It's been fun showing you how to code your first smart contract in solidity, hopefully, you’ve gained some understanding of how to write smart contracts. If you want some private tutoring time with me, kindlyc
In Solidity, it is possible to cast an address into any arbitrarily-typed contract variable, even if the contract housed at that address is not of the same type as the one being casted. Malicious actors can exploit this to conceal harmful code. Let’s see how. pragma solidity 0.8.4; imp...
Discover how Solidity can make it easy to program smart contracts for the Ethereum blockchain platform.Learning objectives In this module, you will learn how to: Explain what Solidity is and how the features of the language work. Understand the components of a smart contract. Create a basic ...
How to code smart contracts using Solidity with real-world supply chain examples. The history of cryptography and how it’s essential for securing digital communication and data. The fundamentals of encryption, how data is represented in binary, and its application to modern cryptographic me...

They enable us to read and write data to the blockchain, as well as execute code. Smart contacts are written in a programming language called Solidity, which looks a lot like Javascript. It is a full blown programming language that will allow us to do many of the same types of things ...

Solidity and freedom are the foundation of happiness. If you’re not solid, if you’re not free, happiness isn’t possible. So every step is to cultivate more solidity and freedom. As you walk, you can say to yourself, “I am solid. I am free.” This is not autosuggestion or ...
The primary language used is Solidity for smart contracts, while the front end can be developed using JavaScript frameworks like React or Vue.js. How much does it cost to build a DApp on Polygon? Costs vary widely based on complexity, features, and development time, but overall expenses are...
delving into advanced scenarios, modifiers prove to be a versatile asset for developers. As you integrate these concepts into your projects, prioritize simplicity, clear naming, and logical organization for code that not only works but is also easily understood. Happy coding on your Solidi...
