| Section               | Key Points                                                                                                                                                                                                                                                          |
| --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Eligibility           | <p>• Wallet supplies xBTC only as collateral </p><p>• Borrows USDC or APT exclusively </p><p>• Adding any other asset as collateral voids eligibility </p><p>(work-around: open a separate profile for mixed collateral)</p>                                        |
| Fee flow              | <p>• Borrow fees accrue and are charged in real time </p><p>• We track them for 30-day cycles starting 16 Jun → 16 Jul, 16 Jul → 16 Aug, etc.</p>                                                                                                                   |
| 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               | <p>• Deposit 10 xBTC </p><p>• Borrow 10 000 USDC on 16 Jun </p><p>• Borrow fee = 10 USDC during 16 Jun–16 Jul </p><p>• 10 USDC becomes claimable on 1 Aug </p><p>• If you also post 10 000 APT as collateral, no borrow rebate qualifies.</p>                       |
