In a Lending Protocol, What is the Maximum Percentage?

Explore the intricacies of maximum percentages in DeFi lending protocols. Discover how these figures are determined and how they impact borrower behavior in the crypto space.

Understanding Lending Protocols

Lending protocols are part of the Decentralized Finance (DeFi) ecosystem, which empowers individuals to lend, borrow, and earn interest on digital assets directly on the blockchain. A key component of these protocols involves defining the maximum percentage designated for loans, interest rates, and other financial aspects.

Factors Determining the Maximum Percentage

Several key factors influence the maximum percentage in a lending protocol.

  • Collateralization Ratio: This ratio determines the maximum amount a lender can borrow against their collateral.
  • Interest Rate Models: These models decide the variation in interest rates based on supply and demand dynamics.
  • Liquidity: The availability of funds in the lending pool also affects the maximum percentage.

Determining the Maximum Percentage in Protocols

Each lending protocol stipulates its own maximum percentage based on the aforementioned factors. Existing protocols such as Compound Finance, Aave, and MakerDAO all employ different models to calculate this figure.

Case Study: Compound Finance

Compound Finance, for instance, utilizes a collateral factor for each asset. The factor which ranges between 0 and 1 is multiplicative, limiting the maximum amount that can be borrowed. For example, if a user supplies $100 worth of Ether (ETH) on Compound as collateral and the collateral factor for ETH is 0.75, the maximum they can borrow is $75.

Implications of the Maximum Percentage

The maximum percentage in lending protocols possesses significant influence over lending and borrowing behaviors within the DeFi ecosystem. It can affect the total value locked (TVL) in the protocol, borrowing rates, and the overall risk and stability of the protocol.


In conclusion, the maximum percentage in a lending protocol undertakes a pivotal role within the DeFi space. Investors and users of these protocols should have a clear understanding of how maximum percentages are determined to make informed and responsible financial decisions on the blockchain.
