# Sky Savings Rate
The Sky Savings Rate (SSR) is the mechanism behind the sUSDS position available through the Osero App.
Osero App gives you access to sUSDS, while Sky Protocol sets the rate and operates the underlying savings system.
### What is the Sky Savings Rate?
The Sky Savings Rate is the variable rate earned by sUSDS. As it accrues, each sUSDS token represents more USDS over time, without requiring you to claim rewards manually.
The yield is reflected in the value of sUSDS itself, rather than paid out as separate rewards.
The rate is set through Sky Protocol governance and can change over time. The rate shown in Osero App is the current rate, not a guaranteed future return.
### Key protocol statistics
| Metric | Value |
| ----------------------- | ------- |
| Total sUSDS Supply | $4.6B |
| Total Stablecoin Supply | $10.01B |
| Total Collateral | $13.84B |
| Total Instant Liquidity | $4.2B |
| Total Risk Capital | $183.9M |
*Data as of July 27, 2026.*
These figures are snapshots and can change as protocol positions and parameters are updated.
### What backs the Sky Savings Rate?
The rate is supported by income generated from a mix of onchain and offchain assets.
| Asset class | Allocation | Example counterparties |
| ----------------------------- | ---------- | -------------------------------- |
| USDC Stablecoins | 48.63% | Coinbase Prime |
| Onchain Crypto-Backed Lending | 19.04% | Morpho, SparkLend, Aave/Horizon |
| Short Duration Treasury Bills | 15.95% | BlackRock, Janus Henderson |
| OTC Crypto-Backed Lending | 9.90% | Maple, Galaxy, Anchorage Digital |
| AAA Corporate Debt | 5.01% | BNY Mellon, Janus Henderson |
| Other | 1.47% | Apollo |
*Data as of July 27, 2026.*
The allocation spreads exposure across several sources, but it does not remove asset, counterparty, market, or liquidity risk.

### How Osero App provides access
Osero App lets you deposit a supported stablecoin from a supported network and receive sUSDS on Ethereum. Depending on the stablecoin and network, Osero may use Enso or LI.FI to complete the route.
Before signing, you can review the amount you’re depositing, the expected sUSDS output, the route, and any fees. Supported options may change over time, and the latest options are always shown in the Osero App.
For the complete deposit and withdrawal process, see [How Osero App Works](/osero-app/osero-app/how-osero-app-works.md).
### Sky Protocol’s risk framework
Sky uses a layered capital structure designed to absorb potential losses. Agents provide **Junior Risk Capital** for the positions they manage, while Sky provides **Senior Risk Capital** as an additional layer of protection.
If a relevant position suffers a loss, it is intended to be absorbed in the following order:
This structure can mitigate some losses, but it does not guarantee that users will not lose funds.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.osero.org/osero-app/sky-foundations/sky-savings-rate.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
