Aave and MakerDAO are the two longest-running lending protocols in decentralized finance, and both have evolved significantly heading into 2026. Aave has grown into a multi-chain money market offering variable-rate loans across more than a dozen networks, while MakerDAO completed its rebrand to Sky in 2024 and now issues USDS alongside the original DAI stablecoin. This comparison breaks down how each protocol works, what it costs to borrow, and which use cases fit each system.
Quick Comparison

| Native Token | AAVE (governance + staking) | MKR / SKY (governance) |
| Native Stablecoin | GHO | DAI and USDS |
| Supported Chains | 12+ (Ethereum, Polygon, Arbitrum, Base, Optimism, Avalanche, BNB, Metis, Gnosis, Scroll, zkSync, Linea) | Ethereum mainnet (primary); Spark sub-DAO multi-chain |
| Current Version | Aave V3 (V4 in rollout) | Sky Protocol (Endgame phase) |
| Borrow Rate Type | Variable (algorithmic) | Stability Fee (governance-set) |
| Liquidation Penalty | 5%–10% depending on asset | 13% standard |
| Governance | AAVE token voting | SKY token voting + SubDAOs |
How the Protocols Work
Aave operates as a pooled money market. Depositors supply assets like ETH, USDC, or wBTC into liquidity pools and receive interest-bearing aTokens that accrue yield in real time. Borrowers draw against their collateral at variable rates determined algorithmically by pool utilization. When utilization rises, borrow rates increase to incentivize repayment and new deposits, creating a self-balancing market.
MakerDAO, now rebranded as Sky, works differently. Users open a Vault (formerly called a CDP), deposit approved collateral such as ETH, wBTC, or tokenized real-world assets, and mint DAI or USDS against it up to a per-asset debt ceiling. There is no counterparty depositor — the stablecoin is minted from nothing and destroyed when the debt is repaid. Borrowers pay a Stability Fee set by governance, which in 2026 sits between roughly 5% and 12% depending on the collateral type.
The practical difference is liquidity versus flexibility. Aave lets you borrow dozens of listed assets, including volatile tokens. Sky only lets you borrow DAI or USDS, but it gives you a stablecoin whose peg is enforced by the protocol itself rather than by market arbitrage alone.
Fees, Rates, and Collateral Options
Aave’s variable rates adjust every block. As of early 2026, borrowing USDC on Aave V3 Ethereum typically ranges from 4% to 9% APR depending on utilization, while supplying USDC earns roughly 3% to 7%. Borrow rates for ETH are often lower, sometimes under 3%, since ETH demand for leverage is inconsistent. Aave charges no origination fee; revenue comes from a spread between supply and borrow rates plus a reserve factor retained by the DAO.
Sky’s Stability Fees are governance-set and tend to change less frequently. In early 2026, the ETH-A vault Stability Fee is roughly 7.25%, while tokenized Treasury-backed vaults carry lower fees to reflect their lower risk. Sky also runs the DAI Savings Rate (DSR) and the Sky Savings Rate (SSR) on USDS, which passes protocol revenue back to stablecoin holders — SSR has held between 5% and 12.5% over the past year.
Collateral variety favors Aave. The protocol lists more than 30 assets on Ethereum alone, including LSTs like wstETH and rETH, stablecoins, blue-chip altcoins, and a growing GHO ecosystem. Sky focuses on a narrower set of high-quality collateral: ETH, staked ETH variants, USDC through the PSM, wBTC, and real-world asset vaults that represent short-duration US Treasuries.
Security and Risk Profile
Both protocols have survived multiple bear markets without a protocol-level insolvency, which is rare in DeFi. Aave has been audited by firms including OpenZeppelin, Trail of Bits, Peckshield, and Certora, and runs a Safety Module where AAVE stakers backstop shortfall events in exchange for rewards. The module currently holds several hundred million dollars in AAVE and stablecoins as a last-resort insurance layer.
Sky’s main risk mitigation is its Surplus Buffer, a reserve of excess DAI generated from Stability Fees that absorbs bad debt before any SKY is minted and auctioned. The system also runs collateral auctions instantly on liquidation, which historically cleared even during the March 2020 crash, though that event did push the system into emergency mode and motivated the current liquidation engine design.
Users should weigh protocol-specific risks. Aave’s multi-chain footprint increases surface area — bridge failures or L2 outages can affect individual markets. Sky concentrates risk on Ethereum mainnet but is exposed to real-world asset counterparties as Treasury-backed collateral has grown to a material share of the backing.
Use Cases and Who Each Is Built For
Aave is the better fit if you want a money market experience: deposit, earn passive yield, and borrow flexibly against your portfolio. Its one-click flash loans, isolated markets for new assets, and eMode for correlated-asset leverage (for example, borrowing stETH against ETH at 90% LTV) make it the default choice for leveraged staking, liquidity mining, and cross-margin DeFi strategies.
Sky is better if your goal is specifically to mint a decentralized stablecoin against long-term collateral without selling it. The Endgame roadmap, still rolling out in 2026, is introducing SubDAOs such as Spark — a separate lending market built on Sky liquidity — that bridges some of the functional gap with Aave while keeping the core stablecoin issuer focused and conservative.
Final Verdict
Choose Aave if: you want a full-service money market, need to borrow multiple assets, use L2s actively, or run leveraged staking and cross-margin strategies. Its variable rates and wide collateral menu make it the more flexible tool for active DeFi users.
Choose MakerDAO (Sky) if: you want to mint a decentralized stablecoin against ETH or RWA collateral, prefer stable governance-set rates to algorithmic ones, or want yield on stablecoins via the DAI Savings Rate or Sky Savings Rate without lending to a variable-rate pool.
Frequently Asked Questions
Is Aave or MakerDAO safer?
Both have strong track records since 2017 with no protocol-level insolvency. Aave has a larger attack surface across multiple chains but runs a Safety Module for shortfall coverage. Sky concentrates on Ethereum mainnet but has growing real-world asset exposure. Neither is risk-free.
What is the difference between DAI and USDS?
Both are Sky-issued stablecoins pegged to the US dollar. DAI is the original, while USDS was launched in 2024 as part of the Endgame rebrand. They are convertible 1:1 through the protocol, but USDS is designed to be the primary long-term stablecoin.
Can I use Aave and MakerDAO together?
Yes. A common strategy is to mint DAI or USDS against ETH on Sky, then deposit that stablecoin into Aave to earn supply yield or use it as collateral. This is effectively stacking two lending protocols, but it adds composability risk.
What happened to the MKR token?
MKR holders can migrate to SKY at a 1:24,000 ratio as part of the Sky rebrand. MKR still exists and remains a valid governance token, but SKY is the protocol’s long-term governance asset with additional utility under the Endgame plan.
Which protocol has lower borrowing costs?
It depends on the asset. Aave’s variable rates for stablecoins are often lower than Sky’s Stability Fee during periods of low utilization, but Aave rates can spike above Sky’s fees when pools fill up. For long-duration borrowing, Sky’s predictable rates can be cheaper.
