Ok, so I know what the custody address is, but I'm not sure how Moxie is ending up in it. 

What other mechanic am I missing here that's sending Moxie to my FC custody address?

Technically each Fan Token has to have a unique wallet address associated, in your case we used the connected address for your personal Fan Tokens, and your custody address for /success, so the Moxie you see there is collected from the Fan Token sale fees. That wallet also holds the Fan Tokens (5% auction fee). You can import the custody wallet to any other wallet - on Warpcast app (mobile) go to settings and you can get your seed phrase -> import to Coinbase Wallet, or Metamask. I need to write a guide on how to do it next week :)

Awesome, thanks so much! I think that covers all of the potential mechanics that could confuse me, but who knows! I appreciate you guys always coming to answer. :) 

I'm familiar with how to access funds in the custody address, but that is a good idea for content - you're right. I can write that guide if ya want!

It's ok, I think I need to write it in the official docs so I could reference it later 👍 we always try to use the connected wallet but in some cases we have to go with the custodial.
