Decentralized finance (DeFi) has reshaped how individuals interact with financial services, removing intermediaries and enabling peer-to-peer lending, borrowing, and yield generation. At the forefront of this revolution stands Compound Finance, one of the earliest and most influential DeFi protocols. Built on the Ethereum blockchain, Compound offers an autonomous money market where users can earn interest on their crypto assets or borrow against them—without relying on traditional banks.
With a total value locked (TVL) of approximately $3.5 billion at its peak and a governance token, COMP, that empowers community-driven development, Compound remains a pivotal player in the DeFi ecosystem.
Understanding Compound Finance
In traditional finance, compounding refers to the process of earning interest on both the initial principal and accumulated interest over time. In the world of decentralized finance, Compound Finance takes this concept further by enabling users to grow their crypto holdings automatically through algorithmically determined interest rates.
Launched in 2017 by Robert Leshner and Geoffrey Hayes, Compound is an open-source, blockchain-based protocol that functions as a self-sustaining money market. It allows users to lend and borrow cryptocurrencies using smart contracts—self-executing agreements coded directly onto the Ethereum network. This eliminates the need for centralized institutions, reduces operational friction, and opens financial services to anyone with an internet connection.
The platform supports major digital assets such as ETH, DAI, USDT, BAT, and others, each with its own liquidity pool. Interest rates are adjusted in real time based on supply and demand dynamics within these pools.

How Does Compound Finance Work?
At its core, Compound operates like a dynamic savings and loan system powered entirely by code.
When users deposit crypto into the platform, they become liquidity providers. Their funds are added to shared liquidity pools from which borrowers can draw loans. In return, lenders earn interest—paid in the same asset they deposited—calculated per block and distributed continuously.
Interest rates are not fixed. Instead, they are determined algorithmically:
- When demand for borrowing a specific asset increases, interest rates rise to incentivize more deposits.
- When supply exceeds demand, rates decrease to encourage borrowing.
Smart contracts handle all aspects of fund management, collateralization, interest accrual, and liquidations—ensuring transparency, security, and efficiency.
This automated mechanism allows Compound to operate 24/7 without downtime, approval delays, or credit checks.
The Lending Process on Compound
To begin earning yield on crypto assets, users must connect a Web3 wallet—such as MetaMask—to the Compound interface. Once connected, they can supply supported tokens to available markets.
Upon depositing funds:
- The protocol mints cTokens (e.g., depositing ETH generates cETH).
- These cTokens represent the user’s share of the liquidity pool and accrue interest over time.
- Users retain ownership of their underlying assets; cTokens act as receipts that can be redeemed later.
As interest accumulates, the exchange rate between cTokens and the underlying asset increases. For example, if you initially receive 100 cETH for 1 ETH, after several weeks your balance might still show 100 cETH—but it could now be redeemable for 1.03 ETH due to accrued yield.
Importantly, while funds are deposited, they cannot be freely transferred until withdrawn from the protocol.
The Borrowing Mechanism
Borrowing on Compound requires collateral. Users must lock up crypto assets worth more than the amount they wish to borrow—a concept known as over-collateralization.
Each supported asset has a collateral factor, typically ranging from 50% to 75%. For instance:
- If DAI has a collateral factor of 75%, $1,000 worth of DAI can back a loan of up to $750.
- Borrowers cannot exceed their borrowing limit without risking liquidation.
Liquidation occurs when a borrower’s health factor drops below 1.0—usually due to price volatility reducing the value of collateral. In such cases:
- Liquidators can repay part of the outstanding debt.
- In return, they receive a portion of the borrower’s collateral at a discounted rate (typically 5–8% below market value).
This incentive mechanism ensures the system remains solvent even during market downturns.

What Are cTokens?
cTokens are ERC-20 compatible tokens issued by Compound when users supply liquidity. They serve three primary functions:
- Represent ownership in a lending pool.
- Accrue interest in real time.
- Can be used in other DeFi protocols for further yield optimization (e.g., staking or providing liquidity elsewhere).
Because cTokens are tradable and composable, they enhance capital efficiency across DeFi. For example, cDAI can be used as collateral on another platform to take out additional loans—enabling advanced strategies like leveraged yield farming.
Despite representing real value, cTokens should not be confused with stablecoins or governance tokens; their value grows relative to the underlying asset over time.
The Role of COMP: Governance and Incentives
COMP is Compound’s native governance token with a maximum supply of 10 million. It plays a central role in decentralizing control over the protocol.
Key features of COMP:
- Enables holders to propose and vote on changes (e.g., adding new markets, adjusting risk parameters).
- Distributed automatically to users who supply or borrow assets.
- Requires 1% of total supply (100,000 COMP) to submit a governance proposal.
- Needs at least 400,000 votes for a proposal to pass.
Approximately 42% of COMP tokens are allocated to users via liquidity mining—distributed daily at a fixed rate across active markets. This dual reward model (50% to lenders, 50% to borrowers) encourages balanced participation.
Over time, Compound transitioned from centralized development by Compound Labs Inc. to full community governance—an evolution that strengthens trust and long-term sustainability.
Founders and Development Team
Compound was co-founded by:
- Robert Leshner (CEO), former product lead at Postmates and financial advisor.
- Geoffrey Hayes (CTO), experienced software engineer and tech executive.
Both University of Pennsylvania alumni, they previously launched Safe Shepherd, an identity protection startup. Today, they lead Compound Labs, the organization responsible for maintaining and advancing the protocol’s infrastructure—including Compound Treasury, a product designed to help traditional institutions access DeFi yields safely.
Their vision continues to shape innovation in decentralized finance.
COMP Price History and Market Performance
COMP launched via an informal distribution model in June 2020. Its price surged from around $65 to nearly $337 within days—an early sign of strong market interest.
Throughout 2021:
- Reached $534 amid broader crypto bull run.
- Peaked at $911.20 in May 2021 following the launch of Gateway (a cross-chain interest rate market) and Compound Treasury.
- Fell sharply in late 2021 and into 2022 as macroeconomic conditions worsened.
By mid-2022, COMP had declined to around $27.84 amid industry-wide sell-offs. Despite volatility, it maintains a top-tier ranking among DeFi tokens by market capitalization.
Is Compound Finance Safe?
While generally secure, Compound faced a critical incident in October 2021 when a faulty upgrade led to unintended COMP token emissions—exposing over $160 million in rewards. Though no user funds were lost, about $38.7 million was returned voluntarily after public appeals.
This event highlighted risks inherent in smart contract systems but also demonstrated the responsiveness of its community.
Competition from platforms like Aave and MakerDAO has intensified, yet Compound’s robust architecture, transparent governance, and consistent upgrades keep it relevant in a rapidly evolving space.
Frequently Asked Questions (FAQ)
Q: Can I lose money using Compound?
A: Yes. While your principal is protected from theft via smart contract design, impermanent loss isn't applicable here since you're not providing AMM liquidity. However, price volatility of collateralized assets may lead to liquidation if not monitored.
Q: How often is interest paid on Compound?
A: Interest accrues every Ethereum block (approximately every 12 seconds) and is compounded automatically—you don’t need to claim it manually.
Q: Do I need KYC to use Compound?
A: No. As a decentralized protocol, Compound does not require identity verification or account registration.
Q: What happens if I forget my wallet?
A: There is no recovery option. Access depends entirely on your private keys or seed phrase—lose them, and your funds are irretrievable.
Q: Are COMP rewards taxable?
A: In many jurisdictions, yes. Yield and token rewards are often treated as taxable income upon receipt.
