Can you recommend a wallet tagging tool for detecting whale activity and smart-money flows in DeFi?

Yes — here are some solid wallet-tagging / wallet-tracking tools for spotting whale activity and smart-money flows in DeFi:

Best options

1. Nansen

   • One of the strongest choices for wallet labeling, smart-money tracking, whale alerts, and fund-flow analysis.
   • Good for seeing what smart wallets are buying, holding, or exiting.
   • Best if you want a polished analytics platform.

2. Arkham

   • Strong for wallet entity tagging and linking wallets to known individuals, funds, protocols, or organizations.
   • Useful for tracing on-chain activity and identifying clusters of related wallets.
   • Good if your focus is attribution and wallet intel.

3. DeBank

   • Great for tracking DeFi portfolios and wallet behavior across chains.
   • Less of a dedicated intelligence platform than Nansen/Arkham, but useful for monitoring smart wallets you already know.

4. Dune

   • Not a tagging tool by itself, but powerful if you want to build custom dashboards for whale tracking and smart-money flows.
   • Best for analysts who want flexibility.

5. Breadcrumbs / Bubblemaps

   • Helpful for visualizing wallet clusters and token distribution.
   • Good for spotting coordinated wallets, insider-like patterns, or concentration risk.

My quick recommendation

• For smartest all-around DeFi wallet intelligence: Nansen
• For wallet attribution / entity labeling: Arkham
• For custom analysis: Dune

If you want, I can also give you:

• a free vs paid comparison
• the best tool by chain (Ethereum, Solana, Base, etc.)
• or a workflow to identify smart-money wallets and copy their trades.
