}'Over 2 billion address labels
Exchanges, funds, mixers, sanctioned wallets and more — the entities and risk tags investigators and compliance teams actually search for.
Thousands of entities, named
Exchanges, funds, market makers, protocols and threat actors — resolved from raw addresses to names your team already recognizes.
Labeling addresses yourself is a research project
In-house means scraping explorer label clouds, reconciling vendor lists, and re-checking sanction feeds on every chain. ChainLabel runs that pipeline and serves it from one endpoint.
Scattered sources
Explorer tags, vendor CSVs and sanction feeds — every source in a different format, every chain a separate silo.
Goes stale fast
New designations and rotated wallets mean yesterday's export is already wrong — and a stale label is a compliance miss.
Doesn't scale
Manual, one-address-at-a-time lookups collapse the moment you have thousands of addresses to attribute.
Everything you need to label addresses
One product, one endpoint. The data that powers compliance screening, fund tracing and on-chain analytics — served the way developers actually want it.
Entity & owner labels
Resolve an address to the entity behind it — Binance, Coinbase, OKX, Deribit, and thousands more — plus the specific wallet role.
Risk & sanction tags
Centralized Exchange, Hot/Cold Wallet, Mixer, Bridge, OFAC/UK sanctioned, high-transacting — the signals compliance teams screen for.
Multi-chain, one call
Ethereum, BSC, Base, Arbitrum, Polygon, Bitcoin, Tron, Solana and more. One row per network, or filter to a single chain.
Refreshed every day
Every label is re-checked through our pipelines daily, so attribution stays current — you are never acting on a stale, year-old export.
One endpoint, real docs
A single POST endpoint with a Bearer key. Predictable schema, structured errors, and copy-paste examples in curl, JS and Python.

Address entity & risk labels
Who owns this address?
Resolve the entity, wallet role and network name behind any address — the label users recognize.

"network": "ETHEREUM",
"title": "Binance: Hot Wallet",
"entity_name": "Binance",
"label_name": "Hot Wallet",

}Is it risky or notable?
Every label ships with the tags analysts screen on — exchange, mixer, bridge, sanctioned, and more.

Each address comes back tagged across four dimensions — so you can filter, screen and attribute without guessing what a label means.
