Learn everything about Nansen and the most frequently asked questions.
Why is the platform called Nansen?
We named the platform after Fridtjof Nansen who was an explorer, scientist, diplomat, and humanitarian. Our core values for Nansen are: Transparency, Courage, Curiosity, Speed And we think Fridtjof Nansen is a human embodiment of these values.
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?
We use a variety of methods to label wallets, including: Heuristics and algorithms, Smart-contract parsing and analysis, Investigations and research by our team, User submissions and more. 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 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.
Payment / Billing Questions
Can I cancel my plan at any time?
If paying with credit card, you will not be charged if you cancel your plan before the next billing cycle. If you cancel during your subscription period, you will continue to enjoy unlimited access to your account until the end of your subscription period. We will not issue a refund.
If paying with crypto, your subscription will not renew automatically at the end of your current subscription period and you will not be charged unless you purchase another subscription.
Can I upgrade my plan at any time?
If you'd like to upgrade your plan, just make payment for a different tier and you'll get an email on how to activate your account.
Does the trial auto-renew?
No, the trial does NOT renew automatically. At the end of your trial, you will be switched to Nansen Lite (Free) plan.
I purchased the trial a 2nd time but now I don't have access, what should I do?
The total value of NFT portfolio based on 24h median price (7d if no sales).
What is "Liquidity Risk"?
Liquidity Risk is the risk based off the amount of transactions in the last 7 days.
What is "Liquidity Velocity"?
Liquidity velocity is calculated by contrasting the average number of transactions in the last day with the average for the past week. Low liquidity and a rising velocity would mean that there is a good chance that the NFT could be sold for its estimated price based on the latest median average.
How should I interpret Maker/ Taker?
The Maker is the one who offers the liquidity (or order) first. The Taker takes the offer.
What is the different between minimum price (on Nansen) and minimum price (on Opensea)?
Floor on opensea is lowest listing price, Min on Nansen is lowest sale over 24HR, and can usually also be seen on the scatter graph. Floor is used fairly generally in NFTs to refer to sales or listing.
What's the difference between floor price on OpenSea and min price on Nansen and why are those prices sometimes 'off'?
Floor price on OpenSea is lowest listing price, Min. on Nansen is lowest sale over 24HR, and can usually also be seen on the scatter graph. Floor is used fairly generally in NFTs to refer to sales or listing.

Nansen Connect Questions
What is Nansen Connect?
Nansen Connect is a web3 powered messaging tool. Connect is in beta and offers the following features: • Wallet to wallet messaging using end-to-end encryption • Gated access to communities based on NFT and token holdings • Exclusive Nansen groups based on our advanced labels, such as 'Smart Money', 'Millionaire Club' and 'Airdrop Pro' • Data driven profiles of users including token balances and Nansen labels.
I think I’ve created a duplicate (Lite) account, what do I do?
Existing Nansen users should link their wallet and account via the account management page before continuing to Connect. If you have created a duplicate ‘Lite’ account you can follow the below steps to resolve.
1. Go to https://pro.nansen.ai/account-management 2. Login to your main account 3. Select 'connect wallet' 4. Sign the ‘signature request’ from Metamask 5. Sign out of Nansen Connect 6. Log back in to Nansen Connect
How is Nansen Connect different from Discord or Blockscan Chat?
The aim of this app is to be web3 first. This means that users are verified before entry to the app via their wallets. Discord allows anyone to enter and is not based on ownership which in turn can lead to increased spam and noise. And, unlike other web3 connected messaging apps, Nansen Connect is end-to-end encrypted for direct messaging.
Who can I message?
You are able to send a message to any wallet that exists on the ethereum blockchain. However, those wallets will not see messages until they log into Nansen Connect.
If anyone can message me, how can I prevent spam?
You will have the ability to deny or accept any new message request that comes into your inbox. On launch of the Nansen Connect admin and moderation will be manually processed. Nansen will be building up this support as the rollout continues. Please watch this space.
What information is synchronised on blockchain?
While we sync on-chain data to build web3 identity and verify eligibility criteria, all messages sent are stored off-chain.
Are my messages safe and secure?
We have taken many measures to create a safe environment for this community. Direct Messages between two individual wallets are end-to-end encrypted and all users of Nansen Connect are verified before entry to the app via their wallets
How are my messages encrypted and stored?
Direct messages on Connect are end-to-end encrypted. Encryption and decryption happen locally in your browser using an encryption key that is also stored locally. No third party including our servers are able to access a message in a decrypted format.
Why does Metamask ask that I sign two messages?
This creates a link between your Metamask wallet and the Nansen Connect app. Signing the first message allows Nansen verify your ownership of the wallet address and authenticate you in Connect. By signing the second message you are verifying access to your encryption key. No one but you is able to retrieve your encryption keys. This happens entirely off-chain and no transaction happens during this process.
Will I have to always sign two messages on Nansen Connect?
No, you will only have to sign the second message if you:
1. Log out of your account 2. Open Connect in a new browser or a new device 3. Open Connect in an incognito mode
How can I create my own community?
You can request a new community by adding a request here. We are working on an update enabling anyone to create a new community on Connect.
My NFTs are stored in a hardware wallet, can I join Nansen Connect?
Our new encryption method allows you to join your favourite communities on Nansen Connect with your hardware wallet. We will also expand support to other wallet providers in the future.
I've just bought a listed NFT but can't access the app?
Please wait a few minutes to allow the system to update. We are working to make this instant in the future.
I have the tokens in my wallet, but I can’t join the community?
To join a ERC20 community, you need to make sure that you have the minimum number of tokens required to join a channel.
Why is a channel read-only?
Depending on the channel and its guidelines there may be some restrictions. For example, in the ‘Announcement’ channels only admins can post messages to the wider community. Whereas in a group that you are a full member of, you can post images, text, links, and emojis.
How do I enable Browser Notifications?
You can enable notifications in the Settings menu. This can be accessed by clicking on your PFP.
Note: You may have to enable notifications in your computer if you’re using Mac. You can click on this link and follow the steps.
