STBL is a decentralized stablecoin protocol designed to bridge real-world assets (RWAs) with on-chain liquidity. Unlike conventional stablecoins that sit idle when backed by cash equivalents, STBL introduces a yield-splitting mechanism—separating principal from yield to maximize capital efficiency while preserving stability.

How STBL Works

Users deposit high-quality, yield-bearing RWAs such as tokenized U.S. Treasuries or money market funds into the protocol. In return, they receive two assets:

• USST – A dollar-pegged stablecoin, fully collateralized and designed for everyday DeFi use.
• YLD – An NFT representing the depositor’s yield claim, redeemable when USST is burned.

This model allows participants to unlock and reuse their principal by spending or redeploying USST, while still retaining rights to the underlying yield through YLD.

Solving the Idle Yield Problem

Traditional stablecoins such as USDC or USDT provide liquidity but forgo yield generated by collateral. STBL addresses this inefficiency by channeling the yield from RWAs into NFT claims, enabling users to compound returns, participate in DeFi strategies, or hold a spendable stablecoin without sacrificing income potential.

Technology & Architecture

The protocol operates on a three-token system:

• USST – A liquid, dollar-stable token fully backed by RWAs.
• YLD – A non-transferable NFT capturing accrued yield, redeemable at redemption events.
• STBL – The governance token, used to vote on collateral onboarding, risk management, and protocol upgrades.

Collateral is secured in audited smart contracts, with on-chain transparency to ensure reserves align with circulating supply.

Governance & Tokenomics

STBL token holders shape the protocol’s future through governance proposals and Snapshot-style off-chain voting. Decisions cover collateral additions, minting fees, and protocol upgrades. In its current stage, governance is supported by a foundation ensuring compliance and oversight, but the roadmap envisions full on-chain governance as the system decentralizes.

Why It Matters

By decoupling principal from yield, STBL introduces a new stablecoin paradigm where liquidity and yield are no longer mutually exclusive. This design enhances stablecoin utility in DeFi, while providing scalable dollar liquidity backed by regulated, tokenized assets such as USDY and OUSG.
