GHO is the native decentralized stablecoin of the Aave Protocol, launched on Ethereum mainnet in July 2023 and subsequently expanded to Arbitrum and Base networks. GHO operates as an over-collateralized stablecoin: users who supply assets to Aave (ETH, WBTC, stablecoins, liquid staking tokens) can mint GHO against their existing Aave collateral positions, paying an interest rate set by Aave DAO (the GHO Borrow Rate) rather than the market-determined supply rate. The key structural difference between GHO and MakerDAO’s DAI is where interest revenue flows: in Aave’s standard lending markets, interest paid by borrowers goes to lenders (liquidity providers). With GHO, all interest paid by GHO borrowers goes directly to the Aave DAO treasury — creating a new protocol revenue stream. stkAAVE (staked AAVE token) holders receive a discount on their GHO borrow rate (initially 20-30% discount), aligning incentives for AAVE stakers to mint and use GHO. The Facilitator system allows Aave DAO to authorize specific entities or smart contracts to mint and burn GHO up to approved capacity limits (“buckets”), enabling GHO to expand beyond just Aave lending markets to other DeFi integrations. As of 2024, GHO has expanded to Arbitrum and Base chains, with active Balancer and Curve liquidity pools, and is being positioned as a revenue-generating product central to Aave’s long-term business model.

- Governance: Aave DAO (interest rate, risk parameters, facilitators)
GHO vs. DAI Comparison
| Feature | GHO | DAI |
|---|---|---|
| Protocol | Aave | MakerDAO (Sky) |
| Collateral | Aave-supplied assets | CDP-specific collateral |
| Interest recipient | Aave DAO treasury | Maker treasury |
| Interest rate mechanism | DAO-set fixed rate | DAO-set stability fee |
| Token holder discount | stkAAVE → 20-30% discount | DSR for depositors (different) |
| Supply | ~$100-200M (2024) | ~$5B+ |
| Multi-chain | Yes (Arbitrum, Base) | Limited (USDS expanding) |
| DeFi composability | Growing | Excellent (6+ years) |
Facilitator System
The Facilitator system allows modular GHO expansion:
- Aave V3 Facilitator: Primary facilitator; Aave lending market minting
- FlashMinter Facilitator: Flash loan GHO minting (within same block)
- Future facilitators: Approved by Aave DAO; each has a “bucket” (max mint capacity)
- Bucket model: Each facilitator: approved capacity; can mint up to limit; DAO controls capacity
- Security: Limits systemic risk — no single facilitator can mint unlimited GHO
stkAAVE Discount Mechanism
- Standard GHO borrow rate: set by Aave DAO (e.g., 6%)
- stkAAVE holders: receive discount (e.g., 20% discount → pay 4.8%)
- Discount amount: proportional to stkAAVE amount vs. GHO borrowed
- Goal: incentivize AAVE token staking; align protocol users with governance
- Limit: maximum discount regardless of stkAAVE amount
