Post to Mine: Understand the Tokenized Forum subs.fun with Integrated AI Agents
How does subs.fun combine posting content with earning money?
Author: Fairy, ChainCatcher
Against the backdrop of centralized platforms dominating user attention and compressing creators' earnings, subs.fun has emerged with a mission to revive the internet's original ideals: building a community-driven, value-sharing digital universe.
By integrating AI technology with crypto-economic mechanisms, subs.fun has created a new platform where users can post, trade within tokenized subforums ("subs"), and earn rewards for content contributions—exploring new models for community operation and value distribution.
So, how does posting and earning work together on subs.fun?

How Does subs.fun Work?
subs.fun enables trading, posting, and earning within subs. Each sub is a subforum backed by its own token and equipped with a dedicated AI agent called a Subagent. When members contribute insights, data, and discussions, the subagent incorporates them into its knowledge base and rewards contributors accordingly.
Each sub generates a new token upon creation. Accessing a sub requires holding its corresponding token—a mechanism known as token gating.
Members help the subagent build its knowledge system by posting links, content, and likes. The more likes a post receives, the higher the weight the subagent assigns to its content during learning. Members are rewarded with sub tokens for publishing high-quality content and engaging actively.

Team Background
Alvin Hsia is co-founder of subs.fun and also serves as co-founder and CEO of Shadow. He graduated from UCLA with dual bachelor’s degrees in Business Economics and Computer Science, where he was actively involved in various student organizations and activities.
Alvin brings extensive experience in internet product management and Web3 entrepreneurship. He worked at Edmodo as a Product Analyst and later Product Manager for three years.

In 2020, he entered the Web3 space with a brief role at Goldfinch, a decentralized credit protocol. In 2023, he founded the developer platform Shadow, launching subs.fun in 2025.
Jonathan Becker, founding engineer at subs.fun, has five years of engineering experience and has previously held engineering roles at Chainalysis, Transpose, and Bubbles. He now serves as founding engineer for both subs.fun and Shadow. At Shadow, he primarily focuses on designing and developing Rust-based blockchain indexing solutions and data pipelines, aiming to build highly available, production-grade systems.

How to Launch a Sub on subs.fun?
On the subs.fun platform, users can create and manage a tokenized subforum (Sub) to incentivize community participation and reward contributors. Here are the steps:
1. Set Basic Information
First, users need to define basic details for the subforum, including name, symbol, description, and image.
2. Provide Seed Data for the Subagent
The subagent learns from curated information provided by the user. The more relevant, high-quality, and unique the data sources, the more specialized and valuable the subagent becomes.
Supported content types: blog posts and subreddits, YouTube videos, Apple podcasts, Twitter/X posts, PDF files and research papers, custom text notes, CSV files containing URLs.
3. Customize Your Subagent
On subs.fun, a subagent’s personality and behavior can be tailored to your needs. You can configure:
-
Profile: Create a backstory and lore for your subagent.
-
Knowledge Rigor: Determine whether the subagent should strictly base its responses on content and data within the sub.
-
Platform-Specific Behavior: Adjust the subagent’s interaction style and writing tone across different platforms (e.g., Subs, Twitter/X).
4. Tokenize and Launch
Launching a sub requires a one-time fee of 0.5 SOL, which includes 1,000,000 sub tokens and covers Solana network costs. As the sub creator, you automatically receive 1,000,000 sub tokens. You may choose to purchase additional tokens after launch for use in community funds, member giveaways, etc.
Once launched, the sub tokens become available for anyone to buy. Over time, the sub will continue evolving as the subagent learns and grows through community contributions.
To join someone else’s sub, users must hold at least 10,000 sub tokens and maintain this minimum balance to retain access.
