Compound Protocol - Lend & Borrow in DeFi 2025

Decentralized finance has transformed how we think about lending and borrowing, and Compound Protocol stands as one of the foundational pillars of this revolution. Since its launch in 2018, Compound has established itself as the gold standard for algorithmic, autonomous lending protocols, processing billions of dollars in transactions and serving as critical infrastructure for the broader DeFi ecosystem. This comprehensive guide explores everything you need to know about using Compound Protocol in 2025, from basic lending concepts to advanced yield farming strategies. Whether you're a DeFi newcomer looking to earn your first yield on crypto assets or an experienced user seeking to optimize your lending strategies, this guide provides the insights and practical knowledge needed to navigate Compound's sophisticated yet user-friendly platform effectively.

What Is Compound Protocol?

Compound is a pioneering decentralised finance (DeFi) protocol built on Ethereum that enables users to lend and borrow cryptocurrencies without intermediaries. Launched in 2018, Compound has become one of the most trusted and widely-used DeFi protocols, with over $3 billion in total value locked (TVL) at its peak.

The protocol operates through smart contracts that automatically match lenders and borrowers, setting interest rates based on the dynamics of supply and demand. When you deposit assets into Compound, you receive cTokens (like cUSDC or cETH) that represent your claim on the underlying assets plus accrued interest. These cTokens continuously appreciate in value, allowing you to earn interest simply by holding them.

What makes Compound unique is its algorithmic approach to interest rates and its role as a foundational building block for other decentralised finance (DeFi) protocols. Many other applications integrate with Compound to provide lending services, making it a critical piece of DeFi infrastructure in 2025.
