Compound stands as a foundational protocol within the decentralized finance (DeFi) ecosystem. It operates as an algorithmic, autonomous interest rate protocol built on the Ethereum blockchain, enabling users to lend and borrow a variety of cryptocurrencies without the need for a traditional financial intermediary. By leveraging smart contracts, Compound creates open and accessible money markets for the digital age.
What is the Compound (COMP) Protocol?
Compound is a decentralized finance (DeFi) protocol that functions as an algorithmic money market. Its core mission is to transform traditional financial systems into transparent, decentralized versions that are open to everyone. This allows everyday users to access financial services and earn yields that were once predominantly available to large institutions.
At its heart, the protocol facilitates peer-to-peer lending and borrowing through pooled liquidity. Users who supply their digital assets to these pools earn interest, while borrowers can take out loans by providing sufficient collateral. All of this is managed automatically by audited smart contracts, ensuring the system remains secure and trustless.
Key Advantages of Using Compound
Compound offers a compelling set of benefits that have made it a cornerstone of the DeFi landscape.
Open Access and Permissionless Lending
There are no gatekeepers or credit checks on the Compound platform. Anyone with an internet connection and a compatible cryptocurrency wallet can participate. Loans are disbursed instantly upon the provision of adequate collateral, democratizing access to financial tools.
Passive Income Generation
Users can put their idle crypto assets to work. Instead of simply holding cryptocurrencies and hoping their value appreciates, you can lend them out to earn a passive, compounding interest income, all while retaining ownership of your underlying assets.
Support for Bitcoin in DeFi
A significant innovation was the integration of Wrapped Bitcoin (WBTC), an ERC-20 token representing Bitcoin on the Ethereum blockchain. This allows Bitcoin holders to use their BTC as collateral to borrow assets or participate in lending within the Compound ecosystem, bridging two major crypto ecosystems.
Autonomous and Secure Operation
The protocol runs entirely through smart contracts that have undergone rigorous audits by top-tier security firms like Open Zeppelin and Trail of Bits. This ensures that all operations—from storing funds to calculating interest—are executed automatically and securely without human intervention.
High Degree of Interoperability
Staying true to the ethos of DeFi, Compound is designed to be composable. It supports integration with a wide array of third-party applications, wallets, and DeFi services. This interoperability allows developers to build new financial products on top of Compound's reliable base layer.
How Does Compound (COMP) Work?
Understanding the mechanics behind Compound is key to utilizing it effectively. The protocol's design is elegant in its simplicity for the end-user, though it is powered by complex smart contracts.
The Core Concept: Yield Farming
The process of supplying assets to earn interest is commonly known as yield farming or liquidity mining. When you supply assets to a Compound pool, you begin earning interest immediately, calculated and distributed with every new Ethereum block.
Understanding cTokens
When you deposit an asset like USDC or ETH into Compound, you receive a derivative token called a cToken (e.g., cUSDC or cETH) in return. These cTokens are ERC-20 tokens that represent your share in the liquidity pool and continuously accrue interest. You can transfer, trade, or use these cTokens elsewhere in the DeFi ecosystem. When you redeem your cTokens, you receive your original principal plus the accrued interest.
Borrowing Assets
To borrow assets, a user must first supply collateral. The amount you can borrow is determined by a collateral factor specific to each asset. If the value of your supplied collateral falls too close to the value of your loan, your position can be liquidated to repay the lenders, a process managed automatically by the protocol.
Determining Interest Rates
Interest rates on Compound are not set by a central entity. Instead, they are algorithmically determined based on the real-time supply and demand for each asset within its respective market. When demand to borrow a specific cryptocurrency is high, its interest rate rises to incentivize more suppliers to provide liquidity.
Decentralized Governance with COMP Token
The COMP token is the governance token of the Compound protocol. Holding COMP grants you the right to create and vote on proposals that dictate the future of the protocol, such as adding new supported assets, changing collateral factors, or adjusting interest rate models. This ensures that the protocol remains decentralized and community-owned.
A Brief History of Compound
Compound was founded in 2018 by Robert Leshner, an economist with a deep understanding of both traditional and decentralized finance. The project quickly gained significant traction and funding:
- 2018: Secured $8.2 million in a seed funding round.
- 2019: Raised an additional $25 million in a Series A round led by renowned venture firm Andreessen Horowitz, with participation from Coinbase.
The protocol's launch of its COMP governance token and yield farming mechanism in the summer of 2020 is widely credited with igniting the "DeFi Summer" boom, cementing its place as a pioneer in the space.
How to Use the Compound Protocol
Getting started with Compound is a straightforward process that requires no lengthy sign-ups or personal information.
- Get a Web3 Wallet: You will need a non-custodial Web3 wallet like MetaMask, Coinbase Wallet, or WalletConnect to interact with the Ethereum-based application.
- Fund Your Wallet: Ensure your wallet holds some Ethereum (ETH) to pay for transaction fees (gas) and any assets you wish to supply.
- Connect to the App: Visit the Compound application and connect your Web3 wallet.
- Supply Assets: Navigate to the market you want to supply to, click "Supply," and confirm the transaction. You will receive your cTokens automatically.
- Borrow or Earn: Once you have supplied collateral, you can choose to borrow other assets or simply hold your cTokens to earn interest on your supplied assets.

Frequently Asked Questions About Compound
What is the main use of the COMP token?
The COMP token is primarily used for governance. It allows holders to propose and vote on changes to the Compound protocol, making its development and evolution a community-driven process.
Is it safe to lend my crypto on Compound?
While Compound's smart contracts are extensively audited and considered among the most secure in DeFi, risks remain. These include smart contract risk (potential for undiscovered bugs), liquidation risk if you are borrowing, and the volatility of the underlying crypto assets.
What is the difference between supplying and borrowing?
Supplying means depositing your crypto assets into a pool to earn interest. Borrowing means taking a loan from a pool against your supplied collateral, for which you must pay interest.
Can I lose money by supplying assets to Compound?
The act of supplying assets is generally low risk as you are not taking a leveraged position. The primary risk is the potential depreciation of the asset you are supplying. However, you are earning interest, which can help offset some of that volatility.
How are interest rates calculated?
Interest rates are determined algorithmically by each asset's market. The borrow rate is based on the utilization rate (how much of the supplied assets are being borrowed). The supply rate is then derived from the borrow rate, minus a small reserve factor set by governance.
What happens if my borrowed position gets liquidated?
If the value of your collateral falls below a certain health threshold, your position can be liquidated. This means a portion of your collateral is sold off to repay your borrowed amount, ensuring the protocol remains solvent. A liquidation penalty is also applied.
How to Securely Store COMP Tokens
For long-term holders or those making significant investments, a hardware wallet is the gold standard for security. Hardware wallets store your private keys offline, making them immune to online hacking attempts. Popular models from Ledger and Trezor fully support the storage of COMP and other ERC-20 tokens, keeping your assets safe in "cold storage."
