# OKX xBTC Borrow Fee Rebate | Section | Key Points | | --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Eligibility |

• Wallet supplies xBTC only as collateral

• Borrows USDC or APT exclusively

• Adding any other asset as collateral voids eligibility

(work-around: open a separate profile for mixed collateral)

| | Fee flow |

• Borrow fees accrue and are charged in real time

• We track them for 30-day cycles starting 16 Jun → 16 Jul, 16 Jul → 16 Aug, etc.

| | Reimbursement cadence | • 100 % of fees paid in the previous cycle are reimbursed on the 1st business day of the following month (e.g., fees from 16 Jun–16 Jul reimbursed on 1 Aug). Note that there might be a small discrepancy in the order of 0.000001 USD which is almost negligible. | | Claiming UI | We will announce a UI for users to claim their borrow fee. | | Example |

• Deposit 10 xBTC

• Borrow 10 000 USDC on 16 Jun

• Borrow fee = 10 USDC during 16 Jun–16 Jul

• 10 USDC becomes claimable on 1 Aug

• If you also post 10 000 APT as collateral, no borrow rebate qualifies.
