Introduction

Ondo US Dollar Yield (USDY) is a tokenized financial instrument that brings the returns of US Treasury Bills onto public blockchains. It is designed to give non-US investors a yield-bearing alternative to traditional stablecoins, combining dollar stability with real-world income from government-backed assets.

Unlike standard stablecoins that hold a fixed value and generate no returns for holders, USDY passes the yield from its underlying assets directly to token holders.

History & Background

Ondo Finance launched USDY to bridge the gap between traditional fixed-income markets and the growing real-world asset (RWA) tokenization sector. The product was originally issued through Ondo USDY LLC, a bankruptcy-remote special purpose vehicle (SPV) designed to protect investors if Ondo Finance itself faced financial difficulties.

In late 2025, Ondo USDY LLC was folded into the broader Ondo Global Markets umbrella, signaling the maturing of the product line within Ondo's expanding institutional offering.

How Ondo US Dollar Yield Works

When an investor deposits funds — via wire transfer, USDC, or USDT — Ondo uses those funds to purchase short-term US Treasuries or equivalent instruments. The resulting yield accrues to USDY holders.

There is a 40-50 day waiting period before newly minted USDY tokens become transferable on-chain. After this period, tokens can be used freely within eligible geographies, including in DeFi applications.

USDY comes in two forms:

  • Accumulating (USDY): The per-token price increases as yield accrues.
  • Rebasing (rUSDY): The price stays at $1.00, while the number of tokens in a wallet increases over time.

Tokenomics

USDY is not a fixed-supply speculative asset — its supply grows and shrinks with minting and redemption activity. The economic design prioritizes yield distribution over token appreciation, with returns flowing from the Treasury portfolio directly to holders. Investors can redeem their tokens daily, giving the token a highly liquid economic structure tied to the underlying asset value.

Ecosystem & Use Cases

USDY is deployed across multiple blockchains, making it composable with a wide range of DeFi protocols. Holders can use USDY as collateral, in liquidity pools, or simply as a yield-bearing store of value. Ondo has partnered with oracle networks like Pyth to bring accurate USDY price feeds to dozens of blockchains, further expanding its DeFi reach.

Team, Governance & Community

Ondo Finance is a US-based fintech and blockchain firm focused on institutional-grade tokenized finance. The project is centrally managed by the Ondo team, with asset custody and compliance handled through regulated partners. USDY does not have a community governance mechanism — decisions about the product are made by Ondo Finance as issuer.

Advantages

  • Real yield: Returns come from US Treasuries, not token inflation.
  • Bankruptcy-remote structure: The SPV design separates investor assets from Ondo's corporate risk.
  • Multi-chain accessibility: Available on major blockchains for wide DeFi integration.
  • No accreditation required: Open to qualifying non-US retail and institutional investors alike.
  • Two token formats: Holders can choose accumulating or rebasing based on their preferences.

Risks & Challenges

  • Geographic restrictions: USDY is not available to US persons, limiting its addressable market.
  • Regulatory uncertainty: Evolving global regulations around tokenized securities could affect access or structure.
  • Waiting period: The 40-50 day lock before transfer may deter investors seeking immediate liquidity.
  • Centralized issuance: As a centrally managed product, USDY depends on Ondo Finance's operational continuity.
  • Variable yield: Returns fluctuate with interest rate conditions and are not guaranteed.

Long-Term Vision

Ondo Finance aims to become a leading infrastructure layer for institutional-grade tokenized assets on public blockchains. USDY is central to this vision as an accessible, yield-bearing dollar instrument for global investors. As RWA tokenization grows and regulatory clarity improves, USDY is positioned to serve as a foundational building block for the next generation of on-chain capital markets.

Frequently Asked Questions

USDY (US Dollar Yield Token) is a tokenized note issued by Ondo Finance and secured by short-term US Treasuries and bank demand deposits. It is designed to offer non-US investors stablecoin-like accessibility combined with real yield from traditional finance.

USDY is available to qualifying non-US individual and institutional investors. It is explicitly not available for sale or distribution to US persons due to securities regulations.

Yield is generated from the underlying portfolio of US Treasuries and bank demand deposits held by the issuer. This yield accrues to token holders either by increasing the per-token price (accumulating version) or by increasing the number of tokens in the holder's wallet (rebasing version).

USDY is the accumulating version, where the token price rises as yield builds up. rUSDY is the rebasing version, where the price stays at $1.00 but the token quantity in a wallet grows over time to reflect earned yield.

Yes. After minting, there is a 40-50 day waiting period before USDY tokens can be transferred on-chain. Once this period has passed, tokens can be freely used in DeFi or transferred to eligible recipients.

USDY is deployed across multiple blockchains including Ethereum, Solana, Arbitrum, Aptos, Sui Network, Mantle, and Osmosis. This multi-chain presence allows USDY to be used across a wide range of DeFi ecosystems.

A standard stablecoin pegs its value to the dollar but generates no return for the holder. USDY maintains dollar-denominated value while also passing on real yield from US Treasuries, effectively functioning as a yield-bearing dollar instrument.

USDY was originally issued through Ondo USDY LLC, a special purpose vehicle (SPV) legally separate from Ondo Finance. This structure is designed to protect investor assets even if Ondo Finance were to face insolvency, though it has since been folded under Ondo Global Markets.
