Alerts

Save a rule in Alerts to watch a reference price or a quoted A → B → A cycle. Checks read provider data; they do not sign, trade or spend gas.

Create a rule

Give the rule a name and select its exact asset identifiers. Identical symbols on different networks do not establish that tokens are interchangeable.
For reference prices, choose a USD threshold and an above/below condition. Equality counts as a match.
For a quoted cycle, choose two assets, an input amount, your addresses and a difference threshold in basis points. 100 basis points equals 1%.
Choose a check interval and notification cooldown, then save.

Solana cycle checks use Jupiter. Other supported pairs request dry quotes from NEAR Intents using the entered addresses and amount. Some pairs have no available route.

For RWA monitoring, select Solana RWA cycle, choose an official xStock and enter its starting USDC amount. The worker checks USDC → xStock → USDC using raw mint units. These alerts also exclude gas and do not enable RWA transaction signing. See RWA markets.

Background monitoring

The page reports whether the background worker is online. Saved rules continue to run with the page closed while that worker is running. The inbox refreshes every 15 seconds while visible. If the worker is offline, Check now still performs a manual check.

Intervals are targets, not deadlines. Provider delays and queue load can delay checks. A one-minute rule can miss opportunities that last only seconds. Provider errors are shown on the rule and retried with increasing delays, up to 15 minutes.

Rules last 7 days. Pause and resume to renew a rule for another 7 days. Each browser session can store up to 20 rules. Delete an unused rule to free a slot.

When a notification appears

A matching first check can notify immediately. A continuously matching condition produces one notification. To notify again, a successful check must first stop matching, then match again after the cooldown has passed. Failed checks do not reset this protection.

The inbox keeps the latest 100 notifications for up to 30 days. Marking one as read does not change its rule. Deleting a rule preserves existing notifications until retention removes them.

Read the snapshot

Reference prices are provider market data, not executable swap quotes. The displayed time is when SPANVIO fetched the response; the provider does not supply a market update timestamp through this registry.

Cycle alerts use two sequential minimum-output quotes. They exclude source-chain gas and recovery costs, cannot lock in either leg, and do not establish net profit. Open Arbitrage to request and review fresh execution quotes. A historical notification is never permission to execute its old quote.

Delivery and privacy

Notifications are currently delivered to this browser's private SPANVIO inbox. Telegram, browser push, email and token-holder priority delivery are not connected.
