DeFi Kingdoms is a popular pixel-style GameFi project on the Harmony blockchain. To start playing, you’ll need the native token, ONE, in your MetaMask wallet. This guide walks you through the process of purchasing ONE on OKX and withdrawing it safely to your wallet.
Understanding DeFi Kingdoms and the ONE Token
DeFi Kingdoms is a play-to-earn game that combines decentralized finance with a fantasy-themed universe. It operates on the Harmony blockchain, and its in-game currency is JEWEL. However, to perform transactions and pay for gas fees, you need ONE tokens.
The Harmony network is known for its fast transaction speeds and low costs, making it ideal for gaming and DeFi applications. ONE is the native utility token that powers this ecosystem.
Step-by-Step Guide to Withdrawing ONE from OKX
Step 1: Log In to Your OKX Account
Begin by logging into your OKX account. If you don’t have one, you’ll need to create an account and complete the KYC verification process. Once logged in, navigate to the 'Assets' section located at the top right of the dashboard.
Step 2: Initiate the Withdrawal Process
Within the 'Assets' section, click on 'Withdraw'. You will be presented with a list of cryptocurrencies available for withdrawal.
Step 3: Select ONE as Your Withdrawal Currency
In the search bar, type “ONE” to filter the list. Select Harmony (ONE) from the options. Ensure the network is set to 'ONE-Harmony'. This is a crucial step, as selecting the wrong network could result in a loss of funds.
Step 4: Enter Your Wallet Address
You will need to enter your external Harmony wallet address. This is your MetaMask address formatted for the Harmony network. Importantly, the OKX platform requires addresses to be in a 'one1...' format, not the standard '0x...' Ethereum-style format used by MetaMask.
To convert your address, visit the Harmony Explorer. Paste your '0x...' address into the search bar, and the explorer will display the corresponding 'one1...' address. Copy this converted address.
Back on OKX, you can add this address to your address book for future use. Click 'Add Withdrawal Address', paste your 'one1...' address, and add a memo for easy identification later.
Step 5: Confirm and Execute the Withdrawal
Paste or select your saved Harmony address. Enter the amount of ONE you wish to withdraw. It is highly recommended to send a small test amount first to verify the process before transferring a larger sum. Confirm the transaction by entering your fund password and the 2FA codes sent to your email and mobile device.
Step 6: Transaction Confirmation
After confirming, you will see a 'Withdrawal Successful' message. The transaction will usually be processed within a few minutes. You can track its status in the 'Withdrawal History' tab. Once completed, your ONE tokens will appear in your MetaMask wallet.

Frequently Asked Questions
Why does my MetaMask address need to be converted for ONE?
The Harmony blockchain uses a different address encoding (one1...) than the Ethereum hex format (0x...) that MetaMask displays by default. The Harmony Explorer tool seamlessly converts between the two formats to ensure compatibility.
What is the minimum withdrawal amount for ONE on OKX?
The minimum withdrawal amount can change based on network conditions. Always check the current limit on the OKX withdrawal page before initiating a transaction to avoid errors.
How long does a ONE withdrawal from OKX usually take?
Withdrawals on the Harmony network are typically very fast, often completing within 2-5 minutes. If your transaction is pending for longer, you can use the transaction ID from OKX to check its status on the Harmony Explorer.
Are there gas fees for receiving ONE in my wallet?
While OKX charges a withdrawal fee, receiving tokens on the Harmony network does not require you to pay a gas fee. The sender (OKX in this case) covers the transaction cost.
Can I use this same process for other cryptocurrencies?
Yes, the general withdrawal process is similar for most tokens. The critical steps are always selecting the correct blockchain network and ensuring the destination address is in the proper format for that specific network (e.g., cosmos1... for ATOM).
Is it safe to store my ONE in MetaMask?
MetaMask is a reputable and secure software wallet. For optimal security, especially for larger holdings, consider connecting your MetaMask to a hardware wallet like Ledger or Trezor, which keeps your private keys offline.
