Ondo Finance Expands USDY to Sei Network, Enabling Global Access to Tokenized Treasuries

TLDR:

• USDY now operates on Sei Network, offering users Treasury-backed yields through fast blockchain infrastructure. 
• Non-U.S. users gain direct access to tokenized U.S. Treasuries without intermediaries via Sei’s platform. 
• Developers can integrate USDY as collateral and yield primitives into DeFi protocols across Sei ecosystem. 
• The deployment expands USDY’s multichain presence, reinforcing its role as a foundational RWA primitive. 

Ondo Finance has deployed its U.S. Dollar Yield Token (USDY) on Sei Network, marking another step in the platform’s multichain expansion strategy.

The integration brings tokenized U.S. Treasury exposure to Sei’s high-performance blockchain infrastructure. USDY represents the largest tokenized U.S. Treasuries product by total value locked.

This deployment enables both individual and institutional users to access yield-bearing dollar instruments through Sei’s fast execution layer.

High-Performance Infrastructure Meets Real-World Assets

Sei Network’s architecture provides near-instant finality alongside parallelized execution capabilities for financial applications.

The blockchain’s design supports high transaction throughput without compromising reliability or speed. USDY now operates natively on this infrastructure, offering users direct access to Treasury-backed yields.

The token delivers yield backed by short-term U.S. Treasuries and cash instruments. Non-U.S. individuals and institutions can access these tokenized securities without traditional intermediaries.

Sei’s performance capabilities enable capital-efficient operations for users managing Treasury exposure. The combination provides sustainable yield generation while maintaining price stability.

Ondo Finance’s President, Ian De Bode, commented on the strategic expansion in the official announcement. “Expanding Ondo USDY to Sei’s high-performance blockchain broadens global access to tokenized U.S. Treasuries,” he stated.

De Bode noted that individuals and enterprises can leverage this sustainable yield source on Sei. He described the move as a key step toward establishing USDY as a core primitive of onchain finance.

The Sei Development Foundation’s Executive Director, Justin Barlow, addressed the integration’s practical applications.

“Introducing Ondo USDY to the speed and throughput of Sei will give users access to a high-quality, Treasury bills backed asset,” Barlow explained.

He outlined potential uses, including borrowing, lending, cash management, and cross-border payments. Barlow characterized the addition as another step in bridging traditional finance and DeFi on performant infrastructure.

Developer Integration and DeFi Composability

USDY’s deployment on Sei unlocks new opportunities for protocol developers building financial applications. The token integrates with native Sei applications, enabling advanced yield strategies and treasury management solutions. Developers can incorporate USDY into capital market products with minimal friction.

The institutional-grade backing positions USDY as reliable collateral across multiple contexts. Lending protocols, trading platforms, and liquidity provision systems can utilize the token.

Sei builders gain access to productive collateral and treasury assets for protocol development. The seamless integration process accelerates deployment timelines for developers.

USDY’s composability extends into DeFi primitives across the Sei ecosystem. Protocol developers can build yield strategies leveraging the token’s Treasury backing.

The integration reduces complexity for teams incorporating real-world assets into decentralized applications. This accessibility supports innovation in onchain financial products.

The deployment continues USDY’s expansion across major blockchain networks. Each integration enhances accessibility for global users seeking Treasury exposure.

The growing multichain footprint reinforces USDY’s position as a foundational real-world asset primitive. Ondo Finance plans additional ecosystem partnerships to expand USDY’s utility on Sei Network.
