USDY: Tokenized US Treasury Bills Are Coming to Sei

The Sei Development Foundation is thrilled that Ondo Finance is bringing USDY, its flagship tokenized US Treasury Bills product to Sei. This represents a major milestone in Sei’s ecosystem development that brings institutional-grade RWAs to the fastest L1 blockchain, and signals a recognition of institutional readiness.

USDY is the second most adopted tokenized treasury product, representing over 32% of the entire tokenized treasury user base. USDY has served as a clear indicator of demand for robust, composable RWA assets, with the fifth highest TVL trailing the likes of only BUIDL by Blackrock, BENJI by Franklin Templeton, USTB by Superstate, and Ondo’s own permissioned product, OUSG.

Now, USDY, an institutional-grade RWA with clear demand and demonstrated utility, is coming to Sei.

Why This Matters

The Sei ecosystem saw an 821% year-over-year TVL growth, exceeding $670M, with a growing number of developers building on Sei's high-performance infrastructure. The upcoming USDY integration represents the next phase of Sei's evolution: solidifying Sei as the high-performance rails powering institutional-grade financial products.

Demand for RWAs reflect ecosystem maturation, with users in search of institutional-grade assets they can deploy as more sophisticated financial levers. 

What Changes for Developers

Today, developers on Sei lack direct access to tokenized treasuries. Any exposure requires navigating through multiple protocols, adding complexity and risk. USDY changes this paradigm entirely.

The upcoming launch of USDY on Sei brings:

• An Institutional-grade asset backed by US Treasuries
• Full ERC-20 composability on Sei's EVM
• Productive collateral for DeFi protocols seeking safe, yield-bearing assets

Whether you're building DeFi protocols, institutional treasury management, or next-gen financial applications, developers can now integrate treasury-backed assets directly into their products.

The Integration Path

Ondo Finance and the Sei Development Foundation will work closely with the ecosystem to ensure seamless USDY integration. As one of the most widely-adopted tokenized Treasury assets with over $680M TVL across multiple blockchains, USDY brings proven institutional demand to Sei's infrastructure.

What's Next

The introduction of tokenized US Treasuries like USDY on Sei is the start of a new era of onchain finance.

Sei is more than just the fastest L1, it's becoming key infrastructure for institutional finance. With sub-second finality, parallel execution, and now institutional-grade assets, Sei provides the foundation for the next generation of financial applications.

Markets Move Faster on Sei.
