TL;DR: In the rapidly evolving world of blockchain technology, Ethereum has emerged as one of the most widely adopted platforms, enabling decentralized applications (dApps), smart
In the Ethernaut level 17 challenge, participants are tasked with finding and recovering Ether from a lost contract. The goal is to understand how contract
TL;DR: Challenge 13: Gatekeeper One, also known as Ethernaut Level 13, stands out because it necessitates a thorough understanding of Ethereum transactions and gas mechanics.
Welcome to the fascinating world of smart contracts, where lines of code dictate financial agreements and automate complex processes. But what about time? How do
Delegatecall is a powerful but intricate feature in Solidity that allows contracts to delegate execution to other contracts. Understanding delegatecalls is crucial for building advanced
Ethernaut challenges, akin to a hacking Capture The Flag (CTF) for Web3 enthusiasts, provide an immersive platform to explore Ethereum and Solidity programming. Each challenge
TL;DR Solidity contracts interact with other contracts using high-level calls (via interfaces) or low-level calls (call, delegatecall, staticcall). Key Differences: Best Practices: In Solidity, contracts
Imagine you walk into a fancy restaurant, eager to try their new menu. But before you can even glance at the dishes, the waiter informs
TL;DR: Web3.js is a powerful library that unlocks the potential of interacting with the Ethereum blockchain and other Web3-compliant platforms. One of its core functionalities
Imagine a world full of bugs and weird happenings, but we’re not talking about bugs you find under a rock—we’re diving into the cool world
This Web3/Solidity-based wargame is akin to a hacking Capture The Flag (CTF) challenge, where each level presents a smart contract puzzle waiting to be ‘hacked’.
Ever found yourself staring at your computer screen, wondering if Solidity has a personal vendetta against you? You’re not alone. Picture this: It’s 2 AM,
Solidity, the language powering Ethereum smart contracts, offers immense potential for building decentralized applications (dApps). However, the unique blockchain environment demands a different approach to
Have you ever wondered how innovative applications securely interact with the Ethereum blockchain? At the heart of this interaction are powerful tools known as Web3.js
TL;DR Debugging Solidity smart contracts is crucial due to their immutable nature. Hardhat offers a console.log function, similar to JavaScript’s, allowing developers to print variables
TL;DR Have you ever faced a sudden stop sign while navigating the Ethereum universe? Meet the execution reverted errors, the EVM’s way of keeping things
TL;DR Solidity is the main programming language for creating smart contracts on the Ethereum blockchain. This article covers beginner-friendly Solidity projects like the “Hello, World!”
