DeFi Lending: How to Borrow & Lend Crypto in the DeFi Market

7/30/2025
DeFi Lending

In traditional finance, getting a loan means dealing with banks, paperwork, and credit checks. Often, you are left waiting days and sometimes weeks for approval. 

In decentralized finance (DeFi) lending works very differently. Thanks to smart contracts and blockchain technology, crypto holders can lend and borrow digital assets directly without needing a middleman. 

After reading this guide, you’ll understand what DeFi lending is, how it works, and how it compares to CeFi lending, including its key advantages and drawbacks. Additionally, you’ll learn what sets Liquidium apart and how to lend your crypto assets using the platform.

TL;DR

  • DeFi lending enables peer-to-peer crypto loans without intermediaries by using smart contracts on blockchains.
  • Liquidium offers a unique cross-chain lending experience where users can deposit bitcoin and borrow assets like USDT on other chains.
  • Interest rates in DeFi are algorithmically adjusted based on demand, and all loans are over-collateralized for safety.

What Is DeFi Lending?

DeFi lending, short for decentralized finance lending, is a peer-to-peer system where crypto holders lend their assets to borrowers without any centralized intermediaries. 

On the other side, borrowers post crypto collateral to gain access to the assets in the lending pool. As with other DeFi operations, blockchain-based smart contracts handle transactions, ensuring transparency and reducing fees.

How Is DeFi Lending Different from CeFi Lending?

In DeFi lending, all borrowing and lending activities are managed by smart contracts on blockchain platforms, removing the need for traditional financial intermediaries like banks. 

By contrast, lending in CeFi (centralized finance) functions more closely to traditional financial models, where banks or institutions act as facilitators, managing lending and borrowing processes.

How Does DeFi Lending Work? 

The DeFi lending process relies on lending pools. Users who wish to offer their crypto for lending deposit a specific amount into these pools, which form a reserve of funds that borrowers can access. 

Transactions are automated and secure, thanks to the smart contracts powering these pools. 

The system allows lenders to contribute their assets to a shared pool, making them readily available for borrowers. In return, lenders earn interest on the assets they have deposited.

Liquidium vs. Aave vs. Compound: A DeFi Lending App Comparison

While Aave and Compound are both pioneers in DeFi lending, both are restricted to Ethereum and EVM-based blockchain ecosystems. 

Liquidium, on the other hand, benefits from its cross-chain capability, which means users can deposit native BTC and borrow stablecoins on other chains without needing to bridge their BTC to another chain beforehand. 

Its ICP-powered backend guarantees speed, decentralization, and a straightforward user experience.

FAQs

What is the best DeFi lender?

There are many different DeFi lending platforms available. For instance, Aave and Compound are established but limited to the Ethereum ecosystem. Meanwhile, Liquidium is ideal if you’re looking for cross-chain lending, Bitcoin-collateralized loans, or more efficient capital usage.

How are interest rates determined in DeFi lending platforms?

Interest rates in DeFi lending are determined by supply and demand dynamics. These, as in the case of Liquidium, can be dynamic interest rate models, where rates shift based on pool utilization. When demand for borrowing rises, rates go up. When it’s low, they drop. This adjustment happens automatically.
