Hội nghị Hackathon Ethereum x402 công bố: Thanh toán đăng ký, chuyển khoản theo luồng, công cụ hoàn tiền ba đổi mới cùng xuất hiện

【币界】The Ethereum Foundation recently announced the winners of the x402 Hackathon, with several projects showcasing unique features.

Superfluid’s x402-sf has attracted a lot of attention. The highlight of this tool is bringing the traditional internet subscription model onto the blockchain, using end-to-end infrastructure to enable continuous subscription payments, essentially equipping the Web3 world with “automatic billing.”

peterssson.eth’s Cheddr Payment Channels x402 takes a different approach—utilizing the x402 payment channel mechanism, specifically optimized for high-frequency small-value payment scenarios. Through this solution, the efficiency of cyclic transfers and streaming micro-payments is greatly improved, making it particularly friendly for content creators or service providers to settle instant earnings.

BackTrackCo’s x402r addresses a practical pain point. Users pay for data services via x402, but sometimes the money is spent and the service isn’t delivered. In such cases, x402r comes into play—it helps users complete the refund process, protecting consumer rights.

Although the three projects have different focuses, they all revolve around the x402 payment protocol, demonstrating the diverse exploration space within the DeFi payment layer.
