The current DeFi lending ecosystem faces significant challenges due to fundamental mechanisms employed by major platforms like Aave and Compound:
Key Challenges in Traditional Lending Protocols
- Over-collateralization: Borrowers must deposit assets (e.g., ETH) worth substantially more than their loan amount (typically in stablecoins).
- Volatile interest rates: Rates fluctuate dynamically with supply/demand, often spiking rapidly during high borrowing activity.
- Collateral liquidation: When collateral value falls below critical thresholds (factoring loan amount + interest), assets are forcibly sold to repay debts.
This system creates a critical vulnerability—market crashes trigger cascading liquidations, leading to:
- Spiked interest rates
- Market panic (as seen in recent CRV price collapse)
- Reduced capital efficiency (borrowers over-collateralize to avoid liquidation)
The Innovation: Non-Liquidatable Lending Protocols
This new approach proposes an Ethereum-based lending system with predefined terms, offering simplicity and security:
Core Mechanism
For borrowers:
- Deposit ETH as collateral
- Receive stablecoin loans (e.g., USDC) with zero periodic interest
- Set a custom liquidation price
- Maintain collateral safety if repaid before deadline—even if ETH crashes below liquidation price
For lenders:
- Provide stablecoin liquidity
- Earn ETH staking yields from collateral
- Acquire ETH at predetermined prices if liquidation triggers

How It Works: A Technical Breakdown
The system operates through stablecoin pools (e.g., USDC) with:
- Fixed maturity dates
- Maximum liquidation price ceilings
Borrowers interact with these pools by:
- Selecting preferred liquidation price (below pool ceiling)
- Receiving loan amounts based on collateral value
Example Scenario (ETH price: 2,000 USDC):
| Borrower | ETH Collateral | Liquidation Price | Loan Amount |
|---|---|---|---|
| A | 10 ETH | 1,600 USDC | 16,000 USDC |
| B | 5 ETH | 1,200 USDC | 6,000 USDC |
Key feature: Collateral is only forfeited if ETH price ≤ liquidation price at loan maturity.
Strategic Advantages Over Traditional Systems
Borrower benefits:
- Customizable liquidation buffers
- No forced mid-term liquidations
- Predictable repayment terms
Lender benefits:
- Higher yields than Aave deposits (4.31%-7.98% vs. 2.1%)
- ETH acquisition opportunities at favorable prices

Performance Comparison: New Protocol vs. Aave
| Metric | New Protocol | Aave |
|---|---|---|
| Liquidation Price | Borrower-set (e.g., 1,600 USDC) | Auto-calculated (1,927 USDC) |
| Interest | None | Variable |
| Lender APR | 4.31%-7.98% | 2.1% |
| Collateral Safety | Until maturity | Any price drop |
Potential Future Enhancements
- Real-time liquidations: Allow lenders to acquire ETH at agreed prices during loan terms
- Dynamic pricing: Adjust liquidation thresholds based on market volatility
- Multi-collateral support: Expand beyond ETH to other blue-chip assets
FAQ Section
Q: What happens if ETH price drops below liquidation price before loan maturity?
A: No immediate action occurs—collateral remains safe until the repayment deadline.
Q: How are lender yields calculated?
A: Yields combine ETH staking rewards (e.g., Lido's 4.2% APY) and liquidation premiums.
Q: Can borrowers adjust liquidation prices after loan initiation?
A: Current implementations require fixed terms, but future versions may allow adjustments.
Q: What prevents lenders from withdrawing funds early?
A: Protocol rules prohibit early withdrawals when all USDC in a pool is loaned out.
Conclusion
Non-liquidatable lending protocols address critical DeFi pain points by:
- Eliminating panic-induced liquidations
- Improving capital efficiency
- Offering predictable terms for both borrowers and lenders
This innovation demonstrates how redesigned mechanisms can create more stable and profitable lending environments without sacrificing security.
