How to Build a ManageFamAuthority Indexer for Hypersub Subscriptions

Onchain Experiments

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.
