A blockchain transaction can feel opaque when funds do not appear immediately. You may have sent crypto to a wallet or deposited it to Phemex, received a transaction ID, and then watched the balance remain unchanged. In most cases, the transaction is not lost—it is waiting for a network confirmation, platform processing, or a required deposit detail such as the correct network or memo.
Blockchair is a multi-chain blockchain explorer and on-chain data tool that helps users inspect public transaction records, wallet activity, blocks, and fees. Instead of relying solely on a wallet’s “sent” status, you can use the transaction hash (TxID) to see what the blockchain itself reports.
This guide explains how to check transaction status with Blockchair, identify the cause of a delayed transfer, estimate whether gas fees are adequate, and use public wallet data responsibly.
What Is Blockchair?
Blockchair is a blockchain search engine and explorer. It lets users search public on-chain data using a transaction ID, wallet address, block number, or keyword. Its core value is simple: it turns a blockchain’s raw public ledger into a readable transaction record.
Depending on the network, a Blockchair transaction page may show:
- Transaction status and confirmation state
- Sender and recipient addresses
- Asset amount and token transfers
- Block number and timestamp
- Network fee or gas fee paid
- Input and output details
- Smart-contract interactions
- Related address activity
Blockchair supports numerous public blockchain networks. The exact network list and available data fields can change over time, so check the platform’s live blockchain selector before searching. Bitcoin, Ethereum-compatible networks, and several other major chains may present transaction information differently because their data models are not identical.
For example, a Bitcoin transaction typically displays inputs, outputs, fees, and confirmation count. An Ethereum-style transaction may also display gas used, gas price, nonce, method calls, token transfers, and whether a smart-contract execution succeeded.
The Fast Answer: How to Check a Transaction by TxID
To check whether a crypto transaction is stuck, copy the TxID from your sending wallet or Phemex transaction history, open Blockchair, select the correct blockchain, and paste the TxID into the search field. Review whether the transaction is pending, confirmed, failed, or not found.
A TxID is also called a transaction hash or TxHash. It is a unique identifier for a blockchain transfer. It is not the same as a wallet address, order number, or account UID.
If a transaction is confirmed on-chain but your Phemex deposit has not arrived, the blockchain portion of the transfer is complete. The next step is to review the deposit’s network, amount, memo/tag requirements, and Phemex deposit status.
Step-by-Step: How to Check Transaction Status With TxID
1. Find your transaction hash
Where you find the TxID depends on where the transfer began:
- In a self-custody wallet, open transaction history and select the transfer.
- On Phemex, open Assets and view your deposit or withdrawal history.
- In another sending service, open the completed transaction details.
For Phemex withdrawals, the TxID becomes available in the withdrawal record after the transfer is submitted to the blockchain. If no TXID has been generated yet, the transfer has not reached the on-chain stage. Phemex’s withdrawal FAQ explains how to locate the transaction hash and what to do when a withdrawal remains pending.
2. Select the correct network
This is the step users most often overlook. The same asset can exist on multiple networks. A transaction hash must be searched on the blockchain where it was sent.
If you withdrew a token using one network, searching that transaction on a different network’s explorer will not produce a useful result. First confirm the selected coin and chain in your withdrawal record, then choose the corresponding chain on Blockchair.
3. Paste the TxID into Blockchair
Copy the full transaction hash and paste it into the search bar. Avoid manually retyping it; one missing character produces an invalid search.
A valid transaction page should show the status, time, sender, recipient, amount, and fees. Save the URL if you need to share the on-chain record with support. Never share your wallet seed phrase, private key, or account password—none of these are needed to verify a TxID.
4. Read the transaction status
The key fields to check are:
Pending or unconfirmed: The transaction has been broadcast but is still waiting to be included in a block. This often occurs during network congestion or when the attached fee is too low.
Confirmed: The transaction is included in a block and has received confirmations. This means the blockchain transfer completed, though the receiving platform may still need time to credit the deposit.
Failed: The transaction was included on-chain but did not execute as intended. On smart-contract networks, this can happen when a contract call reverts, the gas limit is insufficient, or a token transfer fails under contract rules.
Not found: Recheck the TxID and network. If it is still not found, the transfer may not have been broadcast, or you may be looking at an internal platform status rather than an on-chain transaction.
Why Is My Crypto Transfer Stuck?
A “stuck” transfer can refer to several different situations. Identifying which stage is delayed prevents unnecessary panic.
The transaction has no confirmation
If Blockchair shows an unconfirmed transaction, the network has not finalized it. Congestion and low fees are common reasons. Your sender wallet may offer options such as fee bumping, replacement, or acceleration, but availability depends on the blockchain and wallet. Do not send a second transfer to “fix” the first one unless you understand how that chain handles replacement transactions.
The transaction is confirmed, but the deposit is missing
A confirmed TxID proves that the blockchain processed the transfer. It does not automatically prove that the receiving account can credit it.
Check these items:
- The deposited coin and network match the selected Phemex deposit route.
- The transfer meets the minimum deposit amount.
- A required memo, tag, or destination identifier was included.
- The token contract matches the supported asset.
- The deposit is not affected by wallet maintenance, a network upgrade, or a security review.
Phemex notes that on-chain confirmation times vary with blockchain traffic, and users must select the same network at both the sending and receiving ends. Review the official Phemex deposit instructions before initiating a transfer.
The withdrawal is still pending before broadcast
If Phemex shows a status such as pending confirmation, security checking, pending review, or pending transfer, there may be no on-chain TxID yet. This is a platform-side processing stage, not a blockchain failure.
Phemex’s official guidance distinguishes these states and provides the appropriate support path for extended reviews. Do not assume a withdrawal is on-chain until a TxID is visible in the withdrawal details. Review the official withdrawal guide for the current workflow, network-selection requirements, and withdrawal history steps.
How to Check Gas Fees on Blockchair
Network fees compensate validators or miners for processing transactions. On Ethereum-compatible networks, this is often called gas. A transaction can remain pending when its offered fee is too low compared with current network demand.
On a transaction page, look for fields such as:
- Total transaction fee
- Gas price
- Gas used
- Gas limit
- Fee rate
- Transaction size
The most important comparison is not whether you paid “a fee,” but whether the fee was competitive when the transaction was broadcast. During sudden spikes in network activity, a fee that was reasonable minutes earlier may no longer be attractive to block producers.
For token transfers and smart-contract interactions, distinguish between gas limit and gas price. The gas limit is the maximum computation the transaction may consume. The gas price determines what you are willing to pay per unit of computation. A failed contract call may still consume some gas because the network processed the attempted execution.
Before sending funds, check current network conditions in your wallet or a trusted network-fee monitor. For important deposits, verify the destination address, network, token contract, and memo/tag before approving the transaction. A few seconds of review is far cheaper than an asset-recovery request.
How to Research Whale Wallets Responsibly
Blockchair can also help users inspect large public wallet balances and transaction flows. Search an address to see its visible holdings, transaction history, and transfers to or from other public addresses.
This is useful for research, but it requires context. A large address is not automatically a “whale,” and a large transfer is not automatically a bullish or bearish signal. The address may belong to a smart contract, treasury, custodian, bridge, service wallet, or internal operational system.
Use on-chain wallet research as one input, not as a trading instruction:
- Check whether the address is a contract or externally owned account.
- Look at repeated behavior over time, not one transaction.
- Separate token transfers from native-asset transfers.
- Avoid assuming the owner’s identity without verifiable evidence.
- Never send funds to an address simply because it has a large balance.
Public blockchain data is transparent, but it is rarely self-explanatory.
How to Avoid Stuck Transfers When Depositing to Phemex
Use this pre-transfer checklist every time:
- Select the identical coin and network on both sides.
- Confirm the deposit address directly from your Phemex account.
- Include a memo or tag when the deposit page requires one.
- Confirm the minimum deposit amount and applicable fees.
- Verify the token contract when depositing a token.
- Send a small test amount first when using a new route.
- Save the TxID after sending.
- Wait for on-chain confirmations before escalating.
If a deposit is confirmed on-chain but not credited, Phemex asks users to provide the coin/token, network, amount, and transaction hash when contacting support. Its deposit-not-credited guide also covers confirmation delays, insufficient fees, wallet maintenance, and security-check statuses.
FAQ
Can Blockchair cancel or reverse a transaction?
No. Blockchair is an explorer for public blockchain data. Once a transaction is confirmed, it generally cannot be reversed by an explorer, wallet provider, or exchange.
Why does my transaction show confirmed but my Phemex balance has not updated?
The blockchain transfer may be complete while the deposit is still being matched, checked, or credited. Verify the network, amount, memo/tag, and supported token details first.
What should I send to support for a delayed crypto deposit?
Provide your Phemex UID or registered email, the coin, network, amount, and TxID. A transaction hash or explorer link is more useful than a screenshot.
A TxID is your most useful proof of an on-chain transfer. With Blockchair, you can identify whether a delay is caused by the network, a fee issue, or a receiving-side requirement—and use the official Phemex deposit and withdrawal guidance to take the right next step.
