Aave is roughly ten times Compound's size in 2026. This comparison looks at what that gap actually means for a supplier: rates, architecture, and the case that still exists for the smaller protocol.
Key Takeaways
- Aave holds $12.2B in TVL against Compound's $1.1B as of June 10, 2026 per DeFiLlama. Five years ago they were peers.
- Supply rates are closer than the size gap suggests: 3 to 6% on USDC at Aave against 3 to 5% at Compound. You are not paid much extra for Aave's dominance.
- The real difference is architecture. Aave's monolithic pool maximizes capital flexibility. Compound V3's isolated markets contain failure per pool. Treasuries weigh that differently than yield farmers do.
Background
Compound effectively invented pooled DeFi lending and triggered the 2020 DeFi summer with COMP incentives. Aave out-shipped it from there: more chains, more collateral types, E-mode, GHO, and an aggressive multi-chain deployment that Compound never matched. The TVL divergence followed the shipping cadence.
Compound's answer was V3, called Comet: a deliberate simplification. Each market has one borrowable base asset, with collateral siloed per market. Less flexible, fewer failure modes.
Analysis
Aave V3
$12.2B across 15+ EVM chains. The widest collateral menu in lending, cross-chain portals, and liquidation infrastructure that has cleared every major stress event since launch. The monolithic pool design means all assets share one liquidity contract, so a failure in one listed asset can, in principle, propagate. Aave manages that with conservative parameters and the Safety Module, and so far the record holds.
Compound V3
$1.1B in TVL, concentrated in USDC markets on Ethereum and Base. One base asset per market means a collateral failure is contained by construction rather than by parameter tuning. Gas costs are lower, the audit surface is smaller, and the protocol has maintained its safety record through every major DeFi stress event. For an allocator running treasury capital where the mandate is return of capital first, that containment is the product.
Data
| Metric | Aave V3 | Compound V3 |
|---|---|---|
| TVL | $12.2B | $1.1B |
| USDC supply APY (typical range) | 3 to 6% | 3 to 5% |
| Architecture | Monolithic pool | Isolated markets (Comet) |
| Chains | 15+ | Ethereum, Base, Arbitrum, Polygon |
| Collateral breadth | Widest in DeFi | Narrow by design |

Implications
The 100 to 150bps you give up at Compound is the price of structural containment. Whether that price is worth paying depends on the size and mandate of the capital, not on the protocol. Most active allocators end up in Aave for depth and rate. Treasury-style capital keeps showing up in Compound for reasons that have nothing to do with headline APY.
The mistake is choosing once and forgetting. Rates, utilization, and incentive programs move weekly, and the right venue for a position this month is not guaranteed to be the right venue next month. The protocols will not tell you that. A position-level view across both will.
Risk Considerations: DeFi lending carries smart contract risk, liquidation risk during volatility, and oracle dependency. Isolated markets contain failures but concentrate liquidity. Maintain conservative loan-to-value ratios.
