How this service works
Top holders of an ERC-20 token with labels, balances and share of supply plus top 1, 5, 10 and 20 concentration and a concentration level from Blockscout
Output
A JSON object containing: the queried chain and token metadata, an array of top holders with wallet addresses, labels (e.g. exchange names), balances, and percent of supply; concentration percentages for the top 1, 5, 10, and 20 holders; a categorical concentration level (e.g. high/medium/low); the number of holders returned; and an optional note providing context.
Example use cases
Pre-investment whale risk check
“Before I buy into this token, can you look up the top 10 holders of 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Ethereum and tell me what share of supply the top 5 control? I want to know if it's whale-heavy.”
DeFi protocol governance audit
“Can you check the token holder concentration for the Uniswap governance token at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Ethereum — specifically how much supply the top 20 wallets hold and what the concentration level is?”
New token launch decentralization check
“I'm reviewing a new token on Base at address 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — can you get me the top 5 holders, their share of supply, and tell me whether the concentration level looks healthy or concerning?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/token-holders?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-chain ERC-20 holder concentration data including labeled wallet identities, supply share breakdowns, and a pre-computed concentration level across major EVM chains (Ethereum, Base, Optimism, Arbitrum, Polygon, Gnosis). Prefer it over raw blockchain RPC calls when you need enriched labels and aggregated concentration metrics in a single call without writing custom Blockscout queries.
Side effects
- Invalid or non-contract token address returns an error or empty result
- Unsupported chain name causes a 400 or unrecognized parameter response
- Token with very few holders may return fewer results than requested
- Blockscout data unavailability for a given chain may produce stale or missing data
- Top parameter outside 1-50 range may be rejected or clamped to default
