Las Vegas, Nevada - April 6, 2026.
Frax Finance announced today that its flagship stablecoin, frxUSD, is now live as a default borrowable asset on the newly launched Aave V4 protocol.
The integration positions frxUSD among a select group of stablecoins available from day one on Aave’s next-generation lending platform, reinforcing its status as a trusted digital dollar in decentralized finance (DeFi).
Key Takeaways
- Day-One Integration: frxUSD joins a limited set of stablecoins as a default borrowable asset on Aave V4’s Core Hub spokes (Main, Gold, Forex) and select Bluechip configurations.
- Liquidity Support: Frax governance greenlit up to $27.5 million in deployments to enhance liquidity and peg stability across Aave V4 and complementary vaults.
- Hub-and-Spoke Innovation: Aave V4’s new architecture preserves unified liquidity while allowing specialized risk parameters for different borrowing environments.
- DeFi Milestone: The launch highlights growing institutional-grade stablecoin adoption in decentralized lending, with frxUSD gaining immediate traction as a core asset.
Aave V4, which launched on Ethereum mainnet with a security-first, conservative configuration, introduces a modular hub-and-spoke architecture designed to maintain unified liquidity while enabling tailored borrowing environments.
Under the initial rollout, frxUSD serves as a borrowable asset in the Core Hub’s Main, Gold, and Forex spokes. Additionally, corefrxUSD is included in the Prime Hub’s Bluechip Spoke and the Plus Hub’s Ethena Ecosystem Spoke.
Frax Finance’s governance approved up to $27.5 million in deployments across Aave V4 and related Morpho vaults to bolster liquidity and maintain the stablecoin’s peg. The move underscores Frax’s commitment to deep integration in core DeFi credit markets.
“Launching on Aave V4 from day one is a strong signal of the secureness with which we built frxUSD,” said Sam Kazemian, founder and CEO of Frax Finance. “Aave is the most important credit market in DeFi, and V4 represents the next step in its evolution to bring the financial system on-chain. frxUSD being included at launch reflects our goal of becoming one of the default stablecoins used across lending, liquidity, and digital dollar payments.”
Aave Labs founder Stani Kulechov echoed the sentiment: “We’re excited to see frxUSD live from day one as part of the initial rollout of Aave V4. Strong stablecoin participants are essential to the next phase of DeFi, as onchain credit markets expand to support a much broader range of participants, assets, and markets.”
frxUSD, a fully collateralized, fiat-redeemable stablecoin, builds on Frax’s earlier FRAX architecture with enhanced transparency and real-world asset backing, including tokenized U.S. Treasuries. Its rapid adoption on Aave V4 has already positioned it as one of the fastest-growing stablecoins on the platform.
Conclusion
The integration of frxUSD into Aave V4 represents a significant step forward for both Frax Finance and the broader DeFi ecosystem.
As Aave evolves its protocol with modular design and Frax continues to expand frxUSD’s utility, users gain access to more efficient, transparent, and capital-efficient borrowing and lending options.
This collaboration signals increasing maturity in on-chain credit markets, where trusted stablecoins like frxUSD play a pivotal role in bridging traditional finance and decentralized infrastructure.
With strong governance backing and strategic liquidity support, frxUSD is well-positioned for sustained growth as a default digital dollar across DeFi platforms.
