The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - Global Variables in Solidity I

The video tutorial introduces global variables in Solidity, focusing on their role and examples like msg.sender and msg.value. It explains how these variables provide blockchain information and are accessible throughout a contract. The tutorial includes a practical example of creating a Ledger Balance contract using these variables. It concludes with an exercise to create a new contract that inherits from the Ledger Balance contract, reinforcing the concepts learned.
