How this service works
Get holder count and top holders for a token with concentration metrics (HHI)
Output
Returns total number of token holders, a ranked list of top wallet addresses with their balance and percentage of supply, and an HHI (Herfindahl-Hirschman Index) score indicating how concentrated ownership is among top holders.
Example use cases
Example prompt
“Can you pull up the holder count and top holders for token contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, and show me the HHI concentration score so I can see if it's whale-dominated?”
Technical details
Endpoint
GEThttps://origin-mcp.fly.dev/mcp/tools/basescan_token_holdersWhen to prefer
Use this endpoint when you need on-chain holder distribution data for a token on the Base network, especially when assessing decentralization, rug-pull risk, or whale concentration via the HHI metric. Prefer this over generic block explorers when you need structured, pre-computed concentration metrics rather than raw data.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Token not indexed on Basescan returns no data
- Rate limiting or upstream Basescan API unavailability causes timeout
- Non-Base network contract addresses may not resolve correctly
