Aave vs Compound: 2026 Comparison

Aave and Compound are the two original DeFi money-market protocols. Both let users deposit ERC-20 assets to earn interest and borrow against collateral non-custodially. Aave (V3 since 2022; multi-chain; portals, eMode, isolation mode, GHO stablecoin) is the larger and feature-richer of the two. Compound (V3 "Comet" since 2022) deliberately simplified to a single-borrowable-asset-per-market design (USDC, ETH, USDT markets), trading flexibility for safety and gas efficiency.

Side-by-side comparison

Feature	Aave	Compound
Launched	2017 (ETHLend → Aave V1 2020 → V3 2022)	2018 (V1 → V2 2019 → V3 "Comet" 2022)
Latest version (2026)	Aave V3 (+ V4 in development)	Compound V3 ("Comet")
Architecture	Multi-asset pool per market — borrow any listed asset	Single-borrowable-asset per market (USDC, ETH, USDT, etc.)
eMode (correlated assets)	Yes — higher LTV for correlated baskets (stables, ETH-LST)	No equivalent (V3 markets are inherently correlated)
Isolation mode	Yes — risky assets restricted to isolated borrow caps	Implicit via single-borrowable architecture
Cross-chain portals	Yes — Aave portals + GHO bridging	No (each chain market is independent)
Native stablecoin	GHO (decentralized, over-collateralized)	No
TVL (2026-05, approx.)	$12-15B across all chains	$2-3B
Chains deployed	Ethereum + 11 chains	Ethereum + 4 chains (Base, Arbitrum, Polygon, Mantle)
Token	AAVE (governance + safety module staking)	COMP (governance only)
Safety module / backstop	Yes — staked AAVE absorbs shortfall events	No on-protocol backstop
Best for	Power users wanting eMode/isolation/multi-borrow flexibility	Conservative lenders/borrowers who want a smaller blast radius

Where Aave wins

4-5× the TVL of Compound — deeper liquidity means lower utilization-driven rate spikes and tighter borrow rates for size.
eMode unlocks materially higher LTV (up to ~97%) for correlated baskets (stable/stable, ETH/LST) — game-changing for leveraged staking and stablecoin yield strategies.
Multi-asset architecture lets you deposit ETH and borrow any listed asset against it — Compound V3 forces one borrowable asset per market.
GHO native stablecoin gives Aave its own credit money supply, with discounts for stkAAVE holders.
Safety module — staked AAVE absorbs protocol shortfall events, an explicit on-protocol backstop Compound does not have.

Where Compound wins

Materially smaller attack surface — Compound V3's single-borrowable-asset design eliminates entire classes of cross-asset risk that Aave V3 has to model.
Better gas efficiency on borrow/repay/withdraw — V3 Comet typically costs 20-40% less gas than equivalent Aave V3 actions.
Cleaner mental model — one market, one borrowable asset, one collateral set. Easier to reason about for risk teams.
Longer continuous track record without any liquidation-engine failure or shortfall event.
Smaller, more focused governance surface — fewer parameters to vote on, fewer vectors for governance attacks.

Best for which user

Choose Aave if:

You want eMode for leveraged stable/LST strategies, multi-asset borrowing flexibility, GHO stablecoin access, or you need the deepest possible liquidity for size.

Choose Compound if:

You want a smaller blast radius, lower gas costs, and a simpler one-borrowable-asset-per-market architecture that's easier for risk teams to model.

Use both if:

You diversify counterparty risk across two of the longest-running DeFi money markets — same utility, different audit surfaces and shortfall histories.

Pricing detail

Both protocols charge no native protocol fee on deposits or borrows beyond the interest-rate spread between supply and borrow APRs (the spread is the protocol revenue, allocated to treasury / safety module). Effective borrow rates are utilization-curve-driven and very similar between the two protocols at comparable utilization. Aave's deeper liquidity means it stays below the kink-rate longer for large borrows.

Frequently asked questions

Is Aave bigger than Compound?

Yes. Aave's TVL across all chains is roughly $12-15B in 2026-05 vs Compound at $2-3B. Aave has been the larger of the two since 2021.

What is Aave eMode?

Efficiency mode (eMode) lets users borrow at much higher LTV (up to ~97%) when supplying and borrowing correlated assets (e.g., stable/stable, or ETH/LST). It is the basis of most leveraged-staking and stablecoin-yield strategies on Aave V3.

Why did Compound V3 limit borrowing to one asset per market?

V3 ("Comet") deliberately separates each borrowable asset into its own market (one for USDC, one for ETH, one for USDT, etc.). This eliminates entire categories of cross-asset risk and lets the protocol run with smaller per-market collateral risk parameters. The trade-off is less flexibility for users who want to borrow many things against one collateral set.

Is Aave's safety module a real backstop?

Yes — stakers in the Aave Safety Module commit AAVE (and other assets) to be slashed up to 30% in the event of a protocol shortfall, in exchange for staking rewards. It has not been invoked. Compound has no on-protocol equivalent.

What is GHO and is it stable?

GHO is Aave's native over-collateralized USD stablecoin. It is minted by users against collateral on Aave V3, with discounts for stkAAVE holders. GHO traded slightly off-peg for much of 2023; tighter Aave-DAO interest-rate management in 2024-2025 has kept it within ±0.5% of $1 in 2026.
