What is Entity Labeling? Entity labeling is the process of tagging blockchain wallet addresses with identifying information, such as whether they belong to an exchange, market maker, bot, or known individual, to make raw onchain data more meaningful.
Entity Labeling Explained On its own, a wallet address is just a string of characters, there's no name attached, no context about who or what is behind it. Entity labeling fills in that gap by attaching tags: this address is a known exchange hot wallet, this one is a market maker, this one is a sybil wallet farming an airdrop, this one belongs to a DAO treasury.
Without labels, every wallet looks the same in a dashboard. With labels, a DeFi protocol can tell the difference between a real retail user, an automated bot, and an exchange routing thousands of transactions on behalf of its customers, which changes how every other metric should be read.
What Entity Labeling Means For Audience
Use Case
DeFi protocol and growth teams
Filter out bots, sybils, and exchange wallets to see how many real users are engaging with a product
Data and analytics teams
Segment wallet activity by entity type to build more accurate retention, revenue, and engagement reports
Compliance and risk teams
Identify wallets connected to sanctioned entities, mixers, or known bad actors before they interact with a DeFi protocol
Examples A DeFi protocol filters its active wallet count to exclude labeled exchange wallets, revealing the true number of individual users.
An airdrop team uses entity labels to identify and exclude sybil wallets before distributing tokens.
A risk team flags wallets labeled as connected to sanctioned addresses before allowing a transaction to proceed.
A growth team segments retention curves by entity type to compare behavior between retail wallets and market makers.
FAQs Is entity labeling the same as KYC? No. KYC verifies a real world identity through documents. Entity labeling tags a wallet address with likely categories or known associations based on onchain behavior and public data, without necessarily identifying the person behind it.
How are wallet labels generated? Through a mix of heuristics on transaction patterns, known address lists from exchanges and DeFi protocols, clustering analysis, and manual research.
Can entity labels be wrong? Yes. Labels are inferred, not guaranteed, so they should be treated as a strong signal rather than absolute fact, especially for less common address types.
Why does entity labeling matter for growth metrics? Because raw wallet counts can be inflated by bots, sybils, or exchange wallets routing many users through one address. Labels let teams correct for that and see real user behavior.
Does entity labeling help with fraud detection? Yes. Identifying wallets linked to known exploiters, sybils, or sanctioned entities helps DeFi protocols flag risk before it affects users or compliance.
