用 DAPPOS @dappOS_com 做了一个 Perps DEX 套利网站,也是我人生中做的第一个网站,简直太绝了! 立即发现 Perps DEX 资金费率套利机会: 最近我没撸啥项目,做的比较多的就是在 Perps DEX 之间做一些价差、费率套利,赚点生活费。其实我一直有想法做一个关于 Perps DEX 套利的网站,但又无从下手。 我知道可以借助AI 帮我做网站,但是往常的 Cursor、Claude Code 、Codex 等 AI coding 工具,对于我这个技术白痴来说还是有点困难。直到我刷到 @dappOS_com 关于 Polymarket Agent SOP 的推文,发现用 @xBubble_ai 做一个网站竟然如此简单,用户仅需陈述:构建一个网站,用于跟踪与伊朗相关的 Polymarket 市场和突发动态,xBubble 马上就做出了一个实用性很强的网站来了! 我用同样的操作生成了一个发现 Perps DEX 资金费率套利机会的网站,我不需要亲自解决服务器环境配置、域名解析、API KEY配置等繁琐技术底层,只需要把我的想法告诉 xBubble ,几分钟内就帮我生成了一个关于发现 Perps DEX 资金费率套利机会的网站,网站包括了套利机会、DEX 对比、收益计算器、观察列表和风险说明等栏目,比我想象的更加齐全! 通过这次 DAPPOS Coding 初体验,我真正感受到了 AI 的强大,原来 OPC 经济(一人公司)早已不是停留在概念阶段了。但你还对 AI 不屑一顾,很多人已经利用 AI 创建了自己的一人公司,实现了阶级的跨越。xBubble 帮小团队和个人彻底抹平了技术雇佣成本,让每一个原本无法变现的细分长尾需求,都变成了能够产生暴利现金流的真实生意。 只有你有点子,就立马去行动,说不定下一个利用 AI 实现阶层跨越的就是你!
