What Are Saturn Credit's USDat and sUSDat | The Source of the 17% Yield and the Airdrop Terms

A displayed rate of 17% a year for depositing a stablecoin stands out as exceptionally high among dollar-denominated yields in DeFi. What makes Saturn unusual is that the money behind it comes not from inside the crypto market but from the dividends paid on STRC, a preferred stock that Strategy lists on Nasdaq.

As of August 20, 2026, however, one share of the yield-vault token sUSDat is worth 0.983341 USDat, still short of the one-to-one it started from at deposit.

The bet Saturn is making is to draw dollar yield out of the cash a listed company pays its shareholders rather than out of a mechanism internal to crypto. In exchange, a security whose price moves daily sits behind the principal.

There are two tokens to handle. USDat is a dollar-denominated token that carries no yield, and the yield rides only on sUSDat, which you receive by staking USDat.

In the official documentation, USDat is a permissioned stablecoin backed by M0's tokenized US Treasuries, and the interest it generates flows to Saturn's revenue vault rather than to holders. Anyone who wants the yield stakes USDat into sUSDat, and the dividends come back as a rise in the exchange rate rather than as more tokens.

Total deposits stood at $171.7 million on August 20, 2026, down 30.8% from the peak of $248.06 million on May 31, 2026. Of the USDat outstanding, 45.74% has been moved into sUSDat, and the rest is held without earning yield.

Depositing costs 0.10%, unstaking costs roughly the same, and leaving without sitting through a dividend cycle adds about 0.96%. The annual rate the app displayed on August 20, 2026 was 17.09%.

Among ERC-4626 vaults, the sUSDS of Spark takes the form of a share that keeps rising, while Saturn's is a share that moves up and down.

The near-fivefold gap between the yield figures corresponds directly to the difference between a design where the principal stays put and one where it moves.

No official document defines what the displayed annual rate includes; the STRC dividend rate recorded in the reserves is 12.0%, and the target stated in the official documentation is "11%+." In a July 28, 2026 article, Forbes pointed out that of the higher displayed yield at the time, 12 points came from dividends and the remainder depended on a recovery in the STRC price.

The multiplier changes a great deal with the form in which you hold.

The official documentation states that the points carry no monetary value, no claim on assets, and no transferability, and grant no right to any future token or airdrop. Residents of the United States, the EEA, the United Kingdom, and sanctioned jurisdictions cannot take part.

Strategy is. As of August 20, 2026, almost the entire backing of sUSDat consists of STRC.

STRC is a cumulative perpetual preferred stock that Strategy lists on Nasdaq. The issuer states that it pays a 12.00% annual dividend in cash on a semi-monthly basis.

Because the backing is an off-chain listed security, this mechanism cannot close on-chain alone. Saturn holds the STRC itself in a professional fund in the British Virgin Islands, with custody entrusted to Clear Street and fund administration to Securitize.

On the on-chain side it maintains two STRC price feeds, its own and Chainlink's, and computes the vault's total assets as "USDat balance + vested STRC x STRC price." Dividends received are streamed into the exchange rate over 30 days, which closes off the tactic of entering just before a dividend and leaving right after.

Synthetic dollars sourced from futures funding and the type that passes Treasury interest straight through are complete with just an order book and an interest rate. Saturn has to run three additional arrangements of its own outside that: holding the security, reflecting its price, and executing sales in the secondary market.

The strength of that conduit, though, is also the weakness of leaning on the credit of a single company. The official documentation itself says that if Strategy halts the dividend in harsh market conditions, the yield on sUSDat halts with it.

It adds that because STRC is cumulative there would be no default, but the price may drift away from par until the dividend resumes.

The STRC price on August 20, 2026 was $95.2511, 4.7% below the $100 par value.

Apyx Finance, which tokenizes and wraps the same STRC, is also running, and Protos reports roughly $136 million based on third-party aggregation. A three-chain deployment via Chainlink CCIP and integrations with Curve and Pendle are close to table stakes in this field.

Beyond the scenario where the dividend stops, there are three specific points of friction: the exit, the timing, and the paperwork.

When does money you unstake come back

Unstaking works like a queue of limit orders. When you request it, an NFT representing your place is issued, Saturn sells STRC in the secondary market in batches, and the USDat it secures is distributed pro rata.

The official expectation is three to seven days, with a substantial reduction stated after the V2 upgrade. If you would rather not wait, you sell in the secondary market, but the sUSDat price CoinGecko showed on August 20, 2026 was $0.976346, below the vault's internal rate on the same day.

Are minting and redemption running right now

The backing of USDat has been migrating to a different M0 issuer since 11 a.m. ET on August 19, 2026, with completion expected on August 26, 2026. The project announced that minting and redemption stop during the first stage of the migration, and that from August 20 to 26 minting resumes while redemption may remain restricted until completion.

The composition is moving on the reserve data side as well. On August 18, 2026 tokenized US Treasuries made up 100%, but by August 20 that share had fallen to 87.21%, with PYUSDx accounting for 12.79%.

PYUSDx is a framework for issuing a token backed by PYUSD on M0's infrastructure. The issuer is MoonPay Digital Assets Limited, and MoonPay states explicitly that it is not the PYUSD issued by PayPal and Paxos.

The migration notice does not name the issuer being migrated to, and the official documentation still describes the reserves as 100% tokenized US Treasuries.

What is written in the "terms of use"

The page the project points to as "Terms and disclosures" does not contain terms of service. Its contents are a privacy policy template based on Canadian privacy law, with placeholders left in from before it was filled in, and no governing law or dispute resolution provisions.

The conditions that do exist are in the referral program terms, dated May 11, 2026, which cap liability at $100 and set disputes for arbitration in the British Virgin Islands.

How far do positions stack up when you chase multipliers

Because the multiplier on simple holding is kept low and the high multipliers are concentrated in liquidity provision and YT holdings, the further you chase multipliers the more your positions overlap across several protocols. Protos reported that a setup taking fixed yield on Pendle and borrowing USDC at 1.59% on Morpho to recycle it reached the order of 39% a year.

In a phase where STRC declines, that stacking can produce a chain of forced selling.

Both co-founders are University of Pennsylvania graduates. CEO Kevin Li handled research at the on-chain analytics firm Artemis and at ParaFi Capital.

In an interview published by his former employer Artemis, he said he "realized I wanted to pursue this idea full time, so I left to start a stablecoin and yield-bearing RWA protocol."

On August 13, 2026, Ondo Finance made a strategic investment and announced a partnership to bring Ondo's tokenized STRC (STRCon) into sUSDat. The amount, the stake, and the timing of the rollout are all undisclosed.

Whether the bet on pulling in an outside cash flow is working cannot be measured by whether the dividend arrived. Multiplying the 816,876 shares the project discloses by the on-chain price gives a figure that matches the reserve valuation returned by the official API within 0.06%, so the existence of the backing itself can be verified independently.

Even so, the reason one share has not returned to its level at deposit is that the backing is a security trading below its $100 par value.

The project discloses that more than 5,000 participants hold positions of $10 or more, and dividing total deposits by that floor gives a per-person figure in the $30,000s, which is the upper bound on the average. Given that the high multipliers are concentrated in Curve liquidity provision and Pendle YT holdings, there is at present no visible basis for the same depth remaining once the rewards stop.

The official documentation still says the reserves are tokenized US Treasuries only and that STRC dividends are monthly. The actual reserve data includes PYUSDx, and Strategy, the issuer of STRC, moved to semi-monthly payments as of July 15, 2026. The "31-day cycle" that the early-exit surcharge is tied to also comes from this monthly framing, and whether the exemption threshold is in fact still 31 days cannot be confirmed with the project.

Minting USDat requires Saturn's onboarding (identity verification and sanctions screening) and address registration. If you do not go through the review, the only route left is buying in Curve or PancakeSwap pools.

1. Prepare an EVM wallet that works on Ethereum, BNB Chain, and Monad, along with gas for each chain (ETH, BNB, MON)
2. Connect your wallet at app.saturn.credit
3. Enter referral code 'SAT-FA188092' to increase your earned points by 1.05x.
4. Obtain USDat (complete onboarding if you are minting, or buy in a Curve or PancakeSwap pool if you are not going through the review)
5. Check the collateral migration notice (redemption may be restricted until the expected completion on August 26, 2026)
6. Either hold as is, or pick a route from the 39 listed in the Strategies tab
7. Check your points and rank in the Portfolio tab (points are computed from on-chain positions, so no claim action is needed)

Can you use it from Japan

The jurisdictions the referral program terms list as excluded are the United States, the EEA, the United Kingdom, Canada, Singapore, Hong Kong, mainland China, and sanctioned jurisdictions; Japan is not on that list. The same terms, however, include a catch-all for "jurisdictions Saturn designates from time to time," and explicitly prohibit circumvention via VPN or proxy.

We could not confirm any statement from the project that reads as permitting use from Japan.

Instead of drawing dollar yield from inside crypto, Saturn draws it from the cash Strategy pays its shareholders, and in exchange places a security whose price moves behind the principal. As of August 20, 2026 that security trades below par, and one share of the vault has yet to reach its level at deposit.

What changes the shape next is the reserve composition after the collateral migration expected to complete on August 26, 2026, and whether STRC returns to somewhere near $100.
