• Interact with your contract:

Example Contract:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract MessageStore {
    string public message;

    function setMessage(string memory newMessage) public {
        message = newMessage;
    }

    function getMessage() public view returns (string memory) {
        return message;
    }
}

• Set a Value: Use the set function to store a number in the contract.
• Get the Value: Use the get function to retrieve the stored number.

You’ll notice that calling the set function will require gas (a small amount of Ether) to execute, whereas calling the get function is free as it’s a view function.
