Project Description
World.fun reimagines social tokens by combining the viral mechanics of platforms like pump.fun with Worldcoin's sybil resistance. Users can create their own ERC20 tokens with custom metadata, which are then traded through an automated market maker (AMM) with a bonding curve mechanism.
The key innovation is the integration of World ID verification, ensuring that each creator can only launch one token. This prevents common manipulation tactics like creating multiple tokens or using bot accounts, making the platform more fair and sustainable.
The AMM uses a bonding curve that automatically adjusts token prices based on supply and demand. When users buy tokens, the price increases along the curve; when they sell, it decreases. This creates natural market dynamics while maintaining constant liquidity.
- Each token has its own profile page displaying:
- Token price and market cap
- Creator information
- Custom description and image
- Trading history
- Holder statistics
The platform features a discovery page where users can browse all available tokens, sort by various metrics, and easily trade any token with ETH.
How it's Made
World.fun was built to make social tokens accessible and fair for everyone. The key innovation is using World ID's human verification to prevent manipulation - something that has plagued previous social token platforms.
The architecture focuses on three core pillars: Fairness Through Identity: We leverage World ID's zero-knowledge proofs to verify each creator is unique without compromising privacy. This prevents sybil attacks while keeping the platform pseudonymous.
Sustainable Trading: Rather than allowing arbitrary pricing, we implemented a bonding curve that automatically adjusts token prices based on supply and demand. This ensures there's always liquidity and creates more predictable trading dynamics.
User Experience First:The platform is designed to feel familiar to web2 users while maintaining web3 capabilities. We focused on making token creation and trading as simple as possible, with instant transactions and real-time price updates.
The most challenging aspect was balancing decentralization with user experience. We solved this by using a hybrid approach - decentralized token contracts and trading mechanics, combined with a modern frontend that abstracts away the complexity.
