Smart Contract Management and Frontend

Overview

This project includes a Solidity smart contract and a frontend interface for interacting with it.
The contract allows users to manage a message string, increment a counter, and transfer ownership securely.
The frontend provides a seamless UI for interacting with the deployed contract on the blockchain.

Features

• Set and Update Message: Users can modify the stored message.
• Counter Increment: Allows users to increase a counter value.
• Ownership Transfer: Restricts administrative actions to the owner and allows ownership transfer.
• Event Logging: Emits events for message updates, counter increments, and ownership changes.

Imports

• None: This contract does not rely on external libraries.

State Variables

• Counter: Initializes at 0.
• Ownership: The deployer of the contract is set as the owner.

Functions

• incrementCounter()

  • Increments the counter by 1.
  • Emits a CounterIncremented event.

• transferOwnership(address newOwner)

  • Allows the current owner to transfer ownership to another address.
  • Ensures the new owner is not the zero address.
