How to Use a Bitcoin Explorer: Verify Your TXID, Sends, and Deposits Yourself
The Short Answer
Using a Bitcoin explorer is simple: just paste the "TXID" (transaction ID) that was issued when you sent your coins into the search box. The explorer then shows you exactly where that transaction stands right now (unconfirmed = waiting in the mempool, or confirmed), how many confirmations it has, the fee that was paid, and the sending and receiving addresses along with the amount. If you're worried about whether funds have arrived, you can treat 1 or more confirmations as "included in a block = effectively received." Explorers are free for anyone to use, and their greatest value is that you can verify the truth yourself without having to contact an exchange or the person you sent to.
Key points of this article
- Just paste the TXID into the search box and anyone can see, for free, where a transfer stands (unconfirmed / confirmed)
- Confirmations measure "how many blocks have been stacked on top" = how hard the transaction is to reverse. Six confirmations are generally treated as final
- Pending (unconfirmed) = waiting in line in the mempool. A low fee makes it more likely to stall. Don't panic and re-send
- Search an address and you can see its balance and full history of deposits and withdrawals. The blockchain is a public ledger, so nothing here is secret
What a Blockchain Explorer Actually Is
An explorer is a free browsing tool that makes Bitcoin's public transaction ledger (the blockchain) searchable by anyone. Because every Bitcoin transaction is published and stored on nodes around the world, any third party can read the details as long as they have a TXID or an address.
In other words, an explorer isn't a "bank teller window" — it's more like the search terminal in a public library. What it shows isn't the opinion of an exchange or wallet provider; it's the facts on the chain themselves. That's why you can neutrally verify with your own eyes whether "the exchange says it sent the coins, but did they really arrive?"
Some of the most widely used explorers are listed below.
| Explorer | Characteristics | Good for |
|---|---|---|
| mempool.space | Visualizes the mempool (the queue of unconfirmed transactions) and fees in real time. Open source | Those who want a detailed view of confirmation status and current fee rates |
| Blockchain.com Explorer | Long-established with a simple interface. TXID/address search is easy to follow | Beginners who just want to confirm that funds arrived |
| Blockstream.info | Few ads and privacy-oriented | Those who want to check without extra clutter |
Whichever you use, the "facts" shown for a given TXID or address are the same. Getting comfortable with just one is enough to start.
How to Track Your Own Transfer by TXID
The basic steps for tracking Bitcoin you've sent are as follows.
- Get the TXID — In the transaction history of the sender (an exchange or wallet), copy the 64-character alphanumeric string shown under a label like "Transaction ID" or "TxHash."
- Paste it into the explorer's search box — Paste it into the search box on mempool.space or a similar site and search.
- Read the status — "Unconfirmed" means it's waiting in line in the mempool; "◯ confirmations" means it has been confirmed.
- Cross-check the destination and amount — Confirm that the receiving address and amount shown under Outputs match the recipient and amount you intended.
If you don't have the TXID on hand, you can search by the receiving address instead. This lists the deposit/withdrawal history and balance tied to that address.

The Fields You Must Always Check on an Explorer
A TXID page lists a lot of information, but for confirming that funds arrived you can narrow it down to these five.
| Field | Example English label | What it tells you |
|---|---|---|
| Confirmations | Confirmations | How many blocks have been stacked on top of the block that included your transaction (how hard it is to reverse) |
| Status | Unconfirmed / Confirmed | Whether it's waiting in the mempool or already settled in a block |
| Sender | Inputs / From | Which address the coins were sent from |
| Destination / amount | Outputs / To | Which address receives how much (does it match your intended recipient?) |
| Fee | Fee (sat/vB) | The miner fee paid. A low fee can cause slow confirmation |
The most important of these is confirmations. A confirmation refers to "how many times a new block has been stacked on top of the block containing your transaction." The more confirmations there are, the more practically impossible it becomes to reverse (undo) the transaction, and six confirmations are generally treated as fully final. For a deeper look at what confirmations mean, see what is a confirmation.
How to Correctly Read "Pending (Unconfirmed)"
Even if you see "Unconfirmed" or "Pending" right after sending, that is not a failure. A Bitcoin transaction first enters the mempool (memory pool) = the queue of unconfirmed transactions on every node, and waits at zero confirmations until a miner includes it in a block.
The main reason confirmation is delayed is a low fee (sat/vB). When the mempool is congested, transactions with higher fees are processed first, so low-fee transactions get pushed back and may wait tens of minutes to several hours — even longer during heavy congestion. On mempool.space you can see the current fee market and where your own transaction sits, giving you a rough idea of "when it's likely to be picked up."
注意
Even if you get anxious while it stays unconfirmed, do not re-send the same funds twice. If the first transaction confirms later, you risk sending the coins twice. The basic approach is to first confirm with the TXID that the transaction exists in the mempool, and then wait. Also, this article is educational commentary, not investment advice. Crypto assets are highly volatile, and transfers cannot be reversed. Always double-check the address and amount yourself before sending.
How to Read an Address's Balance and History
If you enter a Bitcoin address into an explorer's search box, it displays that address's current balance and entire history of deposits and withdrawals. There are two things you should understand here.
- The blockchain is a public ledger — An address's balance and history can be viewed by anyone. An address is an anonymous number, but once it's linked to an identity, past transactions can be traced too.
- A balance is the sum of multiple UTXOs — A Bitcoin balance isn't a single number like a bank account; it's a collection of unspent "chunks (UTXOs)" you've received in the past. This mechanism is explained in detail in what is a UTXO. It's also why the fee appears as the difference between the input and output amounts.
Frequently Asked Questions
Q. I can't find my TXID. Where do I look? A. Open the "transaction history" or "withdrawal history" of your sending exchange or wallet, and you'll find a 64-character alphanumeric string under a label like "Transaction ID," "TxID," or "TxHash." Copy it and search for it on an explorer. If you're on the receiving side, you can also search by the receiving address.
Q. How many confirmations do I need before I can relax? A. It depends on the use case. For small amounts, 1 confirmation (inclusion in a block) can be treated as received in practice, but for large transactions or crediting deposits at an exchange it's common to use 6 confirmations as the standard. The required number varies by exchange, so check each exchange's help pages too.
Q. It's been unconfirmed for hours. What should I do? A. It's most likely stalled in the mempool because of a low fee. If your wallet supports it, you can raise the priority by re-broadcasting with a higher fee via "RBF (Replace-By-Fee)," or by adding a fee on the receiving side via "CPFP." If neither is supported, the basic approach is to wait for congestion to ease.
Q. Which explorer is correct? Can they show different things? A. Because every explorer reads the same blockchain, the facts for a given TXID (confirmations, amount, addresses) are essentially identical. Only the visual presentation and the method of estimating fees differ. If you're worried, look up the same TXID on two explorers and cross-check them to be sure.

FAQ
- Where can I find my TXID?
- Open the "transaction history" or "withdrawal history" of your sending exchange or wallet, where a 64-character alphanumeric string appears under a name like Transaction ID, TxID, or TxHash. Copy it and paste it into an explorer's search box to check the status of your transfer. If you're on the receiving side, you can also search by the receiving address.
- How many confirmations do I need before I can relax?
- For small amounts, 1 confirmation (inclusion in a block) can be treated as received in practice, but for large transactions or crediting deposits at an exchange it's common to use 6 confirmations as the standard. The required number varies by exchange, so check each exchange's help pages too.
- It's been hours and it's still unconfirmed (pending). What should I do?
- The fee is likely low and it's stalled in the mempool. If your wallet supports it, you can raise the priority via RBF (Replace-By-Fee) to bump the fee, or via CPFP on the receiving side. Avoid the danger of re-sending the same funds twice—first confirm the transaction exists using the TXID.
- Will the display be the same no matter which explorer I use?
- Yes. Because every explorer reads the same blockchain, facts such as confirmations, amount, and addresses are basically identical. Only the appearance and the method of estimating fees differ, so if you're worried, look up the same TXID on two explorers and cross-check them to be sure.
