Lenfi: A New Era in Decentralized Finance on the Cardano Blockchain

What is Lenfi?

Lenfi, built on the Cardano blockchain, represents a significant advancement in decentralized finance (DeFi). Emerging from Aada Finance, it introduces a unique blend of peer-to-peer and peer-to-pool lending through its integration of Aiken smart contracts. Central to Lenfi’s ecosystem is the LENFI token, serving both as collateral for borrowing and a tool for governance, allowing token holders to directly influence the platform’s direction. Committed to transparency, Lenfi maintains clear visibility of its treasury and token circulation, positioning itself as a practical and user-driven solution in the DeFi space.

LenFi Decentralized Lending and Borrowing

Now, let’s dive in!


Lenfi distinguishes itself from the norm with a unique approach to lending and borrowing, free from custodial control. At the helm of this innovation is Mantas, the lead developer, whose vision and expertise have been pivotal in shaping Lenfi’s trajectory.

Lenfi offers a fresh perspective on DeFi, diverging from traditional Ethereum-based protocols by harnessing Cardano’s Extended Unspent Transaction Output (EUTXO) model.

This choice is not just technical but strategic, allowing Lenfi to provide enhanced security and efficiency, crucial elements in today’s digital finance landscape. The platform, which transitioned from its initial avatar as Aada Finance, has been instrumental in introducing peer-to-peer lending on Cardano since September 13, 2022. The upcoming pooled lending protocol aims to position Lenfi as a comprehensive solution for decentralized loans.

One of Lenfi’s standout features is its ability to empower depositors with liquidity options. Users can deposit funds under specific conditions or contribute to liquidity pools, enhancing their financial strategies. This flexibility extends to various trading strategies like shorting, longing, and yield farming, while also enabling users to earn interest. The introduction of pooled lending is set to further expand these possibilities, offering seamless and trustless borrowing along with decentralized liquidations.

The decision to launch on Cardano was driven by the blockchain’s agnostic architecture and the potential for a fair start in the summer of 2021, just before the Alonzo hardfork. This timing allowed the team to thoroughly understand and leverage the EUTXO model. Mantas and his team, including co-founder Ruslan Soluyanov and other key members like Micah Kendall and Lukas Armonas, have been instrumental in fostering a community-driven approach, maintaining a commitment to decentralization and transparency. Their goal is not just to make an impact within the Cardano community but to set a trend on a global scale.

The Technology Behind Lenfi

Lenfi’s technology framework, evolving from the foundational Aada Finance protocol, integrates advanced P2P lending and borrowing mechanisms within the Cardano blockchain’s robust ecosystem. At its core, Lenfi employs V1 smart contracts developed in Aiken, a strategic move that significantly enhances the platform’s functionality and security.

The primary innovation in Lenfi’s approach is the flexibility it offers in lending and borrowing. Users engage in P2P transactions where they can define customized loan terms. This feature brings a personalized touch to DeFi transactions, allowing for tailored financial solutions that meet diverse user needs.

  1. Liquidity Requests and Deposits:
    • Borrowers initiate liquidity requests by submitting overcollateralized loan applications with specific terms like loan amount, collateral tokens, duration, and interest rate. Once submitted, these requests lock the collateral in a smart contract, safeguarding it until the loan is repaid or liquidated.
    • On the flip side, liquidity deposits (lender requests) enable lenders to offer funds with custom terms. Lenders lock these funds in smart contracts, making them available for borrowers who agree to the pre-set conditions, thus creating a seamless lending process.
  2. Operational Scenarios:
    • If a borrower repays the loan, the lender receives the principal plus interest.
    • Should the Health Factor of a loan drop below a certain threshold, the lender has the option to liquidate the loan, receiving the collateral tokens and a commission fee.
    • In the event of a borrower’s failure to repay, the lender is entitled to the full collateral.
  3. NFT Bonds and Market:
    • Lenfi introduces NFT Bonds, allowing borrowers to list their bonds on the marketplace. This feature provides an option to recoup part of the collateral, adding a layer of flexibility in loan management.
  4. Security and Transparency:
    • Lenfi’s commitment to security is evident in its rigorous smart contract audits and the transparent, immutable nature of its operations on the Cardano blockchain.
    • The protocol operates without a kill switch, ensuring continuous access to funds, and employs thorough measures for liquidations, including penalties and requirements for adequate collateralization, to maintain stability and fairness in the system.
