A step-by-step guide! Securely transfer BTC from OneKey to Bitkub

Transferring coins from OneKey (Hardware Wallet) back to Bitkub (Exchange) is typically done for the purpose of selling coins or exchanging them for other assets on the Exchange. This reverse transfer has different steps from transferring out of an Exchange; you will need to "Sign" the transaction through your OneKey device to confirm that only you are authorizing the transfer.

This guide will walk you through each step in detail to ensure your coin transfer is correct and secure.

Part 1: Preparing the Destination Address (from Bitkub)

First, you need to generate a Deposit Address on Bitkub to input into OneKey Suite.

1.1 Copy the BTC Deposit Address on Bitkub

• Log in to the Bitkub app.
• Go to the “Wallet” menu.
• Go to the "Deposit" menu.
• Select the coin you wish to receive, in this case, “BTC”.
• Verify the network: Ensure that the displayed network is "Bitcoin" only. Currently, Bitkub only supports the Bitcoin network.
• Copy the Address: Bitkub will display the BTC Deposit Address for depositing coins (starting with bc1…). Copy this address. Alternatively, save the image below to save the QR Code for receiving coins.

Part 2: Initiating the Transfer from OneKey App

Now, we will enter the OneKey App to command OneKey to transfer coins.

2.1 Go to the "Send" page on OneKey App

• Connect your OneKey device to your mobile phone, open the OneKey App, and select the Bitcoin account where you hold coins.
• Tap the "Send" tab on the screen.

2.2 Fill in the transfer details

• Recipient Address: Paste the BTC Address you copied from Binance TH.
• Caution: You should check if the first 5 and last 5 characters of the address you copied match the address from Binance TH to prevent errors.
• Amount: Enter the amount of BTC you wish to transfer back to Binance TH.
• Transaction Fee: Select your desired fee (higher fee means faster transfer). The OneKey App will suggest an appropriate fee. Initially, a "Normal" fee is recommended.
• Press "Preview": Press Preview to prepare the transaction.

2.3 Confirm details on OneKey

• (Very Important) You must ensure that the destination address displayed on the OneKey device screen matches the BTC deposit address in Binance TH 100%. If the address on your computer was altered by malware, you would be able to detect it at this step, because the address on the OneKey device will still be the correct one.

• Confirm the amount of coins to send.
• Confirm the total coin amount and fees.
• Confirm the transaction signing.

2.4 Review final transaction details on OneKey App and press send.

2.5 Check for success in the OneKey App.

When your transaction shows "Sent BTC" and "Confirmed," it means you have initially succeeded! Your digital assets have been successfully sent to the Exchange.

You just need to check the status on Binance TH one last time to confirm the transfer and its completion.

Part 3: Confirming Success on Bitkub

• Receive coins on Bitkub: Once the Bitcoin network confirms the transaction as required by Bitkub (usually takes 10-30 minutes) (depending on the transaction fee), the BTC will appear in your wallet on the Bitkub app.

You've done it! This proves that you can truly control your coins and transfer them securely to the Exchange.
