An on-chain analytics platform built on a large labelled-address database, used to track wallet cohorts and follow so-called smart money across chains.
Our assessment
Nansen's product is its labels. It maintains attribution across hundreds of millions of addresses, which turns an anonymous ledger into something readable: this cluster is a fund, this one is an exchange, this one has been early to several profitable positions. Pricing runs from $150 a month at the Pioneer tier to $1,500 at Alpha.
Labels are the moat and the weakness
A labelled address is an inference, not a fact, and inferences degrade. Entities rotate wallets, use intermediaries and deliberately obscure activity — the more valuable a label becomes, the more incentive there is to defeat it. The data is genuinely useful and should be read as a well-informed estimate rather than a registry.
What smart money following does to you
Copying wallets that have been right before is a strategy with a specific flaw: you see the entry after it happened, without the thesis, the position size or the exit plan. Funds also trade against retail flow they know is watching them. Use the data to generate questions, not to place orders.
The price is the filter
At $150 to $1,500 a month, this is a professional tool, and the return has to come from decisions the data actually changed. Most individual traders would gain more from cheaper tools used properly. Eight cost and terms indicators found nothing retrievable at conventional public addresses, with fourteen failures overall.
Who it suits
Nansen fits funds, professional traders and researchers who need cross-chain wallet attribution and will act on it systematically. Individuals should start with free tools — DefiLlama, Arkham's free exploration, Glassnode's newsletter — before paying professional rates.
Frequently asked
Does this score mean Nansen is trustworthy?
No. It measures what is published and reachable before use: the service, its terms and its documentation. Custody, routing and corporate structure are not tested by us.
Why do all providers score zero on corporate entity?
Because this class of service rarely publishes it. The indicator is identical for every provider in the category, so the comparison stays fair.
Are rates or spreads compared here?
No. Verifying quoted rates requires live transactions, which we do not perform. The rubric covers disclosure, not execution.
