If you want to interact with an Ethereum-based network that supports Ocean Protocol, then you'll eventually need Ether or [Ocean Tokens](/concepts/ocean-tokens/) _for that network_. (Every Ethereum-based network has its own Ether and maybe its own Ocean Tokens, and you can't use those in other networks.)
At the time of writing, there were some public testnets you could use to test an Ocean Protocol application. For more information about those, see the page about [testnets](/concepts/testnets/).
You will need a [wallet that can hold Ether (for any Ethereum network) and Ocean Tokens (for any Ethereum network)](/concepts/wallets/). For the purpose of this tutorial, you can use MetaMask. See [our tutorial about how to set up MetaMask](/tutorials/metamask-setup/).
You can get Kovan Ether (KEth), for the Kovan Testnet, from a Kovan faucet: see [the official list of Kovan faucets](https://github.com/kovan-testnet/faucet). You have to give the faucet your Kovan address (wallet account address). You can get that from MetaMask. It's a string that looks like:
The Nile faucet has a limit of one request every 24 hours for the same Ethereum address. But don't worry, the Ether given is more than enough for interacting with the network.
If you're running a local Ganache-based testnet, then it creates several accounts at network launch time, and gives each of them some Ether. The addresses and private keys of those accounts should be shared (to logs or the console) during the launch process. You can use those accounts and their Ether.
**Option 1:** If you're running a local Spree testnet, then you can send some Spree Ether to `<YOUR ADDRESS>` using the following command (a long command that wraps around):
That command uses [Ethereum's JSON RPC API](https://wiki.parity.io/JSONRPC.html). You can also create a new account using the Parity Ethereum CLI. See [the Parity Ethereum CLI documentation](https://wiki.parity.io/CLI-Sub-commands).
**Option 2:** By default, the Spree testnet is configured to bootstrap ten accounts with a decent amount of Spree Ether in each one. To get access to those accounts, you can import the following seed phrase into MetaMask (e.g. by logging out and then clicking "Import using account seed phrase"):
Details about the bootstrapped accounts can be found in [the README.md file in the Barge repository](https://github.com/oceanprotocol/barge/#spree-network). They're the ones of type "mnemonic."
**Option 3:** Another option is to run [the Ocean faucet server](https://github.com/oceanprotocol/faucet) on your machine, with default configuration settings. The default settings enable it to dispense Spree Ether. To ask the faucet to send some Spree Ether to `<YOUR ADDRESS>`, use the command (a long command that wraps around):
In the future, it will become possible to earn Mainnet Ocean Tokens as network rewards. The [Ocean Protocol Technical Whitepaper](https://oceanprotocol.com/tech-whitepaper.pdf) explains that in more detail.
All Squid libraries have methods to request Ocean Tokens. They work by calling the "Dispenser" keeper contract, a contract which is only deployed to testnets. Therefore they will only work in testnets. They're documented in the following places:
- [the `squid_py.ocean.ocean_tokens` module](https://squid-py.readthedocs.io/en/develop/api/squid_py.ocean.ocean_tokens.html): see the `request()` method.
- [the `squid_py.ocean.ocean_accounts` module](https://squid-py.readthedocs.io/en/develop/api/squid_py.ocean.ocean_accounts.html): see the `request_tokens()` method.
- [The squid-java docs](https://www.javadoc.io/doc/com.oceanprotocol/squid/): click "All Classes" then "AccountsManager" then scroll to the bottom of the Class AccountsManager page where you'll find the `requestTokens()` method.
The [Example Code page](/tutorials/example-code/) has links to example Squid code (in all of the languages), including examples of using the above methods.
