Maintains a database of 300M+ labeled wallets (exchanges, MM, known whales, smart money). When those wallets move funds, Nansen surfaces it. Used by hedge funds and serious traders.

Most valuable features

1. Smart Money tab

Shows aggregate activity of profitable wallets (Nansen's own metric). If 'Smart Money' is accumulating a token, pay attention.

2. Token God Mode

For any token: holder distribution, top holders' activity, exchange flows. Best paid feature.

3. Wallet Profiler

Paste any address → see net worth, holdings, winning trades, losing trades. Useful for evaluating 'influencer' actual track records.

Free tier (meh)

The free tier is more of a sales demo. Real value starts at $150/month (Pioneer) which is a lot for hobbyists. Better for teams.

The smart money caveat

'Smart money' is defined by past performance. Past performance does not predict future performance. Nansen smart money has been wrong on many occasions.
