Ethereum Block Explorer
Search Ethereum addresses, transactions, blocks, and ERC-20 tokens for free.
Alltoscan is a free Ethereum block explorer that lets you look up any address, transaction, block, or ERC-20 token on the Ethereum mainnet (chain ID 1). Search a wallet to see its ETH balance, token holdings, and full transaction history.
Unlike single-chain explorers, Alltoscan shows the same wallet across nine blockchains, so you can follow funds that move between Ethereum and other EVM networks without switching tools.
What you can do with the Ethereum explorer
- Look up any Ethereum wallet address to see its ETH balance, token holdings, and transaction history.
- Inspect a transaction by hash to view its status, value, sender, recipient, and fees.
- Browse blocks on Ethereum and the transactions they contain.
- Open a token page to review its details and holders.
- Track the same address across all nine chains Alltoscan supports, not just Ethereum.
