# Ethereum Remix

Go to <https://remix.ethereum.org/>

### Writing your smart contract

![1. Create a "New File" under contracts with name Counter.sol](https://3781397247-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LlEOlYqEG_GKuO5Rehq%2F-Mc1gG1tENE5fc-s9JoF%2F-Mc1lM9pFoGLpbgiCUbQ%2FScreen%20Shot%202021-06-12%20at%205.24.11%20PM.png?alt=media\&token=20e1826f-822c-440c-8b80-be3257b15d56)

Copy and paste the code below to Counter.sol file

```
pragma solidity >=0.4.22 <0.8.0;

contract Counter {
    uint256 private count = 0;
    uint256 moneyStored = 0;

    function incrementCounter() public {
        count += 1;
    }
    function decrementCounter() public {
        count -= 1;
    }

    function addMoney() payable public {
        moneyStored += msg.value;
    }

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

    function getMoneyStored() public view returns (uint256){
        return moneyStored;
    }
}
```

### Compiling

![2. Compile Counter.sol](https://3781397247-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LlEOlYqEG_GKuO5Rehq%2F-Mc1gG1tENE5fc-s9JoF%2F-Mc1monqfFbvnrJZ0gZn%2Fcompile.png?alt=media\&token=445f5cfd-a55d-4b80-9d15-e8d0d4eab636)

### Deploying

If you want to deploy the contract to a live network like Harmony Testnet or Mainnet, configure your metamask by adding the required Harmony networks using this [guide](https://docs.harmony.one/home/network/wallets/browser-extensions-wallets/metamask-wallet).

![3. Deploy the compiler contract. Select Injected Web3 for deploying to live network like Harmony testnet.](https://3781397247-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LlEOlYqEG_GKuO5Rehq%2F-Mc1gG1tENE5fc-s9JoF%2F-Mc1mxYZoFl0RYzg_ZZm%2Fdeploy.png?alt=media\&token=12838c6a-f655-4dc8-8979-17c0c0c2bc4d)

![4. Confirm the deploy transaction in metamask and you can find the deployed contract address.](https://3781397247-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LlEOlYqEG_GKuO5Rehq%2F-Mc1gG1tENE5fc-s9JoF%2F-Mc1nOKB3yOwJ_dCktu9%2Fdeployed.png?alt=media\&token=3c9846a8-0c08-4197-883e-4150478c7f0b)
