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.

Nansen is a service by Nansen Limited, a Hong Kong company.

We have a few fundamental principles that we follow:

We don’t ask you for personal information unless we truly need it.We don’t share your personal information with anyone except to develop our products, protect our rights, or comply with the law.We don’t store personal information on our servers unless required for the on-going operation of our service.It is our policy to respect your privacy regarding any information we may collect while operating our service.
Like most website operators, we collect non-personally-identifying information of the sort that web browsers and servers typically make available, such as the browser type, language preference, referring site, and the date and time of each visitor request.

Our purpose in collecting non-personally identifying information is to better understand how visitors use our website.

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.

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. We do this simply because it is the most convenient way to persist a user account over time, while having the possibility to communicate with you as a user (via email).

When signing up to Nansen as a user, you are automatically enrolled into our email communication, but you can unsubscribe at any time by clicking the "Unsubscribe" button in our emails.

When users are logged in, we also save the information given to us as necessary for the service to provide value. Nansen collects information only insofar as is necessary or appropriate to fulfill the purpose of the visitor’s interaction with Nansen. Nansen does not disclose personally-identifying information other than as described below. Visitors can always refuse to supply personally-identifying information, with the caveat that it may prevent them from engaging in certain website-related activities.

Nansen may collect statistics about the behavior of visitors and users of its websites. For instance, Nansen may monitor the most popular dashboards or queries on Nansen. Nansen may display this information publicly or provide it to others. However, Nansen does not disclose personally-identifying information other than as described below.

Nansen discloses potentially personally-identifying and personally-identifying information only to those of its employees, contractors and affiliated organizations that:
(i) need to know that information in order to process it on Nansen behalf or to provide services available at Nansen websites, and
(ii) that have agreed not to disclose it to others.

Some of those employees, contractors and affiliated organizations may be located outside of your home country; by using Nansen, you consent to the transfer of such information to them. Nansen will not rent or sell potentially personally-identifying and personally-identifying information to anyone.

Other than to its employees, contractors and affiliated organizations, as described above, Nansen discloses potentially personally-identifying and personally-identifying information only in response to a subpoena, court order or other governmental request, or when Nansen believes in good faith that disclosure is reasonably necessary to protect the property or rights of Nansen, third parties or the public at large.

If you are a registered user of an Nansen website and have supplied your email address, Nansen may occasionally send you an email to tell you about new features, solicit your feedback, or just keep you up to date with what’s going on with Nansen and our products.

Nansen takes all measures reasonably necessary to protect against the unauthorized access, use, alteration or destruction of potentially personally-identifying and personally-identifying information.

Nansen uses cookies to help Nansen identify and track visitors, their usage of Nansen website, and their website access preferences. Nansen visitors who do not wish to have cookies placed on their computers should set their browsers to refuse cookies before using Nansen's websites, with the drawback that certain features of Nansen websites may not function properly without the aid of cookies.

About Nansen

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.

You can also review our privacy policy for information about the privacy of our customers' data.
