What Is USDY? Ondo Finance’s Yield-Bearing Token on Stellar – Explained
If you use LOBSTR or spend any time in the Stellar ecosystem, you may have started seeing USDY pop up – in the swap section, in campaign notifications, in token lists. It looks like a stablecoin, it trades close to $1, but it is doing something most stablecoins do not: it is quietly earning yield while you hold it.
This article explains what USDY actually is, who Ondo Finance is, why USDY ended up on Stellar, and how you can put it to work – including a look at a live LOBSTR campaign where you can earn a 5 USDY reward just for trying it out.
What Is USDY?
USDY stands for United States Dollar Yield. It is a token issued by Ondo Finance that is backed by short-term U.S. Treasuries and bank demand deposits. Think of it as a tokenized money market fund – your balance is pegged close to $1, but instead of sitting idle, it earns yield every day just by being held.
Unlike a regular stablecoin like USDC or USDT, which earn nothing for the holder, USDY passes real yield directly to you. The yield comes from U.S. Treasury bills – some of the most secure financial instruments in the world. There is no protocol token, no inflationary reward, no staking trick. The yield is backed by actual interest from government debt.
The way it works technically: USDY does not rebase (meaning your token count does not change). Instead, the price of each USDY token slowly rises over time, reflecting accumulated yield. If you bought USDY at $1.00 and held it for a year at 4.65% APY, each token would be worth around $1.0465. The yield is baked into the price.
Current yield: approximately 4.65% APY as of mid-2026, though this is variable and tracks U.S. Treasury rates.
Important note for U.S. readers: USDY is not available to U.S. persons or for sale or distribution in the United States due to regulatory restrictions. If you are based in the U.S., this token is not accessible to you directly. Non-U.S. users can access it freely via supported platforms including LOBSTR.
Who Is Ondo Finance?
Ondo Finance is one of the leading companies in the real-world asset (RWA) tokenization space – the growing sector focused on bringing traditional financial instruments like Treasury bills, bonds, and stocks onto blockchain networks.
Founded in 2021, Ondo has grown rapidly and by mid-2026 manages over $2.5 billion in total value locked across its products. USDY is their flagship retail product – permissionless, accessible without accreditation, and available across multiple blockchains.
Some credibility markers worth knowing:
- Institutional backing – Ondo is backed by major investors including Pantera Capital, Founders Fund, and others
- Regulated structure – USDY is issued by Ondo USDY LLC, a Delaware bankruptcy-remote entity, with Treasuries held through Morgan Stanley as broker-dealer
- Multi-chain presence – USDY is live on Ethereum, Solana, Stellar, Sui, Aptos, Mantle, and more
- $740M+ USDY supply across chains as of early 2026
This is not a random DeFi project. Ondo is positioning itself as the infrastructure layer for institutional-grade yield in crypto, and USDY is their most accessible product for everyday users.
Why Is USDY on Stellar?
Stellar has always been focused on payments, remittances, and low-cost cross-border transfers. It is fast, cheap, and globally accessible. But for a long time, one thing was missing: your idle balance earned nothing.
If you held XLM or USDC on Stellar waiting to make a payment or a swap, that capital was sitting dead. USDY changes that.
Ondo launched USDY on Stellar in September 2025 in partnership with the Stellar Development Foundation. The integration makes USDY available directly within Stellar-based apps including LOBSTR, Aquarius, Meru, Soroswap, and Decaf Wallet – meaning you do not need to bridge to Ethereum or use a separate wallet to access it.
The fit makes sense from both sides. Ondo gets global distribution through Stellar’s network of wallets serving users across 180 countries. Stellar users get a productive alternative to holding plain stablecoins. And LOBSTR – already the most popular Stellar wallet with over 1.3 million active users – becomes a direct access point for earning yield onchain.
How to Earn with USDY on LOBSTR
Getting started with USDY on Stellar is straightforward:
- Open LOBSTR – available at lobstr.co as a web wallet or mobile app (iOS and Android)
- Go to the Swap section – you can swap any Stellar token (XLM, USDC, or others) into USDY directly
- Hold USDY in your wallet – yield accrues automatically over time, reflected in the slowly rising token price
- No staking or locking required – you can swap back out at any time
The minimum to interact meaningfully with USDY is low – around $10 worth – making it accessible for Stellar users at any level.
USDY fits naturally into the Stellar ecosystem as a place to park idle capital between activities. Instead of holding USDC that earns nothing, you hold USDY and let it work quietly in the background.
Live Example: The LOBSTR USDY Campaign (June 5-18, 2026)
A great way to try USDY for the first time is a current campaign running directly through LOBSTR:
- Swap any Stellar token to 10+ USDY via the LOBSTR Swap section
- Hold 10+ USDY at snapshot time – 00:00 UTC on June 19, 2026
- Receive 5 USDY reward if you are among the first 3,000 eligible participants
- Total pool: 15,000 USDY allocated across the campaign
At current prices, you are putting in around $11-12 to qualify and receiving $5-6 back – roughly a 45-50% return on the swap cost, on top of the ongoing yield from holding USDY in the first place. It is a low-barrier way to get hands-on with how USDY works while earning a bonus for doing so.
This kind of incentive campaign is likely to repeat as Ondo continues expanding across the Stellar ecosystem – so even if you are reading this after June 18, it is worth keeping an eye on LOBSTR announcements for future opportunities.
Is USDY Worth Holding?
For non-U.S. Stellar users, USDY is one of the most straightforward yield-generating options available onchain right now. Here is an honest breakdown:
The case for it:
- Real yield backed by U.S. Treasuries – not token emissions
- No lockup, no staking, no active management required
- Backed by an established, well-funded issuer
- Native to Stellar – no bridging needed
- Fits naturally as a productive holding between DeFi activities
Things to be aware of:
- Yield is variable and follows U.S. Treasury rates – it will go up and down with the rate environment
- Not available to U.S. persons
- Like all onchain assets, it carries smart contract and custodial risk – Ondo’s structure is robust but not zero-risk
- Liquidity on Stellar is still growing – it is not as deep as on Ethereum or Solana yet
For anyone already active in the Stellar ecosystem who holds idle stablecoins, swapping a portion into USDY is a simple upgrade. You are not chasing high-risk DeFi yields – you are earning a steady, Treasury-backed return on capital that would otherwise sit idle.
