The Key Point for Borrowers

Borrowing in decentralized lending protocols opens up exciting possibilities—whether it’s leveraging your crypto assets, funding on-chain activities, or diversifying your portfolio. But with opportunity comes risk, and liquidation is the big one every borrower needs to watch out for. In this blog, we’ll explore what liquidation is, why it matters, and how to manage it effectively to maximize the benefits of borrowing while minimizing potential downsides.

What is Liquidation in DeFi?

Liquidation happens when the value of your collateral drops below a critical threshold—called the liquidation ratio or liquidation threshold. When this occurs, the lending protocol steps in and sells part or all of your collateral to repay the loan, ensuring lenders don’t lose out. It’s an automated safety net for the system, but for borrowers, it can mean losing a chunk of your assets if you’re not prepared.

Key Factors to Understand About Liquidation

To navigate liquidation risk, you need to grasp these core concepts:

1. Health Factor: This is your loan’s safety gauge. It measures how much buffer you have before liquidation kicks in. Here’s the formula:
$$Health Factor= \frac{\text{Collateral Value×Liquidation Threshold}}{\text{Borrowed Amount}}$$

A higher health factor indicates that your loan is safer and less likely to be liquidated. If your health factor drops below 1, you risk liquidation.

2. Liquidation Threshold: Each collateral type (e.g., ETH, BTC, USDC) has its own threshold, set by the protocol. For example, ETH might have an 80% threshold, meaning you can borrow up to 80% of its value before risking liquidation. If your collateral’s value dips too low, you’re on the hook.
3. Price Volatility: Crypto prices can swing wildly. A stablecoin like USDC barely budges, while an altcoin might crash 20% in a day. If your collateral is volatile, even a small dip could tank your Health Factor. Picking the right collateral is key.
4. Liquidation Penalty: If liquidation happens, you don’t just lose collateral—you pay extra. Protocols tack on a penalty (typically 5–15%) to cover costs and discourage risky borrowing. This fee comes out of your collateral, making liquidation sting even more.

How to Avoid Liquidation

Don’t let liquidation catch you off guard. Here are actionable strategies to stay in control:

1. Maintain a Healthy Health Factor

Don’t max out your borrowing limit. Aim for a Health Factor of 2 or higher—borrow only 50–60% of your collateral’s value. This buffer protects you from sudden price drops. What’s “safe” depends on your assets’ volatility, so adjust accordingly.

2. Monitor Collateral Prices

Stay ahead of the curve with tools like CoinGecko or CoinMarketCap. Set price alerts for your collateral to get a heads-up when trouble’s brewing. Many DeFi platforms also have dashboards to track your Health Factor in real time.

3. Diversify Collateral

If the protocol allows, spread your collateral across multiple assets—like ETH, BTC, and a stablecoin. If one tanks, the others might hold steady, keeping your Health Factor intact.

4. Use Stablecoins as Collateral

Stablecoins like USDC or USDT are pegged to fiat (e.g., $1 USD), so their prices don’t rollercoaster like ETH or BTC. Using them reduces volatility risk, making your loan more stable.

5. Top-Up Collateral

See your Health Factor slipping? Add more collateral to boost it. Even a small deposit can push you back into the safe zone.

6. Repay Debt

Pay back part of your loan—especially during shaky markets—to lower your borrowed amount and lift your Health Factor. Every bit helps.

Liquidation Example

Imagine you deposit 2 ETH worth $4,000 as collateral and borrow $1,000 of USDC.

• The Liquidation Threshold for ETH is 80%, and you could borrow up to $3,400 (85% of $4,000) before hitting the limit.
• Your initial health factor is 3.2.
• If ETH drops to $1,000 per ETH, your collateral is now worth $2,000, giving you a new health factor of 1.6—still safe but requiring action if ETH drops further.
• At $625 per ETH, your collateral value is $1,250, causing your health factor to hit 1, which is close to the liquidation threshold. You should consider adding more ETH or repaying some USDC.
• Liquidation Penalty for ETH: 15%. If liquidation occurs at an ETH price of $625, the liquidated amount would be calculated as follows:
$$Liquidated Amount= \frac{\text{Debt Value + (Debt Value * Liquidation Penalty)}}{\text{ETH Liquidated Price}}$$
• Remaining collateral amount = 2 ETH - 1.84 ETH = 0.16 ETH (you still retain the borrowed $1,000 USDC).

Benefits of Borrowing Responsibly

1. Preserve Your Assets: Use your crypto as collateral instead of selling it. Hold onto your ETH or BTC and still tap into liquidity for other moves.
2. Avoid Costly Liquidations: Skip the penalties and losses. A healthy Health Factor keeps your collateral safe and your wallet intact.
3. Maximize Opportunity: Borrowed funds can fuel yield farming, new investments, or portfolio growth—all while keeping your core holdings in play.

Borrowing in DeFi lending protocols is a powerful way to unlock your crypto’s potential, but liquidation is the catch you can’t ignore. By understanding how it works, keeping your Health Factor strong, and using smart strategies, you can borrow with confidence.
