Introduction to Compound Finance
Compound Finance is a leading decentralized finance (DeFi) protocol that revolutionized crypto lending and borrowing. As an algorithmic money market protocol built on Ethereum, it enables users to:
- Earn interest on deposited cryptocurrencies
- Borrow assets against collateral
- Participate in decentralized governance via COMP tokens
With over $3.5 billion in total value locked (TVL), Compound remains one of the most established DeFi platforms in the cryptocurrency ecosystem.
How Compound Finance Works
The Core Mechanism
Compound operates through autonomous smart contracts that:
- Automatically match lenders and borrowers
- Calculate interest rates algorithmically based on supply/demand
- Manage collateralization and liquidation processes

Key Features
- Permissionless access: Anyone with a Web3 wallet can participate
- Transparent operations: All transactions are verifiable on-chain
- Algorithmic rates: Interest rates adjust in real-time
- Liquidity pools: Collective funds enable instant borrowing
The Lending Process Explained
Step-by-Step Guide
- Connect a Web3 wallet (e.g., MetaMask)
- Deposit supported assets (ETH, USDC, DAI, etc.)
- Receive cTokens representing your deposit
- Earn interest that compounds every Ethereum block (~15 seconds)
Supported Assets
| Asset | cToken | Typical APY |
|---|---|---|
| ETH | cETH | 0.5-3% |
| USDC | cUSDC | 1-5% |
| DAI | cDAI | 1-6% |
The Borrowing Process Demystified
How to Borrow
- Deposit collateral (minimum 50% collateralization)
- Select asset to borrow
- Receive funds instantly (no credit checks)
- Maintain collateral ratio to avoid liquidation
Collateral Factors
- ETH: 75%
- USDC: 80%
- WBTC: 70%
Understanding cTokens
What Are cTokens?
cTokens are interest-bearing tokens that:
- Represent your share in a liquidity pool
- Accrue interest continuously
- Can be redeemed for original assets plus interest
Example Flow
- Deposit 1 ETH → Receive cETH
- cETH balance grows over time
- Redeem cETH → Receive ETH + accumulated interest

Frequently Asked Questions
Is Compound Finance safe to use?
Compound has been audited multiple times and has operated securely since 2017. However, all DeFi protocols carry inherent smart contract risks.
What's the minimum amount to start lending?
There's no minimum - you can start with any amount of supported tokens.
How often is interest paid?
Interest compounds every Ethereum block (~15 seconds) and is reflected in your cToken balance.
Can I lose money providing liquidity?
The main risk is smart contract failure. Market risks are minimal as you're not exposed to price fluctuations of your deposited assets.
What happens if my loan gets liquidated?
If your collateral ratio falls below the required threshold, your position may be liquidated with a penalty fee.
How do I participate in governance?
Hold COMP tokens in a Web3 wallet and connect to Compound's governance portal to propose or vote on changes.
