# Instantly Identity Data with Labeling API **Published by:** [Chainbase Network - Blog](https://blog.chainbase.com/) **Published on:** 2025-03-24 **URL:** https://blog.chainbase.com/chainbase-api-update-introducing-blockchain-address-labels ## Content Struggling to decode complex wallet addresses? Tired of squinting at raw on-chain data to guess who’s who? Chainbase’s Blockchain Address Labeling API is just what you need. The new Blockchain Address Labeling API will assist you in identifying the on-chain identity of addresses. No more blind spots—just clean, structured, and instantly usable identity data for your dApps, dashboards, and analytics tools. Below is a sample response illustrating how this API works. Now you know: it’s a hot wallet, early SHIRO holder, and connected to a CEX.{ "code": 0, "message": "ok", "data": { "0x9642b23ed1e01df1092b92641051881a322f5d4e": [ { "category": "cex", "tags": [ "MEXC Hot Wallet" ] }, { "category": "early-token-holder", "tags": [ "Early SHIRO Holder" ] }, { "category": "ethereum-first-funder", "tags": [ "Ethereum First Funder: 0xafBc2518f9e0267443983d1BDDf6e32c3e07dc45" ] }, { "category": "hot-wallet", "tags": [ "Hot Wallet" ] }, { "category": "tokenized-eth2-staker", "tags": [ "Tokenized ETH2 Staker" ] } ] } }Why Developers Love ItDecode counterparties on the fly: Enrich every transaction with who’s behind the address.Avoid costly mistakes: Labels help users avoid sending funds to shady or incorrect addresses.Faster builds: Whether you're creating explorers, dashboards, or DeFi monitors, this saves hours of manual mapping.Plug-and-play: Query once, get labeled data instantly—no need to build your own tagging system.2.3M+ Labeled Addresses & CountingWe’ve got the broadest label coverage across all major blockchains:EthereumBNB Smart Chain (BSC)PolygonBaseOptimismArbitrum…and many more!20+ Label CategoriesWe support a broad range of address categories, such as NFT Marketplaces, DEXs, CEXs, Meme Coins, DeFi Protocols, and Lending Platforms.

Knowing who is behind it? That’s a game-changer. While address labels help you classify wallets (CEX, DeFi, etc.), they don't always reveal the actual entity controlling the address. That’s why Chainbase goes further—with Entity Labels.🧠 Entity Labels connect wallets to real-world entities such Binance, Bybit, etc., giving you a clearer picture of on-chain behavior across protocols, organizations, or institutions.Why It MattersMove from addresses to identities: Know if you're interacting with Binance, a DAO treasury, or a known attacker.Cut through wallet complexity: Many entities operate dozens—or thousands—of addresses. We group them for you.Build smarter analytics & security tools: Spot suspicious actors, flag high-risk counterparties, or track real-time institutional flows.Clean, Structured, Dev-ReadyNo more guessing. No more scraping.
