What Is Compound and What Does It Do?

Compound is a decentralized finance (DeFi) lending protocol that runs on the Ethereum blockchain. Compound allows users to generate interest on their crypto deposits and borrow crypto assets using algorithmically-determined interest rates. Compound was developed by Robert Leshner and Geoffrey Hayes, and it uses smart contracts that automate lending and borrowing processes without the use of intermediaries.

What Are the Best Use Cases for Compound?

Cryptocurrency Holders
Compound allows investors to earn interest on their idle cryptocurrency assets while still maintaining control of those assets. Investors do not have to sell their cryptocurrency assets in order to access this interest. Additionally, the interest rate that is earned on these assets adjusts dynamically as market conditions change.
Crypto Leverage Traders
Compound allows traders to leverage their trading positions through borrowing using collateralized cryptocurrency. This allows traders to increase their exposure to a particular asset without having to liquidate their long-term holdings.
DeFi Developers
Compound is an open protocol and allows developers to create decentralized financial (DeFi) applications utilizing Compound’s liquidity pools.
Institutional Crypto Investors
Compound allows users to access regulated lending and borrowing through a decentralized governance structure and clear on-chain mechanics.
NOT FORTraditional Finance Operations
Compound does not offer the same level of regulatory compliance as traditional institutions, specifically SEC registration and FDIC insurance. It also does not provide the ability for centralized account management like traditional financial institutions.
NOT FORNon-Technical Users Unfamiliar with Crypto
Compound is not designed for institutional clients due to the requirement of knowledge and experience related to managing smart contracts, gas fees, collateralization ratios, and crypto wallet management.
NOT FORRisk-Averse Savers
Compound poses risks to users in terms of smart contract failures, volatility in the crypto markets, and the possibility of being liquidated if the value of collateral decreases below a predetermined threshold.

How Does Compound Compare to Competitors?

vs Aave

Compound was one of the first protocols to develop an algorithmic money market model however Aave now has more features and has surpassed Compound in total value locked (TVL). While Compound has remained focused on developing a reliable lending platform, Aave has been expanding its offerings to include more than just lending.

Compound offers simple and battle-tested lending options; Aave offers lending and borrowing options tailored toward the advanced DeFi user.

vs MakerDAO

Compound is able to offer dynamic interest rates for a wide range of currencies while Maker’s DAI stablecoin system is limited to offering stable interest rates for a single currency. Maker has a larger market presence, however Compound is able to provide a wider array of use cases that do not require a reliance on a single stable currency.

Compound offers diversified lending/borrowing options; Maker offers stablecoin exposure.

vs Morpho

Compound's loan-to-value (LTV) ratio is optimized by Morpho through peer-to-peer (P2P) matching. Compound retains greater liquidity and is a well-established name within the cryptocurrency space while Morpho delivers superior yields but at the cost of additional complexity through smart contracts.

Compound offers maximum liquidity; Morpho offers yield optimization.

vs Yearn Finance

Yearn facilitates auto-compounding yields across various protocols, including Compound. The Compound protocol serves as the underlying market, while Yearn adds an additional layer of complexity and may deliver superior returns for the passive investor.

Compound allows direct market access; Yearn facilitates automated yield farming.

What Are Common Questions About Compound?

Compound is a smart contract protocol for generating interest through providing assets for users to earn interest and/or borrow against their collateral. Interest rates will fluctuate based upon demand/supply in each market; governance over the Compound protocol is governed through the COMP token which can be used to control protocol parameters.

Compound can be accessed through four blockchain networks including ethereum mainnet, Arbitrum, Base, and Polygon; users simply need to link their web3 wallets to interact with markets on the Compound network.

Compound uses a single variable/stable rate model per market; however, Compound does offer algorithmic adjustments to these rates. Aave also offers more rate modes and flash loans than Compound; both are battle tested lending protocols.

Funds deposited into Compound are secured by smart contracts that have been audited and have proven themselves to be secure over time. Due to the fact that Compound is a decentralized platform, users maintain possession of their private keys and do not require central custody. In addition to the auditing of the smart contracts, Compound has implemented multiple other methods to improve the security of its protocol including bug bounties and multiple audits.

Yes, via smart contracts and Compound.js SDK. Also compatible with wallets, dApps, and DeFi aggregators; developers build atop Compound using the same EVM tooling they would when working with other DeFi projects.

Join Compound's discord server to participate in weekly developer calls and to receive assistance from the community. Check out compound.finance/docs and the #resources channel on discord for information regarding Compound's resources. GitHub is available for reporting Compound.js SDK issues.

Compound does not require sign-up; users may link their wallet to begin interacting with Compound's markets immediately and access permissionless lending and borrowing functionality.

Users of Compound are subject to the same risks associated with smart contracts and are subject to the risk of liquidation should the value of the collateral drop below the amount borrowed. Although Compound provides a robust and user-friendly experience, it does provide limited customer support and is instead dependent on a community driven model. In addition to the costs associated with smart contract usage, Compound also incurs gas fees associated with interacting with the underlying blockchain network.

Is Compound Worth It?

Compound is the pioneering protocol that introduced the concept of algorithmically generated interest rates and was the first to introduce lending and borrowing functionality to DeFi applications. Although new competitors have developed additional features to those provided by Compound, its simplicity, long standing reputation for being auditable and secure, and large developer base makes it a fundamental part of the DeFi application stack.

What Lending Features Does Compound Offer?

Collateral-Based Lending

Before users may borrow they are required to provide assets to the protocol as collateral. Reputation and credit history do not have any influence on borrowing eligibility. Only the asset’s value and quality will determine if a user is eligible to borrow.

Algorithmic Interest Rates

The interest rates are set by algorithms, based on the supply/demand principle of lending, and adjust every time a new block is mined.

cToken System

Users who lend through this protocol receive cTokens (cEther, cDAI, etc.), which represent their ownership in the lending pool, and earn interest on them automatically.

Liquidation Mechanism

In the event that a borrower’s collateral becomes worth less than what it was when the loan was created, liquidators can take back some of a borrower’s outstanding balance at a discounted price and be rewarded with some of the collateral as well.

Risk Management Reserves

This protocol uses the reserve funds that come from all of the interest payments to help protect against default, bugs, and oracle failures.

Compound III Single Asset Model

Because this protocol is streamlined and only allows one major asset (USDC) to be borrowed against, it reduces the amount of systemic risk and makes managing that risk easier.

Supply Caps

The governance system for this protocol controls the upper limit of how much of an asset can be supplied into the lending pool to control the collateral risk.

Optimized Liquidations

By improving the liquidation process, this protocol also improves fairness so that borrowers are protected from having their assets unfairly liquidated due to temporary volatility in the marketplace.

Lower Gas Costs

Gas costs for Compound III are significantly lower than those of other DeFi lending services.

How Does Compound Assess and Mitigate Risk?

Liquidation RiskVolatile collateral can drop in value; positions auto-liquidate when approaching borrowed amount value. Borrowers lose collateral but keep borrowed assets
Overcollateralization RequirementAll loans must be overcollateralized. Protocol maintains reserves and collateral factors to ensure supplied assets exceed borrowed assets
Credit MechanismNo credit checks required; any user with qualifying collateral can borrow. Protocol secured by asset value and liquidation mechanisms rather than reputation
Asset Quality RiskProtocol assigns collateral factors based on asset quality and stability. Higher quality assets allow greater borrowing power
DecentralizationRemoves traditional intermediaries enabling peer-to-peer lending without banks or credit institutions
