Nansen in Action
Follow Flow of Funds
50M+ labeled wallets give you the full context you need to understand the flow of ETH, stablecoins, and tokens. With Nansen you get an executive summary of where funds are moving. And if you want details, you can trace transactions down to the most granular level.
Track Token Traction
Nansen tracks exchanges, token teams, and funds, which means you can see exactly which entities are accumulating - or selling off - a specific token. Token metrics on usage, engagement, and liquidity are available so you can make informed decisions before investing in a new token.
Discover Dynamics of Dapps
With labels on more than 80% of all smart contracts ever deployed on Ethereum, you get a completely different perspective on usage of the Ethereum blockchain.
Analyze Anonymous Addresses
On-chain activity can reveal a lot about an address - when presented the right way. Nansen gives you the tools to investigate wallets that may otherwise be unknown. The combination of on-chain data and labeled neighbouring addresses is incredibly powerful.

From time to time, we may release non-personally-identifying information in the aggregate, e.g., by publishing a report on trends in the usage of our website. We also collect potentially personally-identifying information like email addresses for newsletters and logged-in services.
GATHERING OF PERSONALLY-IDENTIFYING INFORMATION
Certain visitors to our website choose to interact with Nansen in ways that require us to gather personally-identifying information.
The amount and type of information that Nansen gathers depends on the nature of the interaction. For example, we ask visitors who sign up to become users of our service to provide an email address.

What exactly is Nansen?
Nansen is an analytics platform for blockchain, which combines on-chain data with a massive and constantly growing database containing millions of wallet labels.
Customers use Nansen to access this data via user-friendly dashboards, direct SQL queries, or APIs.
Why did you build Nansen?
After years of working with blockchain data, we found that many of our clients wanted the same thing:
to know more about the wallets that are transacting on-chain.
So we started building Nansen in 2019 to address this need, and have quickly become a leading provider of data and analytics for Ethereum.
How do you get the wallet labels?
Our labels come from a variety of sources, including:
HeuristicsSmart-contract parsing and analysisInvestigations and research by our teamUser submissionsWeb scrapingMachine learning
... and crucially the interplay between all of these sources.
More than 99% of our labels are algorithmically inferred.
We aim for extremely high precision, meaning we'd rather not label an address than label it incorrectly.
One key thing to realize is that there is a very strong network effect in adding wallet labels. If we know that wallet X is of type A, and wallet Y is of type B, then if wallet Z interacts with X and Y in a certain way, we can sometimes infer that Z is of type C.
The consequence is that every wallet label we add to our platform can help us infer even more wallet labels.
For the on-chain data itself, we rely heavily on the open source project Ethereum ETL. The main contributors to Ethereum ETL are members of the Nansen core team.
What are some examples of wallet labels included in Nansen?
We include a wide range of types of labels in our platform. The two main ones are entities and categories. An entitity might be an exchange like Binance, or a fund like Placeholder. A category might be "Dex Trader" or "ETH ICO Participant".
What about privacy?
This is a common question, and the first thing to make clear is that we do not focus on personal individuals in our wallet labels.
One important source of data for Nansen is the blockchain itself. It's important to understand that blockchains are public and immutable. We have no control of what users decide to publish on them.
A relevant example is the Ethereum Name Service (ENS), which lets users purchase a human-readable name for their wallet (e.g. nansen.eth). When a wallet registers such a domain (or is involved in the transfer of one), this is recorded forever on the Ethereum blockchain. And since anyone with a computer and an internet connection can run an Ethereum node, the data point representing this transaction is openly available to the world.
Nansen includes information about ENS ownership of wallets (both past and present), and in some cases this might be revealing of an association between a private individual and a wallet.
So while we could remove data points potentially revealing personal identities from our platform, we think it's better that they're made aware that this information is already in the public domain - accessible to anyone.
We are committed to educating users of the privacy risks involved in using blockchains.
In some cases, project co-founders, advisors, and otherwise public figures have shared their addresses in the public domain (e.g. in transparency reports, or news articles). In these cases we might add wallet labels with their names, as the information is already in the public domain.
