Common questions about EthScan.app and how it works
EthScan.app is an EVM (Ethereum Virtual Machine) Private Keys Explorer. It allows you to browse through the entire range of possible Ethereum private keys, check wallet balances across multiple EVM-compatible chains, and scan mnemonic phrases for active wallets.
The private keys are calculated mathematically based on the page number you visit. Each page displays 60 private keys. All calculations happen in your browser using JavaScript, meaning no private keys are ever sent to our servers. The total number of possible pages is approximately 10^75 (2^256 / 60).
Yes, all cryptographic operations (key generation, address derivation) are performed locally in your browser. We do not log or store any private keys. However, you should never use any private key you find on this website to store real funds, as they are publicly browsable.
While theoretically possible, the probability is astronomically low. There are 2^256 possible private keys (a 78-digit number). Even checking billions of keys per second for billions of years would only cover an infinitesimally small fraction of all possibilities. This tool is primarily for educational purposes.
We support multiple EVM-compatible chains including Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, zkSync Era, Linea, Scroll, Fantom, and Gnosis. The same private key works across all these chains since they share the same address derivation method.
A mnemonic phrase (also called seed phrase or recovery phrase) is a list of 12 or 24 words that can be used to derive multiple private keys and addresses. It follows the BIP-39 standard. Our Mnemonic Scanner allows you to enter a phrase and check all derived addresses for balances.
A brainwallet converts any text input into a private key by hashing it (typically using SHA-256 or Keccak-256). You can enter any text in the search box, and we will convert it to a private key and navigate to its page. Note: brainwallets are generally considered insecure for storing real funds.
Balance checks use free public RPC endpoints which may have rate limits or temporary downtime. If a balance check fails, try again after a few seconds or select fewer chains. We recommend checking 5 chains at a time for best reliability.
The key generation and address derivation work offline since all calculations happen in your browser. However, balance checking requires an internet connection to query blockchain nodes.
