Decentralized Finance (DeFi) has revolutionized traditional financial systems by leveraging blockchain’s transparency, immutability, and programmability. Pioneering protocols like Compound and Aave laid the foundation with overcollateralized lending, attracting billions in deposits through liquidity mining incentives. As of mid-2025, Aave holds over $16.5 billion in total deposits, while Compound surpasses $13 billion.
However, overcollateralization limits capital efficiency and exposes users to liquidation risks—major pain points in user experience and scalability. To address these limitations, a new wave of DeFi innovation is emerging: undercollateralized lending. By blending on-chain execution with off-chain credit evaluation and legal enforceability, protocols like Maple Finance, TrueFi, and Goldfinch are bridging the gap between decentralized finance and real-world finance.
This article explores how these platforms enable non-full collateral loans, their unique mechanisms, risk models, and the future of credit in DeFi.
The Problem with Overcollateralization
In traditional DeFi lending, users must deposit more value than they borrow—often 150% or higher. For example, MakerDAO requires at least 150% collateralization for DAI loans. While this ensures protocol safety, it sacrifices capital efficiency.
Undercollateralized lending flips this model: borrowers can access funds with little or even zero collateral, relying instead on creditworthiness, reputation, and legal agreements. This mirrors traditional unsecured loans but executes them in a decentralized environment.

Maple Finance: Agent-Based Credit Risk Management
Maple Finance is a decentralized corporate credit market that enables undercollateralized loans through a unique agent-based governance model.
Instead of relying solely on smart contracts, Maple introduces trusted third parties called Pool Delegates—experienced asset managers who create and manage lending pools. These delegates conduct due diligence on institutional borrowers such as hedge funds, market makers, exchanges, and miners.
Key Roles in Maple
Pool Delegates
Delegates are vetted by Maple’s governance and approved before launching a pool. They:
- Define underwriting criteria
- Assess borrower creditworthiness
- Negotiate loan terms
- Monitor repayments
- Handle default resolution
In return, delegates earn performance fees and management incentives, aligning their interests with lenders.
Liquidity Providers
Users deposit stablecoins (e.g., USDC) into vetted pools to earn fixed yields plus MPL token rewards. However, liquidity is locked for 180 days (pre-unstaking period), followed by a 10-day cooldown before withdrawal.
This lock-up ensures capital stability during loan duration.
Borrowers
Institutions receive fast, transparent financing without liquidation risk. Crucially, Maple enforces legal agreements via OpenLaw or similar frameworks—meaning defaulters face not just reputational damage but legal consequences.
Stakers (Insurance Providers)
MPL holders can provide insurance by staking their tokens via Balancer liquidity pools (MPL/USDC). In exchange, they earn a share of interest income—but also bear loss exposure if defaults occur.
Currently, Maple hosts two active pools managed by Orthogonal Trading and Maven 11, with over $58 million in total deposits. Some pools offer stablecoin yields exceeding 40%, reflecting high demand for institutional-grade crypto credit.
TrueFi: Community-Governed Unsecured Lending
Launched by the team behind TUSD (TrustToken), TrueFi offers another approach to undercollateralized lending—this time governed directly by its community.
TrueFi uses a credit scoring system (scale: 0–255) based on:
- Company background
- Financial health
- Transaction history
- Assets under management
- Repayment track record
Each loan request is voted on by TRU stakers. Approval requires:
- At least 80% support
- Minimum 15 million TRU tokens participating in the vote
This decentralized underwriting model removes intermediaries while maintaining accountability.
To date, TrueFi has facilitated around **$220 million in loans**, with an average loan size of $5.1 million and term of 52 days. Notable borrowers include Amber Group, Alameda Research, and Poloniex—all subject to legal recourse in case of default.
TrueFi demonstrates that decentralized governance can effectively assess credit risk—without relying on centralized agents.

Goldfinch: Expanding Financial Inclusion Globally
While Maple and TrueFi focus on institutional borrowers, Goldfinch aims higher—and broader. Its mission? To bring undercollateralized lending to underserved markets in developing economies.
Goldfinch targets "long-tail" borrowers excluded from traditional banking due to high underwriting costs or lack of formal credit history. Imagine a small business owner in Bogotá needing funds to buy motorcycles for delivery workers—banks may reject them, but Goldfinch enables global lenders to step in.
How It Works
- No collateral required
- No native governance token (as of now)
- Anyone with credit assessment skills can join the Backer program
- Loans funded across countries like India, Indonesia, Nigeria, Mexico, and Vietnam
Backers evaluate borrower applications using local knowledge and data. If a loan defaults, originators (local partners) share liability—a mechanism designed to ensure skin in the game.
Since launch, Goldfinch has deployed over $4.5 million in loans worldwide. Backed by investors like a16z and Coinbase, it represents a bold experiment in decentralized global credit.
However, scaling this model poses challenges: regulatory uncertainty, cross-border enforcement, and higher default risks compared to institutional lending.
Other Notable Projects
yborrow.finance – Credit Delegation on Aave
Aave’s credit delegation feature allows depositors to lend their unused borrowing power (via aToken) to others. For instance, DeversiFi obtained an unsecured loan using delegated credit—backed by an automated legal agreement via OpenLaw.
This innovation unlocks dormant capital within DeFi protocols.
Wing – Cross-Chain Credit for Individuals
Wing offers KYC-based credit lines on a cross-chain platform. Users complete identity verification to access small loans (typically $20–$400). Though currently underutilized—with only $50K deposited per asset class—it showcases the potential for personal credit scoring in DeFi.
Advantages of Undercollateralized Lending
✅ Higher capital efficiency – Borrowers use credit instead of tying up assets
✅ No liquidation risk – Unlike overcollateralized loans
✅ Legal enforceability – Real-world contracts back most protocols
✅ Integration with insurance mechanisms – E.g., staking-based loss coverage
✅ Scalable risk assessment – Through agents, voting, or community evaluation
Risks and Limitations
⚠️ Default risk remains – Especially with long-tail borrowers
⚠️ Limited liquidity for lenders – Lock-up periods reduce flexibility
⚠️ Access restrictions – Not all users qualify as borrowers or delegates
⚠️ Legal complexity – Jurisdictional challenges in cross-border enforcement
FAQ: Understanding Undercollateralized Lending
Q: What is undercollateralized lending?
A: It allows borrowers to take loans with less collateral than the loan value—sometimes zero—based on creditworthiness rather than asset backing.
Q: How do lenders get repaid if there's no collateral?
A: Repayment relies on borrower reputation, legal agreements, and sometimes insurance pools or delegate accountability.
Q: Is undercollateralized lending safe for investors?
A: It carries higher risk than overcollateralized models. However, due diligence, legal recourse, and staking mechanisms help mitigate losses.
Q: Can individuals borrow from these platforms?
A: Most current protocols target institutions. Goldfinch and Wing are exceptions aiming at retail or emerging-market users.
Q: Are these loans enforced legally?
A: Yes. Platforms like Maple and TrueFi use legal contracts (e.g., via OpenLaw) to enable real-world enforcement against defaults.
Q: How does this differ from traditional DeFi lending?
A: Traditional DeFi relies purely on code and overcollateralization. Undercollateralized lending integrates off-chain trust layers—credit checks, legal frameworks, and human judgment.
Final Thoughts: The Future of Credit in DeFi
Undercollateralized lending marks a pivotal evolution—where DeFi stops mimicking traditional finance and starts innovating beyond it. Protocols like Maple, TrueFi, and Goldfinch prove that trustless systems can incorporate real-world trust elements without sacrificing decentralization.
As these models mature, we may see:
- Wider adoption of decentralized credit scoring
- Interoperable reputation systems across chains
- Integration with identity solutions (DID)
- Hybrid risk models combining AI analysis with community voting
The fusion of blockchain efficiency with real-world accountability isn’t just possible—it’s already happening.
