GHO and DAI are generated through collateral-backed protocols with governance-set rules; USDC is issued by Circle affiliates and has an issuer redemption promise. Those differences affect how tokens enter circulation, what supports them and how holders can convert them.
How GHO, DAI and USDC differ
| Stablecoin | How it is issued | What supports it | Conversion or redemption |
|---|---|---|---|
| GHO | Borrowers mint it against eligible collateral in Aave V3’s Ethereum market; approved facilitators can mint and burn within governance-set capacity limits. (Aave GHO Stablecoin help page and protocol documentation) | Overcollateralized protocol borrowing, subject to collateral requirements and facilitator caps. (Aave) | Aave’s Stability Module supports swaps with governance-approved stablecoins; its initial pricing strategy is fixed 1:1, but the framework is configurable. (Aave) |
| DAI | Users generate it by depositing governance-approved collateral in Sky Protocol Vaults. (Sky whitepaper) | Assets deposited in Vaults, with collateral-specific risk parameters set through governance. (Sky) | Protocol and market mechanisms support its dollar target; the cited Sky materials describe governance adjustments to the Dai Savings Rate, not a direct issuer promise to redeem every holder’s token for a dollar. (Sky) |
| USDC | Issued by regulated Circle affiliates. (Circle USDC materials) | Liquid fiat reserves held for holders’ benefit, including cash, bank deposits, short-term U.S. Treasury securities and overnight reverse repurchase agreements. (Circle) | Circle says USDC is redeemable 1:1 for U.S. dollars. Circle Mint is available to institutions, not individuals, so this is not a claim that every individual holder can redeem directly through Circle. (Circle) |
These are different ways to pursue a dollar target, not interchangeable guarantees. A protocol’s collateral and governance rules, an issuer’s reserve and redemption arrangements, and the market price at which a holder trades are separate considerations.
How GHO is created and managed
Aave describes GHO as a decentralized, overcollateralized stablecoin native to Aave, designed to maintain a value pegged to the U.S. dollar. Currently, users can borrow it against eligible collateral available in the Aave V3 Ethereum market. The amount available depends on collateral requirements as well as the capacity allocated to facilitators.
Facilitators are governance-approved entities or mechanisms that can mint and burn GHO up to their assigned bucket capacities. Unlike ordinary Aave reserve borrowing, GHO is minted rather than drawn from a pool of liquidity supplied by depositors. That makes facilitator limits part of the issuance design, alongside borrower collateralization.

Interest paid by GHO minters goes to the Aave DAO treasury, according to Aave. This is a protocol revenue and governance feature; it does not make borrowing free or establish that GHO is safer than another stablecoin.
Does GHO always trade at one dollar?
No. Aave’s Stability Module is intended to support the peg by enabling swaps between GHO and governance-approved stablecoins. Aave describes its initial strategy as fixed 1:1 pricing, while also allowing the framework to change through governance. A target price and a conversion mechanism do not guarantee that every GHO trade on every market will occur at exactly one dollar.

How DAI is generated under Sky
Sky’s current whitepaper describes Dai as generated, backed and kept stable through assets deposited in Sky Protocol Vaults. Governance approves which assets may serve as collateral and sets risk parameters for each accepted collateral type. DAI and GHO are therefore both collateral-backed, governance-dependent protocol stablecoins, but they operate under different collateral policies, contracts and governance arrangements.
Sky was formerly known as MakerDAO. Its current whitepaper distinguishes DAI from USDS: Sky introduced the Sky Savings Rate for USDS in 2024, while DAI and the Dai Savings Rate continue to coexist. DAI is not simply another name for USDS.

What the Dai Savings Rate does
The Dai Savings Rate (DSR) is a global parameter set through governance. Sky says governance can adjust it in response to deviations from the dollar target: lowering the rate may reduce demand when DAI is above target, while raising it may encourage demand when DAI is below target. Those are the protocol’s intended effects, not guaranteed outcomes; the rate can change and should not be treated as fixed.
How USDC’s issuer and reserves work
Circle says USDC is redeemable one-for-one for U.S. dollars and is backed by liquid fiat reserves held separately from Circle’s operating funds for holders’ benefit. Circle identifies cash, bank deposits, short-term U.S. Treasury securities and overnight reverse repurchase agreements among the reserve assets. This issuer-and-reserve model differs from GHO’s collateralized protocol issuance and DAI’s Vault-based generation.

Circle’s transparency page reported 74.1 billion U.S. dollars in circulation and 74.3 billion U.S. dollars in total reserves as of October 5, 2026. These are Circle’s dated, rounded figures, not a live balance or an independent comparative assessment. Circle says it has issued reports on reserve assets since 2018 and provides monthly third-party assurances that reserves meet or exceed USDC in circulation; those are Circle’s statements about its reporting and assurance process.
Circle’s 1:1 redemption statement describes the issuer’s redemption promise, not a guarantee that USDC will always trade at exactly one dollar on every exchange. Direct Circle Mint access is for institutions, not individuals; an individual’s ability to convert USDC depends on the exchange, service or other route they use.

How savings and yield fit into the designs
Aave’s sGHO
Aave documents sGHO as an ERC-4626 vault on Ethereum mainnet. A user deposits GHO and receives sGHO shares, whose value in GHO increases as yield accrues from an on-chain rate. Aave says deposits and withdrawals are instant, with no cooldown, slashing risk or rehypothecation of deposited funds. The rate is set by governance and can change.
An August 27, 2026 Aave governance post proposed changes to specified GHO borrowing rates and the Aave Savings Rate. It was a dated proposal, not evidence of the live rate today. No current numerical sGHO or GHO borrowing rate is established here.
DAI savings and USDC
DAI’s savings mechanism is the governance-controlled DSR described above; no current numerical DSR is established here. The Circle materials covered here do not establish a comparable savings feature or yield claim for simply holding USDC.
What this comparison can—and cannot—tell you
The useful comparison is about dependencies: GHO depends on Aave collateral rules, facilitator capacity and governance; DAI depends on Sky’s approved Vault collateral and governance parameters; USDC depends on Circle’s issuer, reserve arrangements and redemption channels. Each design also has exposure to risks relevant to its structure, including smart-contract, governance, collateral, liquidity, issuer, banking and regulatory risks.
These mechanisms alone do not establish which token is safest or best, and they do not show which has held its market price closest to one dollar over a comparable period. A sound price-performance or risk ranking would require aligned, current evidence rather than treating a target, a redemption statement or a collateral mechanism as proof of constant market value.
