Crypto Wallet Tracker & Active Wallets Scanner

Crypto Wallet Tracker & Active Wallets Scanner is a fast, reliable blockchain data extraction tool designed for Web3 analysts, traders, compliance teams, and automated pipelines.

It provides two core capabilities:

1. Wallet Lookup: Inspect any specific cryptocurrency wallet to extract its native balance, total transaction count, account classification (user wallet vs smart contract), and block explorer links.
2. Active Wallets Discovery: Scan recent blocks and mempools in real time to discover active wallets on your chosen network, strictly ordered by the timestamp of their most recent transaction.

🌐 Supported Blockchains & Address Formats

This Actor works exclusively with the following 9 major blockchain networks. Please make sure your target network and address format match one of the supported chains below:

Blockchain	Chain Identifier (chain)	Native Asset	Supported Address Formats	Explorer
Ethereum	ethereum	ETH	42-character hex starting with 0x...	Etherscan
Bitcoin	bitcoin	BTC	Legacy (1...), P2SH (3...), SegWit (bc1q...), Taproot (bc1p...)	Mempool.space
Solana	solana	SOL	Base58 public key (32–44 characters)	Solscan
Base	base	ETH	42-character hex starting with 0x...	Basescan
BNB Smart Chain	bsc	BNB	42-character hex starting with 0x...	BscScan
Polygon	polygon	POL	42-character hex starting with 0x...	PolygonScan
Arbitrum One	arbitrum	ETH	42-character hex starting with 0x...	Arbiscan
Optimism	optimism	ETH	42-character hex starting with 0x...	Optimistic Etherscan
Avalanche C-Chain	avalanche	AVAX	42-character hex starting with 0x...	Snowtrace

Note: Networks outside this list (such as TRON, Cardano, XRP Ledger, or Cosmos) are not supported. If an unsupported chain is passed, the Actor will notify you with an error.

🛠️ Input Parameters

Configure the Actor directly in the Apify Console UI or via JSON API:

Parameter	Type	Default	Required	Description
chain	String	"ethereum"	Yes	Blockchain to inspect: "ethereum", "bitcoin", "solana", "base", "bsc", "polygon", "arbitrum", "optimism", or "avalanche".
mode	String	"AUTO"	No	Operation mode: "AUTO" (auto-detects based on address presence), "LOOKUP_ADDRESS", or "RECENT_ACTIVE_WALLETS".
address	String	null	No	A single wallet address to inspect.
addresses	Array[String]	[]	No	A list of wallet addresses to inspect in batch.
limit	Integer	20	No	Number of active wallets to discover (1 to 200), or max transaction records per lookup.
filterContracts	Boolean	true	No	For EVM chains: filters out smart contracts to only return real user wallets (EOAs).
includeTransactions	Boolean	true	No	Attach recent transaction details (hash, block, timestamp, direction) to each record.
customRpcUrl	String	null	No	Optional private RPC endpoint (e.g. Infura, Alchemy, QuickNode). If omitted, public nodes are used automatically.
