Counter Smart contract

Building & deploying a smart contract on KITE AI with Remix

Please follow the below steps to build your smart contract on Kite AI:

Step 1: Open Remix IDE

• Navigate to Remix IDE in your browser.

• Once loaded, you’ll see the file explorer on the left-hand side where you can manage your Solidity files.

Step 2: Create a New File

• In the Remix file explorer, click the ”+” icon to create a new file.

• Name your file counter.sol

Step 3: Write the Solidity Code

Copy and paste the following Solidity code into your Counter.sol file:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;

contract Counter {
    uint256 public count;

    function increment() public {
        count += 1;
    }

    function decrement() public {
        require(count > 0, "Counter cannot be negative");
        count -= 1;
    }

    function getCount() public view returns (uint256) {
        return count;
    }
}

This smart contract does the following:

• Stores a counter: The count variable holds the current value.

• Provides a getter: Although count is a public variable, the getCount() function is an example of how you can explicitly return data.

• Allows incrementing: The increment() function increases the counter.

• Allows decrementing: The decrement() function decreases the counter.

Step 4: Compile the Contract

• On the left sidebar, click the “Solidity Compiler” tab (the one with the “S” icon).

• Ensure the compiler version is set to ^0.8.20 version.

• Click “Compile Counter.sol”.

• Check the code for typos or version mismatches, if you encounter any errors.

Step 5: Deploy the Contract

• Switch to the “Deploy & Run Transactions” tab (the Ethereum icon on the left sidebar).

• Under “Environment”, select “Injected Metamask or WalletConnect”. This will connect Remix to your MetaMask (make sure MetaMask is set to the Kite AI Testnet).

• Verify that your account is correctly connected.

• In the “Contract” dropdown, select Counter.

• Click the “Deploy” button.

• Confirm the deployment transaction in MetaMask.

• Once deployed, your contract will appear under “Deployed Contracts”.

Step 6: Interact with Your Contract

• Expand your deployed Counter contract in Remix.

• You can call the getCount() function to check the current counter value.

• Click the “increment” button to call the increment() function and “decrement” button to call the decrement() function. Confirm the transaction in MetaMask.

• After the transaction is confirmed, call getCount() again to see the updated counter value.
