Liquidation is one of the most painful experiences in DeFi. You deposit collateral, borrow against it, and if the market moves against you, your position gets automatically closed — at a loss — to repay the borrowed amount. No warnings, no grace period. Just a transaction that takes your collateral.
On Solana, the three main lending protocols — Kamino Finance, MarginFi, and Save (formerly Solend) — all have automated liquidation systems. Understanding how they work is essential before borrowing a single dollar.
This guide explains liquidation mechanics, how to monitor your position, and the strategies to keep yourself safe.
What Is a Liquidation?
When you borrow in DeFi, you deposit collateral worth more than what you borrow. The ratio between your collateral value and your loan is called your health factor (or collateral ratio).
If the value of your collateral drops (or your loan value rises, as with variable rates), your health factor deteriorates. When it hits the liquidation threshold, a liquidator — an automated bot or user — steps in:
- They repay part of your debt
- They receive your collateral at a discount (the liquidation bonus or liquidation penalty, typically 5-15%)
- Your position is partially or fully closed
Example:
- You deposit $10,000 SOL as collateral
- You borrow $5,000 USDC (50% LTV)
- SOL price drops 40%, making your collateral worth $6,000
- Your LTV is now 83%, above the liquidation threshold of ~80%
- A liquidator repays $3,000 of your USDC debt
- They receive $3,300 of your SOL (10% bonus)
- You keep the remaining SOL after liquidation
You've lost value, paid the liquidation penalty, and still have remaining debt. The message: liquidation is expensive.
How Each Protocol Handles Liquidations
Kamino uses a health factor system (similar to Aave on Ethereum). Your health factor is displayed prominently in the dashboard.
- Health factor = 1.0: Exactly at the liquidation threshold. You will be liquidated immediately
- Health factor > 1.5: Relatively safe for short-term holds
- Health factor > 2.0: Comfortable buffer for most market conditions
Kamino supports multiple assets as collateral including SOL, JitoSOL, USDC, USDT, and various LP tokens. Each asset has its own collateral weight and liquidation parameters based on its volatility and liquidity.
Kamino's Multiply feature (leveraged staking) is a common source of liquidations — users who lever up JitoSOL against SOL borrowing can get liquidated if the liquid staking token depeg exceeds the buffer.
MarginFi uses a risk engine that monitors positions in real time. The platform shows your account health as a percentage:
- 100%: Maximum safety
- Below 20%: Getting close to liquidation territory
- 0%: Liquidation
MarginFi allows both isolated and cross-margin positions. In cross-margin mode, all your positions are combined into one health calculation — which can be efficient but means one bad position can affect all your collateral.
Save (formerly Solend)
Save is one of the oldest Solana lending protocols. It displays a utilization ratio and borrow limit rather than a health factor, but the mechanics are the same: if your borrowed value exceeds the liquidation threshold relative to collateral, liquidators can act.
Save has separate pools (Main, Turbo, Isolated) with different risk parameters. Isolated pools for smaller tokens carry higher liquidation risk due to thinner liquidity.
Key Terms to Know
| Term | Definition |
|---|
| LTV (Loan-to-Value) | Your loan amount divided by collateral value |
| Max LTV | Maximum LTV allowed before borrowing is restricted |
| Liquidation Threshold | LTV at which liquidation becomes possible |
| Liquidation Penalty | Discount liquidators receive on your collateral (typically 5-15%) |
| Health Factor | Score showing distance from liquidation (higher = safer) |
| Collateral Weight | How much borrowing power an asset provides (e.g., 80% for SOL) |
How to Monitor Your Health Factor
On Kamino
Your health factor is shown in the dashboard next to your position. A color-coded bar indicates safety:
- Green (>2.0): Safe
- Yellow (1.5-2.0): Monitor
- Orange (1.0-1.5): Danger zone
- Red (<1.0): Liquidation imminent
On MarginFi
Account health percentage is shown on the main dashboard. Enable browser notifications in your profile settings to get alerted when health drops below a threshold.
Third-party monitoring tools
- Step Finance: Shows your DeFi positions including lending/borrowing health across protocols
- Sonar Watch: Portfolio tracker with lending position monitoring
- Birdeye: Set price alerts for your collateral assets — if SOL drops 10%, you want to know immediately
For critical positions, set up price alerts for your collateral asset on Birdeye so you receive a notification if price drops toward your liquidation level.
