What Is the GHO Stablecoin

GHO is a decentralized stablecoin introduced by the Aave team in 2022, pegged to the US dollar. Unlike centralized stablecoins such as USDT or USDC, Aave’s smart contract infrastructure enables stable issuance by overcollateralizing crypto assets. Users deposit assets like ETH or WBTC on the Aave platform; they then mint GHO in proportion to their collateral and can repay or burn GHO at any time.

Aave describes GHO as a “flexible, configurable decentralized stablecoin,” emphasizing the synergy between governance and smart contracts. The Aave DAO manages key parameters—including interest rates, discount ratios, and supply caps. This ensures system stability even in volatile market conditions.

GHO Design Mechanism: Overcollateralization and the Facilitator Model

GHO issues through a distinctive Facilitator model. Each Facilitator receives a “Bucket” capacity, which sets the upper limit for GHO minting. The Aave protocol serves as the initial Facilitator. Additional protocols or institutions can join in the future, establishing a multi-layered issuance structure.

This framework allows GHO to expand its supply flexibly while maintaining system-wide overcollateralization and security. The DAO governs the total GHO minted by Facilitators; any changes to capacity require a DAO vote.

Interest Rate and Discount Model: Flexible Management by Aave Governance

Aave Governance determines GHO’s interest rate through dynamic smart contract parameters rather than market supply and demand. Aave also introduced a Discount Model, which provides borrowing discounts to users who stake stkAAVE. For instance, a user with 1 stkAAVE can borrow up to 100 GHO at a preferential interest rate. This incentive strengthens Aave’s community engagement and encourages greater participation in staking and governance.

Price Stability Mechanism and Arbitrage Logic

GHO targets a $1 price. Two main mechanisms help maintain this stability:

• Arbitrage: If GHO trades below $1, users buy it at a discount and repay debt for profit. If GHO exceeds $1, users mint new GHO and sell it, driving the price back down.
• Governance controls: The Aave DAO can adjust lending rates, discount ratios, and Facilitator capacities to prevent supply imbalances or excessive expansion.

In addition, the Aave price oracle consistently values 1 GHO at $1. This approach helps maintain system stability and transparency.

GHO: Future Outlook

The growing adoption of Aave V3 positions GHO to become one of the most trusted stablecoins in DeFi. Compared to established options like USDC and DAI, GHO offers greater decentralization, flexible governance, and consistent stability across multiple blockchains.

Looking ahead, Aave DAO aims to further enhance GHO’s ecosystem through cross-chain Facilitators, dynamic collateral models, and mechanisms for distributing reserve interest.
