How to Use a Block Explorer

If you have ever sent crypto and then wondered "did it actually arrive?", a block explorer is the tool that answers that question. It is a website that reads a blockchain and shows you what happened, in plain view, for anyone to see.

This guide explains what a block explorer is, what it shows you, and how to check a transaction step by step. It is written in plain English for beginners, with no jargon left undefined.

A block explorer is a website that lets you search and read the records on a blockchain. Think of it as a search engine for one specific blockchain: you type in something you want to find — a transaction, a wallet address, or a block — and it shows you the details.

A blockchain is a public record of every transaction on a network, shared across thousands of computers. That record is open by design, but the raw data is hard to read on its own. A block explorer takes that raw data and presents it in a clear, human-friendly way.

Two things make block explorers useful for everyone. First, they are public — anyone can look up any transaction or address, whether or not they own it. Second, they are free — you do not create an account, log in, or pay a fee to view the data. There are many well-known explorers, and most blockchains have one or more of their own.

A block explorer can show you a lot, but as a beginner you only need to recognise a handful of things. Here are the main ones.

• Transactions. Every transfer of crypto, showing the sending address, the receiving address, the amount, and the date and time.
• Wallet addresses and balances. A wallet address is the public "account number" for a wallet. The explorer shows its current balance and its full history of transactions.
• Confirmations. A confirmation means the network has accepted a transaction into a block. More confirmations means the transaction is more settled and harder to reverse.
• Fees. The network fee paid to process the transaction. Fees change with how busy the network is — our guide to what gas fees are explains why.
• Block details. A block is a batch of confirmed transactions. The explorer shows when each block was created and which transactions it contains.

You do not have to understand every field. For most everyday checks, the transaction and its confirmations are all you will look at.

Checking a transaction is the most common reason people open a block explorer. Here is how to do it.

1. Get the transaction ID (hash). When you send crypto, your wallet or exchange gives you a transaction ID — also called a hash or TxID. It is a long string of letters and numbers. Copy it exactly.
2. Open the explorer for the right blockchain. Each network has its own explorer. A transaction sent on one blockchain will not appear on another blockchain's explorer. If your wallet shows a "view on explorer" link, using that link is the safest way to reach the correct site.
3. Paste the ID into the search box. Paste the transaction ID and search. The explorer will open a page for that exact transaction.
4. Read the status and confirmations. Look for the status — usually shown as "Pending" (still being processed), "Success" or "Confirmed" (gone through), or "Failed" (did not complete). Then check the number of confirmations. Once it shows "Success" with a few confirmations, your transfer has arrived.

Moving funds off an exchange is a common time to do this check. Our guide on how to move crypto from an exchange to a wallet walks through the whole transfer.

You can also look up a wallet address instead of a single transaction. Paste the address into the explorer's search box, and it will show that wallet's current balance and its full list of past transactions.

This is useful for confirming that a payment reached the right address, or for keeping an eye on a wallet you control. Because the data is public, you can check any address — you do not need to own it or log in.

That openness has a privacy side, though. Blockchains are pseudonymous: an address is not directly labelled with your name, but everything it does is visible to anyone forever. If someone links an address to your identity — for example, because you shared it — they can see its whole balance and history. For that reason, treat a wallet address as public information and avoid publishing one that is tied to you.

Once you are comfortable reading an explorer, it becomes a handy everyday tool. Common uses include:

• Confirming a transfer arrived. Check the status and confirmations before you assume a payment failed or worry that funds are lost.
• Verifying a contract or token. An explorer can show details about a token or smart contract, which helps you check something is what it claims to be.
• Spotting issues early. A stuck "pending" status or a "failed" result tells you what went wrong, so you know whether to wait or try again.

Two safety habits matter most. First, use the correct explorer for the network you used. Searching the wrong blockchain's explorer will simply show nothing, which can make a perfectly good transaction look like it failed.

Helpful tips

• Copy the full transaction ID. Missing a single character means the explorer will not find it, so copy and paste rather than typing it out.
• Use your wallet's built-in link. Most wallets and exchanges include a "view on explorer" button that opens the correct site for the right network automatically.
• Bookmark the explorers you use. A saved bookmark protects you from mistyping the address and landing on a fake copy.
• Wait for a few confirmations before treating a large transfer as final, especially for higher-value amounts.

Common mistakes to avoid

• Using the wrong network's explorer. This is the most common mistake. A transaction only shows on the explorer for the exact blockchain it was sent on. Not sure which to use? See choosing the right network for transfers.
• Panicking over a pending status. Give a busy network time before assuming anything is wrong.
• Entering private details into an explorer. A genuine explorer only reads public data and will never ask for your seed phrase or private keys.
• Trusting a link from a message or email. Reach explorers through your own bookmark or wallet, not through links strangers send you.

What is a block explorer?

A block explorer is a website that lets anyone search and read the records on a blockchain, such as transactions, wallet addresses, and blocks. It turns hard-to-read blockchain data into a clear, human-friendly view.

Is a block explorer free?

Yes. Block explorers are public and free to use. You do not need to create an account, log in, or pay to look up a transaction or an address.

How do I check if my transaction went through?

Copy your transaction ID, paste it into the explorer for the correct blockchain, and read the status. A status of "Success" or "Confirmed" with a few confirmations means the transfer has gone through.

Can anyone see my wallet?

Yes. A wallet address and its full transaction history are public, so anyone can view them on an explorer. Your name is not attached to the address, but if someone links the address to you, they can see its balance and activity.

What is a transaction hash?

A transaction hash — also called a transaction ID or TxID — is the unique code that identifies a single transaction. You paste it into a block explorer to find and check that exact transfer.

A block explorer is a free, public search engine for a blockchain. It shows transactions, wallet addresses and balances, confirmations, fees, and block details. To check a transfer, paste the transaction ID into the correct network's explorer and read the status and confirmations. Always use the right, trusted explorer and never enter private details into one.
