Ondo’s Tokenized U.S. Treasuries Go Live on Sei

Tokenized U.S. Treasuries from Ondo Finance are now live on the Sei Network, marking a major step forward for real-world assets (RWA) in decentralized finance.

USDY, Ondo’s flagship tokenized U.S. Treasury token, has already gained adoption as one of the most used tokenized Treasury products in the market, with over $1.2 billion in circulation. The integration brings this substantial liquidity to one of the fastest layer-1 blockchains, unlocking fresh opportunities for users, builders, and institutions around the world.

USDY’s launch on the Sei Network represents a major expansion of Sei’s RWA capabilities. As a high-performance blockchain designed to power global on-chain finance, Sei now supports access to the largest tokenized U.S. Treasuries by total value locked (TVL). According to announcements from both projects, USDY brings with it over $680 million in TVL on Sei, making it the first tokenized Treasury asset of its scale on the network.

This integration enables users to deploy USDY not just as a stable asset, but as a yield-bearing instrument tied to U.S. Treasuries and bank deposits. That means users can tap into traditional fixed-income yield onchain and in real time, bridging a gap between DeFi and traditional finance that many builders have long sought to solve.
