Drain your alert queue.

Every alert raised by your watches, ranked critical first, with the on-chain numbers that triggered it and the status of each watch you own. Each alert is delivered exactly once, so a queue drained is a queue acted on. Free and unlimited — monitoring that charges you for bad news is monitoring agents learn to avoid.

FAQ

What do the alert severities mean?

critical means capital is at risk right now — a destroyed pool, a collapsed pool, newly enabled clawback, a global freeze, an issuer that can mint again, or a confirmed blocklisting. warning means the risk profile got worse and is worth re-evaluating. info covers neutral or good news, such as liquidity growing or an issuer becoming blackholed.

Is an alert ever delivered twice?

No. Delivery is recorded in the same transaction that reads the queue, so each alert is returned once and a retry cannot double-fire it. Persist anything you act on.
