Money — srUSD

Strata’s commodity-backed settlement dollar and the control plane for supply.

The Money engine issues srUSD, Strata’s stable digital settlement unit, and serves as the control plane that gates supply across the whole system. It is a fork of Liquity v1, extended with a global money-policy controller.

The instruments

srUSD

• Collateralized digital dollar, backed by tokenized silver reserves
• Redeemable 1:1 for USDC on-chain
• Non-yield-bearing (deliberately, to avoid securities classification)
• Not a deposit or liability of any entity
• Non-redeemable for the underlying collateral — only for USDC
• Uses: settlement, collateral, credit

srSILVER

• Tokenized representation of vaulted silver
• Backed by SPV-held reserves (direct silver allocation)
• Redeemable for USDC at spot silver value
• Non-yield-bearing
• Uses: commodity exposure, DeFi collateral

Launch capacity: ~$250M srUSD and ~$50M srSILVER.

Why non-yield-bearing

srUSD pays no yield by design. A non-yield-bearing, fully-redeemable settlement unit avoids being characterized as a security or a deposit, which keeps it usable as neutral settlement and collateral across every Strata engine.

The control plane

Every engine that can affect srUSD supply routes through a global money-policy controller and engine registry, which enforce caps, throttles, and issuance gating. This is why Money is described as the system’s control plane rather than just a stablecoin.
