On-chain queries are a fundamental skill for anyone involved in the cryptocurrency space. They allow you to verify transactions, check wallet balances, and review smart contract interactions directly on the blockchain. For users of OKX Exchange, understanding how to perform these queries can enhance transparency, security, and overall confidence in your digital asset activities.
This guide provides a clear, step-by-step approach to conducting on-chain queries related to transactions made through OKX. You will learn how to locate necessary information like Transaction Hashes (TxID), select the appropriate blockchain explorer, and interpret the results.
What Is an On-Chain Query?
An on-chain query involves using a blockchain explorer to access data recorded on a distributed ledger. Every transaction, wallet address, and block is publicly stored and can be reviewed by anyone. These queries help you track transaction statuses, verify amounts, monitor gas fees, and confirm receipt of funds.
How to Perform an On-Chain Query from OKX
It’s important to note that OKX itself does not host an internal blockchain explorer. Instead, users rely on external blockchain explorers compatible with the network on which the transaction occurred. OKX supports multiple blockchains, including Bitcoin, Ethereum, BSC, and Tron, so you’ll need to use the corresponding explorer for each.
Step 1: Obtain the Transaction Hash (TxID)
The Transaction Hash, or TxID, is a unique string of characters that identifies a specific transaction on the blockchain. After completing a withdrawal or transfer on OKX, you can find this ID in your account history.
Here’s how to locate your TxID on OKX:
- Log in to your OKX account via the app or website.
- Navigate to the "Assets" or "Funds" section.
- Select "Transaction History" or "Records".
- Find the relevant transaction and click "Details".
- Copy the TxID, which usually begins with characters like
0x(for Ethereum-based chains) or a long string of letters and numbers.
Step 2: Choose the Right Blockchain Explorer
Each blockchain has its own dedicated explorer. Using the correct one is essential for accurate results.
Common blockchain explorers include:
- Ethereum (ETH): Etherscan
- Bitcoin (BTC): Blockchair or Blockchain.com
- Binance Smart Chain (BSC): BscScan
- Tron (TRX): Tronscan
Make sure you match the explorer to the network your transaction used.
Step 3: Enter the Transaction Hash
Once you’ve selected the appropriate blockchain explorer:
- Go to the website’s search bar.
- Paste the TxID you copied from OKX.
- Press "Enter" or click the search button.
The explorer will display detailed transaction information, such as:
- Transaction status (e.g., confirmed, pending, or failed)
- Amount transferred
- Timestamp of the transaction
- Sender and receiver addresses
- Network fees (gas costs)
This data allows you to verify that a transaction was completed successfully.
Step 4: Check Wallet Balances and History
You can also use a blockchain explorer to review the balance and full history of any wallet address. Simply enter the public wallet address into the search bar of the relevant explorer. This will show all incoming and outgoing transactions, current holdings, and other on-chain activity associated with that address.

Important Considerations
- Network Compatibility: Always double-check that you are using the blockchain explorer for the correct network. Data from one chain (e.g., Ethereum) will not appear on another (e.g., BSC).
- Transaction Confirmation Times: Some transactions may stay in a "pending" state for several minutes or even hours, depending on network congestion. Allow time for confirmations.
- Privacy Awareness: Remember that blockchain data is public. Avoid sharing sensitive information or using wallets linked to your identity for maximum privacy.
Mastering on-chain queries helps you become a more informed and independent cryptocurrency user. With the steps outlined above, OKX users can easily monitor transactions, improve security, and engage more deeply with blockchain technology.
Frequently Asked Questions
What is a transaction hash (TxID)?
A transaction hash is a unique identifier assigned to every blockchain transaction. It is used to track and verify transactions on public explorers.
Can I query transactions without a TxID?
If you don’t have the transaction hash, you can still look up activity using a wallet address. However, the TxID provides the most direct and precise way to locate a specific transaction.
How long does it take for a transaction to appear on the blockchain?
Most transactions are recorded within minutes, but during times of high network activity, delays can occur. The status will update from "pending" to "confirmed" once processed.
What should I do if my transaction is stuck or fails?
First, check the transaction status via the blockchain explorer. If it remains stuck for an extended period, you may need to contact OKX support for assistance resolving the issue.
Are on-chain queries free to perform?
Yes, using blockchain explorers is free. These platforms provide read-only access to public blockchain data.
Can I perform an on-chain query for any cryptocurrency?
Most major cryptocurrencies with public blockchains can be queried via an explorer. However, some private or permissioned chains may not offer public access to transaction data.
