title: What happens when you 'create' an item on the OpenSea app?
body: <p>Very noobie here. I'm sorry,</p>
  <p>Does anybody know what happens on OpenSea when you actually CREATE an item?</p>
  <p>I know it doesn't mint one but what it does? (As it signs a transaction tho).</p>
  <p>I've been trying for weeks to understand the &quot;gasless&quot; proxy thing they have but I don't know how they actually transfer an NFT to your Wallet, even if it's not minted.</p>
  <p>I also managed to deploy and mint a Creature with the example contract (open sea creatures, <a href="https://github.com/ProjectOpenSea/opensea-creatures" rel="nofollow noreferrer">https://github.com/ProjectOpenSea/opensea-creatures</a>) but how can I let Users mint their own item on this factory contract?</p>
