Arkham vs Nansen
Both label wallets to reveal who's behind an on-chain move. Arkham crowdsources addresses via a token bounty exchange; Nansen relies on its own engine.

Verdict
Arkham and Nansen do the same core job — tag anonymous blockchain addresses with real-world identity so you can follow what a specific exchange, fund or "smart money" wallet is doing rather than staring at a hash — but they get there differently. Nansen relies entirely on its own in-house attribution engine, layered under a conventional tiered subscription that gates deeper labels, more chains and API access. Arkham's core explorer and entity search are free to use, and its distinguishing feature is the Intel Exchange, a marketplace where users post bounties in Arkham's own ARKM token for identifying specific unlabeled addresses — crowdsourcing attribution the in-house engine hasn't caught yet, rather than relying solely on a closed team.
Choose Arkham if
- You want free access to core wallet-search and entity-attribution tools without a subscription commitment.
- You're chasing attribution on a specific, currently-unidentified address and are willing to use (or fund) the bounty exchange to get there.
- You're comfortable with a token-based incentive model rather than a fixed monthly price for deeper access.
Choose Nansen if
- You want a conventional subscription with predictable tiers gating label depth, chain coverage and API access.
- You're a trader or fund tracking labeled "smart money" wallet activity in real time and want dashboards and alerts built specifically for that workflow.
- You prefer attribution sourced from one accountable in-house engine over a crowdsourced marketplace.
The honest caveat
Wallet-labeling accuracy on both platforms depends on ongoing attribution work, and neither publishes a methodology detailed enough to fully audit label confidence — treat a label as a strong lead, not proof, especially for newer or less-active addresses. Neither product should be confused with compliance-grade attribution: for AML and sanctions-screening use cases with a legal or regulatory obligation behind them, see Chainalysis instead, covered in choosing a crypto analytics tool.
