You can look up transactions, addresses, blocks, and verified contract code.
Checking a transaction hash independently verifies its real status.
Always use the explorer matching the correct network.

What a block explorer is

A block explorer is a website that lets anyone search and view the public data recorded on a specific blockchain — transactions, blocks, wallet addresses, and (for smart-contract platforms) contract activity.

What you can look up

A specific transaction, by its transaction hash (ID), to check its status and details.
A wallet address, to view its current balance and full transaction history.
A specific block, to see everything included in it and when it was added.
A smart contract's verified source code, if the contract has been published and verified.

Practically verifying a transaction

After sending or receiving a transaction, pasting its transaction hash into a block explorer lets you independently confirm its actual status (pending, confirmed, or failed) and details — a genuinely useful check rather than relying solely on what a wallet interface reports.

In practice

Use the explorer that matches the correct network

Different blockchains have their own separate block explorers. Checking a transaction hash on the wrong network's explorer will simply show no result — always confirm you're using the explorer for the specific network the transaction actually occurred on.
