Okay, let me show another screenshot.


If you are trying to find RPC url of ropsten testnet, click the network name and simply copy the RPC url

That's all. Hope this is helpful for you. Thanks.

Thank you! It has been a while since this post but I just wanted to thank you, this solved my problem when deploying it to a testnet (Rynkeby in my case!)

You should pass your wallet private key from .env file to the account property.

    ropsten: {
      url: `https://ropsten.infura.io/v3/${process.env.infuraId}`,
      accounts: [process.env.privateKey]
    },
