What is Ethplorer?
Ethplorer is an Ethereum explorer built around ERC-20 tokens: it shows address portfolios, historical USD balances, token transfers and a rich list of the top 10,000 wallets. It has run since 2016. The free API key allows 2 requests per second and 1,000 per day.
How Ethplorer works
Ethplorer indexes Ethereum with a focus on ERC-20 tokens.
For any address it builds a portfolio view with balance charts, historical balances in USD and per-token transfers, and for each token it shows daily balances, trading volume, operations and price charts in candle or line mode. A rich list ranks the top 10,000 wallets by aggregated USD holdings. Tags and notes you add are stored anonymously in your browser and can be exported or imported as JSON without an account.
The same API endpoints and keys work across sister explorers: api.ethplorer.io for Ethereum, sepolia-api and hoodi-api subdomains for testnets, api.binplorer.com for BNB Chain, api.lineaplorer.build for Linea and api.blastplorer.info for Blast. Methods include getTokenInfo, getAddressInfo, getTxInfo, getAddressHistory, getTopTokenHolders and getTokensNew, and every call takes an apiKey parameter. A Bulk API Monitor is offered for tracking many addresses at once.
How to start with Ethplorer
- Search a token name or address on ethplorer.io with no sign-up, then export an address history with historical prices as a CSV file.
- The Watching service sends email or Telegram alerts for incoming and outgoing transactions on an address.
- For development, the API wiki offers the shared key freekey; for a real project you sign up and create a personal key in the API Panel.
- Ethplorer asks for one key per project and says creating several keys to get around limits violates its policy.
Ethplorer fees and limits
The API wiki calls the service free, with one condition: you must reference the Ethplorer API on your site or use Ethplorer's direct links to transactions and addresses. freekey is limited to 2 requests per second, 20 per minute, 100 per hour, 1,000 per day and 3,000 per week, with at most 100 records per response and 30 days of history. A free personal key raises this to 10 requests per second, up to 1,000 records per response and one year of history.
Risks to know before using Ethplorer
- Ethplorer is a read-only explorer and never takes custody of funds.
- The API wiki states there is no warranty for the data it returns, so check balances used for accounting or tax against a second source. freekey is shared by every developer who uses it and is marked as not recommended for production.
- The Goerli testnet API is listed as deprecated, so older scripts pointing at goerli-api.ethplorer.io need to move to Sepolia or Hoodi.
