Ropsten address links?

[max-mapper]

Hi, I'm trying to test everything out on Ropsten but can't find the ropsten.etherscan.io links for the newer subdomain smart contracts. Thanks

I tried deploying this to ropsten and ran into this error:

$ truffle migrate --network ropsten

My truffle.js looks like this:

const HDWalletProvider = require("@truffle/hdwallet-provider");

const mnemonic = process.env.ROPSTEN_MNEMONIC;
const ROPSTEN_ID = process.env.ROPSTEN_ID;

module.exports = {
  networks: {
    ropsten: {
      provider: function() {
        return new HDWalletProvider(
          mnemonic,
          "https://ropsten.infura.io/v3/" + ROPSTEN_ID
        );
      },
      network_id: "3"
    }
  }
};

Any ideas? I tried on two machines (Mac and Linux) and got the same error. Also tried with truffle cli@master

After realizing there was an implicit dependency on ENSRegistry.sol I was able to deploy by using this migration

var ENS = artifacts.require("@ensdomains/ens/contracts/ENSRegistry.sol");
var SubdomainRegistrar = artifacts.require("SubdomainRegistrar");

module.exports = async function (deployer, network, accounts) {
    await deployer.deploy(ENS)
    const ens = await ENS.deployed();
    await deployer.deploy(SubdomainRegistrar, ens.address);
};
