The confidence to continue.
Know when a paid workflow has reliable evidence to continue.
AI agents × Payments × Verified continuity
RoundWatch observes agent payments, verifies settlement, and preserves durable evidence so autonomous workflows can safely keep moving.
Built on x402. Proven on Algorand TestNet.
01/Product
Work can be autonomous.
Trust needs a foundation.
Watches for the payment event the workflow is expecting.
State advances only from successful settlement evidence.
Settlement state and observation progress survive process restarts.
02/The flow
A payment is a moment.
Verified state is a starting point.
An autonomous agent completes the requested task.
Payment enters the settlement workflow.
RoundWatch waits for successful settlement evidence and persists the resulting state.
The workflow now has durable evidence from which the next action can safely proceed.
Successful settlement evidence is the condition for advancing durable state.
03/Technology
The deterministic core
Workflow continuation
Settlement is established by deterministic infrastructure. A language model does not decide whether a payment settled.
Verified in the Algorand TestNet prototype.
04/Demo
Follow the boundary from completed work to durable evidence, one event at a time.
Verified.
Persisted.
Ready for what’s next.
06 / 06 Ready to continue
Illustrative sequence based on verified prototype behavior. No live connection or payment is made.
05/Resilience
A process can stop. Its evidence shouldn’t disappear with it.
RoundWatch restores durable state and resumes from saved observation progress. A future payment can still be detected after restart.
Verified with a real process restartProcess changes. Evidence remains.
06/Why it matters
Know when a paid workflow has reliable evidence to continue.
Create a clearer boundary between completed work, settlement, and what happens next.
Use durable settlement state instead of relying on volatile process memory.

We’re building RoundWatch with GPT-6 Astra: deterministic settlement infrastructure, developed with intelligent tooling.
The model helps build the system. Verified settlement remains the foundation.
The next action starts with trust
