Glossary: Farcaster

Farcaster is a decentralized social network protocol built on Ethereum that lets users create profiles, post content, follow others, and move between different apps while keeping their identity and social connections.

What is Farcaster?

Farcaster Explained

Farcaster is like a social media system that is not controlled by just one company.

On normal social apps, the company controls your account, followers, posts, and what apps can connect to the platform.

On Farcaster, users can own their identity and relationships. This means they can use different Farcaster apps without starting from zero each time.

Think of Farcaster as the shared road system, and apps like Warpcast as cars driving on that road. The apps may look different, but they connect to the same social network.

What Farcaster Means For

Audience	Use Case
Web3 communities	Build social communities where users can own their identity, followers, and connections across apps.
Developers and founders	Create new social apps, clients, or mini apps on top of an existing decentralized social graph.
Creators and users	Post, follow, and interact in a social network where their profile and audience are more portable.

Examples

A creator uses a Farcaster app to post updates and build an audience. If they switch to another Farcaster app, they can keep their identity and social graph.
A developer builds a niche social app for crypto traders using Farcaster, instead of creating a brand-new network from scratch.
A Web3 project uses Farcaster to engage its community through posts, discussions, and interactive experiences.
A user posts a “cast,” follows other accounts, and joins conversations in a way that feels similar to X or Reddit, but with more user-owned identity.
