What backs this stablecoin?

Protocol collateral system — not a fiat cash reserve attestation.

COLLATERAL SYSTEM

Shared Sky Vat / Join / PSM architecture with DAI. Do not treat USDS and DAI as separate reserve piles.

RWA EXPOSURE

Primes vaults and legacy RWA vaults appear on the protocol balance sheet. Prime-level token detail remains an open gap.

CRYPTO COLLATERAL

ETH / LST / WBTC vaults and PSM USDC sleeves lock crypto and stable collateral on-chain.

PROTOCOL CONTROL

SKY governance / UUPS upgrade path. Freeze not implemented on USDS (may be added later).
