So far we've built selling unruggable subnames, custom subname minting prices, reserving subnames, whitelisting options, token-gated community subnames, etc. You can check our work on our Goerli Dapp here: https://staging_app.namespace.ninja/.
Now, we are on a mission to allow anyone to become a Digital Identity Provider in less than 2 minutes, and start selling Subnames directly from their own Blog, Website, or Dapp.
You can check and test the Goerli Widget on our test Blog we launched: https://namespace-blog.000webhostapp.com/sample-page.
For setup and integration, you can ping me (@thecaphimself) on Twitter.
