Cryptocurrency liquidation is a critical mechanism in decentralized finance (DeFi) and leveraged trading that helps maintain system stability—but it can also lead to significant losses for users when market conditions shift rapidly. Over recent months, liquidations have dominated headlines across the crypto space, especially during periods of high volatility. This article explains what liquidation means, why it happens, how protocols manage risk, and what users can do to protect themselves.
Understanding Cryptocurrency Liquidation
In the context of crypto trading and lending, liquidation refers to the forced closure of a leveraged position when the value of a user’s collateral drops below a required threshold. This typically occurs in margin trading or borrowing scenarios where assets are used as collateral to secure loans or open high-leverage positions.

When traders use leverage—essentially borrowing funds to increase their exposure—they must maintain a minimum amount of equity relative to their debt. If the market moves against them and the collateral value declines, they may face a margin call. In DeFi platforms, instead of manual intervention, smart contracts automatically trigger liquidations once predefined thresholds are breached.
For example, if a trader borrows stablecoins using Ethereum (ETH) as collateral and ETH’s price drops sharply, the loan-to-value (LTV) ratio increases. Once it exceeds the maximum allowed LTV, the position is liquidated to prevent further risk to the protocol.
How Do DeFi Protocols Handle Liquidation?
Most major lending protocols—including Aave, MakerDAO, and Abracadabra—have built-in liquidation mechanisms designed to safeguard the system from insolvency. These systems rely on over-collateralization and automated incentives for third-party actors known as liquidators.
Liquidators monitor at-risk positions and execute liquidation transactions when collateral values fall too low. In return, they receive a portion of the collateral at a discount—providing both profit incentive and system resilience.
According to data from Footprint Analytics, on June 18 alone, over 10,208 ETH were liquidated across DeFi platforms due to a sharp drop in ETH’s price, amounting to approximately $424 million in forced sales.
This highlights not only the scale of leveraged exposure in DeFi but also how quickly market downturns can trigger cascading effects.
Case Study: MakerDAO’s Liquidation Mechanism
MakerDAO, one of the oldest and most influential DeFi protocols, offers a clear example of how liquidation works in practice.
The protocol allows users to lock up assets like ETH, USDC, or TUSD as collateral to mint DAI—a decentralized stablecoin. To ensure solvency, MakerDAO requires over-collateralization, with a minimum collateralization ratio of 150%.
Let’s say ETH is priced at $1,500. A user deposits 100 ETH (worth $150,000) and borrows up to $99,999 in DAI. At this point, the collateral ratio is just above 150%, meaning the **liquidation price** is approximately $1,500 per ETH.
If ETH's price falls below that level, the position becomes vulnerable. Once the threshold is breached, the smart contract triggers liquidation: the collateral is sold off (often via auction), and the loan is repaid.
To discourage risky behavior, MakerDAO imposes a 13% penalty fee on liquidated positions:
- 3% goes to the liquidator as reward
- 10% is absorbed by the protocol
This means the original borrower recovers only 87% of their deposited value—if they’re lucky enough to avoid total loss. This punitive structure incentivizes users to actively manage their positions and avoid crossing the red line.
The Ripple Effects of Mass Liquidations
While individual liquidations may seem minor, widespread events can destabilize entire ecosystems. During bear markets, falling asset prices trigger chain reactions:
- More positions get liquidated
- Increased selling pressure drives prices even lower
- Protocols face strain from sudden outflows
- User confidence erodes

One notable case occurred during the stETH depegging event, which severely impacted centralized finance (CeFi) lender Celsius Network. As stETH lost its peg to ETH, Celsius faced massive collateral shortfalls. Unable to meet withdrawal demands, it halted all customer withdrawals—a move that triggered panic and accelerated its collapse.
Compounding the crisis, Three Arrows Capital held substantial debt with Celsius. As Celsius unraveled, so did 3AC’s financial position, ultimately leading to bankruptcy filings and broader contagion across the industry.
These examples illustrate how interconnected DeFi and CeFi systems are—and how liquidation risks extend beyond individual traders.
Impact on Total Value Locked (TVL)
Liquidations directly affect DeFi’s health metrics. As asset values decline and positions are closed out, overall Total Value Locked (TVL) drops significantly.
Footprint Analytics shows that in the past 90 days alone, DeFi TVL fell by 57%, reflecting both price depreciation and user behavior shifts. Many investors preemptively reduce leverage or withdraw funds during downturns to avoid being caught in a liquidation spiral.
Protocols that fail to withstand such stress may experience liquidity crunches, reduced trust, or even insolvency—mirroring risks seen in traditional financial systems.
How to Avoid Being Liquidated
While liquidation is an inherent risk in leveraged finance, there are practical steps users can take to minimize exposure:
- Monitor your LTV ratio: Keep it well below the maximum threshold.
- Use stop-loss orders or hedging tools: Protect against sudden price swings.
- Diversify collateral types: Reduce dependency on a single volatile asset.
- Add more collateral proactively: Especially during volatile periods.
- Choose protocols with higher safety margins: Some platforms offer more forgiving thresholds.
Staying informed and maintaining a conservative approach can help users avoid catastrophic losses—even in turbulent markets.
Frequently Asked Questions (FAQ)
What triggers a cryptocurrency liquidation?
A liquidation is triggered when the value of your collateral falls below a certain threshold relative to your borrowed amount—commonly referred to as the maintenance margin or minimum collateral ratio.
Can I recover my assets after liquidation?
Once liquidated, you typically lose access to your full collateral. Some protocols return a portion (e.g., 87% in MakerDAO), minus penalties paid to liquidators and the platform.
Who are liquidators in DeFi?
Liquidators are individuals or bots that monitor at-risk positions and execute liquidation transactions in exchange for rewards—usually a discount on seized collateral.
Are all DeFi platforms equally risky?
No. Risk varies based on collateral types, loan-to-value ratios, penalty structures, and oracle reliability. Always assess a protocol’s risk parameters before depositing assets.
How do market crashes amplify liquidation events?
Sharp price drops increase the number of undercollateralized positions simultaneously, causing cascading liquidations that further drive down prices—a feedback loop known as a "death spiral."
Is liquidation unique to crypto?
Not entirely. Traditional finance uses margin calls and forced sales too—but DeFi automates the process through smart contracts without human discretion.
Final Thoughts: Navigating Risk in DeFi
👉 Stay ahead of market movements with real-time insights and risk management tools.
Cryptocurrency liquidation is not just a technical feature—it’s a reflection of systemic risk in highly leveraged financial environments. While it protects protocols from default, it also exposes users to sudden losses during volatility.
As DeFi continues to evolve, understanding these mechanisms becomes essential for anyone participating in lending, borrowing, or leveraged trading. By staying vigilant, managing leverage responsibly, and preparing for downside scenarios, users can protect themselves from one of crypto’s most painful experiences: losing assets to automatic liquidation.
Whether you're a seasoned trader or new to decentralized finance, remember: market cycles are inevitable—prudent risk management is your best defense.
