A small test transfer is a standard procedure when withdrawing from OKX to a cold wallet. The amount is not fixed; 0.001 BTC or an equivalent token amount is commonly suggested. After a successful test, you must wait for the cold wallet to confirm receipt before making a large transfer. If the test fails, check the address and network matching, and try again with a correctly copied cold wallet address.

Why a small test transfer is required
When withdrawing assets from OKX to a cold wallet, the biggest risk is an incorrect address or network mismatch. A cold wallet address is usually a long string of characters; manual entry or copy-paste can easily go wrong. Once assets are sent to the wrong address, they are almost impossible to recover.
Therefore, OKX's withdrawal security process clearly requires that before making a large transfer, you first perform a "trial run" with a very small amount to verify the address, familiarize yourself with the process, and confirm that the cold wallet can receive and display the asset correctly.
Prerequisite: You already have an offline cold wallet address (e.g., one generated by Ledger or Trezor) and have completed identity verification on OKX.
Test amount, time limit, and processing
Choosing the test amount
OKX official guidance suggests a reference test amount of 0.001 BTC or 0.01 ETH equivalent. There is no mandatory standard; the key principle is that it should be much smaller than your planned large transfer while covering the network miner fee.
Specific suggestions:
Major coins (BTC/ETH): Use the minimum withdrawal amount or a slightly higher small amount, such as 0.001 BTC or 0.01 ETH.
Other tokens (USDT, etc.): Use the minimum withdrawal amount as a test; you can check the "Minimum withdrawal amount" hint on the withdrawal page.
Test time limit
An OKX withdrawal goes through several statuses: "Waiting for withdrawal" → "Manual review" (if triggered) → "Withdrawing" → "Withdrawal successful".
Normal situation: After an on-chain withdrawal is broadcast, you usually need to wait for blockchain confirmations. For instance, BTC requires 6 or more confirmations to be considered secure.
Hot-to-cold wallet transfer: Under regulatory requirements, some user assets are stored in cold wallets. If the hot wallet balance is insufficient, the withdrawal may be delayed by up to 24 hours, during which it will show as "Processing" but hasn't been broadcast on-chain. If you don't want to wait, you can cancel the withdrawal request yourself, but re-submitting after cancellation will not speed up arrival.
How to confirm success after the test
Check the transaction status under "Assets" → "Withdrawal history" on OKX, and copy the transaction hash (TxID) to the corresponding blockchain explorer to track confirmation status.
The most crucial step: Open your cold wallet software and confirm that the test amount has successfully appeared in the balance. Only when the cold wallet shows receipt of this small amount can you be certain the address and network are correct.

Failure handling
Case A: Withdrawal status shows "Manual review"
The system has triggered risk control; a customer service agent will call to verify your identity. Keep your phone accessible, complete the verification, and the withdrawal will proceed.
Case B: Test amount hasn't arrived for a long time
Check the withdrawal record status: If it shows "Withdrawing" but there is no TxID after more than an hour, it may be a hot-to-cold wallet transfer delay. The official explanation states that delays can be up to 24 hours; waiting patiently is recommended.
If you need urgent action, you can cancel the current request and re-withdraw, but cancellation clears the current progress and re-withdrawing will not speed things up, so this is not recommended.
Case C: Cold wallet does not receive the test amount
First check: Confirm that the withdrawal network selected on OKX matches exactly the network supported by the cold wallet address, such as BTC network, ERC-20, etc.
Second: Use the TxID on a block explorer to verify whether the transaction has been packaged and confirmed. If there are enough confirmations but the cold wallet still does not show it, the wallet software may be out of sync; try refreshing or reconnecting the device.
If none of the above works: Copy the cold wallet address again and initiate a new test from scratch. Never make a large transfer without confirming the address is correct.
Risk reminder: When selecting the withdrawal network, it must be identical to the deposit network of the cold wallet address; otherwise, assets will be permanently lost and cannot be recovered. Also, always use the official OKX website and beware of phishing sites and scammers impersonating customer support.
After completing the above, how to confirm you can proceed with a large transfer?
The sole confirmation criterion: The cold wallet has successfully received and displayed the test amount. Once confirmed, submit a large withdrawal request using the same cold wallet address on the OKX withdrawal page. If the large withdrawal is restricted due to a "new address withdrawal lock" (e.g., cannot withdraw to a new address within 24 hours), you may need to wait for the protection period to end, or whitelist the cold wallet address in the address book in advance.
