USDY is Coming to the Sei Network
We are excited to announce that United States Dollar Yield (USDY), a tokenized note backed by short-term US Treasuries and bank deposits, is coming to the Sei network, an ultra-fast layer 1 blockchain providing high performance rails for digital asset markets.
USDY will be the first tokenized treasuries asset on the Sei network, one of the fastest-growing modular blockchain ecosystems, bringing institutional-grade onchain yield to its users for the first time.
Sei’s focus on speed, efficiency, and scalability, in combination with USDY’s high-quality structure, is set to unlock new financial opportunities at the intersection of real-world assets and performant DeFi infrastructure.
Why Sei?
Sei is a high-throughput chain capable of handling thousands of transactions per second. Its parallelized EVM execution model makes it uniquely suited for high-frequency trading, composability, and capital-efficient applications.
Deploying USDY on Sei gives developers and users access to a high-quality yield-bearing RWA that fits seamlessly into Sei’s growing DeFi stack. Whether used as treasury collateral, payment rails, or a base-layer yield primitive, USDY enhances Sei’s position as a foundational chain for RWA-enabled onchain finance.
Unlocking Yield Utility Across the Sei Ecosystem
The integration will bring powerful use cases to Sei, including:
- Treasury and Liquidity Management: Protocols and DAOs can park idle stablecoin liquidity in a yield-generating, transparent asset, improving capital efficiency.
- RWA-Backed Stablecoin-Like Utility: USDY offers a compliant, interest-bearing alternative to traditional stablecoins, usable across Sei-native applications and onchain payment flows.
- Composability in DeFi: With Sei’s fast block times and parallel execution, applications can easily integrate USDY into money markets, DEXs, and structured products, enabling innovative yield strategies backed by RWAs.
“By bringing USDY to Sei, we’re combining an institutional-grade product with a next-generation execution layer, enabling capital-efficient use cases for protocols, developers, and users alike,” said Nathan Allman, Founder and CEO of Ondo Finance.
“Ondo Finance is setting the standard for real-world asset tokenization, and we're thrilled to welcome USDY to the Sei ecosystem,” said Justin Barlow, Executive Director at the Sei Development Foundation. “Sei's breakthrough infrastructure with near instant finality and parallelized execution makes it uniquely suited for institutional-grade financial products, and USDY represents the exact kind of high-quality, composable yield primitive that will unlock new possibilities for developers building the next generation of onchain applications.”
Bringing Regulated Yield Onchain, for Everyone
The Sei network is rapidly establishing itself as a foundational layer for the next generation of performant, parallelized, and composable DeFi infrastructure. With its unique architecture and growing ecosystem of developers and applications, Sei is closing key gaps in the scalability of onchain finance, enabling faster, more efficient markets for users around the world.
Now, with USDY coming to Sei, Ondo Finance is bringing yield-bearing dollars to the heart of the modular finance movement.
