Introduction to Service Fee Credit
BitFuFu's "Service Fee Credit" feature is essentially an output-based crypto-backed lending service. It provides users with a flexible, convenient, and low-interest method to pay service fees, ensuring your hashrate continues running during periods of capital turnover to maximize mining returns.
What is Service Fee Credit?
The Service Fee Credit feature allows the system to automatically advance (lend) 3 days worth of service fees whenever your plan's remaining service fee balance drops below 3 days. Once enabled, the mining output from that specific hashrate will be automatically directed to your Collateral Account to serve as backing for the loan.
Activation Requirements:
- The product must support service fee installments and have service fees pending payment.
- The size of a single hashrate order must be ≥ 2000T.
- The remaining operational days of the hashrate plan must be ≥ 30 days.
- The initial prepaid service fee duration at the time of ordering must be ≥ 10 days.
Core Advantages & Operations
- Auto-Renewal to Prevent Downtime: The system automatically detects balances and advances fees, completely eliminating the risk of hashrate suspension due to forgotten payments.
- Flexible Toggle: You can check the box to enable this feature when placing your order, or batch enable/disable it at any time during the hashrate's runtime via the "Service Fee" page.
- Low Interest Rates: Interest fees are calculated monthly (e.g., a monthly rate of 0.67%). Interest accrued on the outstanding principal from the previous month is settled on the 4th of every month.
Loan-to-Value (LTV) Management & Risk Control
LTV (Loan-to-Value) ratio is the core metric used to assess your borrowing risk:
LTV=Collateralized Coins×Real-time Coin PriceService Fee Installment Principal+Interest
The system manages risk across four critical LTV thresholds:
LTV Level | Status | Description | System Action / User Advice |
< 50% | Withdrawable | Collateral is highly sufficient. | You can withdraw the portion of collateralized coins that keeps the LTV below 50% at any time. |
< 70% | Normal Lending | The system operates normally. | Auto-loans will successfully trigger to pay fees whenever the remaining service fee balance drops below 3 days. |
≥ 80% | Warning Line | The system triggers an alert. | Strongly recommended to immediately top up collateral or repay the loan to lower your LTV. |
≥ 90% | Liquidation Line | System executes immediate liquidation. | The system liquidates collateral to repay the loan and charges a 2% liquidation fee. Service Fee Installments for all hashrates will be turned off. |
How to Repay Loans and Withdraw Collateral?
- Active Repayment: Go to "Dashboard - Service Fee Credit" and click "Repay" at any time. We support repayment using FUFU Points, USDT transfers, or direct deduction from your collateral (calculated at real-time coin prices). Repayments are applied to interest first, then to the principal.
- Withdrawing Collateral: When LTV < 50%, you can withdraw excess collateral by clicking "Adjust LTV" (an on-chain network transaction fee of 0.0005 BTC will be deducted).
