In the OneKey App, transaction-related fees are primarily divided into two parts:
Swap / Bridge service fees
Perps trading-related fees
Different features have different fee structures.
1. Swap / Bridge Service Fees
The OneKey App provides an interface for users through the "Trade" module, which supports Swap and Bridge via integrated third-party providers. OneKey charges a service fee for facilitating this technology and routing infrastructure.
How are fees charged?
A 0.85% service fee is charged for all Swaps (same-chain exchange) and Bridges (cross-chain exchange) initiated through all channels.
There are no hidden fees; pricing is always displayed before confirmation.
How is the service fee calculated?
The service fee is calculated based on the transaction amount and the fee rate:
Service Fee = Transaction Amount × Fee Rate
Example:
Initiating a $10,000 Swap or Bridge
→ $10,000 × 0.85% = $85
When is the service fee deducted?
The service fee is automatically applied when executing a Swap / Bridge and is reflected in the final transaction details.
Will the fee rates or supported tokens change?
Yes. OneKey may adjust fee rates, supported networks, or token lists at its own discretion to maintain fairness, compliance, and operational efficiency.
We recommend that you review this notice regularly for the latest information.
2. Perps Trading Fees
When you trade on OneKey Perps, you will incur Trading Fees and Builder Fees.
Trading Fees
Trading fees are charged by Hyperliquid and follow Hyperliquid's official fee model.
Trading fees are calculated based on a user's rolling 14-day trading volume and are settled at the end of each day in UTC. Sub-account volume is counted toward the main account, and the main account and all sub-accounts share the same fee tier. Vault volume is calculated separately from the main account.
Referral rewards apply to a user's first $1 billion in volume, and referral fee discounts apply to the first $25 million in volume.
Maker rebates are distributed to the trading wallet in real-time with every execution. Users can claim referral rewards on the Referrals page.

Staking Tiers
After staking HYPE, users may receive trading fee discounts based on their staking tier. In general, the more HYPE staked, the higher the fee discount.
Please note that staking discounts apply only to trading fees and do not apply to Builder Fees.
For detailed staking tiers, thresholds, and the latest discount rules, please refer to the official Hyperliquid fee documentation.
HIP-3 Asset Explanation
Trading fees for HIP-3 assets are determined by Hyperliquid's rules. When Growth Mode is enabled, trading fees are generally lower. Please note that the OneKey Builder fee remains unchanged. For more details, please refer to the Hyperliquid official documentation and the official fee schedule.
Builder Fees
Platform Type | Common Trading Fees |
Centralized Exchange (CEX) | 0.10% - 0.20% |
OneKey Perps | 0.05% |
Total Fee Calculation
The total fee for a single filled order can be estimated using the following formula:
Total Fee = Filled Amount × Trading Fee Rate + Filled Amount × Builder Fee Rate
Filled Amount = Execution Price × Executed Quantity
Trading Fee Rate: determined by the user's current fee tier and whether the order is Maker or Taker
Builder Fee Rate: currently 0.05% on OneKey Perps
Example:
If an order is filled for 10,000 USDC and the Taker fee rate is 0.045%, then:
Total Fee = 10,000 × 0.045% + 10,000 × 0.05% = 4.5 + 5 = 9.5 USDC
Please note:
If the user is eligible for a HYPE staking fee discount, the actual trading fee may be lower than in the example above.
Perpetual and spot trading have different fee rates, so the applicable fee schedule should be used accordingly.
Actual fees may also be affected by referral discounts and whether the trade is executed as Maker or Taker.
Funding fees, liquidation fees, and withdrawal network fees are not included in the single-order fee formula above.
Other Fees
Withdrawal Fees
Fees incurred during withdrawal are determined by on-chain network gas fees and Hyperliquid's withdrawal rules.
Funding Rate
Perpetual contracts have no expiration date. To keep the contract price close to the spot price, the system uses a funding rate mechanism.
When the funding rate is positive, long positions pay short positions.
When the funding rate is negative, short positions pay long positions.
The funding rate is dynamically calculated by Hyperliquid and settled periodically.
