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.
