Solidity powers Ethereum smart contracts, but writing effective code requires more than knowing the syntax. From managing gas costs and avoiding security vulnerabilities to applying proven design patterns and testing rigorously, this guide breaks down essential Solidity best practices to help you build secure, efficient, and production-ready smart contracts with confidence.
NFTs (Non-Fungible Tokens) have taken the digital world by storm, changing how we perceive ownership of art, music, gaming assets, and even real estate. But
Web3 promises a democratized financial landscape, but a shadow lurks within its decentralized exchanges (DEXes) – Frontrunning. This exploitative practice leverages knowledge of upcoming transactions
Immutability – the cornerstone of blockchain technology – guarantees that once data is written, it cannot be altered. This concept empowers transparency and trust, making
Solidity, the preeminent language for writing smart contracts on the Ethereum blockchain, is a powerful tool. But like any powerful tool, it has its quirks
Flash loans, a cornerstone of DeFi (Decentralized Finance), offer exciting liquidity possibilities. But in the wrong hands, they can become a developer’s nightmare – fueling
Ethernaut Level 15, “Naught Coin,” throws you headfirst into the world of ERC20 tokens and their potential vulnerabilities. This challenge presents a seemingly locked contract
TL;DR In the world of smart contracts, where code governs the execution of transactions and other functions, the importance of proper input validation cannot be
Access control is a crucial aspect of smart contract security, governing who is authorized to perform specific actions within the contract. Just as a bouncer
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
Blockchain technology is really innovative, and smart contracts are a big part of that. Smart contracts are like automatic agreements that run themselves, but they
The Ethernaut Level 3, called “Coin Flip,” is a lesson on the weak spots in how smart contracts handle chance and prediction. This article walks
Smart contracts, the self-executing code on blockchains, have revolutionized various industries. They offer trust, transparency, and automation in transactions, forming the backbone of Decentralized Applications
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’.
