Strengths and weaknesses

In its favour

Best commercial wallet-labelling applied to NFT flows
Wash-trade filtering with a published approach
Strong alerting on wallet and collection activity

Against it

Expensive relative to what individual collectors extract
Label accuracy degrades on older addresses

Attribution is the product

Knowing that a collection's floor is being swept by three wallets tied to one entity is a different fact from knowing the floor moved. Nansen's labelled dataset is the deepest commercially available, and applied to NFT flows it turns anonymous activity into something you can reason about. It also filters wash trading with a documented approach.

The verification gap

Labels are proprietary and cannot be reproduced by a third party. The transactions beneath them are public and checkable; the attribution on top is a vendor judgement, and older addresses in particular can carry stale labels. Any analysis you publish inherits that dependency, which is worth stating when you publish it.

Price and coverage

Major EVM chains plus Solana, weighted towards larger markets, with a limited free tier and the NFT modules in paid plans at published prices. Exports exist on paid plans; the labels themselves do not travel.

Who it suits

Professional desks trading NFT flow. For a collector deciding on one purchase, free tools plus a block explorer answer the same questions well enough.

How to use it responsibly

Check the underlying transactions when a label carries the weight of your conclusion, and be sceptical of attributions on addresses dormant for years. A label is evidence with a name attached, not a fact.

Frequently asked questions

Is Nansen worth it for NFT trading?+

For desks trading on flow, its labelled-wallet coverage has no free equivalent. For individual collectors, the price is hard to justify against free alternatives plus a block explorer.

Can Nansen's NFT labels be verified?+

No. They are proprietary and cannot be reproduced independently, and labels on older addresses can be stale. The underlying transactions are verifiable on-chain.

Does Nansen filter wash trading?+

Yes, with a documented approach, which is why its volume figures are lower and more useful than raw marketplace totals.

How to read these tables

No paid placement. Nobody buys a position, a score or a mention. We take no affiliate commission on any link in this section, and operators do not see their score before it publishes.

Scores are read from the record. Each one is derived from the fact printed beside it — a published attestation, a contract, a register entry, an incident report — against bands that describe evidentiary states. Facts age: each table carries the date it was last verified, and this is not an audit.

Nothing here is financial advice. Crypto services fail, change terms and withdraw from markets without notice. Verify anything that matters directly with the provider, and tell us when we get something wrong.
