At a glance
Aave ↗ and Compound ↗ defined on-chain lending, launching in 2017 and 2018. As of May 2026, Aave commands $22B in TVL across 9 chains, while Compound holds $2B across 5. This comparison breaks down the metrics that matter for depositors and borrowers. Aave offers deeper liquidity and the GHO stablecoin; Compound provides a simpler Comet model for risk-conscious users.
Key differences
TVL and liquidity: Aave's $22B dwarfs Compound's $2B, an 11x difference. This translates to lower slippage and higher borrowing capacity on Aave. Chain coverage: Aave spans Ethereum, Arbitrum, Polygon, Avalanche, Optimism, Base, Metis, BNB, Gnosis — 9 networks total. Compound operates on Ethereum, Arbitrum, Polygon, Base, and Optimism — 5 chains. Mechanism design: Aave V3 uses pooled multi-asset markets with isolation and eMode, plus an upcoming V4 hub. Compound V3 (Comet) structures each market around a single borrow asset with multiple collaterals, simplifying risk and allowing efficient liquidations. Native stablecoin: Aave issues GHO, an overcollateralized stablecoin with $260M+ circulation, generating protocol revenue. Compound has no equivalent asset.
Security and track record
Both protocols have passed multiple audits by top-tier firms: Aave with Trail of Bits, OpenZeppelin, Certora; Compound with the same three. Neither has suffered a major exploit according to our incident data. With launch dates in 2017 and 2018, they are among the most battle-tested DeFi protocols. Aave's more complex architecture (V3, V4, GHO) introduces potential attack surface, but its audit cadence and bug bounty programs mitigate this. Compound's simpler Comet markets reduce smart-contract risk for users who prefer a minimal footprint.
Fees and costs
Both protocols charge a reserve factor on borrow interest — a percentage of the interest paid by borrowers that goes to the protocol treasury. Exact rates vary by market, asset, and utilization. Our data does not provide current fee schedules; users should compare rates directly on each protocol's analytics dashboard. In general, Aave's larger liquidity often results in slightly better rates for major assets, but this is not guaranteed.
Which should you choose
Pick Aave if you need the deepest liquidity across the most chains, want to mint or earn yield on GHO, or if you're comfortable with a feature-rich platform. Pick Compound if you prefer single-asset borrow markets that isolate risk, value protocol simplicity, or are active on chains where Compound offers competitive rates. Both are secure, time-tested options; the choice hinges on your risk appetite and specific use case.
Verdict
Aave wins on nearly every quantitative metric — TVL, chains, feature set, and stablecoin integration. Compound remains a respected pioneer, but for most users in 2026, Aave is the superior choice. However, if you prioritize a minimalist lending experience, Compound's Comet markets are worth a look.
