How to Use a Block Explorer to Check a Transaction
A block explorer is a public search engine for a blockchain, and you check a transaction by pasting its hash into the search box and reading three fields: the status, the number of confirmations, and the receiving address.

Key takeaways
- A block explorer is a public search engine for a blockchain, and you check a transaction by pasting its hash into the search box.
- Ethereum.org describes block explorers as a portal to real-time data on blocks, transactions, validators, accounts, and other onchain activity.
- A transaction status of pending means it has been broadcast but not yet included in a block.
- A failed transaction still consumes gas, so the fee is charged even though the transfer did not happen.
- Etherscan states that it is not funded, operated, or managed by the Ethereum Foundation.

A block explorer is a public search engine for a blockchain, and you check a transaction by pasting its hash into the search box and reading three fields: the status, the number of confirmations, and the receiving address.
That is the whole skill. The rest of this guide explains what the other fields mean and what an explorer can and cannot tell you, because the most common mistake is reading an explorer as proof of something it never claimed.
What a block explorer is
Ethereum's documentation puts it plainly: "Block explorers are your portal to Ethereum's data. You can use them to see real-time data on blocks, transactions, validators, accounts, and other onchain activity" (source: ethereum.org block explorers documentation, September 2026).
Every public blockchain has at least one block explorer. Etherscan describes itself as "the leading block explorer for the Ethereum Blockchain," letting users "easily look up, confirm, and validate transactions that have taken place on the Ethereum Blockchain" (source: Etherscan, September 2026). Note what it also says about itself: it is "not funded, operated, or managed by the Ethereum Foundation." An explorer is an independent company reading a public ledger, not part of the network.
That independence matters in one direction. The explorer does not control the chain and cannot change your transaction. It also means a given explorer can be wrong, slow, or down, and the underlying blockchain is unaffected either way.
Finding your transaction hash
A hash is the identifier assigned when a transaction is submitted. It is a long string beginning with 0x on Ethereum-style networks and a plain string of letters and numbers on Bitcoin.
- Get the hash from whichever side sent the funds. An exchange withdrawal screen shows it in the transaction history, often labeled TxID or transaction ID. A wallet shows it in the activity list for the transfer.
- Or search the receiving address instead. If you only have the address, search that and find the transaction in the address's history.
- Paste it into the explorer for the correct network. This is the step people skip. An Ethereum hash searched on a Bitcoin explorer returns nothing, and so does an Ethereum hash searched on an Ethereum layer 2 explorer.
Reading the status field
The status is the first thing to look at, and it takes one of three values.
| Status | What it means | What to do |
|---|---|---|
| Pending | Broadcast to the network but not yet included in a block. On a busy network this can persist while the fee you offered is below what validators are currently taking. | Wait. It is not lost. |
| Success | Included and executed. Funds moved. | Nothing. |
| Failed | Included in a block, but the execution did not complete. | Look for an insufficient gas limit, a contract condition that was not met, or a missing token approval. |
Confirmations
A confirmation is a block added on top of the block containing your transaction. One confirmation means it is in the chain. More confirmations mean more work would have to be undone to reverse it, which is why exchanges wait for a set number before crediting a deposit.
The number required differs by asset and by venue. If a deposit has not appeared, check the explorer for the confirmation count and then check the exchange's own stated threshold for that asset. Most "my deposit is missing" cases are a transaction that has confirmed on chain and is waiting on the platform's crediting rules. The platforms we track are listed at Exchanges.
The rest of the fields
Ethereum's documentation lists what a transaction view shows, and each field answers a specific question.
| Field | What it shows |
|---|---|
| From | "The address of the account that submitted the transaction." |
| To | The recipient address. |
| Value | "The total ETH value being transferred." |
| Gas | The limit set, the amount used, and the price per unit. Gas used multiplied by price is what the transfer cost you, separate from any fee the sending platform charged. |
| Nonce | "The transaction number for the from address," which is how a network orders transactions from the same sender. |
| Block and timestamp | When the transaction landed. |
From, to, and value together tell you whether the funds went where you intended, and they are what to check against the address you copied. On Ethereum, an explorer will also show whether the receiving address is a wallet or a smart contract, which is worth checking before a large send.
Checking an address
Searching an address instead of a hash shows its balance and its full transaction history. Explorers show "the amount of ETH associated with that account" along with the transactions in and out.
Two honest limits apply. First, an explorer shows the address, not the person. Labels attached to well-known addresses come from the explorer's own research and are not authoritative. Second, anyone can send dust or an unsolicited token to any address, so the presence of a token in a wallet's history says nothing about whether the owner wanted it. Unsolicited tokens are a common setup for a scam, and our guide on spotting a crypto scam covers the pattern.
Token and gas views
For token contracts, explorers show "whether they're an ERC-20, ERC-721 or another token standard" along with supply and holder counts. The holder count and the distribution across the top addresses are useful context on any small token.
Most explorers also run a gas tracker showing "estimated units of gas needed for a safe but slow transaction" plus average and fast estimates.
Frequently Asked Questions
My transaction says pending. What should I do?
Wait first. A pending transaction with a fee below the current market rate sits in the queue until conditions change. Some wallets let you resubmit the same nonce with a higher fee to replace it. Do not send the funds a second time.
The explorer shows success but my exchange has not credited me.
That combination is normal. The chain has done its part and the platform is applying its own confirmation threshold and internal checks. Compare the confirmation count on the explorer with the exchange's stated requirement for that asset before contacting support.
Can a block explorer tell me who owns an address?
No. It shows addresses and balances. Names attached to some addresses are the explorer's own labeling, and unlabeled addresses are simply unidentified.
Does using an explorer expose my wallet?
No. Explorers read public data and never need your private key or seed phrase. Any site that asks you to connect a wallet or enter a recovery phrase to "resolve" a transaction is not an explorer.
Which explorer should I use for my chain?
Each network has its own. Look up the explorer named in the official documentation for that chain rather than a search result, since fake explorer domains exist. For jurisdiction context on the platforms you are withdrawing from, see United States and the other jurisdiction pages.
