How to use OpenZepplin AccessControl Smart contract | Solidity for beginners | Day 11

This video is part of the series 30 Smart contracts in 30 days
https://docs.openzeppelin.com/contracts/5.x/

In this video, we explore how to use OpenZepplin AccessControl smart contract to define roles and grant access to different functions based on those roles.

Highlights
👩‍🏫 Define roles for different users in OpenZepplin AccessControl smart contract.
📝 Functions have a require statement to check if a user has the matching role.
🚀 Demonstration of creating roles for students and professors.
🤖 Set the default role for the contract admin in the constructor.
✅ Grant roles to different addresses using GrantRole function.
📝 Access different functions based on the assigned roles.
🧪 Test the contract by trying to grade a test and submitting a test.
Key Insights
👩‍🏫 Defining roles using OpenZepplin AccessControl smart contract allows for granular control over function access based on user roles.
📝 The require statement helps enforce role-based access control by ensuring that only users with the correct role can execute specific functions.
🚀 Creating roles for students and professors demonstrates how different roles can be assigned different functions.
🤖 The default role for the contract admin can be set in the constructor, giving the deployer admin privileges.
✅ Granting roles to different addresses allows for flexible assignment of roles to users.
📝 Accessing different functions based on assigned roles ensures that only authorized users can perform specific actions.
🧪 Testing the contract by attempting to grade a test and submit a test validates the role-based access control mechanism.
