Decentralized finance (DeFi) continues to evolve with innovative solutions, and one of the most anticipated developments in 2025 is the testnet launch of GHO, Aave’s native overcollateralized stablecoin. After first proposing the project in mid-2023, Aave Labs has officially rolled out GHO on the Ethereum Goerli testnet, marking a significant milestone in DeFi’s push toward self-sustaining, protocol-issued stable assets.
This article dives deep into what GHO is, how it works, and how users can interact with it today—even before mainnet deployment. Whether you're a DeFi veteran or exploring decentralized borrowing for the first time, this guide will walk you through everything you need to know.
👉 Discover how decentralized borrowing is evolving with next-gen stablecoins like GHO.
What Is GHO?
GHO is a decentralized, overcollateralized stablecoin developed by Aave, one of the leading lending protocols in the DeFi ecosystem. Pegged 1:1 to the US dollar, GHO aims to enhance capital efficiency within the Aave platform by enabling users to mint a native stablecoin directly against their deposited collateral—without relying on external stablecoin liquidity.
Unlike third-party stablecoins such as USDC or DAI, GHO is fully integrated into the Aave protocol, allowing seamless borrowing, repayment, and governance participation. Its design emphasizes security, transparency, and decentralization, with all code and SDKs publicly available on the official documentation site.
How Does GHO Work?
GHO operates using an overcollateralization model similar to other DeFi lending mechanisms. Users deposit supported assets (like ETH, wBTC, or AAVE) into the Aave protocol and can then borrow GHO up to a certain loan-to-value (LTV) ratio. This ensures that every GHO in circulation is backed by more value in collateral than it represents.
The borrowing and repayment process is streamlined:
- Borrowing GHO: A single transaction allows users to mint GHO against their collateral.
- Repaying GHO: Upon repayment, the protocol automatically destroys the returned GHO tokens, reducing the total supply dynamically.
All interest generated from GHO loans flows directly into the AaveDAO treasury, reinforcing protocol-owned liquidity and long-term sustainability.
Key Features of GHO
- Protocol-controlled issuance: New GHO tokens are minted only when users borrow, ensuring demand-driven supply.
- DAO-governed interest rates: The AaveDAO sets and adjusts borrowing rates based on market conditions.
- StkAAVE holder benefits: Users who stake AAVE to receive stkAAVE earn exclusive perks, including reduced borrowing fees.
- Multi-collateral support: Multiple asset types can be used as collateral, increasing flexibility.
Interest Rates & stkAAVE Discounts
On the Goerli testnet, the base borrowing rate for GHO is set at 2%, though this may vary once live on mainnet. The real innovation lies in the discount mechanism for stkAAVE holders.
By staking AAVE tokens, users gain access to lower borrowing costs:
- For every 1 staked AAVE, users can borrow up to 100 GHO at a preferential rate.
- Maximum discount reaches 20% off the standard interest rate.
For example, to borrow 10,000 GHO at the lowest possible rate, a user must stake at least 100 AAVE. This incentivizes long-term participation and strengthens alignment between governance participants and protocol usage.
This tiered discount model promotes deeper engagement with Aave’s ecosystem while rewarding loyal users with tangible financial benefits.

How to Use GHO on Goerli Testnet
While GHO has not yet launched on Ethereum mainnet, early adopters can experiment with its functionality via the Goerli testnet. Here's a step-by-step walkthrough:
Step 1: Access the Testnet Interface
Visit the official test environment at gho.aave.com (note: link removed per guidelines; use OKX anchor below for engagement).
Step 2: Connect Your Wallet
Use MetaMask or any Web3-compatible wallet. Ensure it’s configured for the Goerli network.
Step 3: Get Test ETH
Acquire Goerli ETH from a faucet (e.g., Alchemy or Chainlink’s Goerli faucet) to cover gas fees.
Step 4: Deposit Collateral
Choose a supported asset (such as wETH or DAI) and deposit it into the Aave V3 pool on Goerli.
Step 5: Borrow GHO
Navigate to the GHO section and select “Borrow.” Confirm the transaction—your GHO tokens will appear instantly in your wallet.
Step 6: Repay and Burn
When ready, repay your loan in one click. The system will burn the repaid GHO, updating circulating supply in real time.

Frequently Asked Questions (FAQ)
What is GHO?
GHO is Aave’s native overcollateralized stablecoin, pegged 1:1 to the US dollar. It allows users to borrow against deposited collateral directly within the Aave ecosystem.
Is GHO live on mainnet?
As of now, GHO is available only on the Ethereum Goerli testnet. Mainnet deployment details will be announced by AaveDAO through official governance channels.
How is GHO different from DAI or USDC?
Unlike DAI (multi-collateral but managed by MakerDAO) or centralized USDC, GHO is issued natively by Aave, with interest revenue flowing back to AaveDAO. This enhances protocol sustainability and user alignment.
Can anyone mint GHO?
No—only users with sufficient collateral in Aave markets can borrow GHO. There is no direct minting; issuance occurs solely through borrowing activity.
Where does the interest go?
All interest paid on GHO loans is directed to the AaveDAO treasury, funding future development, security audits, and ecosystem incentives.
Do I need stkAAVE to borrow GHO?
No. Anyone can borrow GHO if they meet collateral requirements. However, stkAAVE holders receive discounted interest rates as a governance incentive.

Final Thoughts
The launch of GHO on testnet signals a new chapter for Aave—one where protocol-native assets enhance liquidity, governance engagement, and economic resilience. By integrating a stablecoin directly into its lending engine, Aave reduces reliance on external dependencies and creates a closed-loop economy that rewards active participants.
As we move toward broader adoption in 2025, watching how GHO performs under real-world conditions will be crucial. For now, testing on Goerli offers a risk-free way to explore the future of decentralized borrowing.
Stay informed, participate in governance, and prepare for a more autonomous financial ecosystem powered by innovations like GHO.
