Decentralized finance (DeFi) has transformed how individuals interact with financial services, eliminating intermediaries and enabling peer-to-peer lending, borrowing, and earning. At the forefront of this revolution stands Compound Finance, one of the earliest and most influential DeFi lending protocols. Since its launch, it has become a cornerstone of the DeFi ecosystem, offering users a secure, transparent, and permissionless way to earn interest on crypto assets or borrow against them.
This article breaks down the fundamentals of Compound Finance—how it operates, its core components, key benefits, and why it remains a top choice for crypto investors and traders in 2025.
Understanding Compound Finance
Founded by Robert Leshner and Geoffrey Hayes, alumni of the University of Pennsylvania, Compound Finance emerged from a vision to democratize access to financial tools using blockchain technology. The duo previously co-founded Safe Shepherd, an identity protection service, before turning their focus to decentralized systems.
Today, both serve as executives at Compound Labs, the development team behind the protocol. Leshner acts as CEO, while Hayes serves as CTO. Together, they oversee not only Compound Finance but also Compound Treasury, a product designed to help traditional financial institutions gain exposure to DeFi yields in a compliant manner.
At its core, Compound Finance is a decentralized lending and borrowing protocol built on smart contracts. Originally launched on Ethereum, it now supports multiple blockchains, including Arbitrum, Optimism, and Polygon, increasing accessibility and reducing transaction costs for users.

How Does Compound Finance Work?
Compound operates through automated liquidity markets, where users can supply digital assets to earn interest or borrow assets by posting collateral. The entire process is governed by open-source smart contracts—removing the need for central authorities or credit checks.
The protocol currently runs on three versions—v1, v2, and v3—with each iteration introducing improved efficiency, enhanced risk controls, and broader asset support. v3, in particular, introduces dynamic risk parameters and flash loans without requiring collateral under specific conditions.
Lending Crypto Assets
When users lend crypto on Compound, their assets are deposited into a shared liquidity pool. In return, they receive cTokens (e.g., cETH for Ethereum, cDAI for DAI), which represent their share of the pool and accrue interest over time.
Interest rates are algorithmically determined based on supply and demand dynamics within each market. As more people borrow a specific asset, its borrowing rate increases—providing higher yields for lenders. These earnings compound automatically, meaning users earn interest on both their principal and accumulated interest.
Lenders also gain the ability to use their supplied assets as collateral for borrowing other supported tokens, subject to a collateral factor—typically up to 85%, depending on the asset’s stability and liquidity.
Borrowing Crypto Assets
To borrow funds, users must first deposit eligible collateral. The amount they can borrow depends on:
- The value of their deposited assets
- The collateral factor assigned to those assets
- Current market conditions
For example, if ETH has a collateral factor of 75%, a user depositing $1,000 worth of ETH can borrow up to $750 worth of another asset like DAI or USDC.
However, borrowers must maintain a healthy health factor. If the value of their collateral drops too low—due to market volatility—they risk being liquidated. Liquidation allows other users or bots to repay part of the loan in exchange for a discount on the collateral, helping maintain system solvency.
COMP Token: Governance and Incentives
COMP is the native governance token of Compound Finance, issued as an ERC-20 token on Ethereum. It plays a crucial role in decentralizing control over the protocol.
Users earn COMP tokens simply by supplying liquidity or borrowing assets. Rewards are distributed approximately every 15 seconds, aligning with Ethereum’s block time.
Holders of COMP can:
- Submit governance proposals
- Vote on changes to interest rates, supported assets, or risk parameters
- Influence protocol upgrades and revenue models
This decentralized governance model ensures that the community—not a centralized team—shapes the future direction of Compound.

Key Benefits of Using Compound Finance
Wide Range of Supported Assets
Compound supports major cryptocurrencies such as ETH, WBTC, DAI, USDC, and others, allowing users flexibility in managing their portfolios. Each asset operates within its own liquidity market, ensuring efficient price discovery and stable operations across different token types.
Decentralized & Permissionless Access
There are no sign-ups, credit checks, or minimum balances required. Anyone with a Web3 wallet can connect to Compound and begin lending or borrowing instantly—making it accessible to users globally, especially in regions underserved by traditional banking.
This permissionless nature empowers financial inclusion and aligns with the foundational principles of blockchain: transparency, autonomy, and openness.
High Security Standards
Security is paramount in DeFi, and Compound has established itself as one of the most trusted protocols. It has undergone rigorous audits by leading firms such as Trail of Bits and OpenZeppelin, with no major exploits reported since inception.
Additionally, its open-source codebase allows continuous community review, further enhancing reliability and trust.
According to data from DeFiLlama, Compound maintains a total value locked (TVL) of over **$2.5 billion** across all chains—a testament to sustained user confidence despite market fluctuations. At its peak in late 2022, TVL exceeded $12 billion during a strong bull cycle.
Frequently Asked Questions (FAQ)
Q: Is Compound Finance safe to use?
A: Yes, Compound is considered one of the safest DeFi protocols due to its extensive security audits, transparent codebase, and long-standing operational history without major incidents.
Q: Can I lose money using Compound?
A: While the protocol itself is secure, users can face financial losses through market volatility or improper management of leverage. Borrowers may be liquidated if their collateral value drops significantly.
Q: How are interest rates determined on Compound?
A: Rates are set algorithmically based on real-time supply and demand. When demand to borrow an asset rises, so does its interest rate—benefiting lenders.
Q: Do I need to pay to use Compound?
A: There are no platform fees, but users pay standard blockchain gas fees when interacting with the protocol. These vary depending on network congestion.
Q: What happens if I get liquidated?
A: If your health factor falls below 1, your position becomes eligible for liquidation. A portion of your collateral can be sold at a discount to repay your debt and stabilize the system.
Q: Can I use Compound on mobile devices?
A: Yes—via compatible Web3 wallets like MetaMask or Trust Wallet integrated with decentralized applications (dApps).
Final Thoughts
Compound Finance continues to be a foundational pillar in the DeFi space—a robust, battle-tested platform that enables individuals to earn yield, access liquidity, and participate in governance without intermediaries.
Its combination of algorithmic markets, cToken-based rewards, multi-chain availability, and community-driven upgrades makes it a powerful tool for both novice and advanced crypto users.
Whether you're looking to generate passive income from idle assets or leverage your holdings for strategic trades, Compound offers a transparent and efficient solution rooted in decentralization.
