Output
A ranked list of up to 100 wallet addresses that hold the most of the specified ERC-20 token on the given chain, including their balances or share of supply, ordered from largest to smallest holder.
Example use cases
Whale concentration check for new token
“Can you pull the top 50 holders of the token at 0x6982508145454ce325ddbe47a25d4ec3d2311933 on Ethereum so I can see if any whales are dominating the supply?”
DeFi project due diligence on Base
“I'm evaluating a project on Base — can you get the top 20 holders of their token at 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 so I can check how decentralized the ownership is?”
Arbitrum token holder monitoring
“Fetch the top 30 holders of the token 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum so I can track if any major wallets have changed their positions.”
Technical details
Endpoint
POSThttps://kette.netzhandwerker.de/token/holdersWhen to prefer
Choose this endpoint when you need on-chain holder distribution data for any ERC-20 token across major EVM chains (Ethereum, Base, Arbitrum, Optimism) and want a ranked list of top wallets. It is ideal for DeFi due diligence, whale tracking, and token concentration analysis. Prefer this over generic blockchain explorers when you need programmatic, structured holder data payable via x402 microtransaction.
Side effects
- Invalid or non-ERC-20 contract address returns an error
- Unsupported chain identifier causes a bad request response
- top_n value outside the 10–100 range is rejected
- Contract address not found on the specified chain returns empty or error
- Payment failure via x402 protocol blocks the request
