Hands-on Guide! Securely Transferring BTC from OneKey to Binance TH

Transferring coins from OneKey (Hardware Wallet) back to Binance TH (Exchange) is usually done for the purpose of selling coins or exchanging them for other assets on the Exchange. This return transfer process differs from transferring out of an Exchange in that you will need to "Sign" the transaction via 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 accurate and secure.

Part 1: Preparing the Destination Address (from Binance TH)

First, you need to create a Deposit Address on Binance TH to input into the OneKey App.

1.1 Copy the BTC Deposit Address on Binance TH

• Access the Binance TH app.
• Go to the “Assets” menu.
• Go to the "Deposit" or "Add Funds" menu.
• Select the deposit method. Here, choose “Deposit Crypto”.
• Select the coin you wish to receive. Here, choose “BTC”.
• Verify the network, making sure the displayed network is "Bitcoin" only.
• A notification will appear regarding deposit support, which supports deposits from all BTC Addresses starting with “1”, “3”, “bc1p”, “bc1q” for all standards. Click “Continue”.
• Copy Address: Binance TH will display the BTC Deposit Address (starting with bc1…) for depositing coins. Copy this Address and keep it ready. Or 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, open the OneKey App, and select the Bitcoin account where you have coins.
• Tap the "Send" tab on the screen.

2.2 Enter Transfer Details

• Recipient Address: Paste the BTC Address you copied from Binance TH.
• Caution: You should check the first 5 characters and the last 5 characters of the Address you copied to see if they 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, we recommend "Normal".
• Click "Preview": Click Preview to prepare the transaction.

2.3 Confirm the accuracy of the details on OneKey

• (Very Important) You must check the destination Address on the OneKey device screen to ensure it matches the BTC deposit Address in Binance TH 100%. This is because if the Address is changed by malware on your computer, you will be able to detect it at this step, as the Address on the OneKey device will still be the correct Address.

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

2.4 Review the final transaction details on the OneKey App and click send.

2.5 Check for success in the OneKey App.

When your transaction shows “Sent BTC” and “Confirmed”, it means you have successfully completed the initial steps! Your digital assets have been 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: Checking for Success on Binance TH

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

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