The globally leading RWA tokenization platform Ondo Finance has announced that its flagship product, the United States Dollar Yield (USDY), will officially launch on the Sei Network, becoming the first on-chain treasury asset deployed on this ultra-fast Layer 1 blockchain.
USDY is currently deployed on multiple blockchains, with a TVL exceeding $680 million, offering an annualized yield of 4.25% (updated monthly) to individual and institutional investors worldwide (excluding the U.S.). It combines the liquidity advantages of stablecoins with the high-grade investor protection mechanisms found in traditional finance. This native integration with Sei makes high-quality yields possible for the first time within this on-chain infrastructure capable of processing tens of thousands of transactions per second. As one of the most widely adopted on-chain treasury-like assets, the addition of USDY marks Sei's official foray into the institutional DeFi market.
“Ondo bringing USDY to Sei is a prime example of deeply integrating institutional-grade financial products with the next-generation execution layer, which will provide more capital-efficient new use cases for protocols, developers, and end users,” said Nathan Allman, founder and CEO of Ondo Finance.
Behind this integration is the rapid growth in market demand for RWA access on high-performance L1 blockchains. Sei Network has shown impressive performance in 2025, with an annual growth rate of 821%, and its TVL has surpassed $670 million. The addition of USDY will further accelerate this momentum, injecting high-quality treasury asset exposure on-chain for Sei and filling a critical gap in its DeFi modular financial products.
“As the industry benchmark for RWA tokenization, we are excited to officially welcome USDY to the Sei ecosystem,” said Justin Barlow, Executive Director of the Sei Development Foundation. “Sei's groundbreaking infrastructure offers near-instant finality and parallel execution capabilities, making it an ideal platform for institutional-grade financial products; USDY is precisely the type of high-quality, composable yield primitive that can unlock new possibilities for developers to build the next generation of on-chain applications.”
This integration not only advances Ondo Finance's mission of “making institutional-grade financial products more inclusive” but also affirms Sei Network's commitment to building high-performance digital asset market infrastructure. With the continued rise in stablecoin usage and on-chain treasury demand, the launch of USDY comes at a perfect time, providing not only high-quality yield primitives but also serving as an important catalyst for the next phase of on-chain finance.
