What Is Compound?

Compound is a decentralized money market that lets users supply assets and borrow against collateral. It is one of the oldest names in DeFi lending, but the product surface in 2026 is split between legacy v2-style markets and the newer Compound III design.

Compound’s official presence is accessible via Compound Finance, while the clearest mechanics explanation for modern markets sits in the Compound III documentation.

The most important thing to understand before any review details is the “base asset” model in Compound III. It changes what earns interest and how risk concentrates.

How Compound III Works

Compound III is an EVM-compatible protocol where users supply assets as collateral to borrow the base asset, and users can earn interest by supplying the base asset.

This is a single-borrow-asset model. Each market has one base asset that can be borrowed. Other supported assets can be supplied as collateral, but those collateral assets do not earn interest. The docs state this clearly: supplying collateral does not earn interest, while supplying the base asset earns interest when the account’s base balance is positive.

In practical terms, Compound III simplifies the market structure. It reduces cross-asset rate complexity, but it concentrates borrow demand into one base asset per market.

What Users Actually Do on Compound

Compound supports two primary user intents.

The first intent is earning yield by supplying the base asset. In a USDC base market, supplying USDC earns interest driven by borrower demand and utilization.

The second intent is borrowing the base asset using collateral. A user supplies assets like ETH or other supported collateral, then borrows the base asset against it.

In 2026, many users also route through aggregators and vaults, but the core mechanics and risks still come from the underlying Compound market.

The Interest Rate Mechanism

Compound rates are variable. They adjust with utilization, meaning the ratio of borrowed liquidity to supplied liquidity influences the borrow rate and the supply rate.

This variability is healthy in the sense that it is market-driven, but it makes headline rates a snapshot rather than a promise. A supply rate can drop quickly if borrow demand falls or if new supply enters.

For evaluation, the key is to track realized yield over time rather than rely on a single day’s rate.

Liquidations and the “Absorption” Model

Liquidation mechanics are where DeFi lending becomes real. Users borrow against collateral, and if the collateral value falls too far, positions can be liquidated.

Compound III uses an absorption mechanism where the protocol’s reserves can absorb undercollateralized accounts by paying base asset reserves in exchange for their collateral. Each absorption is paid for by protocol reserves, and then liquidators can buy absorbed collateral at a discount using the base asset to replenish reserves when reserves are below a governance-set target.

Mechanically, this design aims to keep markets solvent through reserves and discount sales, but it introduces a clear dependency: reserves health, oracle behavior, and liquidation efficiency all matter during sharp moves.

Governance and the COMP Token

Compound governance is controlled through COMP holders and delegates. The Compound III governance section describes governance as allowing the community to propose, vote, and implement changes through administrative smart contract functions, governed by holders and delegates of COMP.

This creates a familiar DeFi trade-off. Governance can evolve the system, but it can also change parameters in ways that impact markets. Risk settings, collateral factors, and reserve targets are not static.

A strong Compound evaluation includes governance awareness, not only APY monitoring.

What Compound Gets Right

Compound’s strongest feature is clarity. The protocol does one core job: it matches suppliers and borrowers through algorithmic interest rates.

Compound III improves clarity further by simplifying to a base-asset borrowing model. That reduces “which asset earns what” confusion and can make risk accounting easier.

Another strength is composability. Compound markets integrate widely across DeFi, which often improves liquidity and makes exit paths easier under normal conditions.

Where the Risks Live

Compound’s risk profile comes from a few predictable buckets.

Smart contract risk exists in any DeFi protocol. Even mature systems can fail.

Oracle risk matters because collateral pricing drives borrow limits and liquidation triggers.

Liquidity and utilization risk matters because rates are driven by utilization. A market can become expensive to borrow from during stress, and a market can become unattractive to supply when rates compress.

Liquidation risk is the major user risk. Borrowers face liquidation when collateral falls or when volatility spikes quickly. A “safe” health factor today can become unsafe during cascading liquidation events.

Governance risk exists because parameter changes can alter collateral support, interest rate models, or reserve policy.

Compound vs Other Money Markets in 2026

The 2026 lending landscape includes several strong competitors, many of which support multi-asset borrowing, isolated pools, or specialized collateral types.

Compound’s differentiator is the simplicity and predictability of its market mechanics. Compound III markets provide a more constrained set of behaviors, which can reduce certain classes of complexity.

The trade-off is concentration. A base-asset market ties borrowing and lending outcomes to one asset’s demand and liquidity. That can be a feature if the base asset is highly liquid. It can be a limitation if the base asset experiences fragmentation.

Who Compound Is Best For in 2026

Compound fits best for users who want straightforward supply-and-borrow mechanics without relying on complex strategy vaults.

It also fits borrowers who want to borrow a single base asset against collateral in a market with clear parameters.

It is less suitable for users who want interest on every collateral asset they hold, because collateral assets in Compound III do not earn interest by design.

A Safer Way to Use Compound

A conservative supply approach treats supply yield as variable and avoids assuming today’s APY persists.

A conservative borrow approach maintains a wide liquidation buffer. It also stress-tests collateral drops and rate spikes.

For large positions, the safer habit is to start small, confirm the market base asset, understand the collateral list, and monitor health factor behavior during volatility.

Compound is a tool. The main risk is not the tool existing. The main risk is users forcing leverage into narrow liquidation buffers.

Conclusion

Compound remains a core DeFi money market, and Compound III’s base-asset design is the defining feature in 2026. Supplying the base asset earns interest, collateral assets do not, and the market’s behavior is driven by utilization and liquidation efficiency.

Compound can be a strong choice for users who value clarity and composability, but its risks are the standard DeFi lending risks: smart contracts, oracles, liquidation cascades, and governance-driven parameter shifts. The safest outcomes come from treating rates as variable, maintaining conservative buffers, and sizing positions for volatility.
