1. USDC-Based Settlement (Arbitrum Network)
OneKey Perps uses USDC-based settlement.
Your profits, losses, margin, and fees are all displayed and settled in USDC, making it easy to track your account performance intuitively.
2. Deposits
Workflow: Click "Deposit" in the top left corner and select the assets from your wallet.
Preferred Asset: Depositing USDC on the Arbitrum network ensures an instant credit upon confirmation.
Automatic Bridging and Swapping: If you deposit other assets (e.g., Ethereum USDT, Arbitrum USDT), the system will automatically utilize third-party protocols to convert them into USDC on the Arbitrum network.
Deposit Minimum: Each deposit must be ≥ 5 USDC.
3. Deposit Deduction Explanation
During the deposit process, you may notice that the amount received is slightly lower than the sent amount; this typically includes the following three transparent costs:
Bridge Fees: Network transmission and liquidity fees charged by third-party protocols.
Exchange Loss (Slippage): Standard price differences caused by on-chain price fluctuations when converting USDT or other tokens to USDC.
Platform Service Fee: A 0.85% fee charged for the cross-chain exchange service.
4. Withdrawals
Workflow: Click "Deposit" in the top left corner, then switch to the "Withdraw" tab in the pop-up window.
Confirm Amount: Enter the amount you wish to withdraw and click confirm.
Receipt of Funds: Once the withdrawal transaction is confirmed on-chain, the funds will be automatically credited to your USDC balance on the Arbitrum network in your wallet.
Withdrawal Costs:
When withdrawing from your Perp account to your wallet, withdrawal fees are subject to the underlying protocol’s (Hyperliquid) applicable rules and the fees displayed at the time of withdrawal.
Before withdrawing, review the actual fees and the estimated amount you will receive, and ensure that your withdrawal amount is sufficient to cover the applicable fees.
