USST: The Stablecoin

USST is the stablecoin of the STBL ecosystem. It is pegged 1:1 to the US dollar and fully backed by tokenized real-world assets (RWAs) such as Treasury Bills, Money Market Funds etc.

Unlike first-generation stablecoins, USST separates liquidity from yield. This means:

  • USST stays liquid and stable — you can use it freely across DeFi or payments.
  • Yield is captured separately through YLD NFT, so holding USST does not require lockups or staking.

Key Properties​

  • USD-Pegged: Always redeemable 1:1.
  • RWA-Backed: Collateral comes from regulated, tokenized money-market instruments.
  • Overcollateralized: Risk and haircut models ensure solvency and peg stability.
  • Fully Liquid: USST can be transferred, traded, or used in DeFi strategies without giving up the underlying yield.
  • Composable: Designed to integrate easily across DeFi and CeFi ecosystems.

How USST is Minted​

  1. Collateralize RWAs: Deposit eligible tokenized assets such as USDY, OUSG, or BUIDL.
  2. Mint USST + YLD: For every deposit, USST is minted as the stablecoin and YLD as the yield claim.
  3. Use USST Freely: Spend, transfer, trade, or deploy in strategies while YLD accrues yield in parallel.

Why USST Matters​

USST represents the next step in stablecoin design:

  • It proves that stablecoins can remain liquid while yield is separated.
  • It unlocks programmatic capital — stablecoins that are not just static money, but building blocks for financial applications.
  • It forms the foundation for ecosystem stablecoins powered by USST, tailored for specific protocols, treasuries, and communities.

USST is stable, liquid, and transparent — the backbone of Stablecoin 2.0.
