Decentralized finance (DeFi) has revolutionized the way individuals access capital and earn returns, with borrowing protocols at its core. These platforms enable users to lend and borrow digital assets without intermediaries, offering unprecedented financial freedom. However, beneath the promise of high yields and open access lie significant risks that every investor must understand. This article explores the seven major risks associated with borrowing protocols and provides actionable strategies to help investors safeguard their assets in 2025 and beyond.
Understanding the Core Risks in Borrowing Protocols
Borrowing protocols operate on blockchain networks using smart contracts, making them efficient but inherently complex. While they eliminate traditional gatekeepers, they introduce new vulnerabilities. Below are the key risks investors face—each explained with real-world context and mitigation strategies.
1. Smart Contract Vulnerabilities
Smart contracts power all DeFi lending platforms, automating everything from loan issuance to liquidations. However, even a minor coding error can lead to catastrophic losses.

In 2023, several high-profile exploits drained over $100 million from lending protocols due to reentrancy bugs and logic flaws. These vulnerabilities allow attackers to manipulate contract functions and withdraw funds illegitimately.
How to mitigate:
- Only use protocols that have undergone multiple third-party audits (e.g., by firms like CertiK or OpenZeppelin).
- Check for open bug bounty programs, which indicate active security monitoring.
- Monitor community discussions on platforms like GitHub or Discord for red flags.
2. Collateral Volatility Risk
Most borrowing protocols require over-collateralization—users must deposit more value than they borrow. But when crypto prices swing dramatically, collateral values can drop below required thresholds, triggering automatic liquidations.
For example, during the March 2020 "Black Thursday" crash, ETH dropped nearly 50% in hours, causing mass liquidations across MakerDAO and Compound—even as borrowers tried to add more collateral.
Best practices:
- Maintain a healthy loan-to-value (LTV) ratio well below the liquidation threshold (e.g., 50% instead of 75%).
- Use stablecoins as collateral when possible, as they are less volatile.
- Set up price alerts or use decentralized alert services to respond quickly to market moves.
3. Liquidity Risk
Liquidity risk arises when there isn't enough available capital in a protocol to support withdrawals or new loans—especially during periods of market stress.
During the Terra collapse in 2022, users rushed to withdraw funds from various lending platforms, leading to temporary freezes and slippage. Some protocols couldn't meet redemption demands, damaging user trust.
To protect yourself:
- Invest in protocols with deep liquidity pools and high total value locked (TVL).
- Avoid long-term deposits if you anticipate needing quick access to funds.
- Diversify across multiple reputable platforms rather than concentrating funds in one.
4. Governance Risk
Many DeFi protocols claim to be decentralized, governed by token holders who vote on upgrades and parameter changes. But governance attacks—where a single entity accumulates enough voting power—are increasingly common.
In one incident, a whale manipulated governance votes to alter risk parameters on a major lending platform, enabling a flash loan attack that siphoned millions.
Investor safeguards:
- Research how voting power is distributed. Is it concentrated among a few wallets?
- Favor protocols with timelocks and multi-sig controls that delay critical changes.
- Participate in governance yourself if you hold significant tokens.
5. Interest Rate Volatility
Unlike traditional fixed-rate loans, many DeFi lending platforms use algorithmic interest rates that adjust dynamically based on supply and demand.
A sudden surge in borrowing demand can spike interest rates overnight, making loans unaffordable or reducing lender yields unpredictably.
For instance, during NFT booms, demand for ETH loans surged on Aave and Compound, pushing borrowing rates above 20%.
Strategies to manage rate risk:
- Use fixed-rate lending options where available.
- Monitor utilization rates—high usage often precedes rate spikes.
- Consider hedging with interest rate derivatives offered on some DeFi platforms.
6. Regulatory Uncertainty
Governments worldwide are still shaping crypto regulations. Lending protocols may face crackdowns if deemed unlicensed financial institutions or securities issuers.
The SEC’s actions against Compound in 2023 sent shockwaves through the DeFi space, raising fears that yield-generating activities could be restricted or taxed heavily.
Stay ahead by:
- Choosing protocols designed with compliance in mind (e.g., KYC-optional but jurisdiction-aware).
- Staying informed about regulatory developments in your country.
- Keeping detailed records for tax reporting purposes.
7. Market Manipulation
Bad actors can exploit price oracles and liquidation mechanisms to artificially trigger liquidations or inflate asset prices before dumping them.
One infamous case involved attackers manipulating a low-volume token’s price feed to liquidate large positions on a lending protocol, profiting from the resulting chaos.
How to reduce exposure:
- Avoid using obscure or low-market-cap tokens as collateral.
- Prefer protocols that use decentralized oracle networks like Chainlink with multiple data sources.
- Watch for unusual trading volume spikes before committing funds.
Frequently Asked Questions (FAQ)
Q: What is the safest way to start using borrowing protocols?
A: Begin with well-established platforms like Aave or Compound that have strong audit histories and large user bases. Deposit small amounts first and test withdrawals before scaling up.
Q: Can I lose more than I deposit in a DeFi loan?
A: Typically no—if you're borrowing, you can only lose your collateral if it gets liquidated. But if you're providing liquidity or leveraging positions, complex strategies can lead to losses exceeding initial deposits.
Q: Are my funds insured on DeFi lending platforms?
A: Most are not. Unlike traditional banks with FDIC insurance, DeFi lacks formal protection. Some protocols offer community-run insurance pools, but coverage is limited.
Q: How do I track my loan health across multiple platforms?
A: Use portfolio trackers like Zapper or DeBank that integrate with major wallets and show real-time LTV ratios, upcoming liquidation prices, and interest accruals.
Q: Should I trust anonymous development teams behind some protocols?
A: Proceed with caution. While pseudonymity is common in crypto, anonymous teams increase counterparty risk. Prefer projects with transparent roadmaps and doxxed core contributors when possible.

Final Thoughts: Risk Management Is Key
Borrowing protocols offer powerful tools for financial innovation—but they demand responsibility. The key to success lies not in avoiding risk entirely, but in understanding it deeply and managing it proactively.
Diversify your investments, stay informed about technological and regulatory shifts, and always assume that smart contracts can fail. By combining technical awareness with disciplined strategy, investors can navigate DeFi safely and profitably.
Remember: high returns often come with high risk. Prioritize security over yield, and let informed decisions—not hype—guide your journey into decentralized lending.
