About
What it answers, and for whom.
USDY and OUSG are Ondo Finance's two treasury-backed tokens, built for different holders. USDY is a tokenized note for investors outside the United States, secured by short-term US Treasuries and bank deposits. OUSG is a fund token for qualified purchasers that holds short-term Treasury funds, including BlackRock's BUIDL. This dashboard reads both tokens' supply, holders and prices on every chain they are issued on.
Both pay their yield through price rather than new tokens: the price of one USDY or OUSG rises as the assets behind it earn, and Ondo posts that price on-chain. Rebasing versions such as rUSDY keep a price of one dollar and grow the holder's balance instead. The dashboard converts rebasing balances back to the underlying token, so the same holding is never counted twice.
OUSG can be minted and redeemed with stablecoins at any hour through Ondo's instant manager contracts, including with RLUSD on the XRP Ledger. Those mints and redemptions are listed with their transactions beside the daily supply on each chain, so a reader can see when money came in or left.
Method
How it will be measured.
Every figure will be read at a block, kept with its source and its exact read, and open a receipt anyone can re-check.
How receipts work →- Supply is each token's totalSupply() at the last block of the day on every EVM chain, and the issued supply recorded by Solana, Sui, Aptos and the XRP Ledger on theirs, with bridged copies kept apart from native supply.
- Prices come from Ondo's on-chain price oracles for USDY and OUSG at the same block; their growth between two pinned blocks, annualized, is the yield each token has actually accrued.
- Rebasing rUSDY balances are converted to USDY through the wrapper's own share conversion and are never added on top of USDY supply.
- OUSG instant mints and redemptions are read from the instant manager's events, with the stablecoin paid in or out and the OUSG minted or burned.
- Holders are addresses with a non-zero balance at the same block. OUSG can only be held by approved addresses, while USDY moves between wallets after an initial holding period, so the two counts mean different things.

Questions
Questions people ask.
What is Ondo USDY?
USDY, or US Dollar Yield, is a tokenized note issued by Ondo for investors outside the United States. It is secured by short-term US Treasuries and bank demand deposits, and its price rises as that collateral earns interest.
What is OUSG?
OUSG is Ondo's tokenized short-term US Treasuries fund for qualified purchasers. It holds shares of short-term Treasury funds such as BlackRock's BUIDL and can be minted or redeemed with stablecoins at any hour through Ondo's contracts.
What is the difference between USDY and rUSDY?
USDY accrues its yield through its price, which rises over time. rUSDY wraps USDY at a price of one dollar and grows each holder's balance instead. They are the same asset, so the dashboard counts rUSDY as USDY.
How is USDY's yield measured here?
From its on-chain price: the price Ondo posts at two pinned blocks gives the growth between them, annualized. That is the yield already accrued, not the rate announced for the coming period.
Is USDY a stablecoin?
Not in the usual sense. Its price rises over time instead of staying at one dollar, and it is a debt instrument that cannot be sold to US persons rather than a payment token. In DeFi it is often used as a dollar that earns yield.
Which chains are USDY and OUSG on?
USDY is issued on Ethereum, Solana and several other chains, including Mantle, Sui and Aptos. OUSG is issued on Ethereum, Polygon, Solana and the XRP Ledger. The dashboard reads each chain's contract on its own and adds them up.
- Tokenized note
- A debt instrument issued as a token, giving the holder a claim on the issuer secured by named assets.
- Rebasing token
- A token whose balances change to pass on yield while its price stays at one unit, such as rUSDY.
- Qualified purchaser
- A US investor category with high investment thresholds, required to hold some private funds such as OUSG.
