Nansen is a paid analytics platform whose core value is wallet labeling. Every wallet is tagged (Binance hot wallet, Vitalik, Uniswap treasury, Jump Trading, Wintermute, etc.). Aggregate labels create "Smart Money" categories.
How labels are made
Combination of:
- Public disclosures (Etherscan address book).
- Transaction pattern inference (this wallet consistently trades before pumps, label = smart trader).
- Manual research (verified team wallets from projects).
- Data partnerships.
Nansen has ~500M+ addresses labeled across chains.
Smart Money categories
- Smart Money. Historically-profitable trader wallets.
- Smart Money DeFi. Farmers with track record.
- Smart Money NFT. Flippers with above-average returns.
- Fund. Known VC / hedge fund wallets.
What Smart Money signals mean
- Real signal. Aggregate Smart Money accumulating a token is often followed by broader accumulation.
- Not perfect. Some "Smart Money" wallets know they're labeled and can front-run their own moves.
- Lagged. By the time you see it, price often already moved.
