In this tutorial, we walk you through building an indexer for the ManageFamAuthority to automate Party management based on Hypersub subscription status on Base. From creating a "fam" to linking subscriptions to parties and verifying subscription expirations, you'll learn how to streamline multiplayer Ethereum experiences with this end-to-end guide.
