How does the Earn Vault work?

The Earn Vault allows you to deposit Startale USD to earn rewards backed by short-term U.S. Treasury Bills.

APYs are designed to stay competitive while keeping the reward system sustainable for all users.

How many times can I provide liquidity?

You can provide as many positions as you like, but each deposit needs to be at least $100 to earn STAR Points.

What is the minimum liquidity required to earn STAR Points, and where can I see my STAR Points?

• You need to provide at least $100 worth of liquidity to start earning STAR Points in every new position.
• You can view your STAR Points under “Provide Liquidity.”

How are my STAR Points calculated?

• Points begin accumulating after a 30-day initial cliff period. This cliff period ensures committed liquidity providers are rewarded. You will start earning STAR Points after the first 30 days of liquidity provision, and STAR points are calculated daily based on your liquidity position size and holding duration. Longer-held positions may earn multipliers.
• 1 STAR Points for every 100 Startale USD deposited per day.
• Multipliers are reflected based on the number of days the funds are held and distributed every 30 days.

Scenario #1 Alicia provides $500 of liquidity on 1 January.

• Alicia creates one liquidity position worth $500, which is above the $100 minimum.
• From Jan 1- Jan 29, Alicia does not earn STAR Points yet.
• Starting Jan 30, Alicia begins earning 1 STAR Point per $100, which means she earns 5 STAR Points/day.
• After 60 days, boost multipliers kick in, and her daily 5 points become 5 × 1.2 = 6 STAR Points/day.
• After 180 days, it becomes 5 × 2.0 = 10 STAR Points/day.

Scenario #2 Jerad provides $300 of liquidity on 1 January (Position 1) and another $300 liquidity on 1 March (Position 2)

• From Jan 1 - Jan 29, Jerad does not earn STAR Points yet.
• From Jan 30, Jerad begins earning 1 STAR Point per $100/day → 3 STAR Points/day on Position 1.
• From March 30, Jerad begins earning 3 STAR Points/day on Position 2.

What happens when I withdraw liquidity?

Withdrawals follow a Last-In-First-Out (LIFO) method, which helps preserve your older positions with a higher multiplier.

Scenario #3 Carlos has provided liquidity on 30 April, 30 July, 30 September, and 31 October. He decided to withdraw $200 in liquidity on 2 November.

• Startale App will follow the Last-In-First-Out (LIFO) method and remove liquidity from his newest position, dated 31 October, with only $100 left.
• He will still earn points on his remaining $100 in accordance with the holding multipliers, and his other positions will remain unaffected.

What is the fee structure for the liquidity pool?

The USDSC/USDC pool operates with a 0% fee and enforces a tight range of 1–1.0001 to maintain stability.

Can I transfer or sell my STAR Points?

STAR points are not transferable.
