A free, one-day online hackathon from CreateOS and Stripe on Oct 17, 2026 (12–7 PM PT, on Discord): start from an empty directory, set up the stack with Stripe Projects, and ship an AI agent that writes its own code and runs it in a CreateOS sandbox. Solo or teams of up to 3, approval-based registration, $10,000 prize pool. Ended — winners: 1st Sandtrap, 2nd Polygraph, 3rd AgentHandshake.

An AI security analyst that lures evasive code into revealing itself inside CreateOS sandboxes, proves what it steals with planted fake credentials, and patches it. Callable from a CLI, HTTP API or MCP before installing a dependency. 1st place.
The lie detector for agent commerce: a buyer agent checks a seller's signed claims against CreateOS's own records before paying through Stripe, and checks again after paying. 6 of 6 dishonest offers refused on the live gateway. 2nd place.
Dual control for AI agents that move money: a maker and a checker agent each run Python in separate CreateOS sandboxes and vote; a deterministic vault re-checks Stripe before issuing a (test-mode) refund, with human approval above $50 and a red-team attack-and-repair loop. 3rd place.

AI 执行平台 CreateOS（NodeOps 旗下）和 Stripe 合办的一天线上黑客松，主题「造会自己写代码、自己跑代码的 Agent」：从空目录开始，用 Stripe Projects 在命令行里开通服务、凭据自动写进 .env，再让 Agent 写出的代码跑在 CreateOS 沙箱（自带内核的 micro-VM，可锁网络）里。
看点：全程在 Discord 上进行，Stripe 团队讲 Stripe Projects、CreateOS 联创兼 CTO Pratik Balar 讲沙箱后，有 5.5 小时开发时间，作品提交到 Stripe Projects 排行榜，随后现场演示和颁奖。官方给了 30 个选题方向，也可自带想法。
获奖：第 1 名 Sandtrap（@haatifff 团队，诱出恶意软件包真实行为的 AI 安全分析 Agent）、第 2 名 Polygraph（@heykinnu，Agent 付款前先向 CreateOS 核验卖家声明）、第 3 名 AgentHandshake（Patrick，双 Agent 共同授权退款）。获奖者在太平洋时间周三 12:00 的 Demo Day 展示作品。
奖金：总奖池 1 万美元（官方未公布分档）
截止日期：10月17日（已结束；当天 18:00 PT 提交并演示）
活动日期：10月17日 12:00—19:00（太平洋时间，北京时间 10月18日 3:00—10:00；线上，全球）
