描述
This project is a creator monetization platform built as a real-world implementation of the HTTP 402 Payment Required (x402) protocol, positioning x402 as a practical payment and authorization layer for content access.
The system uses x402 as a stateless payment gateway, where paid content access is enforced at the protocol level rather than through traditional subscriptions or session-based authentication. When a user attempts to access paid (special) content, the server responds with an HTTP 402 challenge, defining the required payment terms. Once the payment is fulfilled, access is immediately granted without additional user-side signing flows.
To minimize onboarding friction, Privy Auth is used to abstract wallet creation and key management. Users authenticate via email or social login, and a wallet is automatically provisioned in the background. This allows x402-based payments and contract interactions to occur without explicit wallet UI or manual transaction signing, significantly improving UX for non-Web3 users.
Creator uploads are registered as on-chain or indexed assets, tagged as free or paid, with pricing metadata attached. For paid assets, the platform enforces a 1% protocol fee at the payment layer. Revenue distribution is handled programmatically, ensuring transparent and deterministic settlement.
The platform also implements a conditional payment escrow mechanism for tip-based messaging. Tips are locked upon message submission and are only released to the creator’s wallet upon a valid reply. If no response is detected within a 24-hour timeout window, the escrowed funds are automatically refunded to the user, demonstrating a trust-minimized interaction model.
For the hackathon environment, the platform integrates Alchemy gas sponsorship, enabling gasless transactions and removing native token requirements for end users. This further reinforces the protocol-level abstraction of blockchain complexity.
Overall, this project demonstrates how x402 can function as a universal payment primitive for content monetization and asynchronous services, enabling seamless machine-to-user and user-to-creator transactions without traditional Web3 friction.

本次黑客松进展
During the hackathon, we successfully designed and implemented an end-to-end x402-based monetization flow, from protocol-level payment enforcement to content access and revenue settlement. Key achievements include: Implemented x402 (HTTP 402 Payment Required) as the core payment and authorization mechanism for paid content access. Integrated Privy Auth to abstract wallet creation and key management, enabling seamless onboarding via email or social login. Built a Creator Studio allowing creators to upload assets, set pricing, and manage free vs paid content. Implemented tip-based messaging with conditional escrow, including automatic refund logic after a 24-hour timeout. Integrated Alchemy gas sponsorship to enable gasless transactions for end users. Delivered a fully functional demo-ready MVP covering both user and creator flows. This progress validates x402 as a practical protocol for real-world monetization use cases, beyond theoretical or agent-only payments.
