Yayy! We've launched on Product Hunt TODAY. Please support our launch here 😉! 
Detecting whether an Ethereum address belongs to an ERC20 token contract requires a bit of investigation, as there’s no single foolproof method. Here’s a breakdown… Read More »Detect if an Ethereum Address Is an ERC20 Contract
Sure, I’d be happy to guide you through receiving a value returned by a Solidity smart contract transacting function. This process involves interacting with the… Read More »How To Receive a Value Returned by Solidity Transacting Function?
To receive and send USDT (Tether) in a smart contract written in Solidity, we need to integrate the ERC-20 standard functionalities into our contract. USDT… Read More »How To Receive and Send USDT in Solidity?
In Solidity, bytes32 and string are two different data types, each serving distinct purposes. Let’s delve into what they represent and how they can be… Read More »Representing bytes32 as String in Solidity
Imagine you’re building a high-security vault in the digital world of Solidity smart contracts. You want to ensure only authorized users can access certain functions… Read More »What Are Modifiers?
The world of decentralized finance (DeFi) is built on smart contracts – the self-executing code that powers applications and transactions on the blockchain. But just… Read More »What Are Most Common Vulnerabilities in Smart Contracts?
Function modifiers Function modifiers in Solidity are powerful tools for adding common functionality to multiple functions within a contract. They allow developers to enforce security… Read More »Function Modifiers (view, pure, payable) and Fallback Functions in Solidity
In the realm of Ethereum smart contracts, understanding account ownership is akin to mastering the foundation upon which secure and robust decentralized applications (DApps) are… Read More »Understanding Account Ownership in Solidity: A Comprehensive Guide
In Solidity, visibility and inheritance are pivotal concepts governing the accessibility and reusability of functions and variables within contracts. Understanding these concepts is essential for… Read More »Understanding Visibility and Inheritance in Solidity
Integer overflow and underflow are common issues in programming, including Solidity, the language used for developing smart contracts on the Ethereum blockchain. These issues arise… Read More »Integer overflow and underflow in solidity
