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.

Labeling a wallet is good. 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.

• Move 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.

No more guessing. No more scraping. Just plug into the Chainbase Blockchain Address Labeling API and unlock:

• 📦 Entity-level metadata

• 🔗 Linked wallet groupings

• 🧩 Context-rich on-chain intelligence
