A blockchain explorer is a free website that lets you search and verify any transaction, address, or block on a public blockchain — like a search engine for the chain. This guide explains what you can look up and how to check a transaction in seconds.
What a blockchain explorer is
A blockchain explorer is a free web tool that shows everything recorded on a public blockchain: transactions, wallet addresses, and blocks. Because public chains are transparent, anyone can look this data up — no account required. Popular explorers include Etherscan (Ethereum and EVM chains), Mempool.space (Bitcoin), and Solscan (Solana).
What you can look up
Paste a transaction hash or an address into the search bar, and the explorer lays out the on-chain details clearly:
How to check a transaction
- Open the explorer for the right network. Etherscan for Ethereum, Mempool.space for Bitcoin — pick the one for the chain your transaction is on. - Paste the transaction hash (TXID). This is a unique identifier — typically 64 hexadecimal characters on Ethereum and Bitcoin — that you drop into the search bar. - Read the result. The explorer shows the status (pending, confirmed, or failed), the sender and recipient, the amount, the network fee, and the block it landed in.
Why it is useful
A blockchain explorer is the simplest way to independently verify what happened on-chain: confirm a transfer arrived, check how many confirmations it has, look up any address's balance and history, or inspect a token contract. The whole process needs no account and is open to anyone.
The bottom line
A blockchain explorer turns public but cryptic on-chain data into something anyone can read and verify. Knowing how to use one is a core skill for moving around crypto safely. To keep learning the fundamentals, follow more from Bitbase Academy.
