Free Multi-Chain Block Explorer

The Multi-Chain Block Explorer is a free online tool that open any transaction hash, block number, wallet address, or contract in 15+ blockchain explorers at once. supports ethereum, bsc, polygon, solana, bitcoin, and more.. It runs entirely in your browser with no installation or sign-up needed.

15 chains: Ethereum, BSC, Polygon, Arbitrum, Optimism, Avalanche, Fantom, Solana, Bitcoin, Tron, Cronos, Base, zkSync, Linea, and Scroll.

Yes — paste any address, transaction hash, or block number to generate links to all 15 explorers simultaneously.

Yes, completely free.

Absolutely. The Multi-Chain Block Explorer processes everything client-side in your browser. No data is uploaded to or stored on any server. Your content remains private on your device at all times.

Yes, the Multi-Chain Block Explorer is fully responsive and works on smartphones and tablets. You can use it on any device with a modern web browser -- no app download required.

No account or registration is needed. Simply open the Multi-Chain Block Explorer in your browser and start using it immediately. There are no sign-up walls or usage restrictions.

Simply enter your input in the provided field, adjust any settings to your preference, and the tool will process it instantly. You can then copy the result to your clipboard or download it.

The Multi-Chain Block Explorer works in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For the best experience, use the latest version of your preferred browser.

It checks the format of what you paste against known patterns and labels the result for you. A transaction hash is a "0x" prefix followed by exactly 64 hexadecimal characters; a wallet or contract address is "0x" followed by exactly 40 hex characters; and a block number is an all-digits value like 19500000. The detected type is shown back to you before any links appear, so you can confirm the tool read your input correctly. This matters because each explorer uses a different URL path for a transaction, an address, and a block, and pasting the wrong type would otherwise send you to a dead page. Paste any single value and the tool builds the right kind of link for all 15 chains automatically — no need to tell it what you have.

Yes. Ethereum, BSC, Polygon, Arbitrum, and the other EVM-compatible chains share the same address format, so a single "0x" address is technically valid on every one of them — and people routinely reuse one address across networks. The same is true of deployed contracts: identical bytecode can sit at the same address on several chains. That is exactly why a one-input value tells you nothing about which network holds the activity. This tool turns that ambiguity into a quick check: paste the address once and it generates a direct link to that address page on all 15 explorers at the same time, so you can click across Etherscan, BscScan, PolygonScan, and the rest to find which chain actually shows a balance or transactions, instead of retyping the address into each site.

It builds links rather than fetching data. The tool is a fast, accurate URL builder: it constructs the correct explorer address using each network's real path structure, then opens the official third-party explorer — Etherscan, BscScan, Solscan, and so on — in a new browser tab when you click a card. The actual lookup of balances, confirmations, token transfers, and contract source happens on those explorers, not here. This design keeps it instant and private, since your input is only used on your device to assemble the links and is never sent to a server. So treat the cards as a shortcut to the canonical explorer for each chain. Paste a hash or address, then click straight through to the live record on whichever network you need.

Chain IDs are an EVM concept. A chain ID is a number that identifies an Ethereum-compatible network — Ethereum is 1, BSC is 56, Polygon is 137, Base is 8453, and Arbitrum is 42161 — and it exists mainly to stop a signed transaction on one EVM chain from being replayed on another. Bitcoin, Solana, and Tron are not EVM chains: they use entirely different address formats and transaction models, so they have no EVM chain ID and the tool marks them as not applicable rather than inventing a number. The explorers still work normally; only the numeric ID column is blank for them. The reference grid lists each supported chain's ID where one applies, so paste your input and use it to confirm you are looking at the right network before clicking through.

Yes. Every card links to the canonical, official explorer for its chain — Etherscan for Ethereum, BscScan for BSC, Solscan for Solana, Blockchain.com for Bitcoin, and so on — using each site's documented URL structure, so you land on the genuine record rather than a lookalike domain. The links open in a new tab with secure rel="noopener noreferrer" attributes, which prevents the opened page from gaining scripting access back to this tab. Building links from one verified input also removes the typo risk of entering a long hash or address into 15 sites by hand, where a single wrong character quietly sends you to the wrong page. Always confirm the domain in your address bar after clicking. Paste your value here to get clean, correctly formed links to all 15 explorers in one click.
