What is a multichain block explorer?

A multichain block explorer is a single tool for reading data from several blockchains at once. Where a traditional explorer covers one network, a multichain explorer lets you search the same address, transaction, block, or token across many chains without switching sites or learning a different interface for each.

Why it matters

Crypto activity rarely stays on one chain. Funds bridge from Ethereum to Layer 2 networks like Arbitrum, Base, and Optimism, or move to BNB Smart Chain, Polygon, Avalanche, and others. Following that activity with single-chain explorers means juggling many tabs. A multichain explorer keeps the whole picture in one place.

What you can look up

On Alltoscan you can check a wallet’s native balance and token holdings, inspect a transaction by its hash, browse blocks and the transactions inside them, and open token pages — on any of the nine supported chains: Ethereum, BNB Smart Chain, Polygon, Avalanche, Arbitrum, Optimism, Base, Fantom, and ZKFair.

Alltoscan is free and needs no account. To get started, head to the home page and search, or browse the supported chains.
