Getting ETH on Arbitrum Testnet
To confirm any transaction on Arbitrum Testnet you need to own ETH tokens. ETH is the native coin for the Ethereum ecosystem. To get some test tokens for the Arbitrum Testnet, you first need to get tokens for the Ethereum Rinkeby testnet. Then you can migrate those tokens to the Arbitrum Testnet through a bridge.
To get Ethereum Rinkeby ETH tokens you can use the authenticated faucet at https://faucet.rinkeby.io/. This faucet requires you to write a public post on a social network profile you own. The content of the post must be the Wallet address you created in the How to install Metamask section. Just click on the account name and it will copy the address for you:

Then click on the dropdown menu that says Give me Ether and select the amount you want (the more you request the more time you have to wait until you can request again):
