We've learned how to deploy a simple script to our local PiVM. Now, let's learn how to deploy it to a different network. We can deploy this script to our anvil network. You know, our locally running anvil network. First, open a new terminal, clear it out, and run anvil: ```bash anvil ``` We can then run our script like this: ```bash mox run deploy ``` Our script will run, but nothing will happen on Anvil. This is because we're deploying to Anvil, and our current setup is running on PiVM. We're going to use a flag to tell our script which network we're deploying to. If we run: ```bash mox run --help ``` We'll see a number of commands to help us interact with our Anvil chain. There's a flag called `--network` which lets us define the network we want to deploy to, taken from our `mocassin.toml` file. To see what's in our `mocassin.toml` file, let's look at it! This `mocassin.toml` file is used to configure all of our networks and contains any kind of setting for Moccasin. You can see all the possible settings in the TOML documentation here: https://cyfrin.github.io/mocassin/all_mocassin_toml_parameters.html In our case, we can create a new network object named anvil. To do this, we'll make a new section in our `mocassin.toml` file: ```toml [networks.anvil] ``` We need to give our network a URL. We can find the Anvil URL running in the terminal: ```toml url = "http://127.0.0.1:8545" ``` We'll also add this flag: ```toml save_to_db = false ``` We've added our new network section to our `mocassin.toml` file. Let's try to deploy our contract again! ```bash mox run deploy --network anvil ``` Our script will run, but it'll ask us to hit yes. We'll see a value error here. ```bash ValueError: <boa.network.NetworkEnv object at 0x1113838c0> eoa not defined! ``` This is a common error. You can find more information about this in the Moccasin documentation: https://cyfrin.github.io/mocassin/common_errors.html It means that we're trying to deploy to Anvil, but we haven't added an account to our `mocassin.toml` file! We can do this by following the wallet guide in the documentation: https://cyfrin.github.io/mocassin/core/concepts/wallet.html Our Anvil network is running, so we can go there and grab a private key to deploy our contract. We can then run our deploy script like this: ```bash mox run deploy --network anvil --private-key 0x9740....2f764180aa3 ``` That was an example of how to deploy a script to a different network. In the next section, we'll learn how to use Moccasin's wallet commands!
