Testnet environments

Testnet environments are public nevermined environments deployed on public EVM-compatible testnet networks. Typically we use Arbitrum Goerli. 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 Goerli testnet ETH. Then you can migrate those tokens to the Arbitrum Goerli Testnet using the Arbitrum bridge.

Network Fee

You need to pay a fee to use a Nevermined environment when a payment is being done through the Smart Contracts. This needs to be configured by the content publisher. You can find more information in the Network Fees section.
