Free multi-chain crypto address profiler
Look up any cryptocurrency address: balance, transaction count, recent transactions, ENS reverse-resolution (for Ethereum), and direct links to ten or more block explorers per chain. Auto-detects whether the address is Bitcoin, Ethereum/EVM, Monero, Litecoin, Dogecoin, or Solana.
For OSINT investigations: pair this profiler with the OFAC Crypto Checker for sanctions screening, and use the linked clustering tools (WalletExplorer, Breadcrumbs) for fund-flow analysis. ENS reverse-resolution is a high-leverage pivot — when an EVM address has set a primary ENS name, the owner has tied an identity to that wallet.
All lookups use free public APIs that allow CORS: Blockstream Esplora for Bitcoin, ethereum.publicnode.com for Ethereum mainnet RPC, ensideas for ENS resolution. No keys, no signups, no rate-limits beyond the upstream provider's defaults.
Frequently asked questions
Which chains are supported with live lookups?
Bitcoin (Blockstream Esplora API) and Ethereum mainnet (public JSON-RPC). For Monero, Litecoin, Dogecoin, Solana and 40+ other chains the page auto-detects the address format and links you out to the relevant explorers (Blockchair, Solscan, XMRChain, etc.).
Is my query sent anywhere?
For Bitcoin: the address is sent to blockstream.info over HTTPS. For Ethereum: the address goes to ethereum.publicnode.com public RPC. ENS resolution uses api.ensideas.com. None of these require a key. Max Intel never sees the query.
How do I check if an address is sanctioned?
Use the dedicated
OFAC Crypto Checker page — it bundles the OFAC SDN-list of sanctioned crypto addresses and does instant offline lookup.
How do I trace funds across multiple addresses (clustering)?
For Bitcoin: WalletExplorer (linked above) and Breadcrumbs.app provide free clustering analysis. For Ethereum: DeBank shows tokens and DeFi positions; Etherscan's "address tag" data identifies known entities. Serious clustering work uses Chainalysis Reactor or TRM Labs (commercial) but the free explorers cover most OSINT needs.
What is ENS and why does the reverse-resolve matter?
Ethereum Name Service maps human-readable names like vitalik.eth to Ethereum addresses. The reverse-resolution finds the canonical name an address has set as its primary. This is OPSEC-relevant: if an address has set a public ENS name, the owner has explicitly tied their identity to that wallet.
