## Summary

Ondo Finance tokenises real-world assets (primarily US Treasuries) on-chain. OUSG is a tokenised short-term Treasury fund; USDY is a yield-bearing dollar product available to both accredited and, in some jurisdictions, retail users. Ondo products are integrated as collateral in Aave and used by protocols across Ethereum — making Ondo the leading DeFi-native RWA issuer alongside BlackRock's BUIDL.

Ondo Finance is the leading DeFi-native issuer of tokenised real-world assets (RWAs), with over $1 billion in tokenised Treasury and money market products on-chain as of mid-2026. While BlackRock's BUIDL brought institutional credibility to on-chain Treasuries, Ondo built the DeFi integration layer — making tokenised bonds usable as collateral in lending protocols and composable with yield strategies.

Ondo's two flagship products are OUSG (Ondo Short-Term US Government Bond Fund) — a tokenised fund holding US Treasuries, available to qualified purchasers — and USDY (US Dollar Yield), a yield-bearing dollar token with broader availability. Both generate yield from underlying Treasury and money market holdings, paid to token holders.

## OUSG and USDY explained

- OUSG: Tokenised access to a short-term US Government bond fund; primary institutional/accredited product
- USDY: Yield-bearing stablecoin-like token backed by Treasuries and bank deposits; broader geographic availability
- Yield source: Underlying Treasury coupon payments and money market returns — not crypto trading strategies
- Custody: Assets held with regulated custodians; on-chain tokens represent beneficial ownership claims
- DeFi integration: OUSG accepted as collateral on Aave; USDY used in lending and liquidity pools

## Ondo in the RWA DeFi stack

The RWA tokenisation stack in 2026 has three layers: issuers (BlackRock BUIDL, Ondo, Franklin Templeton, Superstate), distribution (DeFi protocols, broker-dealers), and utilisation (Aave collateral, Pendle fixed yield, structured products). Ondo sits at the intersection of issuer and distribution — creating products designed for DeFi composability from inception.

Competitors include Superstate (USTB), Franklin Templeton (FOBXX on-chain), and Maple Finance (institutional credit). Ondo's advantage is first-mover DeFi integration and the ONDO governance token's role in protocol incentives.
