Watchlist only.
Never the whole market.
Create a watchlist rule, keep the active list here, and read fire history with timestamps. Prices refresh from CoinGecko. Alerts show here in this browser. Rules stay in this browser. Free watchlist is 5 coins and 5 rules.
Active rules — create, list, mute
Create a watchlist rule, then read active status and fire history below. Only starred coins are evaluated. Prices refresh from CoinGecko while this page is open (no live WebSocket feed yet). Rules and history are saved in this browser — there is no account. Delivery is in this browser. No on-chain whale feed.
Smart alerts are watchlist-scoped. Open Watchlist → rules → smart alerts → Ask and star 1–5 coins on the free tier.
Fires with timestamps — this browser
Each row is a watchlist prefilter that actually matched, with the UTC time it landed. Optional webhook delivery is recorded only when the API actually POSTs.
Save a price or 24h rule on a starred coin, then wait for the snapshot to match. Clearing history does not delete the rule. Demo snapshots never fire.
Star coins on the desk. CoinVigil has no accounts and does not invent on-chain whale prints.
