# Counter Contract - Remix

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

**Step 1: Open** [Remix IDE](https://remix.ethereum.org/)

* 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.
