# Get testnet ETH

Arbitrum uses ETH to confirm transactions on the Arbitrum network. To get test tokens for the Arbitrum testnet, you first need to [use a faucet to obtain Ethereum Rinkeby testnet ETH](https://faucet.rinkeby.io). Then you can migrate those tokens to the Arbitrum Testnet using the [Arbitrum bridge](https://bridge.arbitrum.io).

Refer to the Arbitrum documentation for [instructions to bridge testnet ETH onto Arbitrum](https://developer.offchainlabs.com/docs/public_testnet).
