Cryptocurrency lending has become a cornerstone of decentralized and centralized finance, offering users flexible ways to unlock liquidity without selling their digital assets. One popular implementation of this service is the crypto collateral lending model — a system where users pledge their crypto holdings to borrow stablecoins or other digital currencies. This guide explores how crypto lending works, the differences between fixed-term and flexible lending options, and how to get started safely and efficiently.
Whether you're looking to cover short-term expenses, leverage your holdings for yield-generating strategies, or diversify your investment approach, understanding the mechanics of crypto-backed loans is essential.

Understanding Crypto Collateral Lending
Crypto collateral lending allows users to borrow digital assets by locking up other cryptocurrencies as collateral. This process is non-custodial in many cases, meaning users retain ownership while gaining access to funds. The core principle behind this model is “Borrow to earn, borrow to spend” — enabling users to maintain exposure to their long-term investments while using borrowed funds for active financial strategies.
For example, a user holding Bitcoin (BTC) can pledge it as collateral to borrow USDT (a stablecoin), which can then be used for everyday spending, trading, or investing in high-yield opportunities like staking, liquidity pools, or initial token offerings.
This method provides liquidity without triggering taxable events that would occur from selling crypto outright — a major advantage for long-term holders.
Types of Crypto Lending: Fixed-Term vs. Flexible Loans
There are two primary models in crypto lending: fixed-term lending and flexible (on-demand) lending. Each serves different financial needs and risk appetites.
Fixed-Term Lending
Fixed-term lending offers borrowers a predetermined loan period with a fixed interest rate. This structure ensures predictable repayment terms and shields users from sudden rate fluctuations.
- Supported borrowable assets: USDT, BTC, ETH, OKB
- Supported collaterals: BTC, ETH, FIL, LTC, and over 10+ other major cryptocurrencies
- Funding source: Investor pools from fixed-income yield products
Benefits:
- Lower interest rates compared to flexible loans
- Faster funding due to pre-allocated capital
- Ideal for medium- to long-term financing needs
Interest is calculated daily:
Interest = Borrowed Amount × Daily Interest Rate × Loan Duration
(Loan duration starts on the day of disbursement; partial days count as full days.)
Early repayment is allowed but comes with conditions:
- Interest is charged based on actual borrowing days
- A penalty equal to 50% of the remaining term’s interest is applied to compensate investors
This model suits users who want stability and are confident in their repayment timeline.
Flexible (On-Demand) Lending
Flexible lending offers no fixed term and variable interest rates, updated hourly. It gives users maximum control over when and how much they repay.
- Over 120+ supported collateral types
- Instant borrowing and on-demand repayment (partial or full)
- Funds sourced from liquid wealth management products like “余币宝” (flexible savings pools)
Interest is recalculated every hour:
Hourly Interest = (Principal + Accrued Interest) × Hourly APY / 365 / 24
This model is ideal for traders or short-term financiers who need quick access to capital and plan to repay quickly.

Risk Management: Collateral Ratios and Liquidation
Managing risk is crucial in crypto lending. Two key metrics determine your loan’s safety: initial collateral ratio, warning level, and liquidation level.
What Is Collateral Ratio?
The collateral ratio measures the value of your pledged assets against your outstanding debt (including accrued interest):
Collateral Ratio = (Loan Amount + Interest) / Collateral Value
Different assets have different initial collateral requirements. For example, more volatile coins may require higher collateralization (e.g., 150%), while stablecoins might allow lower ratios.
Warning and Liquidation Levels
- When your collateral ratio exceeds the warning threshold, you’ll receive a notification prompting you to deposit more collateral or repay part of the loan.
- If the ratio reaches the liquidation threshold, the platform will automatically sell part or all of your collateral to repay the debt.
This mechanism protects both users and lenders from market volatility risks.
Regular monitoring of your position — especially during sharp price movements — is strongly recommended.
Frequently Asked Questions (FAQ)
Q: Can I repay my loan early?
Yes. For flexible loans, you can repay partially or fully at any time. Partial repayments are applied first to accrued interest, then to principal. Fixed-term loans allow early repayment but charge a penalty equal to 50% of the remaining interest owed to investors.
Q: What happens if my collateral value drops suddenly?
If the value of your collateral falls sharply, your collateral ratio increases. Once it hits the warning level, you’ll be alerted. If it reaches the liquidation level, your assets will be sold automatically to cover the debt.
Q: Which assets can I use as collateral?
Over 120 cryptocurrencies are accepted, including BTC, ETH, LTC, FIL, and many altcoins. Stablecoins often offer better loan terms due to lower volatility.
Q: How fast does the loan get approved?
Loans are typically approved instantly after submission, with funds available within minutes.
Q: Is there a minimum or maximum loan amount?
Minimum amounts vary by asset type and platform policy. Maximum borrowing depends on your collateral value and the asset’s loan-to-value (LTV) ratio.
Q: Can I use borrowed funds for staking or yield farming?
Absolutely. Many users borrow stablecoins to participate in staking programs, Jumpstart campaigns, or other yield-generating activities — effectively leveraging their holdings for additional returns.
