GHO Stablecoin: How Aave's DeFi Dollar Works

GHO is a decentralized, overcollateralized stablecoin native to the Aave Protocol. Unlike centralized stablecoins such as USDC or USDT, GHO is minted directly by borrowers who deposit collateral into Aave’s lending markets. This gives GHO a fundamentally different architecture: supply is demand-driven, governance is onchain, and yield opportunities are built into the protocol itself through Savings GHO (sGHO).

Since launching on Ethereum mainnet in July 2023, GHO has grown to over 580 million tokens in circulation as of March 2026. It has expanded beyond Ethereum to Arbitrum, Base, and Avalanche, and is positioned to become a core settlement asset within Aave’s upcoming V4 architecture. This guide covers how GHO minting works, the facilitator model, sGHO staking, current rates, multichain availability, and how it compares to other DeFi stablecoins.

GHO is not purchased on an exchange and then circulated—it is minted into existence when borrowers take out a position on Aave. The process is straightforward: a user deposits approved collateral (ETH, WBTC, stETH, or other Aave-supported assets) into the protocol and borrows GHO against it at rates set by Aave Governance.

This is an overcollateralized model. Borrowers must maintain a collateral ratio above the liquidation threshold for their deposited asset. If the collateral’s value drops below that threshold, liquidators can repay part of the GHO debt and claim discounted collateral. This mechanism ensures every GHO token in circulation is backed by onchain assets worth more than $1.

When borrowers repay their GHO debt, the tokens are burned. This mint-and-burn cycle means GHO supply directly reflects borrowing demand across Aave’s markets. Unlike algorithmic stablecoins, there is no unbacked expansion—every token traces back to real collateral locked in the protocol. For a broader comparison of how different stablecoins maintain their peg, see our guide to stablecoins on Ethereum.

One important distinction: interest paid by GHO borrowers does not flow to depositors as it does with other Aave assets. Instead, 100% of GHO borrow interest flows to the Aave DAO treasury. This creates a direct revenue stream for the protocol and aligns GHO’s growth with Aave’s long-term sustainability.

GHO uses a facilitator model that makes it more flexible than a single-source stablecoin. A facilitator is any entity or protocol authorized by Aave Governance to mint and burn GHO, each operating within a predefined bucket capacity that limits how much GHO they can create.

The primary facilitator today is the Aave V3 Ethereum Market. When users borrow GHO on Aave, this facilitator handles the minting. But the architecture allows for additional facilitators to be approved through governance. This could include RWA-backed facilitators, credit protocols, or institutional desks—each with their own risk parameters and bucket limits.

The bucket capacity is a critical safety mechanism. Even if a facilitator is compromised, the maximum exposure is capped at its approved bucket size. Aave Governance controls bucket allocations, allowing the DAO to scale GHO supply incrementally as confidence in each facilitator grows.

For cross-chain deployments, Chainlink’s Cross-Chain Interoperability Protocol (CCIP) serves as a facilitator for bridging GHO across networks. This approach avoids the fragmentation of wrapped tokens that plagues many multichain stablecoins—GHO remains a single, fungible asset regardless of which chain it’s on.

Savings GHO (sGHO) is Aave’s yield-bearing wrapper for GHO holders. By depositing GHO into the sGHO contract, users earn yield generated from GHO-borrowed interest without any lockup period or complex staking requirements. Withdrawals are instant—users can redeem sGHO for their original GHO plus accrued rewards at any time.

The sGHO yield currently sits in the 5–7% APY range, though this fluctuates with GHO borrow demand and rates set by governance. The yield source is straightforward: a portion of the interest paid by GHO borrowers is redirected to sGHO holders. This makes sGHO’s yield directly tied to protocol revenue rather than external incentives or emissions.

From a risk perspective, sGHO is relatively conservative compared to most DeFi yield products. Deposited GHO is not rehypothecated or lent out to third parties. There is no slashing mechanism on sGHO deposits. The primary risks are smart contract risk (inherent to any DeFi protocol) and GHO’s peg stability. For users looking for passive yield on stablecoins, sGHO is one of the cleaner options in DeFi—see our comparison of stablecoin DeFi platforms for alternatives.

sGHO is available on Ethereum, Arbitrum, Base, and Gnosis, with liquidity incentives active on several partner platforms.

Beyond sGHO, Aave’s V4 upgrade introduces stkGHO—a staked version of GHO within the Umbrella safety module. stkGHO offers higher yields (approximately 8% APY based on early parameters) but comes with a trade-off: staked GHO can be slashed if the protocol experiences a deficit event.

This creates a two-tier yield structure for GHO holders. sGHO offers a safer, no-lockup yield for passive holders. stkGHO offers higher returns for users willing to backstop the protocol’s solvency. Both options keep GHO productive without requiring users to actively manage positions on external DeFi lending platforms.

Unlike other assets on Aave where borrow rates are determined algorithmically by utilization, GHO borrow rates are set directly by Aave Governance through onchain proposals. This gives the DAO precise control over GHO supply expansion. When the DAO wants to encourage minting (to grow supply or support peg stability), it can lower rates. When it wants to tighten supply, it raises them.

AAVE token holders who stake in the Safety Module receive a discount on GHO borrow rates. At launch, this discount was set at 30% off the base rate. The discount mechanism incentivizes AAVE staking while making GHO borrowing cheaper for users who are already committed to the protocol’s security. Both the base rate and discount percentage are adjustable through governance.

All interest paid by GHO borrowers flows directly to the Aave DAO treasury. This is a significant revenue driver—with over 580 million GHO in circulation, even modest borrow rates generate meaningful protocol income. This revenue model underpins Aave’s ability to fund sGHO yields, safety module rewards, and ongoing protocol development.

GHO launched on Ethereum mainnet and has since expanded to multiple chains through governance-approved facilitators using Chainlink CCIP. As of early 2026, GHO is available on:

Ethereum: The primary chain for GHO minting via the Aave V3 Market. All collateral-backed minting originates here.

Arbitrum: GHO is bridged via CCIP with active liquidity programs. sGHO is also available on Arbitrum.

Base: Deployed in late 2025, GHO on Base benefits from Coinbase’s ecosystem and low transaction costs. sGHO is supported.

Avalanche: Governance-approved CCIP facilitator enables GHO bridging to Avalanche’s C-Chain.

The V4 Hub-and-Spoke architecture is expected to further simplify multichain GHO deployments. Each Hub will treat GHO as a native asset, while Spokes handle chain-specific lending rules. This means new chain deployments won’t require separate governance proposals for each facilitator—the Hub manages cross-chain liquidity centrally. For swapping GHO across chains, see our guide to stablecoin swap platforms.

Aave V4 cleared its governance vote with unanimous support in March 2026, with over 645,000 AAVE tokens cast in favor. The upgrade has significant implications for GHO.

V4 introduces a Unified Liquidity Hub that connects individual lending markets (called Spokes). Each Spoke operates with independent risk parameters and collateral policies, but they share liquidity through the Hub. GHO sits at the center of this architecture as the native settlement asset—every Spoke can mint, borrow, and settle in GHO without fragmenting liquidity across isolated pools.

The practical impact: GHO gains natural demand from every V4 deployment. Spokes built for RWA credit lines, institutional lending, or specialized collateral types all funnel activity through GHO. A revamped liquidation engine improves capital efficiency, meaning borrowers can mint more GHO per dollar of collateral. And deeper GHO integration means the stablecoin benefits from V4’s cross-chain liquidity hub rather than relying solely on CCIP bridges.

GHO is fully governed by the Aave DAO. AAVE token holders vote on all critical parameters: borrow rates, facilitator approvals, bucket capacities, discount rates for stakers, sGHO yield allocation, and cross-chain deployment decisions. There is no centralized issuer, admin key, or foundation with unilateral control over GHO supply.

This governance model means GHO parameters can adapt to market conditions.

During periods of peg instability in late 2023 and early 2024, governance raised borrow rates to reduce minting pressure and bring GHO back to its $1 target. As the peg stabilized and demand grew, rates were adjusted downward to encourage expansion. The ability to fine-tune rates through governance gives GHO a level of monetary policy flexibility that most stablecoins lack.

The DeFi stablecoin landscape includes several overcollateralized and yield-bearing options. Here is how GHO compares to other protocol-native stablecoins across key dimensions.

For a deeper look at how these platforms compare for earning yield, see our guide to stablecoin lending platforms. For a comparison with Sky Protocol’s approach, read our USDS guide.

GHO carries risks that users should understand before minting or holding. Smart contract risk is always present—Aave’s contracts are heavily audited, but no DeFi protocol is immune to undiscovered vulnerabilities. Peg stability is another factor. GHO has traded slightly below $1 during periods of low demand or high sell pressure, though governance has mechanisms to correct this through rate adjustments.

Borrowers face liquidation risk. If the value of deposited collateral falls below the required threshold, positions are liquidated. This is standard for overcollateralized lending, but users should monitor their health factor, especially during volatile markets. Governance risk also exists—since AAVE holders control all GHO parameters, poor governance decisions could, in theory, harm peg stability or protocol solvency.

For stkGHO specifically, slashing risk is a real consideration. If Aave’s protocol incurs a deficit, staked GHO in the Umbrella module can be partially slashed to cover losses. This is the trade-off for the higher yield stkGHO offers compared to sGHO.

GHO is a decentralized, overcollateralized stablecoin native to the Aave Protocol. It is minted by borrowers who deposit collateral into Aave’s lending markets and borrow GHO against it. GHO is pegged to the US dollar and governed entirely by AAVE token holders through onchain governance.

The primary method is depositing GHO into the sGHO (Savings GHO) contract, which earns 5–7% APY from GHO borrow interest. Users looking for higher yields can stake GHO via stkGHO in the Umbrella safety module for approximately 8% APY, though this carries slashing risk.

GHO is available on Ethereum (primary minting chain), Arbitrum, Base, and Avalanche. Cross-chain bridging is handled by Chainlink CCIP through governance-approved facilitators. sGHO is also available on Arbitrum, Base, and Gnosis.

What is the difference between sGHO and stkGHO?

sGHO is a passive yield product with no lockup, no slashing, and instant withdrawals—lower risk, lower yield (5–7% APY). stkGHO is staked in Aave’s Umbrella safety module, offering higher yield (~8% APY) but with slashing risk if the protocol incurs a deficit. sGHO is for yield; stkGHO is for yield plus protocol backstop.

No. GHO is overcollateralized, meaning every GHO token is backed by onchain assets worth more than $1 deposited in Aave. Borrowers must maintain collateral above liquidation thresholds. GHO does not rely on algorithmic mechanisms to maintain its peg.

GHO uses multiple peg stability mechanisms. Governance-set borrow rates can be raised to discourage minting and reduce supply when GHO trades below $1, or lowered to encourage minting when demand is high. Arbitrageurs also help—when GHO trades below $1, borrowers can buy cheap GHO to repay loans, reducing supply and pushing the price back up.

GHO is governed by the Aave DAO. AAVE token holders vote on all parameters including borrow rates, facilitator approvals, bucket capacities, and cross-chain deployments. There is no centralized issuer or admin key.

Facilitators are entities authorized by Aave Governance to mint and burn GHO, each within a capped bucket capacity. The primary facilitator is the Aave V3 Ethereum Market. This modular design allows governance to approve specialized facilitators (for RWAs, institutional lending, or cross-chain bridges) while limiting risk through bucket caps.

GHO represents a different approach to stablecoins—one where the issuer is a DAO, the supply is governed onchain, and yield is built into the protocol. With over 580 million tokens in circulation, multichain availability, and deep integration planned for Aave V4’s Hub-and-Spoke architecture, GHO is positioned as core DeFi infrastructure rather than just another stablecoin.

For users, the practical appeal is clear: mint GHO by borrowing against existing Aave positions, earn passive yield through sGHO, or backstop the protocol for higher returns via stkGHO. For the Aave ecosystem, GHO creates a sustainable revenue model that funds protocol development and safety module rewards, and generates sGHO yields in a self-reinforcing cycle.

Whether GHO can compete at scale with DAI, USDS, and centralized stablecoins depends on Aave V4 execution and continued governance discipline. But the foundation—overcollateralized minting, modular facilitators, and a built-in savings product—gives GHO a solid structural advantage in the DeFi stablecoin market.
