Thanks for sharing this, but based on my understanding, sub account is still a new address and people have to create for every apps.

What's the benefits comparing the Warpcast wallet approach right now?

Building /recaster /modbot 
and @newcaster

Recaster

Thank you so much for detailed explanation!

I am build another Farcaster client /recaster and look for wallet solution for my app. The sub account is promising and I will try it!

The challenges I see with app accounts today 
1. Cold start: funded from scratch 
2. Address proliferation: hard to keep track of addresses created across apps 
3. Asset proliferation: bits of assets spread across all of these addresses 
4. Lock in: hard to use these assets on other apps, if the app shuts down you may lose access. 

Sub Accounts solve all of these 
(1.) and partially (3.), are solved by Spend Permissions, where users can allow an app account to use funds from the universal wallet, but do not need to move any funds up front 

(2.) through (4.) are solved by the fact that the universal wallet is now an owner of the app accounts, and can allow the user to see and manage all app accounts on a single interface.
