Kite ChainDeveloping Smart Contracts
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.
