blockchain ecosystem by enabling a wide range of decentralized applications (dApps) for various purposes. However, their complexity and the need for skilled developers and auditors hinder the mass adoption. This article explores the concept of universal and reusable smart contracts using a Diamond Management System, and…

As smart contracts become more complex, developers often need to optimize their code for efficiency, performance, and size. Solidity Assembly comes to the rescue in such cases, allowing developers to write lower-level code directly. Understanding Solidity Assembly Solidity Assembly, also known as “inline assembly”, is a low-level language that allows…

Welcome to another article on Solidity’s payable and non-payable functions! If you’re interested in blockchain development and smart contracts, you’ve probably come across these terms before. In this article, we’ll explain what payable and non-payable functions are, how they work in Solidity, and why payable functions are less costly (in…

TL;DR: Smart contracts are critical components of the blockchain ecosystem, and ensuring their security is vital. This article presents several security patterns that developers can employ to minimize vulnerabilities and risks in their smart contracts, ultimately contributing to a more secure, transparent, and efficient decentralized landscape. Why do we care? As the adoption of…

The ERC-XYZ standard introduces a comprehensive framework for creating and managing NFTs that addresses critical challenges faced by the industry, including gas fee optimization, royalty redistribution, and enhanced security. This paper outlines the innovative features of ERC-XYZ, highlighting its potential to revolutionize the NFT landscape and foster a more sustainable, equitable, and secure ecosystem.

How to safely implement the ‘delegatecall’ Solidity function, which was part of some of the biggest hacks in the crypto industry! Introduction delegatecall is a powerful and important feature in Solidity that allows a contract to delegate a function call to another contract. It enables the separation of contract logic and…

The reentrancy vulnerability is one of most serious ones that can be found in solidity smart contracts. Apart from the “classic” reentrancy like the one from the infamous DAO hack, there are other types of this vulnerability. In this article, we describe them along with some popular strategies on how…
