# Wallet Labels: How to Identify Who Owns What on the Blockchain *Wallet labels help you identify exchange wallets, smart contracts, whales, and team addresses on block explorers. Learn how to read and use them for on-chain analysis.* By [Onchain Diary](https://paragraph.com/@onchaindiary) · 2026-07-19 security, crypto, onchaindiary --- Every blockchain address looks the same — a random string of characters. But behind each address is an entity: an exchange, a protocol treasury, a market maker, a whale, or an everyday user. Wallet labels are how you tell them apart. What Are Wallet Labels? ----------------------- A wallet label is a human-readable tag attached to a blockchain address. It identifies the entity that controls that address. For example, the address `0x28C6c06298d514Db089934071355E5743bf21d60` is labeled "Binance 14" — it's one of Binance's hot wallets. Labels come from multiple sources: * **Exchange-published addresses.** Major exchanges publish their [hot wallet](https://theonchaindiary.com/glossary/hot-wallet/) and [cold wallet](https://theonchaindiary.com/glossary/cold-wallet/) addresses publicly, so users can verify deposits. * **Smart contract registries.** A [DEX](https://theonchaindiary.com/glossary/dex/) pool contract or [lending protocol](https://theonchaindiary.com/glossary/lending-protocol/) contract is labeled based on its verified source code on Etherscan. * **Community-maintained databases.** Services like Etherscan, Arkham, and Nansen crowdsource labels from users and on-chain sleuths. * **Self-attestation.** Some projects label their own treasury and team wallets via ENS domains or social media. Without labels, you'd need to manually trace transaction patterns to figure out what an address does. Labels do that work for you. Why Labels Matter ----------------- Labels transform raw data into actionable intelligence. Here's what you can do with them: ### 1\. Track Exchange Flows When tokens move from a project's treasury to an exchange's [hot wallet](https://theonchaindiary.com/glossary/hot-wallet/), that's often a sell signal. Labels let you spot this in seconds instead of tracing addresses manually. ### 2\. Identify Smart Money If a [wallet](https://theonchaindiary.com/glossary/wallet/) consistently buys tokens before they pump, labeling that address lets you follow it. Many on-chain analysts maintain watchlists of profitable wallets and get alerted when they move. ### 3\. Verify Team Activity Project teams often hold tokens in [multi-sig wallets](https://theonchaindiary.com/glossary/multi-sig-wallet/). If team tokens are labeled and you see them moving to exchanges right after a cliff unlock, that's worth knowing before you invest. ### 4\. Avoid Counterparty Risk If you're about to interact with a contract and notice the deployer's address has been flagged as a scammer in label databases, you can stop before sending funds. Types of Wallet Labels ---------------------- Label Type Example What It Means CEX Hot Wallet "Binance 14", "Coinbase 4" Exchange operational funds — frequent deposits/withdrawals CEX Cold Wallet "Binance Cold" Exchange reserves — large balances, infrequent movement Smart Contract "Uniswap V2: Router" Protocol contract — verified source code MEV Bot "MEV Bot 0x7ab..." Extracts value from pending transactions — see [MEV](https://theonchaindiary.com/glossary/mev/) Token Deployer "USDC Deployer" Address that deployed a token contract Treasury "Arbitrum Foundation" Project-controlled funds, often [multi-sig](https://theonchaindiary.com/glossary/multi-sig-wallet/) Market Maker "Wintermute Trading" Provides liquidity, executes large trades Whale "Whale 0x3f..." Large individual holder, unlabeled but high balance Smart Money "Smart Money 0x2a..." Profitable trader tracked by analytics platforms How to Find Wallet Labels ------------------------- ### Etherscan (Free) 1. Search any address on [Etherscan](https://etherscan.io/) or any [block explorer](https://theonchaindiary.com/glossary/block-explorer/) 2. Check the "Name Tag" field below the address 3. For contracts, check the "Contract" tab for verified [Solidity](https://theonchaindiary.com/glossary/solidity/) code ### Arkham Intelligence (Free) Arkham's label database is one of the most comprehensive. You can search addresses, see labeled entities, and set alerts when labeled wallets transact. ### Nansen (Paid) Nansen's "Smart Money" labels identify wallets that consistently outperform. It also tags wallets by behavior pattern (e.g., "heavy DEX trader," "NFT collector"). ### Manual Heuristics When an address isn't labeled, you can infer its role: * **High inbound + high outbound volume + interacts with exchange addresses** → likely a market maker or OTC desk * **Large balance + long dormancy + created at genesis** → early adopter or team wallet * **Deploys tokens + adds initial** [**liquidity pool**](https://theonchaindiary.com/glossary/liquidity-pool/) **funding** → token deployer * **Calls MEV functions + interacts with** [**flash loans**](https://theonchaindiary.com/glossary/flash-loan/) → MEV bot Common Label Pitfalls --------------------- **Labels can be wrong or outdated.** An address labeled "Binance" might have been transferred to a private owner. Always cross-check with recent transaction patterns. **Not all exchange addresses are labeled.** Small exchanges and OTC desks often don't publish their addresses. Missing labels ≠ missing risk. **Labels don't reveal the human behind the address.** "Smart Money" means the wallet is profitable, not that you know who operates it. The blockchain is pseudonymous — labels narrow down identity but rarely confirm it. Putting Labels to Work ---------------------- The practical workflow: 1. **Identify the deployer** of a token you're researching 2. **Check the deployer's recent transactions** — are they sending to exchange wallets? 3. **Look at the token's top holders** — what percentage sits in exchange wallets vs. [non-custodial wallets](https://theonchaindiary.com/glossary/non-custodial-wallet/)? 4. **Check if team/treasury wallets** are labeled and whether [token vesting](https://theonchaindiary.com/glossary/token-vesting/) unlocks are approaching 5. **Monitor labeled wallets** using alerts so you're notified before major moves For a deeper dive into following specific wallets, see our guide on [how to track whale wallets](https://theonchaindiary.com/articles/how-to-track-whale-wallets/).
