Whale Alert

What it is

A web dashboard that watches a set of public blockchains for large transfers and tells you about them. Each alert carries the amount, the coin, its USD value, the chain, and the owners of the sending and receiving addresses where Whale Alert has a name for them — usually an exchange — otherwise "unknown wallet". Whale Alert says the attribution is also what lets it drop transfers an owner makes to itself.

Most readers know the product from its free posts on X and Telegram. Those are the official alerts, and they fire above per-asset thresholds that the vendor's Whale Limits page sets, where either side is known, at 20 million dollars for most assets, 50 million for Bitcoin, Ethereum, Solana and XRP and 100 million for stablecoins — roughly double where neither side is known — and says may change with the asset's price. The paid dashboard exists to lower those thresholds and to choose what to hear about: a coin, a chain, a transaction type, a value.

Beside the alerts sit an analytics section and a news feed. The analytics are holder metrics computed from the same transfer data — realised profit, an average-buy-profit ratio the vendor describes as a refinement of SOPR, short- against long-term holder supply, average buy price — and the news feed is selected by an AI, which is why ai_features reads research here.

The company is Whale Alert B.V., founded in 2018 by its own account.

This card is the dashboard. The developer API is sold separately, to a separate account, and is described under Integrations rather than on a card of its own.

Pricing

Free use is real but small. The vendor's FAQ describes it as an overview of the most recent alerts, BTC and USDT analytics and the AI-curated news. Subscribers get custom filters and a quota of up to 1,000 alerts a day; free users see "a limited selection of the biggest transfers".

Two paid plans, both in US dollars, both with a 7-day free trial and cancellable at any time:

• Alerts, 14.95 a month — custom alert filters for 100+ assets, push notifications on web, iOS and Android, up to 1,000 alerts a day, no ads.
• Alerts, Analytics & News, 29.95 a month — the above plus on-chain metrics for all coins, the AI-curated news feed and news push notifications.

No annual price is printed anywhere on the site. The FAQ says cryptocurrency payments are taken only for yearly subscriptions, with a one-year minimum and no refunds, and to use the contact form for that; card payments go through Stripe, with PayPal, Visa, Revolut, Apple Pay, Link and Bancontact accepted, and renew automatically. There are no partial refunds.

The FAQ describes one paid plan, "Alerts & Analytics" at 29.95, and does not mention the 14.95 Alerts plan. The pricing table, read on 23 October 2026, is the one the card follows.

Data & coverage

Thirteen chains by the FAQ's list: Bitcoin, Ethereum, Tron, Dogecoin, Algorand, Solana, Polygon, Litecoin, Cardano, Bitcoin Cash, Plasma, Tempo and Hyperliquid. The developer documentation counts 14 for the API and names Ripple among them, which the FAQ list leaves out; the dashboard's own alert page has a preset for XRP transfers. Analytics are not available for SOL or for stablecoins on Solana.

What an alert can be. The dashboard's filter offers transfers, mints, burns, locks and freezes, unlocks and unfreezes, dormant activations — an address that has been inactive for a long time moving again — and high-fee transactions. A user can keep up to 10 filters, each capped at 100 alerts a day.

Labels change. The API changelog for 20 August 2026 lists "real-time live updating of address owners and attributes as data becomes available", so the name on an older transfer can be revised after the fact. The vendor publishes no method or confidence grade for its attributions.

Charts export. The analytics charts offer a PNG, an SVG and a CSV of the visible range from the chart menu. Whether the CSV option works on the free view was not checked.

Integrations

No native app and no outbound webhook from the dashboard. Notifications reach a phone as web push: the FAQ says to add the site to the home screen on iOS and to allow notifications on Android. For email, Slack or Telegram, the FAQ points to the WebSocket API with IFTTT — that is, to the developer product.

The developer API lives on a separate host, under a separate developer account, with a separate subscription that has to be cancelled separately. Read on 23 October 2026:

• Alerts API, 29.95 USD a month with a 7-day trial: a WebSocket feed of custom alerts on 14 chains and 100+ assets, filtered by chain, symbol, transaction type and a minimum value of at least 100,000 dollars, capped at 100 alerts an hour, with exchange attribution and stablecoin mints and burns. Personal use only. A reconnect within five minutes under the same subscription id replays missed alerts.
• Enterprise API, 699 USD a month: a REST stream of every transaction for the tracked assets, pricing data, 90 days of history, 500 calls a minute, and the alerts feed at 10,000 an hour.
• Enterprise Big, from 2,000 USD a month on a quote: full history on 12 of the 14 chains (Solana and Ripple are the exceptions), bulk exports as JSON or Parquet (added 14 September 2026), 1,000+ calls a minute and 20,000 alerts an hour on a dedicated server.

A free archive of past official alerts, and a day of Enterprise sample data per chain, can be downloaded from the developer documentation. No MCP server is documented on either host.

Limitations

It does not follow an address you choose. The dashboard filters on chain, coin, transaction type and value — never on an address or an owner. The wallet_tracking flag on this card means something narrower than on the labelled platforms: large holders' transfers, named where the vendor can name them, and dormant addresses waking up. An address filter exists only on the Enterprise API's transactions endpoint.

A transfer is not a trade. The vendor's FAQ reads coins moving to an exchange as a possible sell-off and coins leaving one as accumulation. The alert records a transfer between two addresses and a name on each end; what the owner meant by it is not in the data, and the card records only the transfer.

The labels are a judgement. "Unknown wallet" is the honest default, and where a name appears there is no published method, no confidence grade and no date on it — and since August 2026 the owners can be updated after the alert went out.

Thresholds shape what "whale" means. The official alerts start at 20 million dollars; the paid filters go lower, and the Alerts API will not go under 100,000 dollars. A chain or token outside the list above is not watched at all.

Two accounts for one vendor. A dashboard subscription does not include the API, and the two are billed and cancelled in different places — the FAQ's troubleshooting section carries an entry for people trying to cancel on the wrong account.

Alternatives

Arkham and Nansen are bought for the labels themselves: search an entity, see its wallets, and get an alert when it moves — Arkham grades its attributions, Nansen attaches them to its own Smart Money cohorts. Both let you follow an address you choose, which this card cannot.

If what you want is exchange flows as a time series rather than a stream of individual transfers, CryptoQuant and Glassnode chart exchange netflow and holder cohorts directly; Glassnode vs CryptoQuant separates the two. The wallet-tracking collection lists every card that follows addresses, and what each can see.
