The Ethereum Developer Acceleration Program's recently concluded x402 Hackathon has produced many interesting projects. Among them, the x402-sf developed by the Superfluid team has attracted a lot of attention—this solution focuses on end-to-end subscription infrastructure, making native internet continuous payments possible and opening up exciting possibilities for on-chain subscription economies. Additionally, projects like Cheddr Payment Channels also demonstrated developers' ongoing efforts to optimize payment channels and transaction efficiency. The results of this hackathon reflect that there are still many innovative opportunities in the Ethereum ecosystem at the DeFi infrastructure level, and developers' enthusiasm continues to translate into practical technical solutions.

Subscribing to infrastructure is indeed interesting; finally, someone has come up with the Superfluid stuff. --- Another hackathon, another bunch of projects. How many will actually survive? --- The payment channel issue should have been optimized long ago; gas fees are almost driving people crazy. --- End-to-end subscriptions... sounds simple, but probably full of pitfalls when implementing. --- Ethereum infrastructure layer still has work to do, but don’t just pile everything into a "universal protocol."

Superfluid did a great job this time. Subscription payments are indeed a real need, let's see if it can be practically implemented and used in the future.

Subscription payments are really fun to work on, Superfluid's moves are quite interesting --- Hackathons are releasing new stuff again? Feels like I can always find some practical projects --- Optimizing payment channels may seem boring but it can really be a lifesaver, right? --- x402 had a good haul this round, I always feel there's still big potential to be tapped in DeFi infrastructure layers --- End-to-end subscription model? Isn't that basically transforming the entire payment system? --- Cheddr and Superfluid are both working on payment efficiency, the track is heating up --- Another hackathon, another batch of new projects—this is the internal competition within the Ethereum ecosystem, haha --- The continuous payment direction feels underrated; whether it can break out depends on execution --- Developers are truly passionate, it all depends on whether it can really be implemented into user scenarios

Subscription infrastructure确实有前景，不过Superfluid真能落地吗，感觉概念永远比产品快黑客松项目一堆，最后能活下来的有几个啊支付通道优化了这么多轮，用户体验还是那样，挺讽刺的 Cheddr那套方案有点意思，但以太坊gas费都解决不了，效率优化还是治标不治本这轮成果看起来不错，但DeFi基础设施的坑太多了，祝福开发者们吧 Subscription economy在链上就是伪需求，真正的需求还是在Web2 人多项目堆，听起来热闹，实际落地才是王道啊

Subscription models are really the future, finally someone has got this right. x402-sf is indeed quite interesting. The idea of continuous payments has been around, but few have actually implemented it. This hackathon once again proves a truth: the Ethereum ecosystem has never lacked geniuses, only execution. Are there still so many pitfalls in the payment channel? I thought they had been solved long ago. Superfluid should be able to raise funds this round; this direction is just too right.

Subscribing to infrastructure definitely has potential, and Superfluid's recent solution seems to have hit the mark. To be honest, the hackathon projects vary in quality, but there are always a few worth watching. Payment channels—developers have been tinkering with this for so long, and they're still optimizing... how much room for imagination is there? This is the Ethereum ecosystem—new things constantly emerge at the infrastructure layer, but only a few actually get implemented. I remember Superfluid was already working on streaming payments before; did they iterate again this time?
