I made a small tool myself: funding rate arbitrage
Built a funding-rate arbitrage screener that uses Jev to pick which long/short pairs to check first.
The original post, translated
I made a small tool myself: funding rate arbitrage portfolio screening. See which side to go long/short, roughly how much is left after fees, and why to look at this group first. It's still very early, the webpage features are free for now. Feedback and feature requests welcome. https:// humarb.com Used @typesafeai's Jev, payments integrated with @0xinfini. If you have bugs or ideas, replying to this post is fine too, TG: https:// t.me/+tAo58YGEsqwxY TNl …

自己做了个小工具：资金费套利组合筛选。 看哪边做多/做空、扣费后大概剩多少、为什么先看这组。 还很早，网页功能先免费。欢迎挑刺、提需求。 https:// humarb.com 用了 @typesafeai 的 Jev，支付接 @0xinfini 。 有 Bug 或想法回这帖也行，TG： https:// t.me/+tAo58YGEsqwxY TNl …

Where this case fits
Filed under general Jev builds. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Browse the full case library for the work it sits next to.
