- Aave Labs proposes integrating BlackRock’s BUIDL with the GHO Stability Module (GSM).
- The update aims to improve capital efficiency and expand yields from real-world assets.
- BUIDL integration would enable 1:1 USDC swaps, monthly dividend payments, and seamless transfers.
To strengthen its stablecoin infrastructure, Aave Labs has published a temperature-check proposal to update the GHO Stability Module (GSM). The proposal recommends integrating BUIDL — a tokenized fund managed by BlackRock — into the GSM architecture. The intent is to leverage traditional financial assets on-chain to optimize capital efficiency and broaden Aave’s sources of yield.
Optimizing GHO Stability through BUIDL Integration
The primary objective of Aave Labs’ proposal is to boost the capital efficiency of the GHO Stability Module by integrating BlackRock’s BUIDL token. Today, the GSM preserves GHO’s stability by maintaining 1:1 redeemability with a backing asset, typically USDC. Under the current setup, excess USDC can remain idle. The proposed change would create a new GSM instance designed to support external integrations and governance controls, specifically to incorporate BlackRock’s BUIDL — a tokenized fund on Ethereum that represents cash and U.S. Treasury holdings.
By using surplus USDC to mint BUIDL tokens, the revised GSM seeks to generate additional yield while preserving the high-standard backing provided by USDC. BUIDL offers several advantages, including on-chain exposure to traditional financial assets, active management by BlackRock Financial Management Inc., custody by BNY Mellon, and audited fund reporting by PwC. Each BUIDL token is priced at $1 and accrues daily dividends that are distributed to holders as newly minted tokens each month. This arrangement allows holders to earn yield while retaining custodial flexibility and 24/7 token transferability on-chain.
Future Outlook and Technical Specifications
Integrating BUIDL into the GSM could open new revenue streams for Aave DAO by expanding into real-world assets (RWA) and deepening potential collaboration with BlackRock. The proposal envisions maintaining a 1:1 fixed exchange ratio between USDC and GHO, while allocating surplus USDC to mint BUIDL tokens. The setup is intended to mirror the experience of the existing GHO:USDC GSM: swaps remain seamless, swap fees accrue to GHO, and dividends are paid out through BUIDL.

The technical changes would include updates to the GSM contract code to support GHO <> USDC conversions and the receipt and distribution of dividends. Additionally, BUIDL holders would need to be registered or whitelisted, which requires further adjustments to the GSM’s operational model. Detailed specifications will be provided during the ARFC phase; the proposal is currently seeking community feedback. If the community reaches consensus, the proposal would proceed to a snapshot vote and, if approved, move into the ARFC stage for final implementation.
Overall, the proposal represents a notable step toward combining traditional financial instruments with blockchain-native stablecoin mechanisms. If adopted, it could improve capital efficiency, increase yields available to GHO holders, and strengthen Aave’s strategic partnerships with institutional players.
