DeFi has changed how we use money. It offers borrowing and lending services without borders or permissions on blockchain platforms. While the benefits of DeFi borrowing—such as instant liquidity and no credit checks—are compelling, they come with a unique set of risks.
Borrowing crypto through DeFi platforms has its challenges. These range from unstable markets to smart contract vulnerabilities. To engage in secure and strategic lending, you need to understand these risks and learn to manage them.
This guide breaks down the key risks involved in DeFi borrowing and equips you with practical methods to minimise them.
As of 2025, billions of dollars in digital assets are locked into DeFi lending protocols like Aave, Compound, and Maker DAO. Borrowers use these platforms to get cash by putting up their crypto as collateral. They often do this without selling their main assets. This model offers speed and flexibility, but it also introduces vulnerabilities.
The open nature of DeFi means:
Grasping these dynamics is vital for anyone serious about using DeFi in their long-term crypto strategy.
DeFi protocols let you borrow money without needing banks. There are no middlemen or paperwork involved. All you need is a wallet and some collateral. This makes DeFi a powerful tool for those in underbanked regions or those seeking financial autonomy.
One of the main reasons users borrow in DeFi is to access liquidity without selling core assets like ETH or BTC. Borrowers can avoid capital gains taxes and keep their long-term exposure. They just need to deposit their holdings as collateral.
Smart contracts manage the lending and borrowing process, making transactions transparent and immutable. You can see interest rates, collateral needs, and repayment terms on-chain. They update in real time.
Maintain a Healthy Collateralization Ratio
One of the most critical aspects of borrowing on DeFi platforms is overcollateralization. If the value of your collateral drops too low relative to your loan, your assets can be automatically liquidated.
Use Stablecoins to Reduce Volatility Risk
Borrowing volatile assets or using them as collateral adds another layer of risk. Instead:
Track Gas Fees and Transaction Speed
In peak network times, gas fees on Ethereum or other chains can spike, delaying your actions or increasing costs. Use layer-2 solutions or lower-fee chains like Arbitrum, Optimism, or Polygon for more efficiency.
Overleveraging in Volatile Markets
Borrowing against crypto means you’re at the mercy of market prices. If your collateral drops and you’re highly leveraged, liquidation can happen fast, and at a loss.
Ignoring Platform Audits
Not all DeFi platforms are created equal. Smaller or newer protocols may offer high interest rates but lack security audits, bug bounties, or a strong user base.
Forgetting to Account for Interest Accrual
Interest on borrowed assets accumulates over time. Some borrowers underestimate how quickly this adds up, especially when borrowing volatile tokens.
Diversify Collateral Types
Don’t rely on a single asset for collateral. If you’re using ETH exclusively and its price drops, your entire position is at risk. Platforms like Aave let you diversify with multiple assets, reducing systemic exposure.
Use Stop-Loss Tools or Automation
Some platforms and wallets allow for automated triggers. These can sell assets or adjust positions if your loan health dips below a certain threshold. Tools like DeFiSaver can help manage positions and avoid liquidation.
Stay Informed with On-Chain Metrics
Use analytics platforms to:
Sites like Dune Analytics and Token Terminal offer real-time dashboards. They show total value locked (TVL), borrowing rates, and collateral details for key lending protocols.
Protocols with active governance and strong token models are generally more resilient. When choosing where to borrow:
Nexus Mutual, InsurAce, and Unslashed provide DeFi insurance. This insurance protects you from smart contract failures and protocol hacks. While not foolproof, it’s an extra layer of security worth exploring for large positions.
DeFi borrowing presents a powerful way to unlock value from your crypto holdings without liquidating them. However, with this power comes responsibility. The decentralised nature of DeFi puts you in control, but also makes you solely accountable.
Successful DeFi borrowers plan carefully. They borrow with a clear purpose and focus on risk management. Stay informed and act with purpose. This way, you can fully benefit from decentralised borrowing while avoiding common pitfalls.
