Compound Finance is a leading algorithmic money market protocol built on the Ethereum blockchain, designed to simplify decentralized borrowing and lending. By contributing assets to its liquidity pools, users can start earning interest immediately or borrow against their crypto holdings without intermediaries. This guide walks you through the core features, benefits, and step-by-step instructions for using Compound.
What Is Compound Finance?
Compound Finance is a decentralized lending protocol that enables users to deposit cryptocurrencies, borrow assets, and earn interest through automated smart contracts. It eliminates traditional financial intermediaries by using blockchain technology to create open, permissionless, and secure DeFi services.
As a non-custodial system, Compound allows anyone with an internet connection and a compatible Web3 wallet to participate. Interest rates for both borrowing and lending are adjusted algorithmically based on real-time supply and demand within each asset pool.
How Compound Works: Lenders and Borrowers
The protocol connects two primary user groups through smart contracts:
- Lenders deposit supported cryptocurrencies to earn annual percentage yield (APY), paid in both the original asset and COMP tokens. This turns idle assets into productive sources of passive income.
- Borrowers provide crypto collateral to borrow other assets. They maintain exposure to their original assets while accessing additional liquidity. Borrowers also offset interest costs through yield earned on supplied collateral.
Interest rates are determined automatically by the protocol, and all transactions are executed trustlessly without requiring negotiation or traditional credit checks.
The COMP Token: Governance and Rewards
COMP is the native ERC-20 governance and rewards token of the Compound ecosystem. It serves two primary functions:
- Rewards Distribution: Lenders and borrowers earn COMP tokens based on their activity and market participation. Distribution is proportional to the interest accrued in each market.
- Protocol Governance: COMP holders can propose and vote on changes to the protocol, such as adjusting interest rate models or adding new assets. Voting power is proportional to the number of tokens held.
COMP has a fixed supply of 10 million tokens, with nearly half allocated to users through ongoing participation rewards.
Supported Assets and Interest Rates
Compound supports several major cryptocurrencies for supplying and borrowing. Interest rates vary by asset and fluctuate based on utilization rates. Below are examples of assets currently available:
- Ether (ETH)
- Dai (DAI)
- USD Coin (USDC)
- Tether (USDT)
- Wrapped Bitcoin (WBTC)
- Basic Attention Token (BAT)
- Uniswap (UNI)
- Ox Token (ZRX)
Rates are updated in real time on the protocol’s official dashboard.
Advantages and Limitations of Compound
Benefits
- Higher interest returns compared to traditional savings accounts
- No know-your-customer (KYC) requirements or credit checks
- Permissionless access for global users
- Transparent and automated operations via smart contracts
- Interoperability with major Ethereum wallets and applications
Risks and Challenges
- Market volatility may lead to collateral liquidation
- Smart contract vulnerabilities or coding errors
- Competition from other DeFi lending platforms
- Limited selection of supported assets compared to centralized alternatives
- Gas fees on Ethereum can reduce profitability for small transactions
How to Get a Crypto Loan on Compound
Obtaining a loan on Compound is straightforward and does not require approval from a central authority. Users simply supply collateral and borrow against it. The process is self-repaying in the sense that interest earned on supplied assets can partially offset borrowing costs.
Requirements:
- Supported cryptocurrency to use as collateral
- Web3 wallet such as MetaMask or Ledger
- Ether (ETH) to cover transaction gas fees
Step-by-Step Borrowing Guide
- Connect Your Wallet: Visit the Compound application and connect a supported Web3 wallet.
- Supply Collateral: Choose an asset to deposit, enter the amount, and confirm the transaction. You must also enable the asset as collateral.
- Borrow Assets: Select a token to borrow, enter the desired amount, and approve the transaction. The borrowed funds will appear in your wallet.
- Monitor Your Position: Keep track of your borrow limit and collateral ratio to avoid liquidation.

How to Lend and Earn Interest on Compound
Lending on Compound involves supplying assets to a liquidity pool to earn interest. Your supplied balance automatically accrues APY, distributed in the underlying asset and COMP tokens.
Step-by-Step Lending Guide
- Access the Platform: Connect your wallet to the Compound app.
- Select an Asset to Supply: Review the supply APY and COMP distribution rates.
- Confirm Supply Transaction: Enter the amount and approve the transaction. Your assets will begin earning yield immediately.
- Track Earnings: Monitor your accumulated interest and COMP rewards through the dashboard.
Repaying Loans and Withdrawing Collateral
To repay a loan:
- Navigate to the "Borrow" section and select "Repay"
- Approve the transaction to reduce your borrowed balance
Once the loan is fully repaid, you can withdraw your collateral:
- Go to the "Supply" section and select "Withdraw"
- Confirm the transaction to return assets to your wallet
Understanding Liquidation Risks
Liquidation occurs when the value of a user’s borrowed assets exceeds their collateral value—often due to market volatility. Compound uses over-collateralization to mitigate this risk, but users must monitor their borrow limit closely.
If your account is liquidated, a portion of your collateral may be sold at a discount to repay the loan. To avoid liquidation, maintain a healthy collateral ratio and avoid borrowing near your maximum limit.
Participating in Compound Governance
COMP token holders can participate in protocol governance by voting on proposals or delegating voting power to others. Proposals may include changes to interest rate models, new asset listings, or technical upgrades.
To vote, connect your wallet to the governance portal and follow the instructions to cast your ballot manually or through a delegate.
Frequently Asked Questions
What is the minimum amount needed to use Compound?
There is no minimum deposit required to use Compound. However, since all transactions occur on the Ethereum network, you must have enough ETH to cover gas fees.
Can I lose money on Compound?
Yes. While supplying assets can generate yield, borrowers risk liquidation if collateral value declines sharply. Additionally, fluctuations in interest rates or token values may affect overall returns.
Is Compound Finance fully decentralized?
Compound is governed by COMP token holders, who vote on protocol upgrades and changes. However, some aspects of the system—such as initial admin keys—have drawn debate over its decentralization status.
How often are interest payments distributed?
Interest accrues continuously on supplied assets and is compounded every Ethereum block (approximately every 15 seconds). You can withdraw earned interest at any time.
What wallets are compatible with Compound?
Supported wallets include MetaMask, Ledger, Coinbase Wallet, and other Web3-enabled Ethereum wallets.
Are there alternatives to Compound?
Yes, other DeFi lending platforms like Aave, MakerDAO, and Venus offer similar services, often with different asset selections or rate structures.
Final Thoughts
Compound Finance plays a significant role in the decentralized finance ecosystem by offering accessible, efficient, and transparent lending and borrowing services. Its algorithmically driven interest rates and COMP reward system create compelling opportunities for crypto asset holders.
That said, users must remain aware of market risks, liquidation conditions, and network fees. Always conduct thorough research and consider your risk tolerance before participating in DeFi protocols.
