Nous Research, in partnership with NVIDIA and Stripe, ran the Accelerated Business Hackathon — challenging builders to create Hermes Agent-based agents that “earn, spend, and run real operations at any scale.” The event drew 292 submissions; Nous announced three winners with real, named technique detail, headlined by Custodian, a safety kernel that gates an agent’s real-world actions with cryptographic receipts, a human kill switch, and self-policy-rewrite detection — run against real Stripe payments.
Key Takeaways
- Event. Accelerated Business Hackathon, Nous Research + NVIDIA + Stripe, 292 submissions. Brief: build Hermes-based agents that earn, spend, and run real operations at any scale.
- 1st place — Custodian (Daniel LaForce, @MHArgonaut). A safety “kernel” sitting between the agent and real-world actions like payments:
- Approves or denies proposed actions before they execute.
- Maintains cryptographic receipts of what was approved or denied.
- Includes a human kill switch.
- Escalates on self-policy-rewrite detection — flags when an agent attempts to modify its own governing policy.
- Ran on real Stripe payments during the hackathon, not a sandboxed demo.
- Prize: 5k Stripe credits. Code was linked in the original post (not captured in this raw source — see Open Questions).
- 2nd place — Mom-n-Pop Skills (Scott Hewitson, @Hewi333). Built for non-technical small-business owners: operates entirely via Telegram for CRM, lead handling, pricing estimates, Stripe payment links, financial analysis, and marketing — with all actions requiring owner approval. Prize: 3k Stripe credits.
- 3rd place — CashFromChaos (David Diaz, @davddiazm). An end-to-end recommerce agent: from a photo + short description, it identifies the item, chooses marketplaces, sets prices within a seller-defined CommercePolicy (floor price, counter rules, spend limits), drafts listings, negotiates, handles Stripe payments/escrow, manages fulfillment, and releases payouts. Built in Next.js using Hermes + Nemotron. Prize: 1k Stripe credits.
- Common thread across all three winners. Real Stripe integration, human-approval gating, and a policy layer that constrains what the agent can spend or approve on its own — the hackathon’s brief (“earn, spend, run real operations”) was answered with safety-first architectures, not just capability demos.
The Custodian pattern in context
Custodian’s self-policy-rewrite detection is a sharper, hackathon-proven parallel to a capability Nous has been building into Hermes core: the Write Gate (announced 2026-06-10, documented in the Security Model article), which extends approve/deny gating to the agent’s own self-improvement actions — memory updates, skill updates, and skill creation. Custodian applies the same instinct — don’t just gate dangerous shell commands, gate the agent modifying its own rules — as a standalone kernel sitting in front of real payment rails, with cryptographic receipts and a human kill switch layered on top.
All three winners also demonstrate real-world use of Stripe-connected Hermes agents, complementing the official Stripe Payments Skill Suite (stripe-link-cli, mpp-agent, stripe-projects) — though the source doesn’t specify which winners used the official skill suite versus a custom Stripe integration.
Try It
- Read the original thread and the linked Custodian code — the code link wasn’t captured in this raw source; check @MHArgonaut’s posts or the NousResearch thread replies for the repo.
- If you’re building an agent that spends real money, use Custodian’s three primitives as a reference safety-kernel shape: (a) an approve/deny layer between agent and action, (b) cryptographic receipts of every decision, (c) a human kill switch that isn’t itself agent-controlled.
- Compare your own approval-gate design against Hermes’ existing seven-layer defense-in-depth model plus the incoming Write Gate — Custodian is effectively a specialized, hackathon-validated implementation of a “capability broker” sitting between agent and payment rail.
- Non-technical operators: Mom-n-Pop Skills’ Telegram-first, owner-approval-gated pattern is a concrete template for running CRM/pricing/marketing through Hermes without touching a terminal.

Open Questions
- Custodian’s code link was not captured in this raw source. The original post is described as containing a code link — the actual repo URL, license, and implementation detail (how “cryptographic receipts” are constructed, what triggers self-policy-rewrite detection) need a follow-up pull.
- Hackathon dates, judging criteria, and total prize pool beyond the three named winners are not given.
- Whether any winning technique will be upstreamed into Hermes core (especially Custodian’s safety-kernel pattern or CashFromChaos’s CommercePolicy schema) is not stated.
- Which winners used the official
official/payments/*Stripe skill suite versus a custom Stripe integration is not specified in the source.
