 ## Ethereum Testnets, Faucets and Deployment
 
-Deploying directly to **Mainnet** is not recommended and carries a large amount of associated risk. There are multiple public **Ethereum** **testnets**, each with a different deployment method and process. They are used to stage and test applications in a “live'' public environment prior to deploying a token or application to the **Ethereum** **mainnet**. **Ethereum** networks have two identifiers, a **network ID** and a **chain ID**. Although they often have the same value, they have different uses. Peer-to-peer communication between nodes uses the **network ID**, while the transaction signature process uses the **chain ID**.

 ### Testnet Comparison
 
-**Testnets** allow projects to be deployed in a public setting without incurring the costs and risks associated with deploying to the **Ethereum Mainnet**. Most **testnets** require that test **eth** is accessed from **faucets**. Using a **faucet** protects the **testnet** from spam attacks since the **eth** is controlled by trusted parties. This has become the primary way to acquire **eth** for a specific **testnet**. The community manages these public test networks for the benefit of developers and testing. Let’s take a look at the different [**Ethereum** **testnets**](https://ethereum.stackexchange.com/questions/27048/comparison-of-the-different-testnets) and associated properties.

 **Ropsten** has conditions as close as possible to **mainnet** and was historically the first major **testnet**. It has had some attacks and vulnerabilities which have been addressed (DDOS and 51% attack). **Kovan**, **Goerli** and **Rinkeby** are stable and have increased usage. Generally, prior to deploying to **mainnet**, it’s advised to deploy to and test on multiple **testnets**.

 If you have reviewed the previous blockchain modules in this series, you will already have a good understanding of **MetaMask** and how to use it. When deploying to either a **testnet** or **mainnet** , the metamask client provides a robust interface and wallet for connecting to and interacting with Ethereum blockchains. Be careful when using the Main Ethereum network, **mainnet**.
 
-Using **MetaMask** to send **Ether** and tokens on a **testnet** is straightforward. As we've seen in previous tutorials, the client provides an easy interface to select and use different Ethereum networks. For interacting with development networks, it's simple with **MetaMask** to connect to **Localhost 8545** or **Custom RPC** to connect with **ganache-cli** , **ganache app** and **truffle develop**. Similarly, MetaMask has predefined connections to the public testnets **Ropsten** , **Kovan** , **Rinkeby** and **Goerli**.
