USDS (Sky)

The short answer

USDS inherits Maker's mechanism and its record: over-collateralised, on-chain and peg-stable through every crisis since 2017, with a savings rate paid directly by the protocol. A meaningful share of backing is now off-chain credit whose counterparties holders cannot verify, and the new token includes freeze functionality DAI never had.

What we liked

  • Collateral positions are visible on-chain in real time
  • Savings rate paid directly by the protocol
  • Permissionless redemption through the protocol's own mechanisms

Where it falls short

  • Real-world asset exposure introduces opaque counterparty risk
  • Freezing capability was introduced with the Sky rebrand

USDS is what DAI became under the Sky rebrand: the same core credit mechanism, a new token, a restructured governance system, and a savings rate that has made it one of the more attractive places to hold on-chain dollars.

What is verifiable and what is not

Crypto-collateralised positions are visible on-chain: anyone can check the collateral, the debt and the ratio. Real-world asset exposure is not. Treasury holdings, private credit and structured arrangements sit with off-chain counterparties selected through governance, and holders are trusting that process rather than verifying anything. As that share has grown, the proportion of USDS you can independently check has fallen.

The savings rate

The Sky Savings Rate pays holders directly from protocol revenue, much of which now comes from treasury yield. That makes USDS a yield-bearing dollar rather than a plain one, funded by real income rather than emissions — a genuine improvement over the previous cycle's incentive-driven yields.

The freeze capability

USDS includes the ability to freeze addresses, which DAI did not. That is a deliberate governance decision reflecting regulatory pressure, and it changes the token's character. Users who chose DAI specifically because it lacked that function should know it is present here.

Who should use it

Users wanting an on-chain dollar with a native yield and the longest peg record among decentralised stablecoins, who accept off-chain exposure and the freeze function.

FAQ

What is the difference between DAI and USDS?
USDS is the rebranded successor with the same underlying mechanism, a native savings rate, and freeze functionality that DAI does not have. DAI continues to exist and is convertible.
What backs USDS?
A mixture of on-chain crypto collateral, verifiable by anyone, and off-chain real-world assets including treasuries and private credit held through counterparties selected by governance.
Where does the savings rate come from?
Protocol revenue, much of it treasury yield from real-world asset holdings, paid directly to holders rather than funded by token emissions.
Can USDS be frozen?
Yes. Unlike DAI, USDS includes freeze functionality, a governance decision made under regulatory pressure.
