What is StoneYield?

StoneYield is a hedging network on BNB Chain that blends institutional-grade guardrails with DeFi composability. It mints sUSDC, a soul-bound claim on hedged deposits, and allocates it across curated strategies. When portability is needed, the position can be wrapped 1:1 into STUSD, a transferable twin backed by the original sUSDC.

sUSDC: The Soul-Bound Core

Every USDC deposit mints sUSDC straight to the depositor:

• Locked to wallet – non-transferable, closing off flash-loan/sandwich angles.
• Predictable unlocks – preset lock menus (7 / 30 / 90 days) secure strategies.
• Direct yield – harvested APY credits the holding wallet.

STUSD: Portable Liquidity

Desks can wrap sUSDC into STUSD at parity via the wrapper:

• DeFi/DEX ready – works across AMMs and lending rails.
• Fully backed – each STUSD maps to its underlying sUSDC.
• Zero disruption – unwrap snaps back to the protected position.

Operating Flow

1. Deposit USDC into StoneYield.
2. Get soul-bound sUSDC while capital runs through hedged strategies.
3. Wrap to STUSD when liquidity is needed.
4. Receive 93%+ of harvested APY (protocol retains a small ops fee).
5. Request unlocks based on your selected schedule.

Architecture Pillars

• Security-first: multisig controls, mint throttles, audited code.
• Transparency: live metrics, unlock timelines, wallet KPIs.
• Composability: STUSD moves broadly; sUSDC quarantines risk.
