Ondo's USDY is now live on Sei: a perfect combination of tokenized U.S. Treasuries and high-performance infrastructure

Ondo Finance Flagship Yield Token ------ USD Yield Token ( USDY ), a token backed by tokenized short-term U.S. Treasury bills, is now live on the Sei network.

As the first permissionless tokenized U.S. Treasury product launched on the Sei network, USDY provides retail and institutional users in the ecosystem with a direct, permissionless way to access secure, institutional-grade assets backed by short-term U.S. Treasury bills and bank deposits.

Institutional-Grade Asset Foundation

Sei is becoming the global settlement layer for modern finance—an infrastructure designed for the rigorous demands of institutional, corporate, and consumer finance, offering high performance and low costs. By deploying on Sei's parallelized EVM, Ondo leverages infrastructure that achieves 400 milliseconds final confirmation times and 12,500 TPS throughput, providing the certainty and speed required by global markets. With a market cap exceeding $1.2 billion, USDY demonstrates broad institutional demand and brings one of the largest pools of capital in the RWA space to Sei.

The tokenized Treasury market has evolved into a $10 billion market as it addresses a real-world problem: idle cash. Global corporate cash balances exceed $8 trillion, and the opportunity is just beginning—USDY is launched on infrastructure designed for future growth.

This integration further solidifies Sei's position as the preferred ecosystem for RWA (Real World Assets), with Ondo joining an increasing number of world-class asset management firms and infrastructure partners who recognize the value of bringing composable, efficient capital into a rapidly growing ecosystem like Sei.

This foundation supports a rapidly growing institutional ecosystem, including tokenized funds from BlackRock, Brevan Howard, Hamilton Lane, Nomura's Laser Digital, and Apollo, which are currently operating on the network. Major infrastructure partners such as Circle, Binance, Securitize, KAIO, and Etherscan also support this initiative.

Unlocking the Yield Potential of the Sei Ecosystem

USDY changes the way capital operates on Sei, converting idle funds into high-yield assets. Users and protocols no longer need to hold static stablecoins but can utilize USDY as a versatile financial building block.

The integration of USDY enables seamless value flow throughout the ecosystem—it can serve as high-quality collateral for DeFi lending, provide a stable foundation for institutional savings, and become an interest-bearing medium for global payments. By integrating these functionalities into a single institutional-grade asset, USDY simplifies liquidity management and expands the possibilities for decentralized finance on Sei.

Key Advantages for Users:

Yield-bearing dollar asset: Users can hold USDY to earn yields backed by short-term U.S. Treasury bills, combining sustainable yield generation with price stability.

Global accessibility: Non-U.S. individuals and institutions can access tokenized Treasuries directly on the Sei platform without intermediaries.

Fast execution: Sei's high-performance infrastructure supports efficient capital operations without compromising transaction speed or reliability.

Key Advantages for Developers:

• Full ERC-20 compatibility: USDY seamlessly integrates with Sei's EVM, supporting advanced yield strategies, capital management, and capital market products.
• Secure and efficient collateral: With institutional-grade backing, USDY serves as reliable collateral in lending, trading, and liquidity provision scenarios.
• Seamless integration: Sei developers can quickly integrate USDY into various DeFi protocols as efficient collateral, capital management assets, or yield-building components.

Ian De Bode, President of Ondo Finance, stated:

*"Expanding *Ondo USDY* to Sei's high-performance blockchain will broaden global user access to tokenized U.S. Treasuries. From individuals to enterprises, everyone can now leverage a high-quality, sustainable, and stable source of yield on Sei, supporting numerous use cases in the DeFi ecosystem. This is a crucial step in making USDY a core element of on-chain finance."*

Justin Barlow, Executive Director of the Sei Development Foundation, remarked:

*"Introducing *Ondo USDY* to Sei's high-speed, high-throughput platform will enable users to access a high-quality, U.S. Treasury-backed asset for lending, cash management, cross-border payments, and more. Ondo's entry into the Sei ecosystem is another key step in bridging the gap between DeFi and traditional finance, all powered by the world's best-performing crypto infrastructure."*

These integrations allow USDY to serve as active and composable capital, ready for trading, lending, and cross-chain strategies from day one.
