Automatically Minimize Your DeFi Borrowing Costs!

The problem RateHopper solves

RateHopper is a loan aggregator for borrowers in DeFi which addresses several key problems faced by individuals and investors borrowing digital assets on DeFi platforms:

  1. Fluctuating Interest Rates: Borrowing interest rates in DeFi can change with every new block due to shifts in supply and demand. This volatility makes it hard for users to predict and manage their borrowing costs effectively.

  2. Time-Consuming and Complex Management: Manually tracking rates across numerous money market protocols, and various like-assets (e.g., USDC, USDT, DAI) is a significant burden. Newer protocols like Morpho further increase this complexity with hundreds of distinct lending/borrowing markets.

  3. Increased Borrowing Costs: Without diligent and active management, users often end up paying higher interest rates than necessary, leading to increased overall borrowing expenses.

  4. Lack of Clarity on Borrowing Costs: Users often don't have a clear picture of how much they've spent on borrowing over time. This information is crucial, especially as borrowing costs can be tax-deductible in some jurisdictions.

RateHopper's Solution: By identifying and facilitating switches to lower-rate positions, RateHopper directly helps users minimize their interest payments. RateHopper automates the process of finding the optimal (lowest) borrowing rates. In V1, it will show users their historical rates and generalized rates, allowing them to manually switch. V1 also aims to introduce automation for switching based on user-defined criteria. Finally, we will provide a dashboard showing a user’s historical borrowing rates and the total interest paid over time, offering much-needed clarity.

We believe that as Decentralize Finance gains mainstream adoption, a product that automatically ensures the best rates for borrowers would be very important. Loan aggregation in the traditional finance space is a big market. Aggregators receive a commission from lenders for each loan originated through their platform. In some markets, for a $500,000 loan, aggregators might receive an upfront commission of 0.61% (about $3,100) and a trailing commission of 0.18% per year (about $900 annually. The global loan aggregator market was valued at approximately $7.2 billion in 2024, with a projected compound annual growth rate (CAGR) of 15.71% from 2025 onward.

Challenges I ran into

There were a few challenges:

  1. Gathering and maintaining accurate, real-time, and historical lending pool rates from various DeFi protocols across different markets is complex. Infrastructure issues with RPCs were part of the issue.

  2. Our smart contract for switching between protocols had to call different lending protocols and there is no standards when it comes to borrowing and repaying so we needed different adapters for each protocol
