# Sky proposes permissioned automation of stUSDS rates and limits

> The proposed operating model adds an automated off-chain calculator and on-chain meta-parameter registry. Soter Labs recommends tightening each permitted rate step from 15 to 5 percentage points during the transition.

## What happened

Sky contributors published a concrete proposal to authorize a TechOps keeper to calculate and submit stUSDS rates, supply caps and borrowing ceilings.

## What changed

The proposed operating model adds an automated off-chain calculator and on-chain meta-parameter registry. Soter Labs recommends tightening each permitted rate step from 15 to 5 percentage points during the transition.

## What did not change

The proposal uses the existing governance-bounded StUsdsRateSetter. Keeper authorization, automated submissions and the proposed limit reductions are not established as executed.

## Confirmed

- The proposal names StUsdsRateSetter 0x30784615252B13E1DbE2bDf598627eaC297Bf4C5.
- The official scope describes a deployed ValueRegistry at 0xcDb55A799A9B9eAe22Ed0E13037bb6D2E3f1d080.
- Soter Labs identifies the registry operator as a 2-of-3 multisig controlled by its GovOps operators.
- TechOps supplies keeper address 0x068F9c8F33E13c18B852877A5D8Ec61504971376.
- The calculation algorithm remains closed-source; governance-defined setter limits remain the proposed on-chain protection.

## Still open

- October 8 spell authorization and final setter limits.
- Initial registry configuration and subsequent keeper enablement.
- First successful keeper transaction and operating handover.
- Independent reproducibility of the closed-source rate calculation.

## What it means for an advisor

- Review Sky’s diligence file for the new operator and meta-parameter control dependencies.
- Distinguish stUSDS risk-capital mechanics from ordinary sUSDS savings in exposure descriptions.
- Verify execution and first submissions before describing automation or tighter limits as operative.
