How this service works

Get Smart Money Holdings Data

Output

An array of token holding records for smart money wallets, each containing: chain, token symbol, token address, total USD value held, number of smart money holders, market cap in USD, token age in days, sector classifications, share of total smart money holdings as a percentage, and 24-hour balance percent change.

Example use cases

Example prompt

“Show me the top 10 tokens by USD value held by Nansen smart money wallets on Ethereum right now, including sector labels and 24-hour balance changes.”

Technical details

Endpoint

GEThttps://api.nansen.ai/api/v1/smart-money/holdings?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to understand what tokens sophisticated or high-signal crypto wallets (Nansen's 'smart money') are holding, ranked by portfolio value or other metrics. Ideal for market intelligence, trend spotting, and identifying which tokens institutional or whale-tier addresses are accumulating. Prefer this over generic on-chain queries when you want Nansen's curated smart money wallet labels applied to holdings aggregation.

Side effects

Invalid or unsupported chain specified — returns error indicating chain not supported by smart money data
Malformed filter parameters for non-selected columns — API rejects with filter validation error
Pagination offset exceeding available results — returns empty data array
Missing or invalid authentication — returns 401/403 unauthorized
Rate limiting exceeded — returns 429 too many requests
Network timeout for large multi-chain queries — partial or no data returned
