As decentralized finance (DeFi) rapidly evolves, lending has emerged as one of its core applications. Within the DeFi lending ecosystem, two primary models dominate: peer-to-peer (P2P) lending and pool-to-pool (Pool) lending. Each model comes with its own strengths and weaknesses, catering to different user needs but also facing unique challenges.

Peer-to-Peer Lending: High Capital Efficiency but Limited Liquidity

P2P lending connects borrowers and lenders directly, delivering a disintermediated financial service. This approach boasts high capital efficiency since funds flow directly to borrowers in need, reducing intermediary costs. However, P2P lending suffers from liquidity constraints. The matching process depends on market supply and demand, which can be unpredictable, resulting in deposited assets potentially earning no interest. Additionally, fixed-term lending adds operational complexity and limits the flexibility of capital use.

Pool Lending: Robust Liquidity but Low Capital Efficiency

In contrast, pool lending aggregates funds from all lenders into a centralized pool, providing excellent liquidity. Borrowers can access funds from the pool anytime, making the lending process more seamless and perpetual. However, this model sacrifices capital efficiency because interest income is shared among all lenders, leading to relatively lower returns for individuals. Moreover, pool lending lacks personalized interest rate settings, often resulting in lower yields compared to P2P lending.

Morpho’s Solution: A Hybrid Approach

To address the shortcomings of P2P and pool lending, DeFi urgently needs an innovative hybrid model. Morpho introduces such a solution, combining P2P and pool lending to optimize capital efficiency and user experience. Built on existing lending pools like Compound, Morpho maintains the same liquidity while seamlessly matching users through a P2P mechanism, increasing the capital utilization of lending pools.

Specifically, Morpho enhances liquidity by allowing borrowers and lenders to match directly, improving capital efficiency. The random matching typical in traditional P2P models is eliminated, significantly improving the user experience. However, P2P matching alone cannot fully address supply-demand imbalances, as there will often be more depositors (n) than borrowers (k). To mitigate this, Morpho has implemented a matching engine that selects k depositors to enjoy P2P annual percentage yields (APY), while the remaining n-k depositors continue earning the standard rates provided by the underlying lending pool.

Security and Advantages

This design ensures that even if users fail to secure a P2P match, Morpho guarantees their returns will at least match those of the underlying lending pools like Compound. This not only enhances lenders’ expected returns but also bolsters the stability and appeal of the entire lending system. By innovatively combining these two models, Morpho achieves higher capital efficiency and improved user experience, laying a solid foundation for the future of decentralized financial ecosystems.

Conclusion

The development of DeFi lending is moving towards greater diversity and efficiency. While P2P and pool lending models each offer unique advantages, no single model can satisfy all user demands. Morpho’s innovative hybrid approach successfully integrates the strengths of both models, enhancing capital efficiency and user experience. As technology continues to advance, we can look forward to more innovative solutions like Morpho, driving DeFi to new heights.
