Understanding Harmony (ONE) and Its Token Structure

Harmony (ONE) is a blockchain platform designed to enhance scalability and interoperability through sharding technology. The native cryptocurrency, ONE token, is used for staking, transaction fees, governance, and network security. Before selling your ONE tokens, it’s essential to understand that they exist on the Harmony blockchain and are compatible with wallets and exchanges that support the ERC-20 or native ONE standards, depending on how they were acquired. If your tokens were obtained through staking or mainnet transfers, they are likely on the native Harmony chain. If acquired via an Ethereum bridge, they may be in ERC-20 form. Identifying the correct token type ensures a smooth selling process.

Selecting a Compatible Cryptocurrency Exchange

To sell your ONE tokens, you need to use a cryptocurrency exchange that lists Harmony. Not all exchanges support ONE, so verifying availability is critical. Prominent platforms such as Binance, KuCoin, Crypto.com, and Gate.io currently offer trading pairs for ONE against stablecoins like USDT or major cryptocurrencies like BTC and ETH. Before proceeding, confirm that the exchange supports the version of ONE you hold—whether native ONE or ERC-20. You can check the deposit page of the exchange for supported networks. Using an incompatible network may result in permanent loss of funds, so exercise caution during transfer.

Transferring ONE Tokens to an Exchange

Once you’ve chosen an exchange, you must transfer your ONE tokens from your wallet to your exchange account. Begin by logging into your exchange and navigating to the deposit section. Search for "ONE" and select the correct network (e.g., Harmony or Ethereum ERC-20). The system will generate a deposit address. Open your wallet—such as MetaMask, Trust Wallet, or the Harmony Wallet—and initiate a send transaction. Ensure the following steps are followed precisely:

• Confirm the token type matches the deposit network.
• Copy the deposit address carefully, avoiding any typos.
• Set the correct network in your wallet (e.g., switch MetaMask to Harmony Mainnet).
• Enter the amount you wish to sell.
• Review gas fees and confirm the transaction.

Wait for the blockchain to confirm the transfer. This may take a few minutes. Once credited, your ONE tokens will appear in your exchange wallet, ready for trading.

Executing the Sale on the Exchange

With your ONE tokens in the exchange wallet, you can now place a sell order. Navigate to the trading interface and locate the ONE/USDT or ONE/BTC trading pair. Choose between a market order or a limit order based on your preference:

• Market Order: Sells your ONE instantly at the best available price. Ideal for quick liquidation.
• Limit Order: Allows you to set a specific price at which you want to sell. The order executes only when market price reaches your target.

For a market order:

• Click on the "Sell" tab.
• Enter the amount of ONE you want to sell.
• Verify the estimated amount of USDT or BTC you’ll receive.
• Click "Sell" to execute.

For a limit order:

• Select "Limit" instead of "Market."
• Input your desired price per ONE token.
• Enter the quantity.
• Confirm the order.

Your order will appear in the exchange’s order book and execute when matched. Monitor the transaction history to confirm completion.

Withdrawing Funds to Your Bank or Wallet

After successfully selling your ONE tokens, you’ll have funds in the form of a stablecoin or another cryptocurrency. To convert to fiat (e.g., USD, EUR), you must withdraw to a bank account or a payment service. Most exchanges allow fiat withdrawal via:

• Bank transfer (SEPA, SWIFT, ACH)
• Debit card payout
• Third-party payment processors (e.g., Paxos, Simplex)

Go to the withdrawal section, select the currency (e.g., USDT or USD), and choose your preferred method. If withdrawing to a bank:

• Enter your bank account details.
• Specify the amount.
• Confirm identity verification if required.
• Submit the request.

Processing times vary from minutes to several business days. Alternatively, you can transfer crypto to a personal wallet like Ledger or Trezor for long-term storage. Always double-check withdrawal addresses and network compatibility to prevent loss.

Safeguarding Your Assets During the Process

Security is paramount when selling cryptocurrency. Use only reputable exchanges with strong security records. Enable two-factor authentication (2FA) using an authenticator app (e.g., Google Authenticator), not SMS. Avoid public Wi-Fi when accessing exchange accounts. Never share your wallet’s private key or recovery phrase. When transferring tokens, use the exchange’s official website—beware of phishing sites mimicking legitimate platforms. Check URLs carefully. Consider using a hardware wallet to store funds before and after the sale to minimize exposure to online threats.

What happens if I send ERC-20 ONE tokens to a native ONE deposit address?

Sending ERC-20 tokens to a native ONE address will result in permanent loss. Always confirm the deposit network on the exchange matches your token standard before initiating a transfer.

Are there taxes when I sell my ONE tokens?

Tax obligations depend on your jurisdiction. In many countries, selling cryptocurrency is a taxable event. Consult a tax professional to report capital gains or losses accurately.

How long does it take for ONE transactions to confirm on the exchange?

Harmony network transactions typically confirm within 2–5 seconds, but exchange credit may take a few minutes due to internal processing. ERC-20 transfers may take longer depending on Ethereum network congestion.
