- Type: Control change
- Stage: Proposed
- Evidence: confirmed
- Materiality: material
- Event date: 2026-10-05
- Version: 1, published 2026-10-05 (first published 2026-10-05)

- Advisor-relevant: yes
- Affects: Spark Liquidity Layer (protocol); Morpho Blue (curated vaults) (protocol)

## What happened

Spark proposed four Safe owner-rotation transactions transferring guardian control to Operational GovOps and replacing the standard Morpho curator owners.

## What changed

If executed, guardian quorum becomes 2-of-3 and standard curator quorum becomes 2-of-2. Existing vault permissions would become exercisable by the incoming owners.

## What did not change

Safe addresses and vault assignments remain unchanged in the proposal. The separate Sentora curator is excluded. Fork simulations do not establish production execution.

## Confirmed

- The guardian Safe is 0xf5748bBeFa17505b2F7222B23ae11584932C908B on both chains.
- The standard curator Safe is 0x0f963A8A8c01042B69054e787E5763ABbB0646A3 on both chains.
- The proposal requires both curator rotations to be verified before either guardian handover.
- Retained guardian and sentinel powers include cancellation and, for V2 vaults, cap decreases and deallocation.
- The official record requires organizational representation, key control and personnel/custody separation checks.

## Still open

- Required governance approvals and Atlas instance reconciliation.
- All four staged transactions, production execution receipts and final owner sets.
- Incoming signer possession, organizational attribution and operational availability.
- Personnel and custody separation beyond distinct on-chain addresses.
- Whether any selected Ketju vault uses an affected curator or sentinel.

## What it means for an advisor

- Review the Spark authority map and Morpho curator diligence for the proposed handover.
- Map affected vaults to any selected exposure before asserting a client-specific curator-change trigger.
- Require chain-specific completion evidence and operating handover records before updating the authority baseline.
