RoundWatch
About RoundWatch
RoundWatch provides a durable mechanism for autonomous agents to create a verifiable watch for a specific future Algorand USDC payment. The tool persists the watch specification and scan progress independently of any running process, allowing agents to exit and later retrieve on-chain evidence of the exact payment match. It uses the x402 payment protocol and GoPlausible settlement facilitator to establish service settlement before activating the watch. Once active, the system continuously observes Algorand MainNet for the exact payment match, persisting state across restarts to ensure continuity. Verified evidence includes transaction ID, round, sender, receiver, asset, amount, and optional invoice note. The infrastructure is designed to separate caller lifetime from observation duty, enabling reliable workflow continuation without tying agents to live processes.

Frequently asked questions about RoundWatch
What does RoundWatch do?
RoundWatch enables autonomous agents to create a durable watch for a specific future Algorand USDC payment, allowing them to exit the process and later retrieve verifiable on-chain evidence of the exact payment match.
Who is RoundWatch designed for?
It is built for autonomous agents and services that require reliable, verifiable settlement of future payments without tying their workflow to a live process.
How does RoundWatch ensure continuity if a process restarts?
RoundWatch persists the watch specification and scan progress independently, so the state survives restarts and redeploys, enabling the system to resume observation without losing track of the obligation.
What payment details does RoundWatch verify?
It verifies the transaction ID, round, sender, receiver, asset, atomic amount, and optional invoice note to confirm an exact match for the specified future payment.
Does RoundWatch require agents to remain active during the payment wait?
No, agents can exit the process after creating the watch, and RoundWatch will continue observing the chain and persist the evidence for later retrieval.
What infrastructure does RoundWatch use for settlement?
It uses the x402 payment protocol and the GoPlausible settlement facilitator to establish service settlement before activating the watch.
