GHO vs DAI: Aave and MakerDAO Stablecoins Compared

GHO vs DAI Overview

GHO and DAI are the two largest decentralized, overcollateralized stablecoins on Ethereum. Both are minted by users depositing collateral into DeFi protocols rather than redeemed 1:1 from a centralized issuer like Circle or Tether. The similarities end there: GHO is minted through Aave borrowing positions, while DAI is minted through MakerDAO (now Sky Protocol) vaults. Each protocol takes a fundamentally different approach to rate-setting, governance, collateral management, and multi-chain expansion.

The following table provides a high-level snapshot. Each dimension is explored in detail throughout this guide.

Minting Mechanics

The core difference between GHO and DAI is how new tokens enter circulation. GHO is minted as a borrowing action within Aave, while DAI is minted by opening a dedicated vault in MakerDAO.

How GHO Minting Works

GHO is a native asset of the Aave protocol. Users who already have collateral deposited in Aave V3 or V4 markets (ETH, WBTC, LINK, and other supported assets) can borrow GHO directly against that collateral. GHO does not require a separate CDP or vault: it uses the same collateral pool that backs all Aave borrowing. When a user repays their GHO debt, the tokens are burned.

Aave controls GHO supply through a facilitator model. Each facilitator is a whitelisted contract or entity authorized by Aave DAO to mint and burn GHO, subject to a per-facilitator cap called a "bucket capacity." Four facilitators are currently active:

• Aave V3 Facilitator: primary collateral-backed minting on Ethereum
• CCIP Cross-Chain Facilitator: bridges GHO to Arbitrum, Base, and Avalanche via Chainlink CCIP
• GHO Stability Module (GSM): enables direct mint/burn at predetermined ratios for peg stability
• FlashMint Facilitator: allows flash-loan-style GHO minting and burning within a single transaction

How DAI Minting Works

DAI is minted by depositing collateral into a Maker Vault (formerly called a Collateralized Debt Position). Each vault type specifies a collateral asset, minimum collateralization ratio, and stability fee. Users deposit ETH, WBTC, USDC, stETH, or other approved assets, then draw DAI against that locked collateral. Returning the DAI (plus accrued stability fees) unlocks the collateral.

MakerDAO also operates a Peg Stability Module (PSM) that allows users to swap USDC for DAI at a fixed 1:1 rate, providing a hard floor for the DAI peg. The PSM acts as an arbitrage mechanism: if DAI trades above $1, arbitrageurs mint DAI via the PSM and sell it. If DAI trades below $1, they buy DAI and redeem it for USDC.

Collateral and Liquidation

Both protocols require overcollateralization, but they structure collateral management differently.

GHO inherits Aave's risk parameters. Collateral LTV ratios range from approximately 75% for ETH down to 35-40% for more volatile assets. Liquidation triggers when a borrower's Health Factor drops below 1.0, at which point liquidators can repay up to 100% of the GHO position and claim collateral plus a liquidation bonus. Because GHO shares the Aave collateral pool, a user's GHO borrow is just one liability among their overall Aave position.

DAI uses isolated vaults per collateral type, each with its own minimum collateralization ratio (typically 150-200%, depending on the asset's risk profile). Liquidation penalties range from 13-15%. Unlike Aave's shared-pool model, each Maker Vault is independent: liquidation of one vault does not affect another, even if both are held by the same user.

Interest Rates and Savings

GHO and DAI take opposite approaches to rate-setting. GHO uses a governance-set flat rate, while DAI's stability fees vary per vault type and change through governance votes.

GHO's borrow rate does not follow a utilization curve like other Aave assets. Instead, Aave DAO sets a fixed rate and delegates fine-tuning to GHO Stewards, who can adjust the rate within defined bounds (maximum 25% APR). This gives the protocol rapid peg-management capability: if GHO trades below $1, stewards can raise the rate to reduce supply, and vice versa.

DAI's stability fees function as interest rates on vault debt. These rates vary widely across vault types and have fluctuated significantly: ETH vault fees ranged from 1.5% to over 12% during 2025 alone. MakerDAO uses the DAI Savings Rate (DSR) as a complementary demand lever. With the rebrand to Sky Protocol, the DSR has been superseded by the Sky Savings Rate (SSR) for USDS holders, which reached 3.75% as of Q1 2026.

Anti-GHO and Staker Incentives

Aave introduced a novel mechanism to align AAVE stakers with GHO usage. The original stkAAVE discount (a direct borrow rate reduction for stakers) was replaced in March 2025 by the Anti-GHO system under the Aavenomics update.

Anti-GHO is a non-transferable ERC-20 token generated by AAVE and StkBPT stakers. Fifty percent of all GHO protocol revenue is allocated to Anti-GHO generation, with 80% directed to stkAAVE stakers and 20% to StkBPT stakers. Holders can either burn Anti-GHO 1:1 to repay GHO debt or convert it to stkGHO for yield (currently around 8.4% APY, subject to slashing risk in the Safety Module).

DAI/Sky takes a different approach to staker incentives. Protocol surplus flows into a buffer fund and, beyond that, into MKR buybacks and burns. Holders of USDS can deposit into the Sky Savings Rate contract (sUSDS) for yield without any slashing exposure, which has driven adoption: sUSDS deposits reached $6.49 billion by the end of Q1 2026.

Governance

Both stablecoins are governed by their respective DAOs, but the scope of governance power and the delegation structures differ.

Aave DAO controls all GHO parameters through on-chain AAVE token voting: borrow rates, facilitator approvals and caps, supply ceilings, and collateral risk parameters. The GHO Stewards function as a delegated committee with bounded authority to make rate adjustments without a full governance vote, enabling faster responses to peg deviations. Aave V4, which passed unanimously in March 2026 with 645,000+ AAVE votes, introduces a Hub-and-Spoke architecture designed to streamline multi-chain GHO deployment.

MakerDAO (now Sky Protocol) governance uses MKR token voting (or SKY, at a 1:24,000 conversion ratio) to control stability fees, collateral parameters, debt ceilings, and the SSR. Governance operates through two stages: Governance Polls (sentiment measurement) and Executive Proposals (binding on-chain votes). The Endgame plan envisions further decentralization through SubDAOs that manage specific protocol functions autonomously under the Sky DAO umbrella.

DAI's Evolution: USDS and Sky Protocol

MakerDAO rebranded to Sky Protocol in September 2024 as part of its Endgame roadmap. The rebrand introduced USDS as an upgraded version of DAI, convertible 1:1 in both directions. DAI remains fully functional and continues to be minted and redeemed, but USDS has become the protocol's primary stablecoin: its supply reached approximately $8.7 billion by mid-2026, surpassing DAI's ~$4.6 billion.

Major exchanges including Binance and Coinbase scheduled automatic 1:1 DAI-to-USDS conversions in April and May 2026, accelerating the migration. Native USDS has been deployed on Ethereum, Base, and Solana (via Wormhole NTT), with additional L2 deployments planned through 2026.

For users comparing GHO to the MakerDAO ecosystem, the relevant comparison is increasingly GHO vs. USDS rather than GHO vs. DAI, though the underlying vault mechanics and peg mechanisms remain the same.

Multi-Chain Availability

GHO launched as an Ethereum-only asset but has expanded to multiple chains through its CCIP facilitator. As of mid-2026, GHO is natively available on Ethereum, Arbitrum (since July 2024), Base, and Avalanche. The lock-and-mint model via Chainlink CCIP means GHO is locked on Ethereum and minted on the destination chain, preserving a single source of truth for total supply. Aave V4's Hub-and-Spoke architecture is expected to simplify further chain deployments.

DAI exists natively on Ethereum and is available as a bridged asset on all major EVM L2s: Arbitrum, Optimism, Base, Polygon, and others. Bridge security varies depending on the provider. USDS has native deployments on Ethereum, Base, and Solana, with Sky Protocol actively expanding to additional chains.

Neither GHO nor DAI is available on Bitcoin. Users who want decentralized stablecoin access on Bitcoin can explore Spark, which supports stablecoin transfers natively on the Bitcoin network.

Risk Comparison

Decentralized stablecoins carry risks that fiat-backed stablecoins do not: smart contract vulnerabilities, governance attacks, liquidation cascades, and oracle failures. Here is how GHO and DAI compare on key risk dimensions:

• Smart contract risk: DAI has been live since November 2019 with no critical exploits, establishing a strong track record. GHO launched in July 2023 and, while built on Aave's battle-tested codebase, has less time in production.
• Oracle risk: both rely on Chainlink price feeds. A sustained oracle failure could trigger incorrect liquidations or prevent necessary ones.
• Centralization risk: DAI's PSM and growing real-world asset allocation introduce dependence on USDC and off-chain custodians. GHO's facilitator model concentrates minting authority in governance-approved contracts.
• Peg stability: DAI has maintained a tight peg through multiple market cycles, including the March 2020 crash and the UST collapse. GHO traded below $1 for several months after launch before stabilizing through rate adjustments and the GSM.
• Regulatory risk: neither stablecoin has a regulated issuer. As jurisdictions define stablecoin frameworks, decentralized models face uncertain classification.

When to Use GHO vs DAI

Choose GHO if you already use Aave as your primary lending platform. Minting GHO does not require opening a separate vault or moving collateral: your existing Aave position serves as backing. The governance-set flat rate provides predictability, and stkAAVE holders benefit from Anti-GHO revenue sharing. GHO is also a natural fit if you operate on Arbitrum, Base, or Avalanche where native GHO is available via CCIP.

Choose DAI (or USDS) if you want a stablecoin with a multi-year track record, deeper DeFi integrations, and broader exchange support. DAI's market cap is roughly 8x larger than GHO's, which translates to better liquidity across trading pairs and lending markets. The Sky Savings Rate offers yield without slashing risk. USDS's expansion to Solana and major exchange support provide broader reach.

Frequently Asked Questions

Is GHO safer than DAI?

Neither is categorically safer. DAI has a longer track record (live since November 2019 with no critical exploits) and significantly larger market cap (~$4.6B vs. ~$600M). GHO benefits from Aave's battle-tested smart contract infrastructure and a more structured facilitator model. Both carry smart contract risk, oracle risk, and governance risk inherent to decentralized overcollateralized stablecoins.

What is the difference between DAI and USDS?

USDS is DAI's successor under the Sky Protocol rebrand. They are convertible 1:1 in both directions, and the underlying vault and collateral system is the same. USDS adds features like the Sky Savings Rate (SSR) and Sky Token Rewards (STRs). Major exchanges have begun automatically converting DAI balances to USDS. DAI continues to function but USDS is now the primary stablecoin of the Sky ecosystem.

Can I earn yield on GHO?

Yes. GHO holders can deposit into stkGHO (the Safety Module staking product) for approximately 8.4% APY, though this carries slashing risk if Aave experiences a shortfall event. AAVE stakers earn Anti-GHO tokens from protocol revenue, which can be burned to repay GHO debt or converted to stkGHO. A proposed sGHO product would offer 6-10% yield without slashing exposure.

What collateral can I use to mint GHO?

GHO can be minted against any collateral asset supported in Aave V3 and V4 markets: ETH, WBTC, LINK, AAVE, and other approved ERC-20 tokens. The collateral does not move to a separate vault: it remains in your Aave supply position, and your GHO borrow is one liability among your overall Aave position.

What is the GHO facilitator model?

GHO uses a facilitator model where specific contracts or entities are whitelisted by Aave DAO to mint and burn GHO. Each facilitator has a governance-defined cap ("bucket capacity") limiting how much GHO it can create. Four facilitators are currently active: Aave V3 (collateral-backed minting), CCIP (cross-chain bridging), GSM (peg stability), and FlashMint (same-transaction minting and repayment). This architecture allows controlled supply expansion without concentrating all minting authority in a single contract.

Is DAI fully decentralized?

DAI is one of the most decentralized stablecoins, but not fully decentralized in practice. Its Peg Stability Module depends on USDC, a centralized stablecoin. MakerDAO has increasingly allocated collateral to real-world assets (tokenized T-bills held through off-chain trustees), which introduces trust assumptions similar to fiat-backed models. Governance is controlled by MKR/SKY token holders, and voting power can be concentrated among large holders.

Which has lower borrowing costs: GHO or DAI?

GHO currently has lower borrowing costs. GHO's governance-set borrow rate sits around 6.75% on the Core instance, while DAI stability fees for ETH-backed vaults range from 12.50% to 13.25%. However, both rates change through governance votes and have varied significantly over time. DAI vault fees were as low as 1.5% at certain points in 2025 before governance raised them to manage risk.
