The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - What Are Interfaces in Solidity

The video tutorial explains the concept of interfaces in programming, highlighting their similarities to abstract contracts. It covers the characteristics of interfaces, such as not having functions with implementations, constructors, or state variables. The tutorial emphasizes the value of interfaces in connecting information and avoiding code duplication. It demonstrates creating a basic contract and using interfaces to interact with it, showing how interfaces can connect multiple contracts without copying code. The tutorial concludes with a practical demonstration of interfaces in action.
