At its core, Compound enables users to deposit supported cryptocurrencies into liquidity pools, and in return receive cTokens—interest‑bearing tokens that represent their share of the pool. These cTokens grow in value over time, reflecting the earned interest. Borrowers, on the other hand, can take out loans by locking up collateral in the form of other crypto assets.
One of Compound’s key features is its algorithmic interest rate model. Interest rates are automatically adjusted based on supply and demand: when more people borrow a specific asset, the rate goes up to incentivize more lending, and vice versa. This dynamic pricing ensures efficient capital allocation without manual intervention.
Security and risk management are built into the system: loans must be over-collateralized, and if a borrower’s collateral drops in value beyond a certain threshold, their position can be liquidated to protect the protocol. Price feeds for assets are maintained via oracles to ensure accurate valuations.
Governance of the protocol is decentralized through the COMP token. COMP holders can submit and vote on proposals to upgrade the system, add new assets, or adjust key parameters. This gives the community real power in how the protocol evolves.
Founded by Robert Leshner and Geoffrey Hayes, Compound has become a cornerstone of the DeFi ecosystem. Its open, automated, and permissionless design enables users to earn yield on their crypto holdings or access liquidity without relying on banks—truly reimagining how money markets can work in a decentralized world.
