United States Dollar Yield (USDY), the flagship yieldcoin from Ondo Finance, is now live on the Sei Network. This development marks the debut of the first permissionless tokenized U.S. Treasury Bill primitive on Sei, providing both retail users and institutions with direct access to a secure, institutional-grade asset backed by short-term U.S. Treasuries and bank deposits.
The Foundation for Institutional-Grade Assets
Sei Network is positioning itself as a global settlement layer for modern finance, offering high-performance and low-cost infrastructure suited for the demands of institutions, enterprises, and consumer finance. By deploying on Sei’s Parallelized EVM, Ondo Finance leverages infrastructure that delivers 400ms time-to-finality and 12,500 transactions per second (TPS), meeting the speed requirements of global markets.
With a circulating supply exceeding $1.2 billion, USDY reflects significant institutional demand and introduces one of the largest capital pools in the Real World Asset (RWA) sector to Sei. The tokenized treasury market, now valued at $10 billion, addresses the issue of idle cash, with corporate cash balances globally surpassing $8 trillion. USDY’s integration on Sei is designed to capitalize on this opportunity.
This integration strengthens Sei’s position as a preferred ecosystem for RWAs, aligning Ondo Finance with a growing list of asset managers and infrastructure partners who value the composability of assets in a high-velocity ecosystem like Sei. The Sei Network supports a rapidly expanding institutional asset ecosystem, including tokenized funds from major players such as BlackRock, Brevan Howard, and Apollo.
Unlocking Yield Utility Across the Sei Ecosystem
USDY transforms capital functionality by enabling users to convert idle cash balances into composable real-world assets. The integration allows seamless utilization of tokenized treasuries across the ecosystem, serving as high-quality collateral for decentralized finance (DeFi) lending, a stable foundation for institutional cash management, and a medium for global payments.
Key benefits for users include treasury-backed dollar exposure, global accessibility without intermediaries, and fast execution supported by Sei’s performance rails. For developers, USDY offers full ERC-20 composability, secure collateral, and seamless integration into DeFi protocols.
Live Integrations: USDY Utility on Day One
Ondo Finance has integrated USDY on Sei with immediate access across Sei’s DeFi ecosystem. Users can swap USDY on Saphyre, a Sei-native decentralized exchange (DEX), and utilize it as collateral on Takara Lend and Yei Finance. Additionally, USDY is accessible on Sei via LayerZero’s omnichain infrastructure, facilitating the movement of treasury-backed assets from other ecosystems into Sei’s high-performance environment.
These integrations enable USDY to function as an active, composable asset, ready for deployment across trading, lending, and cross-chain environments from launch. The launch of USDY on Sei signifies a step towards the convergence of traditional capital markets and the onchain economy.
