Verifiable settlement for autonomous agents

3 followers

RoundWatch gives autonomous workflows a durable boundary between completed work and what happens next. It observes x402 payments, advances state only after verified settlement evidence, and preserves progress across restarts so agents can continue safely.

What real task does your product handle with GPT-6 Astra?

Maker

GPT-6 Astra is the engineering agent helping turn RoundWatch from a verified x402 prototype into a production-ready product. It inspects the existing codebase, implements and audits the public experience, validates build and accessibility, and iterates from browser QA. RoundWatch keeps settlement verification deterministic: Astra helps build and reason about the system, but it does not decide whether a payment settled.

Hi Product Hunt 👋 I built RoundWatch around a simple problem: autonomous agents can complete useful work, but the workflow still needs reliable evidence that payment actually settled before moving on. RoundWatch observes x402 settlement, advances state only after successful settlement evidence, and persists that state across restarts. The goal is to give agentic workflows a durable boundary between “work completed” and “safe to continue.” The current prototype has been validated on Algorand TestNet, including restart recovery and future-payment detection after the observer is already running. I built this launch with GPT-6 Astra for the Astra Challenge. Astra helped shape the product, architecture, and public launch experience, while settlement verification itself remains deterministic infrastructure. I’d especially value feedback from people building agent infrastructure, x402 services, or payment-driven workflows: where would a durable settlement observer actually save you engineering time?

What happens if payment settles and your agent crashes before saving it?

So I ran into a pretty annoying problem while building RoundWatch, and I m curious how others deal with this.

Catching the moment a blockchain payment happens? Honestly, that s the easy part.

The real headache starts when something breaks mid-flight:
Your agent finishes the job -> the payment goes through on-chain -> but the system crashes right before updating the local state.

When everything boots back up, how does your system know what actually went down? If you don't handle this right, you risk double-spending, losing track of progress, or getting stuck trying to resolve a payment that s already settled.
