What Is Compound Protocol?

It is a pioneering decentralised finance (DeFi) protocol built on Ethereum that enables users to lend and borrow cryptocurrencies without intermediaries. Launched in 2018, it remains one of the most trusted lending markets in crypto, historically reaching over $3 billion in total value locked (TVL) at its peak (DeFiLlama).

As of 2025, Compound maintains:

• $800M–$1.2B TVL across all supported markets
• $400M+ supplied liquidity in USDC — its largest market
• $150M+ borrowed liquidity across major assets
• Major assets: USDC, ETH, WBTC, DAI
• Typical APYs: 1–4% supply APY, 2–6% borrow APY (varies by utilisation)
• Utilisation rate: 30–85% depending on asset
• Risk modelling: managed by Gauntlet & Chaos Labs (liquidation & collateral tuning)

The protocol operates through autonomous smart contracts that algorithmically adjust interest rates based on supply and demand dynamics. When you deposit assets into the protocol, you receive cTokens (such as cUSDC or cETH) that represent your claim to the underlying assets plus accrued interest. These cTokens continuously increase in value over time, allowing you to earn yield simply by holding them in your wallet without any manual intervention.

The protocol has strong governance. COMP token holders vote. They vote on protocol parameters. They vote on collateral factors. They vote on supported markets. They vote on system upgrades. Over 1000+ proposals executed. This happened since launch, when this DAO was one of the most active, and it remains very active in DeFi.

In 2025, it is deployed on Ethereum, which is the primary network, with selected expansions available. Layer 2 networks are used. This reduces gas costs, enabling users to save money. Many DeFi apps integrate it, using it as a backend, which is a lending layer, which is core infrastructure, which is for decentralised finance.

Technical Architecture

Interest Rate Models

The protocol has smart interest rate models that automatically adjust with changes in borrowing and lending rates, based on supply and demand. Each asset market is separate. The protocol uses utilisation curves. These incentivise optimal liquidity, thereby increasing borrowing costs. This happens as utilisation grows. These models ensure efficiency. Capital is allocated well. Liquidity reserves are maintained, with user withdrawals working. Market stability is preserved. This works during volatility.

Interest rate calculations use many variables: total supply, total borrowings, and reserve factors matter, while market parameters are specific. Governance can adjust these based on conditions and risk. Advanced users analyse parameters. They predict rate movements and optimise strategies. The protocol is transparent, with calculations performed on-chain. This enables yield farming. This enables portfolio management. Systems respond to conditions. They respond in real-time.

cToken System

The protocol has innovative cTokens. They are interest-bearing, representing supplied assets, with returns compounding automatically. No manual claiming needed; no manual reinvestment required. Each cToken represents a proportional claim. It includes the asset pool. It includes accumulated interest. Exchange rates increase continuously. Interest accrues over time. This design enables composability. Other DeFi protocols accept cTokens as collateral. They integrate them into strategies.

The cToken architecture features automatic interest compounding and rewards distributed proportionally. Redemption is seamless, with liquidity maintained. User access is preserved. Developers integrate cTokens, using smart contracts, market makers, and yield platforms. They create financial products. They leverage interest capabilities. This composability is important. It made the protocol foundational. Many DeFi innovations use it. Institutional products use it.

Risk Management

The protocol has risk management. Collateral factors are dynamic, with liquidation thresholds in place. Liquidation is automated, protecting the protocol, preventing insolvency. Borrowers are treated fairly. Risk parameters are monitored. They are adjusted continuously. Governance proposes changes based on volatility, correlation, and history. Liquidation algorithms are advanced. Debt recovery is efficient. Market impact is minimised, creating arbitrage opportunities, benefiting liquidators.

The liquidation system is sophisticated. Partial liquidation is possible, allowing borrowers to maintain positions and reducing exposure. Complete liquidation is avoided. Users monitor health factors and implement strategies. Risk management is automated. Collateral is added automatically. Debt is repaid automatically. This happens near thresholds. The protocol is transparent. Liquidation mechanics are clear. Protection services are developed. Risk tools are automated. Users maintain healthy positions. This works during volatility.

Institutional Use

Corporate Treasury

The protocol is preferred by corporations for treasury management, enabling businesses to earn yield. This is on idle cash, with liquidity maintained. Operational needs are met. Major corporations use it. DAOs use it too. Interest rate mechanisms are transparent. Treasury performance is optimised, preserving flexibility, while business operations continue, with algorithmic rates adjusting to provide competitive returns. Traditional banking is exceeded, with transparency provided and control maintained. Institutional users are satisfied.

Enterprise integration capabilities include API access for automated treasury management, bulk transaction processing for large deposits and withdrawals, and comprehensive reporting tools that meet institutional accounting standards. Advanced users can implement automated rebalancing strategies that optimise yield across different assets based on market conditions and corporate risk tolerance. The protocol's governance model allows institutional participants to influence protocol development and parameter adjustments that affect their treasury operations.

Regulatory Compliance and Institutional Security Standards

Compound's transparent on-chain operations provide institutional users with comprehensive audit trails and compliance documentation required for regulatory reporting and internal risk management. The protocol's open-source smart contracts enable independent security audits and formal verification processes that meet institutional security standards. Major accounting firms and compliance specialists have developed frameworks for incorporating Compound positions into traditional financial reporting and risk management systems.

Institutional security features include multi-signature wallet integration, hardware security module support, and integration with enterprise custody solutions that provide additional layers of protection for large-scale deployments. The protocol's governance model includes institutional participation mechanisms that allow large stakeholders to influence protocol development while maintaining decentralised decision-making processes. Regular security audits and bug bounty programs provide ongoing assurance about protocol security and reliability for institutional users.

Integration with Traditional Financial Infrastructure

Compound's growing integration with traditional financial infrastructure includes partnerships with major banks, asset managers, and fintech companies that provide institutional clients with seamless access to DeFi yield opportunities. These integrations enable traditional financial institutions to offer their clients exposure to Compound's interest-bearing assets while maintaining familiar user interfaces and compliance frameworks. The protocol's standardised interfaces and extensive documentation facilitate integration with existing portfolio management systems and risk monitoring tools.

Advanced integration capabilities include real-time position monitoring, automated risk management, and integration with traditional banking systems, enabling seamless fund transfers and position management. Institutional users benefit from dedicated support channels, priority transaction processing, and customised reporting tools that meet specific regulatory and operational requirements. The protocol's commitment to transparency and decentralisation ensures that institutional adoption enhances rather than compromises the platform's open and permissionless nature.
