Crypto wallet and whale tracking tools

Following an address is not knowing whose it is

Twenty-two cards carry the wallet-tracking flag, each for a different reason. A chain is public, so following an address — what it holds, what it sent and to whom — is the cheap part. A reader who types "whale tracker" usually wants one of three things that are not.

A name is a judgement, not a fact. An address has no owner field. When a product says a wallet belongs to an exchange, a fund or a named person, somebody made that attribution from clustering, behaviour and off-chain evidence, and nothing on the chain confirms it. The label set is what you pay for, and most label sets carry no date. Why that matters is argued on the on-chain analytics page rather than repeated here.

"Smart money" is a cohort somebody defined. A list of wallets that did well is a threshold a vendor chose, over a set it chose, and membership cannot be checked from outside.

Your own wallet in a portfolio tab is a different job. Several cards carry the flag because you can paste in a read-only address and see its balance beside your exchange accounts. That is bookkeeping about yourself, and it stops at balances.

The groups below sort what the flag cannot.

Who owns this address: the labelled platforms

Nansen and Arkham are bought for this, which is why on-chain analytics is the first group in the listing. Nansen resolves addresses to entities and to its own Smart Money cohorts and builds every screen on that attribution; it puts the count at 500 million labelled addresses, documents 38 chains and accepts 20 of them on the labels endpoint. Its labels are undated and the endpoint has no look-back, so re-running last week's query can return different numbers because a label moved underneath it. Arkham lets you search a person, company or fund and shows the wallets it has attributed to them, graded: verified at 98% confidence or better, predicted at 80% or better — a badge that does not survive a screenshot. The two side by side are Nansen vs Arkham.

Labels also come as columns rather than screens. Allium has identity tables over 400M+ curated addresses inside a SQL warehouse, with no published price and no revision date for the set. Bitquery sells labels as a 99-dollar-a-month add-on — 169M addresses on 12 chains, each row carrying a RecordedAt timestamp, which is more than most label sets will tell you. Santiment and the API under it, SanAPI, label exchange, fund and whale addresses on Ethereum only. The Etherscan API has an address name-tag endpoint, on its Pro Plus plan and nowhere below it.

Which wallets move together: one token's holders

Bubblemaps answers a narrower question, and its output is the one here you can check yourself. It draws a token's top 250 holders and a line between any two that have transferred to each other. A line is a transaction, verifiable on an explorer; whether it means one owner, an exchange withdrawal, a payroll or an airdrop, the picture does not say.

The map is recomputed within six hours rather than live, and the card records it as delayed. Fifteen chains, no Bitcoin. The app is free; P&L, cross-chain analysis and the top-1,000 map are held for holders of the vendor's own token at no published threshold — a token threshold is not a price — and the API starts at 170 dollars a month with no free tier. There are no webhooks, so no alert.

What a wallet holds and made: address data by API

For a developer building a portfolio view, a token dashboard or an agent, the flag means endpoints that take an address and return balances, transfers, positions or PnL. No name comes back. Where each one stops is mostly a question of chains:

• Birdeye Data API marks every holder, balance, portfolio, net-worth and PnL endpoint Solana-only. Wallet endpoints are in beta at 5 requests a second on every package, and PnL for several wallets in one call is Business, at 499 dollars a month.
• Mobula API covers EVM chains and Solana, and bills portfolio, history and position calls one credit per chain queried — the wider the lookup, the faster the credits go.
• Etherscan API is 33 EVM mainnets and nothing else, with no websockets and no webhooks. Its free, Lite and Standard plans are licensed for personal and research use; anything run by or for a business starts at Advanced, 299 dollars a month.
• CoinGecko API adds wallet balances and token transfers by address to its price data, with no alerts.
• Amberdata serves current and historical balances, transfers and batch portfolio lookups, fully on Bitcoin, Bitcoin Cash, Ethereum and Litecoin and with no Base, from 600 dollars a month.
• Coin Metrics goes down to balance updates for a single account in Atlas, across 358 assets.

The query engines return the same thing as rows to join. Bitquery's self-service plans keep raw on-chain data four hours on EVM chains and eight on Solana, with transfer and balance history a per-chain add-on; Footprint Analytics has wallet pages that profile an address rather than name it.

Positions on one perpetual DEX

On a derivatives product, "whale" usually means a wallet's open position on Hyperliquid, which publishes positions by address. 0xArchive serves account positions by wallet and order history; its Free plan reaches every route over a 30-day window, and webhooks on activity by watched wallets start at Build, 49 dollars a month. The CoinGlass API has Hyperliquid whale alerts and positions above 1 million dollars notional from its 95-dollar Startup plan, with no webhooks and no free tier. The Laevitas API has wallet positions by address on its HyperCore surface, and no free tier. CoinAnk is a website that lists Hyperliquid positions by address with entry time and running profit; the free version is a preview, and the real-time feed is VIP at no published web price.

None of it reaches past the venue: a position on a centralised exchange is visible to none of these cards.

Your own wallet beside your exchange accounts

Altrady attaches read-only addresses — no API key, no private key — on BTC, LTC, ETH, BSC, TRX, XRP and EGLD, with tokens only on the two EVM chains: a portfolio line item, not a chain explorer. Coinigy tracks wallets beside connected exchange accounts, and its own upgrade prompt lists unlimited wallet tracking among what the free tier lacks. GoCryptoTrader looks up Ethereum and ERC-20 balances through Ethplorer, Ripple through XRPScan and other coins through CryptoID, each with a key you supply. DEXTools sells wallet info and a positions tracker on its paid tiers. These live in trading terminals, trading bots and charting platforms, and the reasons a total comes out short are in tracking one portfolio across exchanges and a wallet.

Real time, alerts and where the free tier stops

Latency. Most of these cards record real-time data; Allium, Bubblemaps and Footprint Analytics record delayed. On a labelled dashboard "real-time" means what Nansen says of its own: seconds to a couple of minutes behind the chain. Santiment's free dashboard runs 30 days behind.

Alerts. Nansen, Arkham and 0xArchive alert on wallet activity as described above. Santiment has alerts too — three on the free tier, expiring after 30 days, with webhooks from Pro. Etherscan has to be polled, Bubblemaps has no webhooks, and Allium's SQL product schedules nothing. Footprint's alerts fire on a chart's threshold, not on an address.

The free tier. Following is often free; naming rarely is. Nansen's free plan buys exactly one labels lookup and then never refills far enough for another. Arkham's platform is free and its API starts at 100 dollars a month, or 0.20 dollars a credit by the call. Allium, Bitquery, CoinGlass, Laevitas and Amberdata have no free tier at all.

What is not here

A list of wallets worth following. A leaderboard of profitable addresses is a vendor's definition, not a dataset, and CoinAnk's card flags its Smart Money Radar and AI modules for selling calls. Copy-trading, wallets themselves and tax services are outside this catalogue's scope: this page lists software that reads addresses, never a reason to act on what one does.
