Understanding collateralization and liquidation is crucial for safe DeFi borrowing. Let's explore how collateral protects lenders and what triggers liquidations.
Why Over-Collateralization?
DeFi lending requires more collateral than you borrow (typically 150-200%) because there are no credit checks or legal recourse. If you default, the protocol liquidates your collateral to protect lenders.
Collateral = Trust
In traditional finance, your credit score is trust. In DeFi, over-collateralization is trust. The protocol doesn't know youโit only trusts the value locked in the smart contract.

Conservative borrowing with high collateralization
Borrowed $10k with $25k collateral (40% LTV). Large price buffer before liquidation risk.

Liquidation Mechanics
Automated Liquidators
Bots constantly monitor all positions. When health factor < 1.0, they trigger liquidation by repaying your debt and claiming collateral at a discount.
Partial vs Full Liquidation
Most protocols liquidate just enough collateral to bring your health factor back above 1.0 (partial). Some liquidate entire positions (full).
Cost of Liquidation
You lose the liquidation penalty (5-15%) plus any remaining collateral if fully liquidated. Always maintain buffer above liquidation threshold.
Collateral Types & Factors
| Asset | Max LTV | Liq. Threshold | Liq. Penalty | Risk Level |
|---|---|---|---|---|
| ETH | 82.5% | 86% | 5% | Low |
| wBTC | 75% | 80% | 6.25% | Low |
| USDC | 87% | 89% | 4.5% | Very Low |
| LINK | 70% | 75% | 10% | Medium |
| Small Cap Alt | 50% | 60% | 15% | High |
Best Practices to Avoid Liquidation
- โขKeep health factor >1.5 at all times (2.0+ for safety)
- โขSet price alerts for your collateral assets
- โขDon't max out borrowing capacityโleave buffer room
- โขUse stablecoins as collateral for lower volatility
- โขMonitor position daily during volatile markets
