The L2 Cast Handles

The L2 federated hub uses Farcaster IDs and .cast Cast Handle NFTs on Optimism and Ethereum - we needed a way to filter out bad actors and network spam, requiring our users to pay at least 39 cents a year on Optimism, or gas fees on Ethereum.

Farcaster IDs also function directly on, a perfect usecase for users saving their storage or have expired storage, or during widescale Farcaster network outages.

Builders are free to fork the L2 and remove this requirement or subsitute with their own handle system.
