I. USDC-Dominated Settlement (Arbitrum Network)
OneKey Perps adopts USDC-dominated settlement.
Your profits, losses, margin, and fees are all displayed and settled in USDC, making it easy to intuitively grasp account PnL.
II. Deposits
Operation Path: Click "Deposit" in the upper left corner and select the asset in your wallet.
Preferred Asset: Deposit USDC on the Arbitrum network; it will be credited immediately upon confirmation.
Automatic Cross-Chain and Conversion: If you deposit other assets (e.g., USDT on Ethereum, USDT on Arbitrum), the system will automatically invoke a third-party protocol to convert them into USDC on the Arbitrum network.
Deposit Threshold: The minimum deposit amount per transaction must be ≥ 5 USDC.
III. Deposit Loss Explanation
During the deposit process, you may notice that the credited amount is slightly less than the sent amount. This usually includes the following three transparent costs:
Cross-Chain Bridge Fee: Network transfer and liquidity fees charged by the third-party protocol.
Conversion Loss (Slippage): The normal price difference resulting from on-chain price fluctuations when converting USDT or other tokens to USDC.
Platform Channel Fee: A 0.25% rate charged for cross-chain conversion services.
IV. Withdrawals
Operation Path: Click "Deposit" in the upper left corner, and switch to the "Withdraw" tab in the pop-up window.
Amount Confirmation: Enter the amount you wish to withdraw and click confirm.
Asset Arrival: After the withdrawal transaction is confirmed on-chain, the funds will be automatically credited to your USDC balance in the Arbitrum network wallet.
Withdrawal Costs:
For every withdrawal operation from the Perp account back to the wallet, the underlying protocol (Hyperliquid) will automatically deduct 1 USDC as a network service fee.
Please pay attention to your balance during withdrawal to ensure the withdrawal amount is sufficient to cover this fixed cost.
