Comprehensive startale usd guide for on-chain yields, liquidity and STAR Points

Within the Startale ecosystem, startale usd offers users a dollar-linked digital asset that underpins payments, savings, and liquidity incentives across the app.

What is Startale USD (USDSC)?

Startale USD (USDSC) is a fully backed U.S. dollar stablecoin issued by Startale Group and built on M0‘s universal stablecoin platform. This digital dollar is backed by short-term U.S. Treasuries and issued through structures designed to keep user assets secure at all times.

Each unit of USDSC represents a claim on reserves held in bankruptcy-remote vehicles. Moreover, the structure is designed so that user assets remain separated from the issuer’s balance sheet, reducing counterparty risk for holders of the token.

How to obtain and use Startale USD

Users can get Startale USD directly through the Startale App. You can use USDC.e or ETH to purchase USDSC, and the transaction is handled natively on-chain. Once purchased, holders can immediately deploy their stablecoins across several integrated features.

After buying USDSC, there are multiple ways to use it. You can deposit into the in-app vault to earn competitive yields, provide liquidity to the Startale USD pool on Uniswap to accumulate STAR Points, or trade against other assets within the app. In addition, more USDSC use cases are expected to roll out soon in the Startale App.

Reserves, transparency and dollar equivalence

To maintain a 1:1 relationship with the U.S. dollar, each unit of Startale USD is fully backed by short-term U.S. Treasuries held in bankruptcy-remote structures. This design aims to ensure that, even in a default scenario, underlying collateral remains accessible for users.

The backing for USDSC is monitored by independent entities that continuously verify that reserves match the circulating supply on a 1:1 basis. Furthermore, users can check reserve levels and collateral composition at any time through the M0 Dashboard, which provides ongoing transparency and clear proof of solvency.

There are no lock-ups on Startale USD itself. That said, users can access and withdraw their USDSC at any time, giving them flexibility to move funds between vaults, liquidity pools, or external wallets.

Where Startale USD can be used

USDSC is designed to function as the default stablecoin within the Startale App ecosystem. It enables seamless on-chain payments, transfers, and savings across different integrated products. As the ecosystem expands, this reach is expected to grow significantly.

Within the app, users can spend USDSC by making payments in Mini Apps (coming soon) or sending funds safely to other addresses. Moreover, they can earn yields by depositing USDSC or by accumulating STAR Points through liquidity provision, and they can swap USDSC with other assets directly in the app interface.

As adoption expands, Startale USD will also be accepted by institutional partners and DeFi protocols, helping stabilize its position as the default stablecoin on Soneium. This multi-venue presence is intended to deepen liquidity and strengthen price stability around the 1 dollar target.

How the Earn Vault works

The Earn Vault allows users to deposit Startale USD and earn rewards backed by short-term U.S. Treasury Bills. Internally, the vault allocates capital to underlying instruments that mirror low-risk government debt, aiming to deliver yield while managing risk.

When the displayed APY in the Earn Vault is higher than standard market rates, it reflects that some users have chosen to earn STAR Points instead of claiming yield. In practice, this unclaimed yield can be recycled as additional return for remaining depositors, keeping APYs competitive while maintaining a sustainable reward system.

Vault rates are therefore influenced by market conditions and user behavior. However, the overarching goal is to ensure that rewards remain attractive for savers without compromising the long-term viability of the Startale ecosystem.

Understanding STAR Points

STAR Points are the in-app metric of user contribution and engagement within the Startale App. They act as a Proof of Contribution, reflecting how actively a user participates across different app features, from liquidity provision to campaigns.

Users can earn STAR Points by completing various activities, joining campaigns, and interacting with multiple features. The more active you are, the more points you accumulate over time. Moreover, STAR Points determine eligibility for future airdrops, exclusive rewards, and other special benefits only available to engaged community members.

STAR Points themselves are not transferable and cannot be sold. However, they carry value through access to potential rewards, making them a key component of the broader incentive design of Startale’s ecosystem.

Providing liquidity and earning STAR Points

To earn STAR Points via liquidity provision, users must first hold at least $100 worth of USDSC tokens. They can buy this amount using either USDC.e or ETH on Soneium by swapping through the official Startale interface at https://app.startale.com/swap. Once they hold enough USDSC, they can proceed to the liquidity module.

After signing in to the app, users should navigate to https://app.startale.com/provide-liquidity in their browser. Then they click the Deposit button, input the desired amount of USDSC, and confirm by pressing Add Liquidity. A notification pop-up must be read and accepted to finalize the transaction.

Once the deposit is complete, a confirmation page will indicate that liquidity has been successfully added to the pool. That said, STAR Points do not start immediately. Instead, users begin earning points after a 30-day waiting period. They can track deposits under the Your Positions section and monitor accrued STAR Points for each position.

Number of positions and minimum liquidity

There is no cap on how many liquidity positions a single user can open. You can provide as many separate deposits as you like, which enables laddering entry times to benefit from multiple multipliers across positions.

However, each individual deposit must be at least $100 in USDSC to qualify for STAR Points. If a deposit falls below that threshold, it will not generate points. Users can view their total STAR Points associated with liquidity activities under the Provide Liquidity section of the app.

How STAR Points from liquidity are calculated

STAR Points from liquidity provision begin accumulating only after a 30-day initial cliff. This cliff period is designed to reward committed liquidity providers rather than short-term speculators. After this period, points accrue daily based on the size and duration of each position.

The base rule is straightforward: users earn 1 STAR Point for every 100 Startale USD deposited per day. Longer-held positions may also receive multipliers, which are calculated and distributed every 30 days. These multipliers increase the effective daily points without changing the underlying liquidity amount.

To illustrate, consider Scenario #1. On 1 January, Alicia provides $500 of liquidity, creating one position that is safely above the $100 minimum. From Jan 1–Jan 29, she does not earn STAR Points because the 30-day cliff is still in effect.

Starting on Jan 30, Alicia begins earning at the base rate of 1 STAR Point per $100 per day, meaning she receives 5 STAR Points/day. After 60 days, boost multipliers activate, and her daily total becomes 5 × 1.2 = 6 STAR Points/day. After 180 days, the multiplier increases again, and her daily total becomes 5 × 2.0 = 10 STAR Points/day.

Scenario #2 shows how multiple positions work. Jerad provides $300 of liquidity on 1 January (Position 1) and another $300 on 1 March (Position 2). From Jan 1–Jan 29, he earns no STAR Points, just like Alicia.

From Jan 30, Jerad begins earning 1 STAR Point per $100 per day on Position 1, which equals 3 STAR Points/day. From March 30, after the second position passes its own 30-day cliff, Jerad begins earning an additional 3 STAR Points/day on Position 2, doubling his total from liquidity.

Withdrawals and the LIFO method

When users withdraw liquidity, the Startale App applies a Last-In-First-Out (LIFO) method. This rule systematically removes liquidity from the newest positions first, helping preserve older positions that typically have higher multipliers attached to them.

Scenario #3 illustrates this in practice. Carlos has provided liquidity on 30 April, 30 July, 30 September, and 31 October. When he decides to withdraw $200 in liquidity on 2 November, the app removes funds from his most recent deposit.

Because the LIFO rule applies, Startale removes liquidity from the 31 October position. That position ends up with only $100 remaining, which can still earn points according to its applicable multipliers. Carlos’s older positions, which likely carry stronger multipliers, remain intact and continue to accumulate STAR Points.

Liquidity pool fees and stability

The USDSC/USDC pool currently operates with a 0% fee. This structure aims to encourage deep liquidity and low-friction trading between USDSC and USDC, making it easier for users to move between these two dollar-linked assets.

Furthermore, the pool enforces a tight trading range of 1–1.0001. This narrow band is designed to maintain price stability and align USDSC closely with the value of the U.S. dollar. In effect, it helps ensure that the Startale app stablecoin behaves predictably within decentralized markets.

Support and additional questions

STAR Points themselves cannot be transferred or sold to other users. They function strictly as an in-app metric to track participation and allocate rewards within the Startale ecosystem, rather than as a freely tradable token.

If you still have questions not addressed in this FAQ, you can contact Startale Support directly. Email the team at support@startale.com, and they will help resolve issues related to USDSC purchases, liquidity provision, vault deposits, or STAR Points calculations.

In summary, startale usd brings together a fully backed stablecoin, transparent reserves, and gamified contribution rewards, offering users a unified way to save, trade, and earn across the Startale App and the broader Soneium ecosystem.
