You can obtain Startale USD directly through the Startale App. You can use USDC.e or ETH to purchase USDSC. Once purchased, you can choose how to use your USDSC:

1. Earn competitive yields through deposits into our vault
2. Provide liquidity to the Startale USD pool on Uniswap to earn STAR Points
3. Use USDSC for in-app trading
4. More USDSC use cases rolling out soon in the Startale App

Startale USD can be used throughout the Startale App ecosystem, enabling seamless on-chain payments, transfers, and savings. You can:

1. Spend – Make payments in Mini Apps (coming soon!) or send to other addresses safely
2. Earn – Deposit to earn competitive yields or to accumulate STAR Points through liquidity provision
3. Swap – Swap your USDSC with other assets within the Startale App

As adoption expands, USDSC will also be accepted by institutional partners and DeFi protocols, stabilizing its position as the default stablecoin on Soneium.

Points begin accumulating after an initial 30-day 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 how many 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.
