Etherscan Address Lookup & Whale Tracker

Find out who is behind any wallet and what it holds. For every address you give it, this actor returns the public Etherscan name tag (e.g. "Binance: Cold Wallet 7"), ENS name, labels, native balance and its USD value, token holdings, the multichain portfolio, first and latest transaction, and who funded the wallet. It also lists the top whale accounts of a chain. Works on Ethereum, Base, Polygon, Avalanche and Linea. No API key, no account.

What data do you get?

Address lookup (recordType: "address") — one record per address:

Field	Example
address, chain, url	0xBE0e…33E8, ethereum
nameTag	Binance: Cold Wallet 7 (public Etherscan name tag)
ensName	vitalik.eth
labels[]	[{ slug: "binance", name: "Binance", category: "Cryptocurrency exchange" }, { slug: "cold-wallet" }]
isContract	false
nativeBalance, nativeSymbol, nativeBalanceRaw	1996008.39, ETH
valueUsd, nativePriceUsd	4529002914.46, 2269.03
tokenHoldingsUsd, tokenCount (+ …IsMinimum flags)	8048.03, 310
multichainValueUsd, multichainAddresses[]	16746987193.18, [{ explorer: "BscScan", valueUsd: 12217929116 }, …]
firstTxAge, firstTxApproxDate, firstTxHash	8 yrs 11 days ago, 2018-10-23
latestTxAge, latestTxApproxDate, latestTxHash
fundedBy	{ name: "Binance 105", address: "0x00f9…f243", age: "8 yrs 34 days ago", txHash }
contractCreator, contractCreationTxHash	contracts only, e.g. Bitfinex: Deployer 5
tokenTracker	token contracts only: { name: "Tether USD", symbol: "USDT", priceUsd: 0.9991 }

Top accounts (recordType: "topAccount") — the richest addresses of a chain: rank, address, nameTag, balance, nativeSymbol, percentage (of supply), txCount, url.

How to use

1. Choose Address lookup and paste one or more addresses (0x…), or choose Top accounts to get the whale list
2. Pick the chain (Ethereum by default)
3. Click Start and download the results as JSON, CSV or Excel

Use cases

• Wallet attribution: tell exchange, fund, bridge and contract wallets apart from unknown ones before you act on a transfer
• Compliance & investigations: see who funded an address and when, plus its labels and first activity
• Whale tracking: monitor the richest accounts of a chain and their balances on a schedule
• Lead and counterparty research: enrich a list of addresses with names, balances and holdings in one run
• Data pipelines & AI agents: structured wallet profiles for dashboards, alerts and LLM tools

FAQ

Do I need an Etherscan account or API key? No. The actor reads the public explorer pages.

What is a "name tag" and where does it come from? It's the public label Etherscan shows for known addresses — exchanges, funds, bridges, deployers, well-known individuals. Addresses without a public tag return nameTag: null (their ENS name, if any, is still returned).

Why are transaction dates approximate? The explorer shows the age of the first and latest transaction ("8 yrs 11 days ago"). The actor converts it to a calendar date; the exact transaction is available through firstTxHash / latestTxHash.

Which chains are supported? Ethereum, Base, Polygon, Avalanche C-Chain and Linea. On Ethereum, multichainAddresses also shows the value the same address holds on other chains (e.g. BNB Chain).

What happens with invalid or unavailable addresses? Invalid entries and duplicates are skipped. Addresses that can't be retrieved are listed in the run status — you're never charged for them.
