In SocialFi, merging social networking with blockchain technology has been challenging, with no clear successes so far. Social platforms, whether traditional or blockchain-based, need to build relationships, enable interactions, and expand networks. Farcaster sets itself apart by prioritizing user control, privacy, and interoperability, offering a decentralized experience that integrates seamlessly across various applications. This approach may be a significant step toward unlocking SocialFi’s potential.


Farcaster is a decentralized social media protocol built on blockchain, emphasizing interoperability, user autonomy, and privacy. Unlike traditional social networks, it operates without central servers, leveraging the Optimism. This allows developers to create various dApps using smart contracts, ensuring transparency and security.

Farcaster provides a censorship-free environment, giving users full control over their data and audience. Users can manage their social graph and interact across different apps with a single decentralized ID. It’s open-source and permissionless, allowing anyone to build applications through its API.


Farcaster was initiated by a group of blockchain experts and developers passionate about redefining social media. The project is led by Dan Romero and Varun Srinivasan, two early Coinbase employees.

Farcaster has raised significant funding, amounting to $30 million in a round led by A16z in July 2022. This funding round attracted other notable investors, including Coinbase Ventures, Multicoin Capital, and Balaji Srinivasan. Recently, a new funding round led by crypto investment firm Paradigm is expected to elevate Merkle Manufactory, the company behind Farcaster, to a valuation of approximately $1 billion.

How it works?

Farcaster operates on a hybrid architecture that leverages both on-chain and off-chain systems to deliver a seamless and efficient experience. Here’s a closer look at its main components:

1. Registry Contracts:

  • ID Registration: Creates key pairs linked to Ethereum addresses for new accounts.
  • Storage Registration: Handles storage allocation and annual fees for accounts.
  • Key Registration: Allows users to authorize and revoke account ownership.

2. Hubs:

  • These are servers running on traditional hardware that manage data processing, message validation, and synchronization.
  • They ensure fast and reliable data access, supporting real-time application development.

3. Usernames:

  • Fnames: Off-chain ENS names issued for free by Farcaster.
  • .eth Names: On-chain domain names controlled by users, compatible with Ethereum-based applications.

Core Mechanisms

Frames are mini-applications embedded within Farcaster posts, enhancing user experience by providing direct access to various services without leaving the platform.


  • NFT Interaction: Mint, display, or trade NFTs directly within posts.
  • Games: Embed and play games.
  • Content Subscription: Subscribe to newsletters and other media content.
  • Shopping: Purchase goods or services directly within posts.
  • Social Features: Engage in polls, surveys, and other interactive elements.

Technical Implementation:

  • Frames are built using smart contracts and blockchain technology to ensure security and reliability.
  • They operate as independent applications but integrate tightly with the Farcaster network for a seamless user experience.

Hybrid Architecture

Farcaster’s hybrid architecture blends on-chain elements for identity and key management with off-chain elements for data storage and synchronization. This combination ensures efficient performance, reduces costs, and provides a flexible, secure platform for developers and users.



Farcaster has experienced notable growth in daily active users since late January 2024, peaking in March and April. Farcaster currently has around 45,000 daily active users.


Farcaster’s revenue has steadily increased, currently around $1.3 million, with daily revenue averaging $8,000. This significant rise, particularly since March 2024, indicates effective monetization strategies and growing adoption.


Farcaster tackles the challenges of SocialFi by building a developer-driven, community-built ecosystem that prioritizes more than just financial incentives. Unlike many Web3 social platforms that tokenize creators to drive engagement, Farcaster functions as a social layer, supporting various applications like NFTs, music, and games. Its strength lies in maintaining a substantial base of active crypto-native users without depending on a native token. However, it faces challenges such as initial cost barriers and managing content quality in a decentralized setup. Farcaster’s goal is to attract Web3 users by emphasizing decentralized control and user autonomy.
